If we look again into the vice and sin that undoubtedly disfigure the world we shall find much reason to believe that what is exceptional in human nature is not the evil tendency but the restraining conscience, and that it is chiefly the weakness of the distinctively human quality that is the origin of the evil. It is impossible indeed, with the knowledge we now possess, to deny to animals some measure both of reason and of the moral sense. In addition to the higher instincts of parental affection and devotion which are so clearly developed we find among some animals undoubted signs of remorse, gratitude, affection, self-sacrifice. Even the point of honour which attaches shame to some things and pride to others may be clearly distinguished. No one who has watched the more intelligent dog can question this, and many will maintain that in some animals, though both good and bad qualities are less widely developed than in man, the proportion of the good to the evil is more favourable in the animal than in the man. At the same time in the animal world desire is usually followed without any other restraint than fear, while in man it is largely though no doubt very imperfectly limited by moral self-control. Most crimes spring not from anything wrong in the original and primal desire but from the imperfection of this higher, distinct or superadded element in our nature. The crimes of dishonesty and envy, when duly analysed, have at their basis simply a desire for the desirable--a natural and inevitable feeling. What is absent is the restraint which makes men refrain from taking or trying to take desirable things that belong to another. Sensual faults spring from a perfectly natural impulse, but the restraint which confines the action of that impulse to defined circumstances is wanting. Much, too, of the insensibility and hardness of the world is due to a simple want of imagination which prevents us from adequately realising the sufferings of others. The predatory, envious and ferocious feelings that disturb mankind operate unrestrained through the animal world, though man's superior intelligence gives his desires a special character and a greatly increased scope, and introduces them into spheres inconceivable to the animal. Immoderate and uncontrolled desires are the root of most human crimes, but at the same time the self-restraint that limits desire, or self-seeking, by the rights of others, seems to be mainly, though not wholly, the prerogative of man.
