Let us imagine the moral effect on the minds of the ablest youth of Greece of such an absolute collapse of belief. The philosophic scepticism did not deprive them of their appetites or passions; it did not in the least alter their estimate of the prizes of success, or the desirability of wealth and power. All it did was to shatter the invisible social bonds of reverence and honour and truth and justice, which in greater or less degree act as a restraining force upon the purely selfish appetites of men. Not only belief in divine government disappeared, but belief in any government external or internal; justice became a cheating device to deprive a man of what was ready to his grasp; good-faith was stupidity when it was not a more subtle form of deceit; morality was at best a mere convention which a man might cancel if {96} he pleased; the one reality was the appetite of the moment, the one thing needful its gratification; society, therefore, was universal war, only with subtler weapons. Of course Protagoras and Gorgias were only notable types of a whole horde of able men who in various ways, and with probably less clear notions than these men of the drift or philosophic significance of their activity, helped all over Greece in the promulgation of this new gospel of self-interest. Many Sophists no doubt troubled themselves very little with philosophical questions; they were 'agnostics,' know-nothings; all they professed to do was to teach some practical skill of a verbal or rhetorical character. They had nothing to do with the nature or value of ideals; they did not profess to say whether any end or aim was in itself good or bad, but given an end or aim, they were prepared to help those who hired them to acquire a skill which would be useful towards attaining it.
