Absolute idealism

From Wikipedia, the free encyclopedia

Absolute idealism is an ontologically monistic philosophy chiefly associated with G. W. F. Hegel and Friedrich Schelling, both of whom were German idealist philosophers in the 19th century. The label has also been attached to others such as Josiah Royce, an American philosopher who was greatly influenced by Hegel's work, and the British idealists.

A form of idealism, absolute idealism is Hegel's account of how being is ultimately comprehensible as an all-inclusive whole (das Absolute). Hegel asserted that in order for the thinking subject (human reason or consciousness) to be able to know its object (the world) at all, there must be in some sense an identity of thought and being. Otherwise, the subject would never have access to the object and we would have no certainty about any of our knowledge of the world.

To account for the differences between thought and being, however, as well as the richness and diversity of each, the unity of thought and being cannot be expressed as the abstract identity "A=A". Absolute idealism is the attempt to demonstrate this unity using a new "speculative" philosophical method, which requires new concepts and rules of logic. According to Hegel, the absolute ground of being is essentially a dynamic, historical process of necessity that unfolds by itself in the form of increasingly complex forms of being and of consciousness, ultimately giving rise to all the diversity in the world and in the concepts with which we think and make sense of the world.

The absolute idealist position dominated philosophy in nineteenth-century Britain and Germany, while exerting significantly less influence in the United States. The absolute idealist position should be distinguished from the subjective idealism of Berkeley, the transcendental idealism of Kant, or the post-Kantian transcendental idealism (also known as critical idealism) of Fichte and of the early Schelling.

Schelling and Hegel's Absolute

Dieter Henrich characterized Hegel's conception of the absolute as follows: "The absolute is the finite to the extent to which the finite is nothing at all but negative relation to itself" (Henrich 1982, p. 82). As Bowie describes it, Hegel's system depends upon showing how each view and positing of how the world really has an internal contradiction: "This necessarily leads thought to more comprehensive ways of grasping the world, until the point where there can be no more comprehensive way because there is no longer any contradiction to give rise to it."

For Hegel, the interaction of opposites generates, in a dialectical fashion, all concepts we use in order to understand the world. Moreover, this development occurs not only in the individual mind, but also throughout history. In The Phenomenology of Spirit, for example, Hegel presents a history of human consciousness as a journey through stages of explanations of the world. Each successive explanation created problems and oppositions within itself, leading to tensions which could only be overcome by adopting a view that could accommodate these oppositions in a higher unity.

For Kant, reason was only for us, and the categories only emerged within the subject. However, for Hegel, reason is embodied, or immanent within being and the world. Reason is immanent within nature, and spirit emerges out of nature. Spirit is self-conscious reason knowing itself as reason.

The aim of Hegel was to show that we do not relate to the world as if it is other from us, but that we continue to find ourselves embedded in that world. With the realization that both mind and world are ordered according to the same rational principles, our access to the world has been made secure, a security which had been lost in Kant's proclamation that the thing-in-itself (Ding an sich) was ultimately inaccessible.

The importance of 'love' within the formulation of the absolute has also been cited by Hegel throughout his works:

The life of God — the life which the mind apprehends and enjoys as it rises to the absolute unity of all things — may be described as a play of love with itself; but this idea sinks to an edifying truism, or even to a platitude, when it does not embrace in it the earnestness, the pain, the patience, and labor, involved in the negative aspect of things.

Yet Hegel did not see Christianity per se as the route through which one reaches the absolute, but used its religious system as an historical exemplar of absolute spirit. Arriving at such an absolute was the domain of philosophy and theoretical inquiry. For Hegel speculative philosophy presented the religious content in an elevated, self-aware form.

Hegel's position is a critical transformation of the concept of the absolute advanced by Friedrich Wilhelm Joseph von Schelling (1775–1854), who argued for a philosophy of Identity:

‘Absolute identity’ is, then, the link of the two aspects of being, which, on the one hand, is the universe, and, on the other, is the changing multiplicity which the knowable universe also is. Schelling insists now that “The I think, I am, is, since Descartes, the basic mistake of all knowledge; thinking is not my thinking, and being is not my being, for everything is only of God or the totality” (SW I/7, p. 148), so the I is ‘affirmed’ as a predicate of the being by which it is preceded.

Yet this absolute is different from Hegel's, which necessarily a telos or end result of the dialectic of multiplicities of consciousness throughout human history. For Schelling, the absolute is a causeless 'ground' upon which relativity (difference and similarity) can be discerned by human judgement (and thus permit 'freedom' itself) and this ground must be simultaneously not of the 'particular' world of finites but also not wholly different from them (or else there would be no commensurability with empirical reality, objects, sense data, etc. to be compared as 'relative' or otherwise):

The particular is determined in judgements, but the truth of claims about the totality cannot be proven because judgements are necessarily conditioned, whereas the totality is not. Given the relative status of the particular there must, though, be a ground which enables us to be aware of that relativity, and this ground must have a different status from the knowable world of finite particulars. At the same time, if the ground were wholly different from the world of relative particulars the problems of dualism would recur. As such the absolute is the finite, but we do not know this in the manner we know the finite. Without the presupposition of ‘absolute identity’, therefore, the evident relativity of particular knowledge becomes inexplicable, since there would be no reason to claim that a revised judgement is predicated of the same world as the preceding — now false — judgement.

In both Schelling and Hegel's 'systems' (especially the latter), the project aims towards a completion of metaphysics in such a way as to prioritize rational thinking (Vernuft), individual freedom, and philosophical and historical progress into a unity. Inspired by the system-building of previous Enlightenment thinkers like Immanuel Kant, Schelling and Hegel pushed idealism into new ontological territory (especially notable in Hegel's The Science of Logic (1812-16)), wherein a 'concept' of thought and its content are not distinguished, as Redding describes it:

While opinions divide as to how Hegel's approach to logic relates to that of Kant, it is important to grasp that for Hegel logic is not simply a science of the form of our thoughts. It is also a science of actual content as well, and as such has an ontological dimension.

