Thus, the generous laborer, giving more of a day's work for less return (measured in terms of food and shelter), threatens the life of his less generous brother laborer, and, at the best, if he does not destroy that life, he diminishes it. Whereupon the less generous laborer looks upon him as an enemy, and, as men are inclined to do in a tooth-and-nail society, he tries to kill the man who is trying to kill him.

When a striker kills with a brick the man who has taken his place, he has no sense of wrong-doing. In the deepest holds of his being, though he does not reason the impulse, he has an ethical sanction. He feels dimly that he has justification, just as the home-defending Boer felt, though more sharply, with each bullet he fired at the invading English. Behind every brick thrown by a striker is the selfish "will to live" of himself and the slightly altruistic will to live of his family. The family-group came into the world before the state-group, and society being still on the primitive basis of tooth and nail, the will to live of the state is not so compelling to the striker as the will to live of his family and himself.

In addition to the use of bricks, clubs, and bullets, the selfish laborer finds it necessary to express his feelings in speech. Just as the peaceful country-dweller calls the sea-rover a "pirate," and the stout burgher calls the man who breaks into his strong-box a "robber," so the selfish laborer applies the opprobrious epithet "scab" to the laborer who takes from him food and shelter by being more generous in the disposal of his labor-power. The sentimental connotation of scab is as terrific as that of " traitor" or "Judas," and a sentimental definition would be as deep and varied as the human heart. It is far easier to arrive at what may be called a technical definition, worded in commercial terms, as, for instance, that a scab is one who gives more value for the same price than another.

The laborer who gives more time, or strength, or skill, for the same wage, than another, or equal time, or strength, or skill, for a less wage, is a scab. This generousness on his part is hurtful to his fellow laborers, for it compels them to an equal generousness which is not to their liking, and which gives them less of food and shelter. But a word may be said for the scab. Just as his act makes his rivals compulsorily generous, so do they, by fortune of birth and training, make compulsory his act of generousness. He does not scab because he wants to scab. No whim of the spirit, no burgeoning of the heart, leads him to give more of his labor-power than they for a certain sum.

It is because he cannot get work on the same terms as they that he is a scab. There is less work than there are men to do work. This is patent, else the scab would not loom so large on the labor-market horizon. Because they are stronger than he, or more skilled, or more fortunate, or more energetic, it is impossible for him to take their places at the same wage. To take their places he must give more value, must work longer hours, or receive a smaller wage. He does so, and he cannot help it, for his will to live is driving him on as well as they are being driven on by theirs, and to live he must win food and shelter, which he can do only by receiving permission to work from some man who owns a bit of land or piece of machinery. And to receive permission from this man, he must make the transaction profitable for him.
