Context: Why should man be afraid to think, and why should he fear to express his thoughts?
Is it possible that an infinite Deity is unwilling that a man should investigate the phenomena by which he is surrounded? Is it possible that a god delights in threatening and terrifying men? What glory, what honor and renown a god must win on such a field! The ocean raving at a drop; a star envious of a candle; the sun jealous of a fire-fly.
