This guy is often just so spot on that it is maddening but at the same time it reinforces what you feel at a gut level. The truth is often not very comfortable, far from it but in a world filled with subjective opinions, it's what little we have to hang onto.
“If you wish to become a philosopher, the first thing to realise is that most people go through life with a whole world of beliefs that have no sort of rational justification, and that one man’s world of beliefs is apt to be incompatible with another man’s, so that they cannot both be right. People’s opinions are mainly designed to make them feel comfortable; truth, for most people is a secondary consideration.”
― Bertrand Russell, The Art of Philosophizing and other Essays (1942)
Sometimes a person's philosophy is based on mis-information of evidence mis-interpreted. For instance,, people do evil things, therefore people are evil. Religion takes this one step futher by teaching that people are inherently evil.
