But though, according to this, Scepticism always expresses itself as if everything were in appearance only, the Sceptics go further than those who support the newer and purely formal idealism. For they deal with content, and demonstrate of all content that it is either experienced by the senses or thought, and consequently that it has something in opposition to it. Thus they show in the same thing the contradiction that exists, so that of everything that is presented the opposite also holds good. This is the objective element in Scepticism in its manifestation, and that through which it is not subjective idealism. Sextus (Pyrrh. Hyp. I. c. 13, §§ 32, 33) says: “Thus, for instance, the sensuous is set against the sensuous by our being reminded of the fact that the same tower when looked at near is square and when regarded in the distance looks round;” and hence the one assertion is as good as the other. This, indeed, is a very trivial example, but its interest lies in the thought that is present in it. “Or what is thought is set in opposition to what is thought. As to the fact that there is a providence,” which rewards the good and punishes the evil, “men appeal,” as against those who deny it, “to the system of the heavenly bodies; to this it is objected that the good often fare badly and the evil well, from which we demonstrate that there is no providence.” As to the “opposition of what is thought to the sensuous,” Sextus adduces the conclusion of Anaxagoras, who asserts of the snow, that although it appears to be white, regarded in relation to the reasons given by reflection it is black. For it is frozen water, but water has no colour and hence is black; consequently snow must be the same.
