The notion that faith in Christ is to be rewarded by an eternity of bliss, while a dependence upon reason, observation, and experience merits everlasting pain, is too absurd for refutation, and can be believed only by that unhappy mixture of insanity and ignorance, called faith.

The man who invented the telescope found out more about heaven than the closed eyes of prayer ever discovered.
