“I would not die for my beliefs because I might be wrong.”
“None of our beliefs are quite true, all have at least a penumbra of vagueness and error. The methods of increasing the degree of truth in our beliefs are well known; they consist of hearing all sides, trying to ascertain all the relevant facts, controlling our own bias by discussing with people who have the opposite bias, and cultivating a readiness to discard any hypothesis which has proved inadequate. These methods are practiced in science, and have built up the body of scientific knowledge.” – Bertrand Russell, British philosopher.
Louis May Alcott said,” He who believes is strong, he who doubt is weak. Strong convictions precede great actions.”
