The Tragic Sense of Life (1913), Conclusion : Don Quixote in the Contemporary European Tragi-Comedy
Context: The philosophy of Bergson, which is a spiritualist restoration, essentially mystical, medieval, Quixotesque, has been called a demi-mondaine philosophy. Leave out the demi; call it mondaine, mundane. Mundane — yes, a philosophy for the world and not for philosophers, just as chemistry ought to be not for chemists alone. The world desires illusion (mundus vult decipi) — either the illusion antecedent to reason, which is poetry, or the illusion subsequent to reason, which is religion. And Machiavelli has said that whosoever wishes to delude will always find someone willing to be deluded. Blessed are they who are easily befooled!

“Deceiving others. That is what the world calls a romance.”

“We do not want a religion that deceives us for our own good.”

The Psychology of Man's Possible Evolution (1950)
Context: People who think they can control their negative emotions and manifest them when they want to, simply deceive themselves. Negative emotions depend on identification; if identification is destroyed in some particular case, they disappear. The strangest and most fantastic fact about negative emotions is that people actually worship them. I think that, for an ordinary mechanical man, the most difficult thing to realise is that his own and other people's negative emotions, have no value whatever and do not contain anything noble, anything beautiful or anything strong. In reality negative emotions contain nothing but weakness and very often the beginning of hysteria, insanity or crime. The only good thing about them is that, being quite useless and artificially created by imagination and identification, they can be destroyed without any loss. And this is the only chance of escape that man has.
