"Assume that you are quite right. You are depressed because you have every reason to be depressed. No member of the other two million species which inhabit the earth - and who are luckily exempt from depression - would fail to be depressed if it lived the life you lead. You live in a deranged age - more deranged than usual, because despite great scientific and technological advances, man has not the faintest idea of who he is or what he is doing."
