"The aim of the Sceptic is ataraxia [freedom from mental perturbation or excitement] in matters which depend on opinion, and in things which are inevitable restraint of the feelings (_metriopatheian_). For he began to philosophise in order to judge his impressions (_phantasias_) and to discover which of them are true and which false, so as to be free from perturbation. But he came to a point where the arguments were at once diametrically opposite and of equal weight; and then, as he could not decide, he suspended judgment (_epeschen_), and as soon as he had done so, there followed as if by accident this very freedom from perturbation in the region of opinion. For if a man opines anything to be good or bad in its essential nature, he is always in perturbation. When he has not the things that appear to him to be good, he considers himself tortured by the things evil by nature, and he pursues the good (as he supposes them to be); but, as soon as he has them, he falls into even more perturbations, through being uplifted out of all reason and measure, and from fear of change he does everything not to lose the things that seem to him to be good. But the man, who makes no definitions as to what is good or bad by {217} nature, neither avoids nor pursues anything with eagerness, and is therefore unperturbed. What is related of Apelles the painter has in fact befallen the Sceptic. The story goes that he was painting a horse and wished to represent the foam of its mouth in his picture; but he was so unsuccessful that he gave it up, and took the sponge, on which he used to wipe the colours from his brush, and threw it at the picture. The sponge hit the picture and produced a likeness of the horse's foam. The Sceptics then hoped to gain ataraxia by forming some decision on the lack of correspondence between things as they appear to the eye and to the mind; they were unable to do it, and so suspended judgment (_epeschen_); and then as if by accident the ataraxia followed---just as a shadow follows a body. We do not say that the Sceptic is untroubled in every way, but we own he is troubled by things that are quite inevitable. For we admit that the Sceptic is cold sometimes, and thirsty, and so forth. But even in these matters the uneducated are caught in two ways at once, viz.: by the actual feelings and (not less) by supposing these conditions to be bad by nature. The Sceptic does away with the opinion that any one of these things is evil in its nature, and so he gets off more lightly even in these circumstances."[49] A view of this kind was hardly likely to appeal to the temper of the age, and the influence of Scepticism was practically none. Still it is interesting to find so vigorous and clear an exponent of the system flourishing in a period given over to the beliefs that Lucian parodied and Apuleius accepted. Sextus, it may be added, is the sole representative of ancient Scepticism whose works have come down to us in any complete form.
