TheInfoList




Sextus Empiricus ( grc-gre, Σέξτος Ἐμπειρικός; c. 160 – c. 210 AD) was a Ancient Greece, Greek Pyrrhonism, Pyrrhonist philosopher and a physician. His philosophical works are the most complete surviving account of ancient Greek and Roman Pyrrhonism, and because of the arguments they contain against the other Hellenistic philosophy, Hellenistic philosophies they are also a major source of information about those philosophies. In his medical work, as reflected by his name, tradition maintains that he belonged to the Empiric school in which Pyrrhonism was popular. However, at least twice in his writings, Sextus seems to place himself closer to the Methodic school. Little is known about Sextus Empiricus. He likely lived in Alexandria, Rome, or Athens. The Suda, a 10th-century Byzantine encyclopedia, states that he was the same person as Sextus of Chaeronea, but this identification is commonly doubted.


Writings

Diogenes Laërtius and the Suda report that Sextus Empiricus wrote ten books on Pyrrhonism. The Suda also says Sextus wrote a book ''Ethica.'' Sextus Empiricus's three surviving works are the ''Outlines of Pyrrhonism'' (Πυῤῥώνειοι ὑποτυπώσεις, ''Pyrrhōneioi hypotypōseis'', thus commonly abbreviated ''PH''), and two distinct works preserved under the same title, ''Adversus Mathematicos'' (Πρὸς μαθηματικούς, ''Pros mathematikous'' , commonly abbreviated "AM" and known as ''Against Those in the Disciplines,'' or ''Against the Mathematicians''). ''Adversus Mathematicos'' is incomplete as the text references parts that are not in the surviving text. ''Adversus Mathematicos'' also includes mentions of three other works which did not survive: * ''Medical Commentaries'' (AD I 202) * ''Empirical Commentaries'' (AM I 62) * ''Commentaries on the Soul'' which includes a discussion of the Pythagoreans' metaphysical theory of numbers (AD IV 284) and shows that the soul is nothing (AM VI 55) The surviving first six books of ''Adversus Mathematicos'' are commonly known as ''Against the Professors.'' Each book also has a traditional title; although none of these titles except ''Pros mathematikous'' and ''Pyrrhōneioi hypotypōseis'' are found in the manuscripts. ''Adversus Mathematicos'' ''I–VI'' is sometimes distinguished from ''Adversus Mathematicos'' ''VII–XI'' by using another title, ''Against the Dogmatists'' ( ''Πρὸς δογματικούς, Pros dogmatikous'') and then the remaining books are numbered as I–II, III–IV, and V, despite the fact that it is commonly inferred that what we have is just part of a larger work whose beginning is missing and it is unknown how much of the total work has been lost. The supposed general title of this partially lost work is ''Skeptical Treatises (''Σκεπτικὰ Ὑπομνήματα /Skeptika Hypomnēmata'').


