““Pragmatism emphasizes the irrationality of opinion, and psycho-analysis emphasizes the irrationality of conduct. Both have led many people to the view that there is no such thing as an ideal rationality to which opinion and conduct might with advantage conform. It would seem to follow that, if you and I hold different opinions, it is useless to appeal to argument, or to seek the arbitrament of an impartial outsider; there is nothing for us to do but fight it out, by the methods of rhetoric, advertisement, or warfare, according to the degree of our financial and military strength. I believe such an outlook to be very dangerous, and in the long run, fatal to civilization.””
