" I was driven to reflect deeply and inveterately on that hard law of life, which lies at the root of religion and is one of the most plentiful springs of distress. Though so profound a double-dealer, I was in no sense a hypocrite; both sides of me were in dead earnest; I was no more myself when I laid aside restraint and plunged in shame, than when I laboured, in the eye of day, at the futherance of knowledge or the relief of sorrow and suffering. "
