The Evil of Strength.—Violence as the outcome of passion, for example, of rage, must be understood from the physiological point of view as an attempt to avoid an imminent fit of suffocation. Innumerable acts arising from animal spirits and vented upon others are simply outlets for getting rid of sudden congestion by a violent muscular exertion: and perhaps the entire “evil of strength” must be considered from this point of view. (This evil of strength wounds others unintentionally—it must find an outlet somewhere; while the evil of weakness wishes to wound and to see signs of suffering.)
