Old paint on canvas, as it ages, sometimes becomes transparent. When that happens it is possible, in some pictures, to see the original lines: a tree will show through a woman's dress, a child makes way for a dog, a large boat is no longer on an open sea. That is called pentimento because the painter 'repented,' changed his mind. Perhaps it would be as well to say that the old conception, replaced by a later choice, is a way of seeing and then seeing again.

The human being is always more than what he has done; he is also what he can do.

Emotions can capture attention automatically, demonstrating the close link between affective and cognitive systems.

The great epochs of our life are the occasions when we gain the courage to rebaptize our badness as the best in us.

你不必伟大才能开始，但你必须开始才能伟大。
