Morality in sexual relations, when it is free from superstition, consists essentially in respect for the other person, and unwillingness to use that … - Bertrand Russell

"Some care is needed in using Descartes' argument. "I think, therefore I am" says rather more than is strictly certain. It might seem as though we are quite sure of being the same person to-day as we were yesterday, and this is no doubt true in some sense. But the real Self is as hard to arrive at as the real table, and does not seem to have that absolute, convincing certainty that belongs to particular experiences."

The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.

What a queer work the Bible is. ...Some texts are very funny. Deut. XXIV, 5: "When a man hath taken a new wife, he shall not go out to war, neither shall he be charged with any business: but he shall be free at home one year, and shall cheer up his wife which he hath taken." I should never have guessed "cheer up" was a Biblical expression. Here is another really inspiring text: "Cursed be he that lieth with his mother-in-law. And all the people shall say, Amen." St Paul on marriage: "I say therefore to the unmarried and widows, It is good for them if they abide even as I. But if they cannot contain, let them marry: for it is better to marry than to burn." This has remained the doctrine of the Church to this day. It is clear that the Divine purpose in the text "it is better to marry than to burn" is to make us all feel how very dreadful the torments of Hell must be.