Therefore, syllogisms of logic like those espoused in the ancient world by Aristotle and crucial to the logic of Medieval philosophy, became not simply abstractions like mathematical equations but ontological necessities to describe existence itself, and therefore to be able to derive 'truth' from such existence using reason and the dialectic method of understanding. Whereas rationality was the key to completing Hegel's philosophical system, Schelling could not accept the absolutism prioritzed to Reason. Bowie elaborates on this:

Hegel's system tries to obviate the facticity of the world by understanding reason as the world's immanent self-articulation. Schelling, in contrast, insists that human reason cannot explain its own existence, and therefore cannot encompass itself and its other within a system of philosophy. We cannot, [Schelling] maintains, make sense of the manifest world by beginning with reason, but must instead begin with the contingency of being and try to make sense of it with the reason which is only one aspect of it and which cannot be explained in terms of its being a representation of the true nature of being.

Schelling's skepticism towards the prioritization of reason in the dialectic system constituting the Absolute, therefore pre-empted the vast body of philosophy that would react against Hegelianism in the modern era. Schelling's view of reason, however, was not to discard it, as would Nietzsche, but on the contrary, to use nature as its embodiment. For Schelling, reason was an organic 'striving' in nature (not just anthropocentric) and this striving was one in which the subject and the object approached an identity. Schelling saw reason as the link between spirit and the phenomenal world, as Lauer explains: "For Schelling [...] nature is not the negative of reason, to be submitted to it as reason makes the world its home, but has since its inception been turning itself into a home for reason." In Schelling's Further Presentation of My System of Philosophy (Werke Ergänzungsband I, 391-424), he argued that the comprehension of a thing is done through reason only when we see it in a whole. So Beiser (p. 17) explains:

The task of philosophical construction is then to grasp the identity of each particular with the whole of all things. To gain such knowledge we should focus upon a thing by itself, apart from its relations to anything else; we should consider it as a single, unique whole, abstracting from all its properties, which are only its partial aspects, and which relate it to other things. Just as in mathematical construction we abstract from all the accidental features of a figure (it is written with chalk, it is on a blackboard) to see it as a perfect exemplar of some universal truth, so in philosophical construction we abstract from all the specific properties of an object to see it in the absolute whole.

Hegel's doubts about intellectual intuition's ability to prove or legitimate that the particular is in identity with whole, led him to progressively formulate the system of the dialectic, now known as the Hegelian dialectic, in which concepts like the Aufhebung came to be articulated in the Phenomenology of Spirit (1807). Beiser (p. 19) summarizes the early formulation as follows:

a) Some finite concept, true of only a limited part of reality, would go beyond its limits in attempting to know all of reality. It would claim to be an adequate concept to describe the absolute because, like the absolute, it has a complete or self-sufficient meaning independent of any other concept.

b) This claim would come into conflict with the fact that the concept depends for its meaning on some other concept, having meaning only in contrast to its negation. There would then be a contradiction between its claim to independence and its de facto dependence upon another concept.

c) The only way to resolve the contradiction would be to reinterpret the claim to independence, so that it applies not just to one concept to the exclusion of the other but to the whole of both concepts. Of course, the same stages could be repeated on a higher level, and so on, until we come to the complete system of all concepts, which is alone adequate to describe the absolute.

Hegel's innovation in the history of German Idealism was for a self-consciousness or self-questioning, that would lead to a more inclusive, holistic rationality of the world. The synthesis of one concept, deemed independently true per se, with another contradictory concept (e.g. the first is in fact dependent on some other thing), leads to the history of rationality, throughout human (largely European) civilization. For the German Idealists like Fichte, Schelling and Hegel, the extrapolation or universalization of the human process of contradiction and reconciliation, whether conceptually, theoretically, or emotionally, were all movements of the universe itself. It is understandable then, why so many philosophers saw deep problems with Hegel's all-encompassing attempt at fusing anthropocentric and Eurocentric epistemology, ontology, and logic into a singular system of thought that would admit no alternative.

Neo-Hegelianism

Neo-Hegelianism is a school (or schools) of thought associated and inspired by the works of Hegel.

It refers mainly to the doctrines of an idealist school of philosophers that were prominent in Great Britain and in the United States between 1870 and 1920. The name is also sometimes applied to cover other philosophies of the period that were Hegelian in inspiration—for instance, those of Benedetto Croce and of Giovanni Gentile.

Hegelianism after Hegel

Although Hegel died in 1831, his philosophy still remains highly debated and discussed. In politics, there was a developing schism, even before his death, between right Hegelians and left Hegelians. The latter specifically took on political dimensions in the form of Marxism.

In the philosophy of religion, Hegel's influence soon became very powerful in the English-speaking world. The British school, called British idealism and partly Hegelian in inspiration, included Thomas Hill Green, Bernard Bosanquet, F. H. Bradley, William Wallace, and Edward Caird. It was importantly directed towards political philosophy and political and social policy, but also towards metaphysics and logic, as well as aesthetics.

America saw the development of a school of Hegelian thought move toward pragmatism.

German twentieth-century neo-Hegelians

In Germany there was a neo-Hegelianism (Neuhegelianismus) of the early twentieth century, partly developing out of the Neo-Kantians. Richard Kroner wrote one of its leading works, a history of German idealism from a Hegelian point of view.

Other notable neo-Hegelians

Criticisms

Exponents of analytic philosophy, which has been the dominant form of Anglo-American philosophy for most of the last century, have criticised Hegel's work as hopelessly obscure. Existentialists also criticise Hegel for ultimately choosing an essentialistic whole over the particularity of existence. Epistemologically, one of the main problems plaguing Hegel's system is how these thought determinations have bearing on reality as such. A perennial problem of his metaphysics seems to be the question of how spirit externalises itself and how the concepts it generates can say anything true about nature. At the same time, they will have to, because otherwise Hegel's system concepts would say nothing about something that is not itself a concept and the system would come down to being only an intricate game involving vacuous concepts.

Schopenhauer

Schopenhauer noted that Hegel created his absolute idealism after Kant had discredited all proofs of God's existence. The Absolute is a non-personal substitute for the concept of God. It is the one subject that perceives the universe as one object. Individuals share in parts of this perception. Since the universe exists as an idea in the mind of the Absolute, absolute idealism copies Spinoza's pantheism in which everything is in God or Nature.

