Sexual pleasure, wisely used and not abused, may prove the stimulus and liberator of our finest and most exalted activities.

The mathematician has reached the highest rung on the ladder of human thought.

The art of dancing stands at the source of all the arts that express themselves first in the human person. The art of building, or architecture, is the beginning of all the arts that lie outside the person; and in the end they unite.

Failing to find in women exactly the same kind of sexual emotions, as they find in themselves, men have concluded that there are none there at all.

The husband - by primitive instinct partly, certainly by ancient tradition - regards himself as the active partner in matters of love and his own pleasure as legitimately the prime motive for activity.

One can know nothing of giving aught that is worthy to give unless one also knows how to take.
