Reckoned physiologically, everything ugly weakens and afflicts man. It recalls decay, danger, impotence; he actually suffers a loss of energy in its presence.

His feeling of power, his will to power, his courage, his pride - they decline with the ugly, they increase with the beautiful.

All credibility, all good conscience, all evidence of truth come only from the senses.