Moore and Russell

Famously, G. E. Moore’s rebellion against absolutism found expression in his defense of common sense against the radically counter-intuitive conclusions of absolutism (e.g. time is unreal, change is unreal, separateness is unreal, imperfection is unreal, etc.). G. E. Moore also pioneered the use of logical analysis against the absolutists, which Bertrand Russell promulgated and used in order to begin the entire tradition of analytic philosophy with its use against the philosophies of his direct predecessors. In recounting his own mental development Russell reports, "For some years after throwing over [absolutism] I had an optimistic riot of opposite beliefs. I thought that whatever Hegel had denied must be true." (Russell in Barrett and Adkins 1962, p. 477) Also:

G.E. Moore took the lead in the rebellion, and I followed, with a sense of emancipation. [Absolutism] argued that everything common sense believes in is mere appearance. We reverted to the opposite extreme, and thought that everything is real that common sense, uninfluenced by philosophy or theology, supposes real.

— Bertrand Russell; as quoted in Klemke 2000, p.28

Pragmatism

Particularly the works of William James and F. C. S. Schiller, both founding members of pragmatism, made lifelong assaults on Absolute Idealism. James was particularly concerned with the monism that Absolute Idealism engenders, and the consequences this has for the problem of evil, free will, and moral action. Schiller, on the other hand, attacked Absolute Idealism for being too disconnected with our practical lives, and argued that its proponents failed to realize that thought is merely a tool for action rather than for making discoveries about an abstract world that fails to have any impact on us.

20th century

Absolute idealism has greatly altered the philosophical landscape. Paradoxically, (though, from a Hegelian point of view, maybe not paradoxically at all) this influence is mostly felt in the strong opposition it engendered. Both logical positivism and Analytic philosophy grew out of a rebellion against Hegelianism prevalent in England during the 19th century. Continental phenomenology, existentialism and post-modernism also seek to 'free themselves from Hegel's thought'.

Martin Heidegger, one of the leading figures of Continental philosophy in the 20th century, sought to distance himself from Hegel's work. One of Heidegger's philosophical themes in Being and Time was "overcoming metaphysics," aiming to distinguish his book from Hegelian tracts. After the 1927 publication, Heidegger's "early dismissal of them [German idealists] gives way to ever-mounting respect and critical engagement." He continued to compare and contrast his philosophy with Absolute idealism, principally due to critical comments that certain elements of this school of thought anticipated Heideggerian notions of "overcoming metaphysics."

Quietism (philosophy)

From Wikipedia, the free encyclopedia
Philosophical quietists want to release humanity from deep perplexity that philosophical contemplation often causes.

Quietism in philosophy sees the role of philosophy as broadly therapeutic or remedial. Quietist philosophers believe that philosophy has no positive thesis to contribute, but rather that its value is in defusing confusions in the linguistic and conceptual frameworks of other subjects, including non-quietist philosophy. For quietists, advancing knowledge or settling debates (particularly those between realists and non-realists) is not the job of philosophy, rather philosophy should liberate the mind by diagnosing confusing concepts.

Status within philosophy

Crispin Wright said that "Quietism is the view that significant metaphysical debate is impossible." It has been described as "the view or stance that entails avoidance of substantive philosophical theorizing and is usually associated with certain forms of skepticism, pragmatism, and minimalism about truth. More particularly, it is opposed to putting forth positive theses and developing constructive arguments."

Quietism by its nature is not a philosophical school as understood in the sense of a systematic body of truths. The objective of quietism is to show that philosophical positions or theories cannot solve problems, settle debates or advance knowledge.

It is often raised in discussion as an opposite position to both philosophical realism and anti-realism. Specifically, quietists deny that there is any substantial debate between the positions of realism and non-realism. There are a range of justifications for quietism about the realism debate offered by Gideon Rosen and John McDowell.

History and proponents

Ancient

Pyrrhonism represents perhaps the earliest example of an identifiably quietist position in the West. The Pyrrhonist philosopher Sextus Empiricus described Pyrrhonism as a form of philosophical therapy:

The causal principle of scepticism we say is the hope of attaining ataraxia (being unperturbed). Men of talent, troubled by the anomaly in things and puzzled as to which of them they should rather assent to, came to investigate what in things is true and what false, thinking that by deciding these issues they would attain ataraxia. The chief constitutive principle of scepticism is the claim that to every account an equal account is opposed; for it is from this, we think, that we come to hold no beliefs.

— Sextus Empiricus, Outlines of Pyrrhonism, Book I, Chapter 12

Some have identified Epicureans as another early proponent of quietism. The goal of Epicurean philosophy is the decidedly quietist objectives of aponia (freedom from pain) and ataraxia, even dismissing Stoic logic as useless.

The neo-Confucian philosopher Cheng Hao is also associated with advocating quietism. He argued that the goal of existence should be calming one's natural biases and embracing impartial tranquility. This aversion to bias is nevertheless quite distinct from Wittgenstein's position.

Contemporary

Contemporary discussion of quietism can be traced back to Ludwig Wittgenstein, whose work greatly influenced the ordinary language philosophers. While Wittgenstein himself did not advocate quietism, he expressed sympathy with the viewpoint. One of the early 'ordinary language' works, Gilbert Ryle's The Concept of Mind, attempted to demonstrate that dualism arises from a failure to appreciate that mental vocabulary and physical vocabulary are simply different ways of describing one and the same thing, namely human behaviour. J. L. Austin's Sense and Sensibilia took a similar approach to the problems of skepticism and the reliability of sense perception, arguing that they arise only by misconstruing ordinary language, not because there is anything genuinely wrong with empirical evidence. Norman Malcolm, a friend of Wittgenstein's, took a quietist approach to skeptical problems in the philosophy of mind.

More recently, the philosophers John McDowell, Irad Kimhi, Sabina Lovibond, Eric Marcus, Gideon Rosen, and to a certain degree Richard Rorty have taken explicitly quietist positions. Pete Mandik has argued for a position of qualia quietism on the hard problem of consciousness.

