“What social and industrial research has not sufficiently realised as yet is that… minor irrationalities of the “average normal” person are cumulative in their effect. They may not cause “breakdown” in the individual but they do cause “breakdown” in the industry.”

Context: You will perceive that economy, scientifically speaking, is a very contracted science; it is in fact a sort of vague mathematics which calculates the causes and effects of man's industry, and shows how it may be best applied. There are a multitude of allied branches of knowledge connected with mans condition; the relation of these to political economy is analogous to the connexion of mechanics, astronomy, optics, sound, heat, and every other branch more or less of physical science, with pure mathematics.

Context: Pornography does not cause rape or violence, which predate pornography by thousands of years. Rape and violence occur not because of patriarchal conditioning but because of the opposite, a breakdown of social controls.

Context: Remember, that though life is short, Thought and the influences of what we do or say, are immortal; and that no calculus has yet pretended to ascertain the law of proportion between cause and effect. The hammer of an English blacksmith, smiting down an insolent official, led to a rebellion which came near being a revolution. The word well spoken, the deed fitly done, even by the feeblest or humblest, cannot help but have their effect. More or less, the effect is inevitable and eternal. The echoes of the greatest deeds may die away like the echoes of a cry among the cliffs, and what has been done seem to the human judgment to have been without result. The unconsidered act of the poorest of men may fire the train that leads to the subterranean mine, and an empire be rent by the explosion.

Context: War isn't civilized. War is failure. It's the ultimate result of a breakdown in public policy, and soldiers are the machines that handle that breakdown. In warfare, you're taught to do whatever you have to, to stay alive.
