Context

“they do not enjoy life enough to wish to beget children. At this point the unduly strenuous philosophy which they have carried over from their Puritan forefathers shows itself unadapted to the world. Those whose outlook on life causes them to feel so little happiness that they do not care to beget children are biologically doomed. Before very long they must be succeeded by something gayer and jollier. Competition considered as the main thing in life is too grim, too tenacious, too much a matter of taut muscles and intent will, to make a possible basis of life for more than one or two generations at most.” source