Varieties

Some philosophers have advanced quietism about specific subjects such as realism or truth. These positions can be held independent of one's view on quietism about the entire project of philosophy.

On realism

One may be a realist about a range of subjects within philosophy from ethics and aesthetics to science and mathematics. Realists claim that a given concept exists, has particular properties and is in some way mind independent, while non-realists deny this claim. Quietists take a third position, claiming that there is no real debate between realists and non-realists on a given subject. A version of this position espoused by John McDowell claims that the debate hinges on theses about the relationship between the mind and the world around us that are unsupported or unsupportable, and without those claims there will be no debate. Others, such as Gideon Rosen argue more specifically against individual cases of the realism debate.

On truth

Quietism about truth is a version of the identity theory of truth. Specifically, Jennifer Hornsby and John McDowell argue against any ontological gap between what we think is true and what is actually true. Quietists about truth resist the distinction between truth bearers and truthmakers as leading to a correspondence theory of truth. Rather they claim that such a distinction should be eliminated, true statements are simply one thinking truly about the world. The target of these thoughts is not a truthbearer, but rather the facts of the world themselves.

Pyrrhonism

From Wikipedia, the free encyclopedia

Pyrrhonism is an Ancient Greek school of philosophical skepticism which rejects dogma and advocates the suspension of judgement over the truth of all beliefs. It was founded by Aenesidemus in the first century BCE, and said to have been inspired by the teachings of Pyrrho and Timon of Phlius in the fourth century BCE. Pyrrhonism is best known today through the surviving works of Sextus Empiricus, writing in the late second century or early third century CE. The publication of Sextus' works in the Renaissance ignited a revival of interest in Skepticism and played a major role in Reformation thought and the development of early modern philosophy.

History

Pyrrhonism is named after Pyrrho of Elis, a Greek philosopher in the 4th century BCE who was credited by the later Pyrrhonists with forming the first comprehensive school of skeptical thought. However, ancient testimony about the philosophical beliefs of the historical Pyrrho is minimal, and often contradictory: his teachings were recorded by his student Timon of Phlius, but those works have been lost, and only survive in fragments quoted by later authors, and based on testimonies of later authors such as Cicero, Pyrrho's own philosophy as recorded by Timon may have been much more dogmatic than that of the later school who bore his name. While Pyrrhonism would become the dominant form of skepticism in the early Roman period, in the Hellenistic period, the Platonic Academy was the primary advocate of skepticism until the mid-first century BCE, when Pyrrhonism as a philosophical school was founded by Aenesidemus.

Philosophy

As with other Hellenistic philosophies such as Stoicism, Peripateticism and Epicureanism, eudaimonia is the goal of Pyrrhonism. As with Epicureanism, Pyrrhonism places the attainment of ataraxia (a state of equanimity) as the way to achieve eudaimonia. Pyrrhonists dispute that the dogmatists – which includes all of Pyrrhonism's rival philosophies – claim to have found truth regarding non-evident matters, and that these opinions about non-evident matters (i.e., dogma) are what prevent one from attaining eudaimonia. For any of these dogma, a Pyrrhonist makes arguments for and against such that the matter cannot be concluded, thus suspending judgement, and thereby inducing ataraxia.

Pyrrhonists can be subdivided into those who are ephectic (engaged in suspension of judgment), aporetic (engaged in refutation) or zetetic (engaged in seeking). An ephectic merely suspends judgment on a matter, "balancing perceptions and thoughts against one another," It is a less aggressive form of skepticism, in that sometimes "suspension of judgment evidently just happens to the sceptic". An aporetic skeptic, in contrast, works more actively towards their goal, engaging in the refutation of arguments in favor of various possible beliefs in order to reach aporia, an impasse, or state of perplexity, which leads to suspension of judgement. Finally, the zetetic claims to be continually searching for the truth but to have thus far been unable to find it, and thus continues to suspend belief while also searching for reason to cease the suspension of belief.

Modes

Although Pyrrhonism's objective is ataraxia, it is best known for its epistemological arguments. The core practice is through setting argument against argument. To aid in this, the Pyrrhonist philosophers Aenesidemus and Agrippa developed sets of stock arguments known as "modes" or "tropes."

The ten modes of Aenesidemus

Aenesidemus is considered the creator of the ten tropes of Aenesidemus (also known as the ten modes of Aenesidemus)—although whether he invented the tropes or just systematized them from prior Pyrrhonist works is unknown. The tropes represent reasons for suspension of judgment. These are as follows:

  1. Different animals manifest different modes of perception;
  2. Similar differences are seen among individual men;
  3. For the same man, information perceived with the senses is self-contradictory
  4. Furthermore, it varies from time to time with physical changes
  5. In addition, this data differs according to local relations
  6. Objects are known only indirectly through the medium of air, moisture, etc.
  7. These objects are in a condition of perpetual change in colour, temperature, size and motion
  8. All perceptions are relative and interact one upon another
  9. Our impressions become less critical through repetition and custom
  10. All men are brought up with different beliefs, under different laws and social conditions

According to Sextus, superordinate to these ten modes stand three other modes: that based on the subject who judges (modes 1, 2, 3 & 4), that based on the object judged (modes 7 & 10), that based on both subject who judges and object judged (modes 5, 6, 8 & 9), and superordinate to these three modes is the mode of relation.

The five modes of Agrippa

These "tropes" or "modes" are given by Sextus Empiricus in his Outlines of Pyrrhonism. According to Sextus, they are attributed only "to the more recent skeptics" and it is by Diogenes Laërtius that we attribute them to Agrippa. The five tropes of Agrippa are:

  1. Dissent – The uncertainty demonstrated by the differences of opinions among philosophers and people in general.
  2. Infinite regress – All proof rests on matters themselves in need of proof, and so on to infinity.
  3. Relation – All things are changed as their relations become changed, or, as we look upon them from different points of view.
  4. Assumption – The truth asserted is based on an unsupported assumption.
  5. Circularity – The truth asserted involves a circularity of proofs.

