"I hate books; they only teach us to talk about things we know nothing about. Hermes, they say, engraved the elements of science on pillars lest a deluge should destroy them. Had he imprinted them on men's hearts they would have been preserved by tradition. Well-trained minds are the pillars on which human knowledge is most deeply engraved. Since we must have books, there is one book which, to my thinking, supplies the best treatise on an education according to nature. This is the first book Emile will read; for a long time it will form his whole library, and it will always retain an honoured place. It will be the text to which all our talks about natural science are but the commentary. It will serve to test our progress towards a right judgment, and it will always be read with delight, so long as our taste is unspoilt. What is this wonderful book? Is it Aristotle? Pliny? Buffon? No; it is Robinson Crusoe. Robinson Crusoe on his island, deprived of the help of his fellow-men, without the means of carrying on the various arts, yet finding food, preserving his life, and procuring a certain amount of comfort; this is the thing to interest people of all ages, and it can be made attractive to children in all sorts of ways. We shall thus make a reality of that desert island which formerly served as an illustration. The condition, I confess, is not that of a social being, nor is it in all probability Emile's own condition, but he should use it as a standard of comparison for all other conditions. The surest way to raise him above prejudice and to base his judgments on the true relations of things, is to put him in the place of a solitary man, and to judge all things as they would be judged by such a man in relation to their own utility."
