"Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a god; because, if there be one, he must approve the homage of reason rather than of blind-folded fear. Do not be frightened from this inquiry by any fear of its consequences.... If it end in a belief that there is no god, you will find incitements to virtue in the comfort and pleasantness you feel in its exercise and in the love of others it will procure for you."
