Manual labourers--_i.e._ navvies, coal-heavers, miners, etc.--are naturally more or less brutal. Their brain-cells at birth offered so little resistance to the evil occult influences that they received, in full, all the lower germs of thought inoculated by the occult brains. Drink, gluttony, cruelty, all came to their infant cerebrums cotemporaneously. The cruelty germ develops first, and cats, dogs, donkeys, smaller brothers, and even babies are made to feel the superior physical strength of the early wearer of hobnails. He is obsessed with a mania for hurting something, and with his strongly innate instinct of self-preservation, invariably chooses something that cannot harm him. Daily he looks around for fresh victims, and finally decides that the weedy offspring of the hated superior classes are the easiest prey. In company with others of his species, he annihilates the boy in Etons on his way to and from school, and the after recollections of the weakling's bloody nose and teardrops are as nectar to him. The cruelty germ develops apace. The bloody noses of the well-dressed classes are his mania now. He sees them at every turn and even dreams of them. He grows to manhood, and either digs in the road or plies the pick and shovel underground. The mechanical, monotonous exercise and the sordidness of his home surroundings foster the germ, and his leisure moments are occupied with the memory of those glorious times when he was hitting out at someone, and he feels he would give anything just to have one more blow. Curse the police! If it were not for them he could indulge his hobby to the utmost. But the stalwart, officious man in blue is ever on the scene, and the thrashing of a puny cleric or sawbones is scarcely compensation for a month's hard labour. Yet his mania must be satisfied somehow--it worries him to pieces. He must either smash someone's nose or go mad; there is no alternative, and he chooses the former. The Society for the Prevention of Cruelty to Animals prevents him skinning a cat; the National Society for the Prevention of Cruelty to Children will be down on him at once if he strikes a child, and so he has no other resource left but his wife--he can knock out all her teeth, bash in her ribs, and jump on her head to his heart's content. She will never dare prosecute him, and, if she does, some Humanitarian Society will be sure to see that he is not legally punished. He thus finds safe scope for the indulgence of his crank, and when there is nothing left of his own wife, he turns his unattractive and pusillanimous attentions to someone else's. But occult thought-germs of this elementary type only thrive where the infant's spiritual or unknown brain is wholly undeveloped. Where the spiritual or unknown brain of an infant is partially developed, the germ-thought to be lodged in it (especially if it be a germ-thought of cruelty) must be of a more subtle and refined nature.
