Grasshopper: So why engage in philosophy at all and thus how do we know about a “school” of Greek thought called skepticism?

Master Pretense: Well, we have Sextus Empiricus and the Diogenes I mentioned earlier to thank for our knowing about Pyrrho. As Suber mentioned, skepticism has a formal relationship to Stoicism and has a similar vocabulary to Epicurean philosophy. Still let’s go to the Stanford Encyclopedia of Philosophy for the context:

Skeptical doubts are said to characterize times of social upheaval (a connection said to characterize, not only the ancient world, but the fourteenth century and our own era). It is difficult to judge such general claims, but it would be surprising if the foundational doubts that characterize skepticism were not more evident in times when social and intellectual turmoil invite deep questions about what is right and wrong and true and false.

Ancient skepticism’s ties to other trends in ancient philosophy are more easily observed. They are particularly evident in the considerations that motivate the skeptics’ decision to suspend judgment on the truth of any claim. The skeptics’ conclusion that truth is uncertain is at odds with the “dogmatic” philosophies they reject, but this conclusion may still be founded on a similar focus on opposing arguments, antithesis, and conflicting points of view. One might, for example, easily compare the Pyrrhonian conviction that there are equally convincing arguments for and against any claim to the Protagorean view that one can argue equally convincingly on both sides of any question. In both cases, one finds a general commitment to the possibility of convincing arguments for opposing points of view. Despite this mutual commitment, Protagoras defended a perspective which is in some ways diametrically opposed to skepticism (at least if we judge by Plato’s account of Protagoras in his Theaetetus), for it accepts rather than rejects opposing claims to truth.

Ancient skepticism has many affinities to other ancient philosophies. Greek atomism shares, for example, skepticism’s interest in opposing perceptions and points of view, and can be seen as an attempt to explain this opposition by hypothesizing atoms which impact on different kinds of bodies (the bodies of different individuals, and of different species) in different kinds of ways. Opposites which include opposing points of view also played a central role in Heracleitean and Platonic epistemology. Even Aristotelean philosophy has affinities to skepticism, affinities which are in this case manifest in an Aristotelean rhetorical tradition which incorporates the rhetorical works of Theophrastus, Demetrius of Phalerum and others, and which emphasizes the power of persuasive speech rather than argument’s ability to establish what is true.

In a number of cases, philosophers who have no direct ties to the skeptical schools anticipate skepticism by stressing the difficulties inherent in inquiry. Xenophanes was known for his claim that no one knows clear truth; Democritus maintained that “bastard” knowledge gained through the senses exists only by convention; Plato’s dialogues contained arguments pro and contra, and cast doubt on everyday opinions; Diogenes of Sinope and other Cynics dismiss philosophical speculation; Epictetus insists that philosophers spend too much time on theory (En., 51); and so on. The philosophies that such philosophers endorsed do not incorporate a full fledged skepticism, but their influence added impetus to the skeptics’ moves in this direction.

More generally, ancient skepticism flourished in an intellectual milieu which incorporated many general themes and trends conducive to skeptical conclusions. In marked contrast with modern science, ancient science could not boast the practical and theoretical successes of its modern counterpart. In part because of this, mysticism and irrationalism were powerful cultural forces in the ancient world. The possibility of conflicting views of things was reinforced by an interest in foreign cultures which drew attention to opposing customs and traditions. Opposing interests and perspectives were also manifest in debate, war, political rivalries and a religion and mythology which pitted god against god, man against man and even god against man.

Within this broader context, ancient philosophical inquiry is characterized both by a remarkable array of conflicting philosophical perspectives and by famous philosophers known for dazzling arguments for paradoxical conclusions (that motion is impossible, that nothing exists, that time is an illusion, etc.). In the midst of the conflicting views and conclusions that this implies, it is not surprising that some philosophers propound the conclusion that reason cannot establish truth, and gives us no way to choose between opposing arguments and opposing points of view.

Grasshopper: That’s one hell of a quote block.

Master Pretense: Don’t go meta-dialogue on me. We’re breaking the fourth wall.

Grasshopper: There is no wall. The readers are looking at screen.

