Within the cultivated races, however, man has practically ceased to evolve, at least in so far as concerns the main lines on which his Evolution has thus far proceeded. For in creating the artificial conditions of civilisation, he refuses any longer to be governed by the stern law of nature, which decides that the fit shall live and multiply, and the unfit surely perish. There is in fact evidence that conditions of civilisation are making for retrogression rather than for progress, a state of affairs that is worthy of the most serious consideration. The only rational and scientific remedy that has been offered for this state of affairs is the institution of some moderate system of artificially guiding man's further Evolution.
