have their limit. Most people have a heredity that is not the best nor yet the worst. Given an imperfect machine, they are thrown into a certain environment, and then up to the capacity of their machines the outcome depends entirely on the environment. Given an environment easy enough they will succeed, or at least "get by." Given a hard environment they will fail, or "go down." Tens of thousands of men live in a comparatively easy environment and pass their lives as useful citizens with no taint of criminality to their names, who under a hard environment would be found in prison. On the other hand, perhaps most of the inmates of prisons would have lived as respected citizens if their environment had not been so hard. Heredity has everything to do with making the machine strong and capable, or weak and useless; but when the machine is made and thrown on the world in its imperfect shape, environment has everything to do in determining what its fate shall be.
