If I wanted to teach rhetoric to a youth whose passions were as yet undeveloped, I would draw his attention continually to things that would stir his passions, and I would discuss with him how he should talk to people so as to get them to regard his wishes favourably. But Emile is not in a condition so favourable to the art of oratory. Concerned mainly with his physical well-being, he has less need of others than they of him; and having nothing to ask of others on his own account, what he wants to persuade them to do does not affect him sufficiently to awake any very strong feeling. From this it follows that his language will be on the whole simple and literal. He usually speaks to the point and only to make himself understood. He is not sententious, for he has not learnt to generalise; he does not speak in figures, for he is rarely impassioned. Yet this is not because he is altogether cold and phlegmatic, neither his age, his character, nor his tastes permit of this. In the fire of adolescence the life-giving spirits, retained in the blood and distilled again and again, inspire his young heart with a warmth which glows in his eye, a warmth which is felt in his words and perceived in his actions. The lofty feeling with which he is inspired gives him strength and nobility; imbued with tender love for mankind his words betray the thoughts of his heart; I know not how it is, but there is more charm in his open-hearted generosity than in the artificial eloquence of others; or rather this eloquence of his is the only true eloquence, for he has only to show what he feels to make others share his feelings. The more I think of it the more convinced I am that by thus translating our kindly impulses into action, by drawing from our good or ill success conclusions as to their cause, we shall find that there is little useful knowledge that cannot be imparted to a youth; and that together with such true learning as may be got at college he will learn a science of more importance than all the rest together, the application of what he has learned to the purposes of life. Taking such an interest in his fellow-creatures, it is impossible that he should fail to learn very quickly how to note and weigh their actions, their tastes, their pleasures, and to estimate generally at their true value what may increase or diminish the happiness of men; he should do this better than those who care for nobody and never do anything for any one. The feelings of those who are always occupied with their own concerns are too keenly affected for them to judge wisely of things. They consider everything as it affects themselves, they form their ideas of good and ill solely on their own experience, their minds are filled with all sorts of absurd prejudices, and anything which affects their own advantage ever so little, seems an upheaval of the universe.
