Reading is at the threshold of spiritual life; it can introduce us to it; it does not constitute it.

The soldier is convinced that a certain indefinitely extendable time period is accorded him before he is killed, the burglar before he is caught, men in general, before they must die. That is the amulet which preserves individuals — and sometimes populations — not from danger, but from the fear of danger, in reality from the belief in danger, which in some cases allows them to brave it without being brave. Such a confidence, just as unfounded, supports the lover who counts on a reconciliation, a letter.

A person does not...stand motionless and clear before our eyes with his merits, his defects, his plans, his intentions with regard to ourself exposed on his surface...but is a shadow which we can never succeed in penetrating...a shadow behind which we can alternately imagine, with equal justification, that there burns the flame of hatred and of love.
