Human life occurs only once, and the reason we cannot determine which of our decisions are good and which bad is that in a given situation we can make only one decision; we are not granted a second, third, or fourth life in which to compare various decisions.

From tender youth we are told by father and teacher that betrayal is the most heinous offence imaginable. But what is betrayal?…Betrayal means breaking ranks and breaking off into the unknown. Sabina knew of nothing more magnificent than going off into the unknown.

Only the most naive of questions are truly serious.

The heaviest of burdens is simultaneously an image of life's most intense fullfillment. The heavier the burden, the closer our lives come to the earth, the more real and truthful they become. Conversely, the absolute absence of a burden causes man to be lighter than air, to soar into new heights, take leave of the earth and his earthly being, and become only half real, his movements as free as they are insignificant. What then shall we choose? Weight or lightness?

This was exactly what the girl had most dreaded all her life and had scrupulously avoided until now: lovemaking without emotion or love. She knew that she had crossed the forbidden boundary, but she proceeded across it without objections and as a full participant; only somewhere, far off in a corner of her consciousness, did she feel horror at the thought that she had never known such pleasure, never so much pleasure as at this moment--beyond that boundary.

Necessity, weight, and value are three concepts inextricably bound: only necessity is heavy, and only what is heavy has value.

Suspending moral judgment is not the immorality of the novel; it is its morality.
