The active part of man consists of powerful instincts, some of which are gentle and continuous; others violent and short; some baser, some nobler, and all necessary. – Francis W. Newman
If men as individuals surrender to the call of their elementary instincts, avoiding pain and seeking satisfaction only for their own selves, the result for them all taken together must be a state of insecurity, of fear, and of promiscuous misery. – Albert Einstein
The repose of sleep refreshes only the body. It rarely sets the soul at rest. The repose of the night does not belong to us. It is not the possession of our being. Sleep opens within us an inn for phantoms. In the morning we must sweep out the shadows. – Gaston Bachelard
