The picture given of Pyrrho by Cicero is entirely different from that of Diogenes, and contrasts decidedly with it.[1] Cicero knows Pyrrho as a severe moralist, not as a Sceptic. Both authors attribute to Pyrrho the doctrine of indifference and apathy, but, according to Cicero, Pyrrho taught of virtue, honesty, and the summum bonum, while Diogenes plainly tells us that he considered nothing as good in itself, "and of all things nothing as true."[2] Cicero does not once allude to Pyrrhonean doubt. We see on the one hand, in Cicero's idea of Pyrrho, the influence of the Academy, perhaps even of Antiochus himself,[3] which probably colored the representations given of Pyrrho; but, on the other hand, there is much in Diogenes' account of Pyrrho's life and teachings, and in the writings of Timon, which shows us the positive side of Pyrrho. Pyrrho, in denying the possibility of all knowledge, made that rather a motive for indifference in the relations of life, than the foundation thought of a philosophical system. His teaching has a decided ethical side, showing in that respect the strong influence of Democritus over him, who, like Pyrrho, made happiness to consist in a state of feeling.[4] The one motive of all of Pyrrho's teaching is a positive one, the desire for happiness.

The essence of Pyrrhonism as given by Timon is as follows:[1] Man desires to be happy. To realise his desire he must consider three things:

(i)What is the nature of things?
(ii)How should man conduct himself in relation to them?
(iii)What is the result to him of this relation?

The nature of things is unknown. Our relation to them must be one of suspension of judgment, without activity, desire, or belief,—that is, an entirely negative relation. The result is that state of having no opinion, called ἐποχή, which is followed in turn by ἀταραξία.

[1] The problem of philosophy is here proposed very nearly in the terms of Kant, but not with the positive motive, like that of the great philosopher of Germany, of evolving a system to present the truth. Yet the importance of these questions shows the originality of Pyrrho. The earnestness of Pyrrho is further shown by an example given by Diogenes. Once on being found talking to himself alone, he said, when asked the reason, that he was meditating how to become a good man (χρηστός), [2] thus showing an entirely different spirit from anything found in Sextus' books. The explanation of his life and teachings is to be found largely in his own disposition. Such an attitude of indifference must belong to a placid nature, and cannot be entirely the result of a philosophical system, and, while it can be aimed at, it can never be perfectly imitated. One of his disciples recognised this, and said that it was necessary to have the disposition of Pyrrho in order to hold his doctrines.[3] Diogenes tells us that he was the first to advance any formulae of Scepticism,[4] but they must have been very elementary, as Pyrrho himself wrote nothing. We find no trace of formulated Tropes in Pyrrho's teachings, yet it is probable that he indicated some of the contradictions in sensation, and possibly the Tropes in some rudimentary form. Of the large number of sceptical formulae, or φωναί, the three which seem to have the oldest connection with Scepticism are the ἀντιλογία, the οὐδὲν ὁρίζω, and the οὐ μᾶλλον. [5] We know from Diogenes that Protagoras is the authority for saying that in regard to everything there are two opposing arguments.[6] The saying "to determine nothing" is quoted from Timon's Python by Diogenes,[7] and the other two mentioned are also attributed to him by Aristocles.[8] We have also in the οὐ μᾶλλον a direct connection with Democritus, although the difference in the meaning which he attributed to it is shown by Sextus.[9] So while the expression is the same, the explanation of it given by Pyrrho must have been different. It would seem probable that Pyrrho used all of these three sayings, from the account of Diogenes, and that even then they gave rise to the accusation of the Dogmatics, that simply by possessing such sayings the Sceptics dogmatised,[10] for the refutation of this used by Sextus occurs in the old account of the sayings, namely, that these formulae include also themselves in the meaning, as a cathartic removes itself together with other harmful objects.[11]
