No one can be great, or good, or happy except through the inward efforts of themselves.

Let a man begin in earnest with "I ought," and he will end, by God's grace, if he persevere, with "I will." Let him force himself to abound in all small offices of kindliness, attention, affectionateness, and all these for God's sake. By and by he will feel them become the habit of his soul.

I read hard, or not at all; never skimming, never turning aside to merely inciting books; and Plato, Aristotle, Butler, Thucydides, Sterne, Jonathan Edwards, have passed like the iron atoms of the blood into my mental constitution.

It is a law of our humanity, that man must know both good and evil; he must know good through evil. There never was a principle but what triumphed through much evil; no man ever progressed to greatness and goodness but through great mistakes.

The truest definition of evil is that which represents it as something contrary to nature; evil is evil because it is unnatural; a vine which should bear olive-berries, an eye to which blue seems yellow, would be diseased; an unnatural mother, an unnatural son, an unnatural act, are the strongest terms of condemnation.

A silent man is easily reputed wise. A man who suffers none to see him in the common jostle and undress of life, easily gathers round him a mysterious veil of unknown sanctity, and men honor him for a saint. The unknown is always wonderful.

Truth is given, not to be contemplated, but to be done. Life is an action, not a thought.