According to the mode deriving from dispute, we find that undecidable dissension about the matter proposed has come about both in ordinary life and among philosophers. Because of this we are not able to choose or to rule out anything, and we end up with suspension of judgement. In the mode deriving from infinite regress, we say that what is brought forward as a source of conviction for the matter proposed itself needs another such source, which itself needs another, and so ad infinitum, so that we have no point from which to begin to establish anything, and suspension of judgement follows. In the mode deriving from relativity, as we said above, the existing object appears to be such-and-such relative to the subject judging and to the things observed together with it, but we suspend judgement on what it is like in its nature. We have the mode from hypothesis when the Dogmatists, being thrown back ad infinitum, begin from something which they do not establish but claim to assume simply and without proof in virtue of a concession. The reciprocal mode occurs when what ought to be confirmatory of the object under investigation needs to be made convincing by the object under investigation; then, being unable to take either in order to establish the other, we suspend judgement about both.

With reference to these five tropes, that the first and third are a short summary of the earlier Ten Modes of Aenesidemus. The three additional ones show a progress in the Pyrrhonist system, building upon the objections derived from the fallibility of sense and opinion to more abstract and metaphysical grounds. According to Victor Brochard "the five tropes can be regarded as the most radical and most precise formulation of skepticism that has ever been given. In a sense, they are still irresistible today."

Criteria of action

Pyrrhonist decision making is made according to what the Pyrrhonists describe as the criteria of action holding to the appearances, without beliefs in accord with the ordinary regimen of life based on:

  1. the guidance of nature, by which we are naturally capable of sensation and thought
  2. the compulsion of the passions by which hunger drives us to food and thirst makes us drink
  3. the handing down of customs and laws by which we accept that piety in the conduct of life is good and impiety bad
  4. instruction in techne

Skeptic sayings

The Pyrrhonists devised several sayings (Greek ΦΩΝΩΝ) to help practitioners bring their minds to suspend judgment. Among these are:

  • Not more, nothing more (a saying attributed to Democritus)
  • Non-assertion (aphasia)
  • Perhaps, it is possible, maybe
  • I withhold assent
  • I determine nothing (Montaigne created a variant of this as his own personal motto, "Que sais-je?" – "what do I know?")
  • Everything is indeterminate
  • Everything is non-apprehensible
  • I do not apprehend
  • To every argument an equal argument is opposed

Texts

Except for the works of Sextus Empiricus, the texts of ancient Pyrrhonism have been lost. There is a summary of the Pyrrhonian Discourses by Aenesidemus, preserved by Photius, and a brief summary of Pyrrho's teaching by Aristocles, quoting Pyrrho's student Timon preserved by Eusebius:

'The things themselves are equally indifferent, and unstable, and indeterminate, and therefore neither our senses nor our opinions are either true or false. For this reason then we must not trust them, but be without opinions, and without bias, and without wavering, saying of every single thing that it no more is than is not, or both is and is not, or neither is nor is not.

Influence

In Ancient Greek philosophy

Skeptics in Raphael's School of Athens painting. Pyrrho is #4 and Timon #5

Pyrrhonism is often contrasted with Academic skepticism, a similar but distinct form of Hellenistic philosophical skepticism. While early Academic skepticism was influenced in part by Pyrrho, it grew more and more dogmatic until Aenesidemus broke with the Academics to revive Pyrrhonism in the first century BCE, denouncing the Academy as "Stoics fighting against Stoics." Some later Pyrrhonists, such as Sextus Empiricus, go so far as to claim that Pyrrhonists are the only real skeptics, dividing all philosophy into the dogmatists, the Academics, and the skeptics. Dogmatists claim to have knowledge, Academic skeptics claim that knowledge is impossible, while Pyrrhonists assent to neither proposition, suspending judgment on both. The second century Roman historian Aulus Gellius describes the distinction as "...the Academics apprehend (in some sense) the very fact that nothing can be apprehended, and they determine (in some sense) that nothing can be determined, whereas the Pyrrhonists assert that not even that seems to be true, since nothing seems to be true."

Sextus Empiricus also said that the Pyrrhonist school influenced and had substantial overlap with the Empiric school of medicine, but that Pyrrhonism had more in common with the Methodic school in that it "follow[s] the appearances and take[s] from these whatever seems expedient."

Although Julian the Apostate mentions that Pyrrhonism had died out at the time of his writings, other writers mention the existence of later Pyrrhonists. Pseudo-Clement, writing around the same time (c. 300-320 CE) mentions Pyrrhonists in his Homilies and Agathias even reports a Pyrrhonist named Uranius as late as the middle of the 6th century CE.

Similarities between Pyrrhonism and Indian philosophy

Nagarjuna, a Madhyamaka Buddhist philosopher whose skeptical arguments are similar to those preserved in the work of Sextus Empiricus

A number of similarities have been noted between the Pyrrhonist works of Sextus Empiricius and that of Nagarjuna, the Madhyamaka Buddhist philosopher from the 2nd or 3rd century CE. Buddhist philosopher Jan Westerhoff says "many of Nāgārjuna's arguments concerning causation bear strong similarities to classical sceptical arguments as presented in the third book of Sextus Empiricus's Outlines of Pyrrhonism," and Thomas McEvilley suspects that Nagarjuna may have been influenced by Greek Pyrrhonist texts imported into India. McEvilley argues for mutual iteration in the Buddhist logico-epistemological traditions between Pyrrhonism and Madhyamika:

An extraordinary similarity, that has long been noticed, between Pyrrhonism and Mādhyamika is the formula known in connection with Buddhism as the fourfold negation (Catuṣkoṭi) and which in Pyrrhonic form might be called the fourfold indeterminacy.

McEvilley also notes a correspondence between the Pyrrhonist and Madhyamaka views about truth, comparing Sextus' account of two criteria regarding truth, one which judges between reality and unreality, and another which we use as a guide in everyday life. By the first criteria, nothing is either true or false, but by the second, information from the senses may be considered either true or false for practical purposes. As Edward Conze has noted, this is similar to the Madhyamika Two Truths doctrine, a distinction between "Absolute truth" (paramārthasatya), "the knowledge of the real as it is without any distortion," and "Truth so-called" (saṃvṛti satya), "truth as conventionally believed in common parlance.

