My son, there is no happiness without courage, nor virtue without a struggle. The word virtue is derived from a word signifying strength, and strength is the foundation of all virtue. Virtue is the heritage of a creature weak by nature but strong by will; that is the whole merit of the righteous man; and though we call God good we do not call Him virtuous, because He does good without effort. I waited to explain the meaning of this word, so often profaned, until you were ready to understand me. As long as virtue is quite easy to practise, there is little need to know it. This need arises with the awakening of the passions; your time has come. "When I brought you up in all the simplicity of nature, instead of preaching disagreeable duties, I secured for you immunity from the vices which make such duties disagreeable; I made lying not so much hateful as unnecessary in your sight; I taught you not so much to give others their due, as to care little about your own rights; I made you kindly rather than virtuous. But the kindly man is only kind so long as he finds it pleasant; kindness falls to pieces at the shook of human passions; the kindly man is only kind to himself.

for nature delivers us from the evils she lays upon us, or else she teaches us to submit to them; but she has no message for us with regard to our self-imposed evils; she leaves us to ourselves; she leaves us, victims of our own passions, to succumb to our vain sorrows, to pride ourselves on the tears of which we should be ashamed.
