A man is the sum of his ancestors; to reform him you must begin with a dead ape and work downward through a million graves. He is like the lower end of a suspended chain; you can sway him slightly to the right or the left, but remove your hand and he falls into line with the other links.
Ambrose Bierce
I have often thought that nothing would do more extensive good at small expense than the establishment of a small circulating library in every county, to consist of a few well-chosen books, to be lent to the people of the country under regulations as would secure their safe return in due time.
Thomas Jefferson
Whether we had a (good) moral intuition more developed, we would be as much morally disgusted by the rapacity of those who try to benefit from, and monopolize (or secure or corner), having no consideration (regardless or irrespective of) for others ("autrui", Fr.), than we physically are by a sickening (or nauseating) smell.
African Spir
I think that a good person can sometimes do wrong out of ignorance or weakness or wrong thinking, but when hard times come, the goodness wins out after all. And a bad person can often seem good and trustworthy for a long time, but when hard times come, the evil in him gets revealed.
