It may be, of course, that society is so constituted--or, rather, so lacking in constitution--that simple variations in brain physiology are the sufficient reason for its cataclysms; but a great many efforts will be made to prove the contrary before this highest of all spheres of human activity is declared to have no meaning--no thread which runs from age to age and links mankind, the genius and the man who plods, in a common and significant development.
In undertaking this task we must try to judge the genius with reference to the sane social man, the normal Socius.

What he is we have seen.

He is a person _who learns to judge by the judgments of society_.

What, then, shall we say of the genius from this point of view?
Can the hero worshipper be right in saying that the genius teaches society to judge; or shall we say that the genius, like other men, must learn to judge by the judgments of society?
The most fruitful point of view is, no doubt, that which considers the genius a variation.

And unless we do this it is evidently impossible to get any theory which will bring him into a general scheme.
