I believe that now and always the conscious selection of the best for reproduction will be impossible; that to propose it is to display a fundamental misunderstanding of what individuality implies.

It is in the sterilization of failure, and not in the selection of successes for breeding, that the possibility of an improvement of the human stock lies.

We live in reference to past experience and not to future events, however inevitable.

Human society is based on want. Life is based on want. Wild-eyed visionaries may dream of a world without need. Cloud-cuckoo-land. It can't be done.
