" 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; 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 in hearing all
sides, trying to ascertain all the relevant facts, controlling our
own bias by discussion with people who have the opposite
bias, and cultivating a readiness to disregard any hypothesis
which has proved inadequate…
In religion and politics, on the contrary, though there is
as yet nothing approaching scientific knowledge, everybody
considers it de rigueur to have a dogmatic opinion, to be
backed up by inflicting starvation, prison, and war, and to
be carefully guarded from argumentative competition with
any different opinion. "

― Bertrand Russell , Free Thought and Official Propaganda
