A man s growth is seen in the successive choirs of his friends.

In some ways, spiritual growth resembles a game of leapfrog. As soon as we've got past one puzzling question, we discover we're faced with another.

The most important influence on a child is the character of its parents, rather than this or that single event.

Man always dies before he is fully born.

Man, the most complicated of the animals, has a relatively short gestation period. Beyond that, he will be born, unlike most mammals, in a ridiculously helpless state.

A road that does not lead to other roads always has to be retraced, unless the traveller chooses to rust at the end of it.

A child-like man is not a man whose development has been arrested; on the contrary, he is a man who has given himself a chance of continuing to develop long after most adults have muffled themselves in the cocoon of middle-aged habit and convention.

Just as we outgrow a pair of trousers, we outgrow acquaintances, libraries, principles, etc., at times before they're worn out and at times-and this is the worst of all-before we have new ones.

All growth is a leap in the dark, a spontaneous, unpremeditated act without benefit of experience.

Growth is the only evidence of life.
