Who said “Let a man turn to his own childhood -- no further -- if he will renew his sense of…”?

“That great Cathedral space which was childhood.”

“Childhood is the kingdom where nobody dies. Nobody that matters, that is.”

“I am convinced that, except in a few extraordinary cases, one form or another of an unhappy childhood is essential to the formation of exceptional gifts.”

“The childhood shows the man, as morning shows the day.”

“Childhood is a disease -- a sickness that you grow out of.”

“Happiness is not a matter of events; it depends upon the tides of the mind.”

“The sense of humor has other things to do than to make itself conspicuous in the act of laughter.”

“It is easy to replace man, and it will take no great time, where Nature has lapsed, to replace Nature.”

“If there is a look of human eyes that tells of perpetual loneliness, so there is also the familiar look that is the sign of perpetual crowds.”

“A child is beset with long traditions. And his infancy is so old, so old, that the mere adding of years in the life to follow will not seem to throw it back—it is already so far.”

“The true color of life is the color of the body, the color of the covered red, the implicit and not explicit red of the living heart and the pulses. It is the modest color of the unpublished blood.”
