Morality is character and conduct such as is required by the circle or community in which the mans life happens to be placed. It shows how much good men require of us. – Henry Ward Beecher

Moral excellence comes about as a result of habit. We become just by doing just acts, temperate by doing temperate acts, brave by doing brave acts. – Aristotle

While moral rules may be propounded by authority the fact that these were so propounded would not validate them. – Sir Alfred Jules Ayer
