Rousseau was fifty when he wrote the book, and it followed closely on his Social Contract and New Heloïsa, that is to say, he was able to envisage his childhood, boyhood, and youth across the corrective experience of the years that for most men kill out the early illusions and only spare the ideals that can stand the wear and tear of reality. In his Confessions he reveals enough of his overwrought sensibility, his tears, his passions très-ardentes, his effervescences de sang, to let us enlarge the picture he gives in Emile. We see him there an abnormally sensitive creature, a child that is both more and less of a child than the average. But this very excess has its advantage. The emotions, the love of beauty and desire for happiness, the sense of pain and fear, the vanity, the self-consciousness, being all carried to their extreme, are more certain of being brought to the sharper test. The risks they incur, the faculties they accompany and serve to hide, the pliant yet steadfast supports they need in the growth to maturity, are only to be understood and pointed out by one who, like the little Genevan boy, has felt their effect for good and evil in his own person.
