The fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt.
William James used to preach the ‘will-to-believe.’ For my part, I should wish to preach the ‘will-to-doubt.’ None of our beliefs are quite true. What is wanted is not the will to believe, but the will to find out, which is the exact opposite.
It’s a healthy thing to hang a question mark on the things you have long taken for granted.
The truly civilized man is always skeptical and tolerant. His culture is based on I am not too sure.
With most people, doubt about one thing is simply blind belief in another.
Believe nothing and be on your guard against everything.
