Now since learning is nothing but imitation, it follows that the greatest ability and teachableness (capacity) regarded qu teachableness, cannot avail for genius. Even if a man thinks or invents for himself, and does not merely take in what others have taught, even if he discovers many things in art and science, this is not the right ground for calling such a (perhaps great) head, a genius (as opposed to him who because he can only learn and imitate is called a shallow-pate ). For even these things could be learned, they lie in the natural path of him who investigates and reflects according to rules; and they do not differ specifically from what can be acquired by industry through imitation. Thus we can readily learn all that Newton has set forth in his immortal work on the Principles of Natural Philosophy, however great a head was required to discover it; but we cannot learn to write spirited poetry, however express may be the precepts of the art and however excellent its models. The reason is that Newton could make all his steps, from the first elements of geometry to his own great and profound discoveries, intuitively plain and definite as regards consequence, not only to himself but to every one else. But a Homer or a Wieland cannot show how his Ideas, so rich in fancy and yet so full of thought, come together in his head, simply because he does not know and therefore cannot teach others. In
