Philippus Theophrastus Aureolus Bombastus von Hohenheim, also known as Paracelsus (1493-1541) – philosopher, alchemist, doctor, traveler, teller of fantastic stories, and flaneur extraordinaire:
Life is like music, it must be composed by ear, feeling and instinct, not by rule. Nevertheless one had better know the rules, for they sometimes guide in doubtful cases, though not often.
