There are few people able to realise what an effect such reading, carefully directed, will have upon the unspoilt mind of a youth. Weighed down by books from our earliest childhood, accustomed to read without thinking, what we read strikes us even less, because we already bear in ourselves the passions and prejudices with which history and the lives of men are filled; all that they do strikes us as only natural, for we ourselves are unnatural and we judge others by ourselves. But imagine my Emile, who has been carefully guarded for eighteen years with the sole object of preserving a right judgment and a healthy heart, imagine him when the curtain goes up casting his eyes for the first time upon the world’s stage; or rather picture him behind the scenes watching the actors don their costumes, and counting the cords and pulleys which deceive with their feigned shows the eyes of the spectators. His first surprise will soon give place to feelings of shame and scorn of his fellow-man; he will be indignant at the sight of the whole human race deceiving itself and stooping to this childish folly; he will grieve to see his brothers tearing each other limb from limb for a mere dream, and transforming themselves into wild beasts because they could not be content to be men.
Given the natural disposition of the pupil, there is no doubt that if the master exercises any sort of prudence or discretion in his choice of reading, however little he may put him in the way of reflecting on the subject-matter, this exercise will serve as a course in practical philosophy, a philosophy better understood and more thoroughly mastered than all the empty speculations with which the brains of lads are muddled in our schools. After following the romantic schemes of Pyrrhus, Cineas asks him what real good he would gain by the conquest of the world, which he can never enjoy without such great sufferings; this only arouses in us a passing interest as a smart saying; but Emile will think it a very wise thought, one which had already occurred to himself, and one which he will never forget, because there is no hostile prejudice in his mind to prevent it sinking in. When he reads more of the life of this madman, he will find that all his great plans resulted in his death at the hands of a woman, and instead of admiring this pinchbeck heroism, what will he see in the exploits of this great captain and the schemes of this great statesman but so many steps towards that unlucky tile which was to bring life and schemes alike to a shameful death?
