Everyone knows enough to condemn what he takes to be no good, but no one knows enough to condemn what he has already taken to be good. This is how the great confusion comes about, blotting out the brightness of sun and moon above, searing the vigor of, hills and streams below, overturning the round of the four seasons in between. There is no insect that creeps and crawls, no creature that flutters and flies that has not lost its inborn nature. So great is the confusion of the world that comes from coveting knowledge!
