He said that manโs heart was the only bad heart in the animal kingdom; that man was the only animal capable of feeling malice, envy, vindictiveness, revengefulness, hatred, selfishness, the only animal that loves drunkenness, almost the only animal that could endure personal uncleanliness and a filthy habitation, the sole animal in whom was fully developed the base instinct called patriotism, the sole animal that robs, persecutes, oppresses and kills members of his own tribe, the sole animal that steals and enslaves the members of any tribe.
