A lifetime is not too long to spend in learning about the world.

Childhood’s work is learning, and it is in his play...that the child works at his job.

The most important phase of a child’s life was the beginning of it. He must be started right.

A school’s job [is] to begin education.

The child, unhampered, does not waste time.

Children do not grow up all of a piece; look for the child of seven, especially to take many backward glances at the way he has come, while bounds and leaps unevenly ahead in his growth.

It is only in retrospect that the high points of our lives rise up, flaunting banners.
