Directly or indirectly, the desire for money, which then meant every good thing, was the motive of all this crime, the taproot of a vast poison growth, which the machinery of law, courts, and police could barely prevent from choking your civilization outright.

When we made the nation the sole trustee of the wealth of the people, and guaranteed to all abundant maintenance, on the one hand abolishing want, and on the other checking the accumulation of riches, we cut this root, and the poison tree that overshadowed your society withered, like Jonah's gourd, in a day.

As for the comparatively small class of violent crimes against persons, unconnected with any idea of gain, they were almost wholly confined, even in your day, to the ignorant and bestial; and in these days, when education and good manners are not the monopoly of a few, but universal, such atrocities are scarcely ever heard of.

You now see why the word 'atavism' is used for crime.

It is because nearly all forms of crime known to you are motiveless now, and when they appear can only be explained as the outcropping of ancestral traits.
