Now, speaking generally, the essential nature of Scepticism consists in its considering that to self-consciousness on its own account, there proceeds from the disappearance of all that is objective, all that is held to be true, existent or universal, all that is definite, all that is affirmative, through the withholding of assent, the immovability and security of mind, this imperturbability in itself. Hence the same result is obtained, that we have already seen in systems of philosophy immediately preceding this. Thus as soon as anything is held to be truth to self-consciousness, we find the result that to self-consciousness this truth is the universal reality, passing beyond itself, and in regard to this, self-consciousness esteems itself as nothing. But this external and determinate truth, as finite, is not implicitly existent, so that its necessity is to vacillate and give way. Then when this security disappears, self-consciousness itself loses its equilibrium, and becomes driven hither and thither in unrest, fear and anguish; for its stability and rest is the permanence of its existence and truth. But sceptical self-consciousness is just this subjective liberation from all the truth of objective Being, and from the placing of its existence in anything of the kind; Scepticism thus makes its end the doing away with the unconscious servitude in which the natural self-consciousness is confined, the returning into its simplicity, and, in so far as thought establishes itself in a content, the curing it of having a content such as this established in thought. “The effective principle of Scepticism,” Sextus hence tells us (Pyrrh. Hyp. I. c. 6, § 12, c. 12, §§ 25-30), “is the hope of attaining to security. Men of distinguished excellence, disquieted through the instability of things, and dubious as to which should in preference be given assent to, began the investigation of what is the truth and what false in things, as if they could reach imperturbability through the decision of such matters. But while engaged in this investigation, man attains the knowledge that opposite determinations,” desires, customs, &c., “have equal power,” and thus resolve themselves; “since in this way he cannot decide between them, he really only then attains to imperturbability when he withholds his judgment. For if he holds anything to be good or evil by nature, he never is at rest, whether it be that he does not possess what he holds to be good, or that he thinks himself vexed and assailed by natural evil. But he who is undecided respecting that which is good and beautiful in nature, neither shuns nor seeks anything with zeal; and thus he remains unmoved. What happened to the painter Apelles, befalls the Sceptic. For it is told that when he was painting a horse, and was altogether unsuccessful in rendering the foam, he finally in anger threw the sponge on which he had wiped his brushes, and in which every colour was therefore mixed,