Some scholars have also looked farther back, to determine if any earlier Indian philosophy may have had an influence on Pyrrho. Diogenes Laërtius' biography of Pyrrho reports that Pyrrho traveled with Alexander the Great's army to India and incorporated what he learned from the Gymnosophists and the Magi that he met in his travels into his philosophical system. Pyrrho would have spent about 18 months in Taxila as part of Alexander the Great's court during Alexander's conquest of the east. Christopher I. Beckwith draws comparisons between the Buddhist three marks of existence and the concepts outlined in the "Aristocles Passage".

However, other scholars, such as Stephen Batchelor and Charles Goodman question Beckwith's conclusions about the degree of Buddhist influence on Pyrrho. Conversely, while critical of Beckwith's ideas, Kuzminsky sees credibility in the hypothesis that Pyrrho was influenced by Buddhism, even if it cannot be safely ascertained with our current information.

While discussing Christopher Beckwith's claims in Greek Buddha: Pyrrho's Encounter with Early Buddhism in Central Asia, Jerker Blomqvist states that:

On the other hand, certain elements that are generally regarded as essential features of Buddhism are entirely absent from ancient Pyrrhonism/scepticism. The concepts of good and bad karma must have been an impossibility in the Pyrrhonist universe, if "things" were ἀδιάφορα, 'without a logical self-identity', and, consequently, could not be differentiated from each other by labels such as 'good' and 'bad' or 'just' and 'unjust'. A doctrine of rebirth, reminiscent of the Buddhist one, though favored by Plato and Pythagoras, was totally alien to the Pyrrhonists. The ἀταραξία, 'undisturbedness', that the Pyrrhonists promised their followers, may have a superficial resemblance to the Buddhist nirvana, but ἀταραξία, unlike nirvana, did not involve a liberation from a cycle of reincarnation; rather, it was a mode of life in this world, blessed with μετριοπάθεια, 'moderation of feeling' or 'moderate suffering', not with the absence of any variety of pain. Kuzminski, whom Beckwith hails as a precursor of his, had largely ignored the problem with this disparity between Buddhism and Pyrrhonism.

Ajñana, which upheld radical skepticism, may have been a more powerful influence on Pyrrho than Buddhism. The Buddhists referred to Ajñana's adherents as Amarāvikkhepikas or "eel-wrigglers", due to their refusal to commit to a single doctrine. Scholars including Barua, Jayatilleke, and Flintoff, contend that Pyrrho was influenced by, or at the very least agreed with, Indian skepticism rather than Buddhism or Jainism, based on the fact that he valued ataraxia, which can be translated as "freedom from worry". Jayatilleke, in particular, contends that Pyrrho may have been influenced by the first three schools of Ajñana, since they too valued freedom from worry.

Modern

Balance scales in equal balance are a modern symbol of Pyrrhonism

The recovery and publication of the works of Sextus Empiricus, particularly a widely influential translation by Henri Estienne published in 1562, ignited a revival of interest in Pyrrhonism. Philosophers of the time used his works to source their arguments on how to deal with the religious issues of their day. Major philosophers such as Michel de Montaigne, Marin Mersenne, and Pierre Gassendi later drew on the model of Pyrrhonism outlined in Sextus Empiricus' works for their own arguments. This resurgence of Pyrrhonism has sometimes been called the beginning of modern philosophy. Montaigne adopted the image of a balance scale for his motto, which became a modern symbol of Pyrrhonism. It has also been suggested that Pyrrhonism provided the skeptical underpinnings that René Descartes drew from in developing his influential method of Cartesian doubt and the associated turn of early modern philosophy towards epistemology. In the 18th century, David Hume was also considerably influenced by Pyrrhonism, using "Pyrrhonism" as a synonym for "skepticism.".

Nietzsche was critical of Pyrrhonian ephectics.

Friedrich Nietzsche, however, criticized the "ephetics" of the Pyrrhonists as a flaw of early philosophers, who he characterized as "shy little blunderer[s] and milquetoast[s] with crooked legs" prone to overindulging "his doubting drive, his negating drive, his wait-and-see ('ephectic') drive, his analytical drive, his exploring, searching, venturing drive, his comparing, balancing drive, his will to neutrality and objectivity, his will to every sine ira et studio: have we already grasped that for the longest time they all went against the first demands of morality and conscience?"

Contemporary

Fallibilism is a modern, fundamental perspective of the scientific method, as put forth by Karl Popper and Charles Sanders Peirce, that all knowledge is, at best, an approximation, and that any scientist always must stipulate this in her or his research and findings. It is, in effect, a modernized extension of Pyrrhonism. Indeed, historic Pyrrhonists sometimes are described by modern authors as fallibilists and modern fallibilists sometimes are described as Pyrrhonists.

The term "neo-Pyrrhonism" is used to refer to modern Pyrrhonists such as Benson Mates and Robert Fogelin.

Platonism

Platonism is the philosophy of Plato and philosophical systems closely derived from it, though contemporary Platonists do not necessarily accept all doctrines of Plato. Platonism had a profound effect on Western thought. In its most basic fundamentals, Platonism affirms the existence of abstract objects, which are asserted to exist in a third realm distinct from both the sensible external world and from the internal world of consciousness, and is the opposite of nominalism. This can apply to properties, types, propositions, meanings, numbers, sets, truth values, and so on (see abstract object theory). Philosophers who affirm the existence of abstract objects are sometimes called Platonists; those who deny their existence are sometimes called nominalists. The terms "Platonism" and "nominalism" also have established senses in the history of philosophy. They denote positions that have little to do with the modern notion of an abstract object.

In a narrower sense, the term might indicate the doctrine of Platonic realism, a form of mysticism. The central concept of Platonism, a distinction essential to the Theory of Forms, is the distinction between the reality which is perceptible but unintelligible, associated with the flux of Heraclitus and studied by the likes of science, and the reality which is imperceptible but intelligible, associated with the unchanging being of Parmenides and studied by the likes of mathematics. Geometry was the main motivation of Plato, and this also shows the influence of Pythagoras. The Forms are typically described in dialogues such as the Phaedo, Symposium and Republic as perfect archetypes of which objects in the everyday world are imperfect copies. Aristotle's Third Man Argument is its most famous criticism in antiquity.

