I think we must assume it as the judgment of common sense that there neither is nor is likely to be any educational mortar wherein a fool may be so brayed that he shall come forth a wise man. The broad, unequivocal sentence of history seems to be that whoever is not noble by nature will hardly be rendered so by art. Education can do much; it can foster nobilities, it can discourage vices; but literal conveyance of lofty qualities, can it effect that? Can it create opulence of soul in a sterile nature? Can it cause a thin soil to do the work of a deep one? We have seen harsh natures mellowed, violent natures chastened, rough ones refined; but who has seen an essentially mean nature made large-hearted, self-forgetful, fertile of grandest faiths and greatest deeds? Who has beheld a Thersites transformed into an Achilles? Who a Shylock, Iago, or Regan changed into an Antonio, Othello, or Cordelia, or a Simon Magus into a Paul? What virtue of nature is in a man culture may bring out; but to put nature into any man surpasses her competence. Nay, it would even seem that in some cases the finest openings and invitations for what is best in man must operate inversely, and elicit only what is worst in him. Every profoundest truth, when uttered with fresh power in history, polarizes men, accumulating atheism at one pole, while collecting faith and resolve at the other. As the sun bleaches some surfaces into whiteness, but tans and blackens others, so the sweet shining of Truth illumines some countenances with belief, but some it darkens into a scowl of hate and denial. The American Revolution gave us George Washington; but it gave us also Benedict Arnold. One and the same great spiritual emergency in Europe produced Luther's Protestantism and Loyola's Jesuitism. Our national crisis has converted General Butler; what has it done for Vallandigham? It were easy to show that the deepest intelligence of the world concurs with common sense in this judgment. Its declaration ever is, in effect, that, though Paul plant and Apollos water, yet fruit can come only out of divine and infinite Nature,--only, that is, out of the native, incommunicable resources of the soul. "No man can come to me," said Jesus, "except the Father draw him." "To him that hath shall be given." The frequent formula, "He that hath ears to hear, let him hear," is a confession that no power of speech, no wisdom of instruction, can command results. The grandest teacher, like the humblest, can but utter his word, sure that the wealthy and prepared spirits will receive it, and equally sure that shallow, sterile, and inane natures will either not receive it at all, or do so to extremely little purpose.
