We must hold firmly to our identification, because among the principal reasons which have prevented Aesthetic, the science of art, from revealing the true nature of art, its real roots in human nature, has been its separation from the general spiritual life, the having made of it a sort of special function or aristocratic circle. No one is astonished when he learns from physiology that every cellule is an organism and every organism a cellule or synthesis of cellules. No one is astonished at finding in a lofty mountain the same chemical elements that compose a small stone or fragment. There is not one physiology of small animals and one of large animals; nor is there a special chemical theory of stones as distinct from mountains. In the same way, there is not a science of lesser intuition distinct from a science of greater intuition, nor one of ordinary intuition distinct from artistic intuition. There is but one Aesthetic, the science of intuitive or expressive knowledge, which is the aesthetic or artistic fact. And this Aesthetic is the true analogy of Logic. Logic includes, as facts of the same nature, the formation of the smallest and most ordinary concept and the most complicated scientific and philosophical system. [Sidenote] _Artistic genius._ Nor can we admit that the word _genius_ or artistic genius, as distinct from the non-genius of the ordinary man, possesses more than a quantitative signification. Great artists are said to reveal us to ourselves. But how could this be possible, unless there be identity of nature between their imagination and ours, and unless the difference be only one of quantity? It were well to change _poeta nascitur_ into _homo nascitur poeta_: some men are born great poets, some small. The cult and superstition of the genius has arisen from this quantitative difference having been taken as a difference of quality. It has been forgotten that genius is not something that has fallen from heaven, but humanity itself. The man of genius, who poses or is represented as distant from humanity, finds his punishment in becoming or appearing somewhat ridiculous. Examples of this are the _genius_ of the romantic period and the _superman_ of our time. But it is well to note here, that those who claim unconsciousness as the chief quality of an artistic genius, hurl him from an eminence far above humanity to a position far below it. Intuitive or artistic genius, like every form of human activity, is always conscious; otherwise it would be blind mechanism. The only thing that may be wanting to the artistic genius is the _reflective_ consciousness, the superadded consciousness of the historian or critic, which is not essential to artistic genius.