In the Republic the highest form is identified as the Form of the Good, the source of all other Forms, which could be known by reason. In the Sophist, a later work, the Forms being, sameness and difference are listed among the primordial "Great Kinds". Plato established the academy, and in the 3rd century BC, Arcesilaus adopted academic skepticism, which became a central tenet of the school until 90 BC when Antiochus added Stoic elements, rejected skepticism, and began a period known as Middle Platonism.

In the 3rd century AD, Plotinus added additional mystical elements, establishing Neoplatonism, in which the summit of existence was the One or the Good, the source of all things; in virtue and meditation the soul had the power to elevate itself to attain union with the One. Many Platonic notions were adopted by the Christian church which understood Plato's Forms as God's thoughts (a position also known as divine conceptualism), while Neoplatonism became a major influence on Christian mysticism in the West through Saint Augustine, Doctor of the Catholic Church, who was heavily influenced by Plotinus' Enneads, and in turn were foundations for the whole of Western Christian thought. Many ideas of Plato were incorporated by the Roman Catholic Church.

Philosophy

The primary concept is the Theory of Forms. The only true being is founded upon the forms, the eternal, unchangeable, perfect types, of which particular objects of moral and responsible sense are imperfect copies. The multitude of objects of sense, being involved in perpetual change, are thereby deprived of all genuine existence. The number of the forms is defined by the number of universal concepts which can be derived from the particular objects of sense. The following excerpt may be representative of Plato's middle period metaphysics and epistemology:

[Socrates:] "Since the beautiful is opposite of the ugly, they are two."

[Glaucon:] "Of course."
"And since they are two, each is one?"
"I grant that also."
"And the same account is true of the just and unjust, the good and the bad, and all the forms. Each of them is itself one, but because they manifest themselves everywhere in association with actions, bodies, and one another, each of them appears to be many."
"That's right."
"So, I draw this distinction: On one side are those you just now called lovers of sights, lovers of crafts, and practical people; on the other side are those we are now arguing about and whom one would alone call philosophers."
"How do you mean?"
"The lovers of sights and sounds like beautiful sounds, colors, shapes, and everything fashioned out of them, but their thought is unable to see and embrace the nature of the beautiful itself."
"That's for sure."
"In fact, there are very few people who would be able to reach the beautiful itself and see it by itself. Isn't that so?"
"Certainly."
"What about someone who believes in beautiful things, but doesn't believe in the beautiful itself and isn't able to follow anyone who could lead him to the knowledge of it? Don't you think he is living in a dream rather than a wakened state? Isn't this dreaming: whether asleep or awake, to think that a likeness is not a likeness but rather the thing itself that it is like?"
"I certainly think that someone who does that is dreaming."
"But someone who, to take the opposite case, believes in the beautiful itself, can see both it and the things that participate in it and doesn't believe that the participants are it or that it itself is the participants--is he living in a dream or is he awake?
"He's very much awake."

(Republic Bk. V, 475e-476d, translation G.M.A Grube)

Book VI of the Republic identifies the highest form as the Form of the Good, the cause of all other Ideas, and that on which the being and knowing of all other Forms is contingent. Conceptions derived from the impressions of sense can never give us the knowledge of true being; i.e. of the forms. It can only be obtained by the soul's activity within itself, apart from the troubles and disturbances of sense; that is to say, by the exercise of reason. Dialectic, as the instrument in this process, leading us to knowledge of the forms, and finally to the highest form of the Good, is the first of sciences. Later Neoplatonism, beginning with Plotinus, identified the Good of the Republic with the transcendent, absolute One of the first hypothesis of the Parmenides (137c-142a).

Platonist ethics is based on the Form of the Good. Virtue is knowledge, the recognition of the supreme form of the good. And, since in this cognition, the three parts of the soul, which are reason, spirit, and appetite, all have their share, we get the three virtues, Wisdom, Courage, and Moderation. The bond which unites the other virtues is the virtue of Justice, by which each part of the soul is confined to the performance of its proper function.

Platonism had a profound effect on Western thought. In many interpretations of the Timaeus Platonism, like Aristotelianism, poses an eternal universe, as opposed to the nearby Judaic tradition that the universe had been created in historical time, with its continuous history recorded. Unlike Aristotelianism, Platonism describes idea as prior to matter and identifies the person with the soul. Many Platonic notions secured a permanent place in Christianity.

At the heart of Plato's philosophy is the theory of the soul. Francis Cornford described the twin pillars of Platonism as being the theory of the Forms, on the one hand, and, on the other hand, the doctrine of the immortality of the soul. Indeed, Plato was the first person in the history of philosophy to believe that the soul was both the source of life and the mind. In Plato's dialogues, we find the soul playing many disparate roles. Among other things, Plato believes that the soul is what gives life to the body (which was articulated most of all in the Laws and Phaedrus) in terms of self-motion: to be alive is to be capable of moving yourself; the soul is a self-mover. He also thinks that the soul is the bearer of moral properties (i.e., when I am virtuous, it is my soul that is virtuous as opposed to, say, my body). The soul is also the mind: it is that which thinks in us.

We see this casual oscillation between different roles of the soul in many dialogues. First of all, in the Republic:

Is there any function of the soul that you could not accomplish with anything else, such as taking care of something (epimeleisthai), ruling, and deliberating, and other such things? Could we correctly assign these things to anything besides the soul, and say that they are characteristic (idia) of it?

No, to nothing else.

What about living? Will we deny that this is a function of the soul?

That absolutely is.

The Phaedo most famously caused problems to scholars who were trying to make sense of this aspect of Plato's theory of the soul, such as Broadie and Dorothea Frede.

More-recent scholarship has overturned this accusation arguing that part of the novelty of Plato's theory of the soul is that it was the first to unite the different features and powers of the soul that became commonplace in later ancient and medieval philosophy. For Plato, the soul moves things by means of its thoughts, as one scholar puts it, and accordingly, the soul is both a mover (i.e., the principle of life, where life is conceived of as self-motion) and a thinker.

