work was a protest.  We need not complain very loudly that while remonstrating against the restless intrepidity of the rationalists of his generation, he passed over the central truth, namely that the full and ever festal life is found in active freedom of curiosity and search taking significance, motive, force, from a warm inner pulse of human love and sympathy.  It was not given to Rousseau to see all this, but it was given to him to see the side of it for which the most powerful of the men living with him had no eyes, and the first Discourse was only a moderately successful attempt to bring his vision before Europe.  It was said at the time that he did not believe a word of what he had written.[172] It is a natural characteristic of an age passionately occupied with its own set of ideas, to question either the sincerity or the sanity of anybody who declares its sovereign conceptions to be no better than foolishness.  We cannot entertain such a suspicion.  Perhaps the vehemence of controversy carries him rather further than he quite meant to go, when he declares that if he were a chief of an African tribe, he would erect on his frontier a gallows, on which he would hang without mercy the first European who should venture to pass into his territory, and the first native who should dare to pass out of it.[173] And there are many other extravagances of illustration, but the main position is serious enough, as represented in the emblematic vignette with which the essay was printed—­the torch of science brought to men by Prometheus, who warns a satyr that it burns; the satyr, seeing fire for the first time and being fain to embrace it, is the symbol of the vulgar men who, seduced by the glitter of literature, insist on delivering themselves up to its study.[174] Rousseau’s whole doctrine hangs compactly together, and we may see the signs of its growth after leaving his hands in the crude formula of the first Discourse, if we proceed to the more audacious paradox of the second.

II.

The Discourse on the Origin of Inequality among men opens with a description of the natural state of man, which occupies considerably more than half of the entire performance.  It is composed in a vein which is only too familiar to the student of the literature of the time, picturing each habit and thought, and each step to new habits and thoughts, with the minuteness, the fulness, the precision, of one who narrates circumstances of which he has all his life been the close eye-witness.  The natural man reveals to us every motive, every process internal and external, every slightest circumstance of his daily life, and each element that gradually transformed him into the non-natural man.  One who had watched bees or beetles for years could not give us a more full or confident account of their doings, their hourly goings in and out, than it was the fashion in the eighteenth century to give of the walk and conversation of the primeval ancestor.  The conditions of primitive man were discussed by very incompetent ladies and gentlemen at convivial supper parties, and settled with complete assurance.[175]
