“The insistence of the Christian doctrine on man's limited condition was somehow enough of a philosophy to allow its adherents a very deep insight into the essential inhumanity of all those modern attempts – psychological, technical, biological – to change man into the monster of superman. They realized that a pursuit of happiness which actually means to wipe away all tears will pretty quickly end by wiping out all laughter. It was again Christianity which taught them that nothing human can exist beyond tears and laughter, except the silence of despair.”
