The world would count itself happier if, during the Great War, only twenty-five per cent of the population of belligerent lands had been murderers, virtually or in fact.

There is something to be gained, and that something is well worth while.
Still, whether we like it or not, the task of speeding up the decrease of the human population becomes increasingly urgent.[31] To many of our Undesirables it may seem, mere sentiment to trouble about the ravishing of the world's beauty or the ravaging of the world's humanity.

But certain hard facts, even to-day, have to be faced.

The process of mechanical invention continues every day on an ever increasing scale of magnitude.
Now that process, however necessary, however beneficial, involves some of the chief evils of our present phase of what we call civilisation, partly because it has deteriorated the quality of all human products and partly because it has enslaved mankind, and in so doing deteriorated also his quality.[32] Now we cannot abolish machinery, because machinery lies in the very essence of life and we ourselves are machines.

But, as the largest part of history shows, there is no need whatever for man to become the slave of machinery, or even for machinery to injure the quality of his own work; rightly used it may improve it.
