Good is like gold, it will not rust or tarnish and it is rare, but there is some of it everywhere. Evil is like water, it abounds, is cheap, soon fouls, but runs itself clear of taint.

Context

“The moral guilt of an action varies inversely as the squares of its distances in time and space, social, psychological, physiological or topographical, from ourselves. Not so its moral merit: this loses no lustre through time and distance. Good is like gold, it will not rust or tarnish and it is rare, but there is some of it everywhere. Evil is like water, it abounds, is cheap, soon fouls, but runs itself clear of taint. Myself and My Books Bodily offspring I do not leave, but mental offspring I do. Well, my books do not have to be sent to school and college and then insist on going into the Church or take to drinking or marry their mother’s maid.” source