Philosophy

Sextus Empiricus raised concerns which applied to all types of knowledge. He doubted the validity of problem of induction, induction long before its best known critic David Hume, and raised the regress argument against all forms of reasoning: Because of these and other barriers to acquiring true beliefs, Sextus Empiricus advises that we should suspend judgment about virtually all beliefs; that is to say, we should neither affirm any belief as true nor deny any belief as false. This view is known as Pyrrhonian skepticism, as distinguished from Academic skepticism as practiced by Carneades, which, according to Sextus, denies knowledge altogether. Sextus did not deny the possibility of knowledge. He criticizes the Academic skeptic's claim that nothing is knowable as being an affirmative belief. Instead, Sextus advocates simply giving up belief; in other words, suspending judgment (epoché) about whether or not anything is knowable. Only by suspending judgment can we attain a state of ataraxia (roughly, 'peace of mind'). Sextus did not think such a general suspension of judgment to be impractical, since we may live without any beliefs, acting by habit. Sextus allowed that we might affirm claims about our experience (e.g., reports about our feelings or sensations). That is, for some claim X that I feel or perceive, it could be true to say "it seems to me now that X." However, he pointed out that this does not imply any objective knowledge of external reality. Though I might know that the honey I eat at a certain moment tastes sweet to me, this is merely a subjective judgment, and as such may not tell me anything true about the honey itself. Interpretations of Sextus's philosophy along the above lines have been advocated by scholars such as Myles Burnyeat, Jonathan Barnes, and Benson Mates. Michael Frede, however, defends a different interpretation, according to which Sextus does allow beliefs, so long as they are not derived by reason, philosophy or speculation; a skeptic may, for example, accept common opinions in the skeptic's society. The important difference between the skeptic and the dogmatist is that the skeptic does not hold his beliefs ''as a result of rigorous philosophical investigation.'' In ''Against the Ethicists'', Sextus in fact directly says that "the Skeptic does not conduct his life according to philosophical theory (so far as regards this he is inactive), but as regards the non-philosophical regulation of life he is capable of desiring some things and avoiding others." (XI, 165). Thus, on this interpretation (and as per Sextus' own words), the skeptic may well entertain the belief that God does or does not exist or that virtue is good. But he will not believe that such claims are true on the basis of ''reasons'' since, as far as the skeptic is aware, no reason for assenting to such claims has yet been shown to be "any more" credible than the reasons for their denial. (XIX) It must also be remembered that by "belief" (i.e., dogma) Sextus means "assent to something non-evident [ἄδηλος, ''adēlos'']" (PH I, 16). And by "non-evident" he means things which lie beyond appearances (i.e., ''phantasiai''), and thus are beyond proof or disproof, such as the existence and/or nature of causality, time, motion, or even proof itself. Thus, the skeptic will, for example, believe the proposition that "Dion is in the room" if sense-data and ordinary reasoning led to the emergence of such a belief. On the other hand, if he were to "strongly" assert that Dion was "really" in the room, then he may be met with opposing arguments of equal psychological force against the self-same proposition and experience mental disquietude as a result. Thus, the Pyrrhonian does not assent to the proposition "Dion is in the room" in a dogmatic way as that would purport to describe a non-evident reality which lies beyond the "appearance" [φαινόμενον, phainomenon] of Dion being in the room. The Skeptic simply goes along with the appearance just as "a child is persuaded by...his teacher." (PH I, 229). It is for this reason then that Sextus says the Skeptic lives undogmatically in accordance with appearances and also according to a "fourfold regimine of life" which includes the guidance of nature, compulsion of ''pathe'' (feelings), laws and customs, and instruction in arts and crafts. The Skeptic follows this course of life while suspending judgment concerning the ultimate truth of the non-evident matters debated in philosophy and the sciences (PH I, 17). Thus, the Pyrrhonist achieves ataraxia not by casting certain judgments about appearances but rather through his refined ability to "oppose appearances to judgments" such that he is "brought firstly to a state of mental suspense and next to ataraxia.'" (IV, 8)


