Blind impulses sometimes lead to destruction and death, but at other times they lead to the best things the world contains. Blind impulse is the source of war, but it is also the source of science, and art, and love. It is not the weakening of impulse that is to be desired, but the direction of impulse towards life and growth rather than towards death and decay.