Master Pretense: Metaphors, young grasshopper, are a dish best served mixed.

Grasshopper: You didn’t answer my question about why engage in philosophy if you believed like Pyrrho

Master Pretense: How would I know? I am just your teacher, not a dead Greek philosopher. Ask Pyrrho.

Grasshopper: You can’t pull another one of those quote thingies to explain?

Master Pretense: Fine. I’ll go to Wikipedia:

The goal of this critique, which Pyrrho’s followers realized would ultimately subvert even their own method, was to cultivate a distrust of all grand talk. They expected philosophy to collapse into itself. How far in this direction the Pyrrhonean commitment extended is a matter of debate. The Pyrrhonists confessed a belief in appearances, e.g. in hot and cold, grief and joy. It is impossible to deny, they admitted, that one seems to be in pain or seems to touch a piece of wood. Their world, thus, was completely phenomenological. An accomplished Pyrrhonist could, ideally, live as well as a dogmatist but with the added benefit of not worrying about truth and falsity, right and wrong, God’s will, and so forth.

So yes, the original Pyrrho knew that this could be caustic to philosophy.

Grasshopper: So what did Pyrrho believe again?

Master Pretense: The only real good evidence we have for Pyrrho’s beliefs can be found in a fragment from the philosophy Aristocles

He [Pyrrho] himself has left nothing in writing, but this pupil Timon says that whoever wants to be happy must consider these three questions: first, how are things by nature? Secondly, what attitude should we adopt towards them? Thirdly, what will be the outcome for those who have such an attitude? According to Timon, Pyrrho declared that things are equally indifferent, unmeasurable and inarbitrable. For this reason neither our sensations nor our opinions tell us truths or falsehoods. Therefore for this reason we should not put our trust in them one bit, but should be unopinionated, uncommitted and unwavering, saying concerning each individual thing that it no more is than is not, or both is and is not, or neither is nor is not. The outcome for those who actually adopt this attitude, says Timon, will be first speechlessness [aphasia], and then freedom from disturbance; and Aenesidemus says pleasure. (Eusebius, Prep. Ev. 14.18.2–5, Long & Sedley)

The Stanford Encyclopedia explains,

The interpretation of this passage is the subject of debate (see Bett, Pyrrho). According to the interpretation most in keeping with later skepticism, Pyrrho holds that things appear with equal force to be and not to be (and to both be and not to be; and to neither be nor not to be). According to an alternative (“metaphysical”) interpretation, Pyrrho holds that this is how things actually are — i.e. that things in the world actually are and are not (and both are and are not, and neither are nor are not). If the latter interpretation is correct, it is a historical irony that Pyrrho became the most famous spokesperson for a later skepticism which rejects all claims about the true nature of the world.

If the second view is true, Pyrrho would have agreed with the Buddhist thinker Nagarjuna. Suber, however, thinks that even if the first view is true, Pyrrho would have concerned with something other than “doubt” in the strict sense:

The dogmatist asserts that something is true. He makes judgments he is willing to stand by. The skeptic suspends her judgment; she waits until she is sure, which may be never. Suspension of judgment (in Greek, epoche), not doubt and not denial, is the skeptic’s characteristic activity. This is the next important technical term. The Greek word epoche means to check, cease, suspend, stop, or pause in some activity that otherwise or normally occurs. The skeptics applied the word to judgment, while in other contexts Greek speakers applied it to sunlight (in eclipses), menstruation (in pregnancy), payments on a debt (in default), musical vibrations of a string (at the nodes), and the passage of time (at turning points or “epochs”). The English phrase “suspension of judgment” captures the gist of the skeptical usage well, but loses the flavor of a versatile common word doing philosophical work. If we had to coin a word to capture more of its sense, “ajudice” (meaning non-judgment, on the model of “prejudice”, meaning pre-judgment) might work well.

Grasshopper: Wait. You need to back track and explain to me how this relevant to say Carl Sagan or James Randi or Bob the Village Atheist or Eric the Objectivist who doesn’t believe in global warming.

Master Pretense: All in good time, Grasshopper.