The ten modes of Pyrrhonism

Pyrrhonism is more of a mental attitude or therapy than a theory. It involves setting things in opposition and owing to the equipollence of the objects and reasons, one suspends judgement. "We oppose either appearances to appearances or objects of thought to objects of thought or ''alternando.''" The ten modes induce suspension of judgement and in turn a state of mental suspense followed by ''ataraxia.'' If ever one is in a position in which they are unable to refute a theory, Pyrrhonists reply "Just as, before the birth of the founder of the School to which you belong, the theory it holds was not as yet apparent as a sound theory, although it was really in existence, so likewise it is possible that the opposite theory to that which you now propound is already really existent, though not yet apparent to us, so that we ought not as yet to yield assent to this theory which at the moment seems to be valid." These ten ''modes'' or ''tropes'' were originally listed by Aenesidemus (see The ten modes of Aenesidemus). # "The same impressions are not produced by the same objects owing to the differences in animals." # The same impressions are not produced by the same objects owing to the differences among human beings. # The same impressions are not produced by the same objects owing to the differences among the senses. # Owing to the "circumstances, conditions or dispositions," the same objects appear different. These are "states that are natural or unnatural, with waking or sleeping, with conditions due to age, motion or rest, hatred or love, emptiness or fullness, drunkenness or soberness, predispositions, confidence or fear, grief or joy." # "Based on positions, distances, and locations; for owing to each of these the same objects appear different." For example, "the same porch when viewed from one of its corners appears curtailed, but viewed from the middle symmetrical on all sides; and the same ship seems at a distance to be small and stationary, but from close at hand large and in motion ; and the same tower from a distance appears round but from a near point quadrangular." # “We deduce that since no object strikes us entirely by itself, but along with something else, it may perhaps be possible to say what the mixture compounded out of the external object and the thing perceived with it is like, but we would not be able to say what the external object is like by itself." # "Based, as we said, on the quantity and constitution of the underlying objects, meaning generally by "constitution" the manner of composition." So, for example, goat horn appears black when intact and appears white when ground up. Snow appears white when frozen and translucent as a liquid. # "Since all things appear relative, we will suspend judgment about what things exist absolutely and really existent. Do things which exist "differentially" as opposed to those things that have a distinct existence of their own, differ from relative things or not? If they do not differ, then they too are relative; but if they differ, then, since everything which differs is relative to something..., things which exist absolutely are relative." # "Based on constancy or rarity of occurrence." The sun is more amazing than a comet, but because we see and feel the warmth of the sun daily and the comet rarely, the latter commands our attention. # "There is a Tenth Mode, which is mainly concerned with Ethics, being based on rules of conduct, habits, laws, legendary beliefs, and dogmatic conceptions." Superordinate to these ten modes stand three other modes: * I: that based on the subject who judges (modes 1, 2, 3 & 4). * II: that based on the object judged (modes 7 & 10). * III: that based on both subject who judges and object judged (modes 5, 6, 8 & 9) Superordinate to these three modes is the mode of relation.


Similarity with Madhyamaka Buddhism

Because of the high degree of similarity between the surviving works of Sextus Empiricus and those of the Madhyamaka, Madhyamaka Buddhist philosopher Nagarjuna, Thomas McEvilley and Matthew Neale suspect that Nagarjuna and Sextus Empiricus were referencing some of the same earlier Pyrrhonist texts in developing their works.


Legacy

An influential Latin translation of Sextus's ''Outlines'' was published by Henricus Stephanus in Geneva in 1562, and this was followed by a complete Latin Sextus with Gentian Hervet as translator in 1569. Petrus and Jacobus Chouet published the Greek text for the first time in 1621. Stephanus did not publish it with his Latin translation either in 1562 or in 1569, nor was it published in the reprint of the latter in 1619. Sextus's ''Outlines'' were widely read in Europe during the 16th, 17th and 18th centuries, and had a profound effect on Michel de Montaigne, David Hume and Georg Wilhelm Friedrich Hegel, among many others. Another source for the circulation of Sextus's ideas was Pierre Bayle's ''Dictionary''. The legacy of Pyrrhonism is described in Richard Popkin's ''The History of Skepticism from Erasmus to Descartes'' and ''High Road to Pyrrhonism''. The transmission of Sextus's manuscripts through antiquity and the Middle Ages is reconstructed by Luciano Floridi's ''Sextus Empiricus, The Recovery and Transmission of Pyrrhonism'' (Oxford: Oxford University Press, 2002). Since the Renaissance French philosophy has been continuously influenced by Sextus: Michel de Montaigne, Montaigne in the 16th century, René Descartes, Descartes, Blaise Pascal, Pierre-Daniel Huet and François de La Mothe Le Vayer in the 17th century, many of the "Philosophes", and in recent times controversial figures such as Michel Onfray, in a direct line of filiation between Sextus' radical skepticism and secular or even radical atheism. Sextus is the earliest known source for the proverb "Slowly grinds the mill of the gods, but it grinds fine", alluded to in Henry Wadsworth Longfellow, Longfellow's poem "Retribution (poem), Retribution".D.L.
