All these so-called theories rely upon facts--so far as they have any facts to rest upon--which, if space permitted, we might readily estimate from our present point of view.

In so far as a really great man busies himself mainly with things that are objective, which are socially and morally neutral--such as electricity, natural history, mechanical theory, with the applications of these--of course, the mental capacity which he possesses is the main thing, and his absorption in these things may lead to a warped sense of the more ideal and refined relationships which are had in view by the writer in quest for degeneracy.

It will still be admitted, however, by those who are conversant with the history of science, that the greatest scientific geniuses have been men of profound quietness of life and normal social development.

It is to the literary and artistic genius that the seeker after abnormality has to turn; and in this field, again, the facts serve to show their own meaning.
As a general rule, these artistic prodigies do not represent the union of variations which we find in the greatest genius.

Such men are often distinctly lacking in power of sustained constructive thought.
