The same reality pervades all teaching. The man may teach by doing, and not otherwise. If he can communicate himself he can teach, but not by words. He teaches who gives, and he learns who receives. There is no teaching until the pupil is brought into the same state or principle in which you are; a transfusion takes place; he is you and you are he; then is a teaching, and by no unfriendly chance or bad company can he ever quite lose the benefit. But your propositions run out of one ear as they ran in at the other. We see it advertised that Mr. Grand will deliver an oration on the Fourth of July, and Mr. Hand before the Mechanics’ Association, and we do not go thither, because we know that these gentlemen will not communicate their own character and experience to the company. If we had reason to expect such a confidence we should go through all inconvenience and opposition. The sick would be carried in litters. But a public oration is an escapade, a non-committal, an apology, a gag, and not a communication, not a speech, not a man. A like Nemesis presides over all intellectual works. We have yet to learn that the thing uttered in words is not therefore affirmed. It must affirm itself, or no forms of logic or of oath can give it evidence. The sentence must also contain its own apology for being spoken. The effect of any writing on the public mind is mathematically measurable by its depth of thought. How much water does it draw? If it awaken you to think, if it lift you from your feet with the great voice of eloquence, then the effect is to be wide, slow, permanent, over the minds of men; if the pages instruct you not, they will die like flies in the hour. The way to speak and write what shall not go out of fashion is to speak and write sincerely. The argument which has not power to reach my own practice, I may well doubt will fail to reach yours. But take Sidney’s maxim:—“Look in thy heart, and write.” He that writes to himself writes to an eternal public. That statement only is fit to be made public which you have come at in attempting to satisfy your own curiosity. The writer who takes his subject from his ear and not from his heart, should know that he has lost as much as he seems to have gained, and when the empty book has gathered all its praise, and half the people say, ‘What poetry! what genius!’ it still needs fuel to make fire. That only profits which is profitable. Life alone can impart life; and though we should burst we can only be valued as we make ourselves valuable. There is no luck in literary reputation. They who make up the final verdict upon every book are not the partial and noisy readers of the hour when it appears, but a court as of angels, a public not to be bribed, not to be entreated and not to be overawed, decides upon every man’s title to fame. Only those books come down which deserve to last. Gilt edges, vellum and morocco, and presentation-copies to all the libraries will not preserve a book in
