“In fact, you could say that what orients a person to the bittersweet is a heightened awareness of finality.”

In Search of Memory (2006)
Context: By merely observing the electrical activity in the brain, Libet could predict what a person would do before the person was actually aware of having decided to do it. This finding caused philosophers of mind to ask: If the choice is determined in the brain before we decide to act, where is free will?... choice in action, as in perception, may reflect the importance of unconscious inference. Libet proposes that... just before the action is initiated, consciousness is recruited to approve or veto the action.

Context: The role of the writer is not to say what we can all say, but what we are unable to say. Most of the writing today which is called fiction contains such a poverty of language, such triteness, that it is a shrunken, diminished world we enter, poorer and more formless than the poorest cripple deprived of ears and eyes and tongue. The writer's responsibility is to increase, develop our senses, expand our vision, heighten our awareness and enrich our articulateness.

Context: I feel, like all modern Americans, no consciousness of sin and simply do not believe in it. All I know is that if God loves me only half as much as my mother does, he will not send me to Hell. That is a final fact of my inner consciousness, and for no religion could I deny its truth.
