At least two-thirds of our miseries spring from human stupidity, human malice and those great motivators and justifiers of malice and stupidity: idealism, dogmatism and proselytising zeal on behalf of religious or political ideas.
Any lie will receive almost instant corroboration, and almost instant collaboration,
if the maintenance of it results in the public enjoyment of
someone else's pain, someone else's humiliation.
— Dennis Potter (The Singing Detective)
