You may call a jay a bird. Well, so he is, in a measure--because he's got feathers on him, and don't belong to no church, perhaps;but otherwise he is just as much a human as you be. And I'll tell you for why. A jay's gifts and instincts, and feelings, and interests, cover the whole ground. A jay hasn't got any more principle than a Congressman.
Mark TwainHe said that man’s 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.
Mark TwainWhen whole races and peoples conspire to propagate gigantic mute lies in the interest of tyrannies and shams, why should we care anything about the trifling lies told by individuals?
