Man was nature's mistake -she neglected to finish him - and she has never ceased paying for her mistake.

Call not that man wretched, who whatever ills he suffers, has a child to love.

The misery of a child is interesting to a mother, the misery of a young man is interesting to a young woman, the misery of an old man is interesting to nobody.

It still holds true that man is most uniquely human when he turns obstacles into opportunities

Whenever you trace the origin of a skill or practices which played a crucial role in the ascent of man, we usually reach the realm of play.

It is futile to judge a kind deed by its motives. Kindness can become its own motive. We are made kind by being kind.
