ABSTRACT
The scientific society which has been sketched in the chapters of this Part is, of course, not to be taken altogether as serious prophecy. It is an attempt to depict the world which would result if scientific technique were to rule unchecked. The reader will have observed that features that everyone would consider desirable are almost inextricably mingled with features that are repulsive. The reason of this is that we have been imagining a society developed in accordance with certain ingredients of human nature to the exclusion of all others. As ingredients they are good; as the sole driving force they are likely to be disastrous. The impulse towards scientific construction is admirable when it does not thwart any of the major impulses that give value to human life, but when it is allowed to forbid all outlet to everything but itself it becomes a form of cruel tyranny. There is, I think, a real danger lest the world should become subject to a tyranny of this sort, and it is on this account that I have not shrunk from depicting the darker features of the world that scientific manipulation unchecked might wish to create.
