"A facility for quotation hides an absence of original thought."

"I feel no need for any other faith than my faith in the kindness of human beings. I am so absorbed in the wonder of earth and the life upon it that I cannot think of heaven and angels." -Pearl S. Buck

Yes, I'm pretty much a humanist, why do you ask? Day to day, though, this fits better:

"I don't spend much time thinking about whether God exists. I don't consider that a relevant question. It's unanswerable and irrelevant to my life, so I put it in the category of things I can't worry about." - Wendy Kaminer

I know you guys'd get worried if I started coming up with too many serious quotations, so I end with Chesterton:

"I always like a dog so long as he isn't spelled backward."

The subject quote is from Dorothy Sayer's Lord Peter Wimsey.
