[Do you worry unnecessarily about the future? Remember most fears are just False Evidence Appearing Real. Don't let unfounded fears rob you of the joys of life or you too will say...] There has been much tragedy in my life; [and] at least half of it actually happened.

The so-called Christian nations are the most enlightened and progressive ... but in spite of their religion, not because of it. The Church has opposed every innovation and discovery from the day of Galileo down to our own time, when the use of anesthetic in childbirth was regarded as a sin because it avoided the biblical curse pronounced against Eve. And every step in astronomy and geology ever taken has been opposed by bigotry and superstition. The Greeks surpassed us in artistic culture and in architecture five hundred years before Christian religion was born.