History

Ancient philosophy

The Academy

Site of Plato's Academy in Athens

Platonism was originally expressed in the dialogues of Plato, in which the figure of Socrates is used to expound certain doctrines, that may or may not be similar to the thought of the historical Socrates, Plato's master. Plato delivered his lectures at the Platonic Academy, a precinct containing a sacred grove outside the walls of Athens. The school continued there long after Plato's death. There were three periods: the Old, Middle, and New Academy. The chief figures in the Old Academy were Speusippus (Plato's nephew), who succeeded him as the head of the school (until 339 BC), and Xenocrates (until 313 BC). Both of them sought to fuse Pythagorean speculations on number with Plato's theory of forms.

The Skeptical Academy

Around 266 BC, Arcesilaus became head of the academy. This phase, known as the Middle Academy, strongly emphasized philosophical skepticism. It was characterized by its attacks on the Stoics and their assertion of the certainty of truth and our knowledge of it. The New Academy began with Carneades in 155 BC, the fourth head in succession from Arcesilaus. It was still largely skeptical, denying the possibility of knowing an absolute truth; both Arcesilaus and Carneades argued that they were maintaining a genuine tenet of Plato.

Middle Platonism

Around 90 BC, Antiochus of Ascalon rejected skepticism, making way for the period known as Middle Platonism, in which Platonism was fused with certain Peripatetic and many Stoic dogmas. In Middle Platonism, the Platonic Forms were not transcendent but immanent to rational minds, and the physical world was a living, ensouled being, the World-Soul. Pre-eminence in this period belongs to Plutarch. The eclectic nature of Platonism during this time is shown by its incorporation into Pythagoreanism (Numenius of Apamea) and into Jewish philosophy (Philo of Alexandria).

Neoplatonism

Many Western churchmen, including Augustine of Hippo, have been influenced by Platonism.

In the third century, Plotinus recast Plato's system, establishing Neoplatonism, in which Middle Platonism was fused with mysticism. At the summit of existence stands the One or the Good, as the source of all things. It generates from itself, as if from the reflection of its own being, reason, the nous, wherein is contained the infinite store of ideas. The world-soul, the copy of the nous, is generated by and contained in it, as the nous is in the One, and, by informing matter in itself nonexistent, constitutes bodies whose existence is contained in the world-soul. Nature therefore is a whole, endowed with life and soul. Soul, being chained to matter, longs to escape from the bondage of the body and return to its original source. In virtue and philosophical thought it has the power to elevate itself above the reason into a state of ecstasy, where it can behold, or ascend to, that one good primary Being whom reason cannot know. To attain this union with the Good, or God, is the true function of human beings.

Plotinus' disciple, Porphyry, followed by Iamblichus, developed the system in conscious opposition to Christianity. The Platonic Academy was re-established during this period; its most renowned head was Proclus (died 485), a celebrated commentator on Plato's writings. The academy persisted until Roman emperor Justinian closed it in 529.

Medieval philosophy

Christianity and Platonism

Platonism has had some influence on Christianity through Clement of Alexandria and Origen, and the Cappadocian Fathers. St. Augustine was heavily influenced by Platonism as well, which he encountered through the Latin translations of Marius Victorinus of the works of Porphyry and/or Plotinus.

Platonism was considered authoritative in the Middle Ages. Platonism also influenced both Eastern and Western mysticism. Meanwhile, Platonism influenced various philosophers. While Aristotle became more influential than Plato in the 13th century, St. Thomas Aquinas's philosophy was still in certain respects fundamentally Platonic.

Modern philosophy

Renaissance

The Renaissance also saw a renewed interest in Platonic thought, including more interest in Plato himself. In 16th-, 17th-, and 19th-century England, Plato's ideas influenced many religious thinkers including the Cambridge Platonists. Orthodox Protestantism in continental Europe, however, distrusts natural reason and has often been critical of Platonism. An issue in the reception of Plato in early modern Europe was how to deal with the same-sex elements of his corpus.

Christoplatonism is a term used to refer to a dualism opined by Plato, which holds spirit is good but matter is evil, which influenced some christian churches, though the Bible's teaching directly contradicts this philosophy and thus it receives constant criticism from many teachers in the Christian Church today. According to the Methodist Church, Christoplatonism directly "contradicts the Biblical record of God calling everything He created good."

Contemporary philosophy

Modern Platonism

Apart from historical Platonism originating from thinkers such as Plato and Plotinus, we also encounter the theory of abstract objects in the modern sense.

Platonism is the view that there exist such things as abstract objects — where an abstract object is an object that does not exist in space or time and which is therefore entirely non-physical and non-mental. Platonism in this sense is a contemporary view.

Most contemporary Platonists trace their views to those of Gottlob Frege.

This modern Platonism has been endorsed in one way or another at one time or another by numerous philosophers, such as Bernard Bolzano, who argue for anti-psychologism. Plato's works have been decisively influential for 20th century philosophers such as Alfred North Whitehead and his Process Philosophy; and for the critical realism and metaphysics of Nicolai Hartmann.

Analytic

In contemporary philosophy, most Platonists trace their ideas to Gottlob Frege's influential paper "Thought", which argues for Platonism with respect to propositions, and his influential book, The Foundations of Arithmetic, which argues for Platonism with respect to numbers and is a seminal text of the logicist project. Contemporary analytic philosophers who espoused Platonism in metaphysics include Bertrand Russell, Alonzo Church, Kurt Gödel, W. V. O. Quine, David Kaplan, Saul Kripke, Edward Zalta and Peter van Inwagen. Iris Murdoch espoused Platonism in moral philosophy in her 1970 book The Sovereignty of Good.

Paul Benacerraf's epistemological challenge to contemporary Platonism has proved its most influential criticism.

Continental

In contemporary Continental philosophy, Edmund Husserl's arguments against psychologism are believed to derive from a Platonist conception of logic, influenced by Frege and his mentor Bolzano.Husserl explicitly mentioned Bolzano, G. W. Leibniz and Hermann Lotze as inspirations for his position in his Logical Investigations (1900–1). Other prominent contemporary Continental philosophers interested in Platonism in a general sense include Leo Strauss, Simone Weil, and Alain Badiou.
