It is precisely minds of the first order that will never be specialists. For their very nature is to make the whole of existence their problem; and this is a subject upon which they will every one of them in some form provide mankind with a new revelation. For he alone can deserve the name of genius who takes the All, the Essential, the Universal, for the theme of his achievements; not he who spends his life in explaining some special relation of things one to another.
ON THINKING FOR ONESELF.
A library may be very large; but if it is in disorder, it is not so useful as one that is small but well arranged. In the same way, a man may have a great mass of knowledge, but if he has not worked it up by thinking it over for himself, it has much less value than a far smaller amount which he has thoroughly pondered. For it is only when a man looks at his knowledge from all sides, and combines the things he knows by comparing truth with truth, that he obtains a complete hold over it and gets it into his power. A man cannot turn over anything in his mind unless he knows it; he should, therefore, learn something; but it is only when he has turned it over that he can be said to know it.
Reading and learning are things that anyone can do of his own free will; but not so thinking. Thinking must be kindled, like a fire by a draught; it must be sustained by some interest in the matter in hand. This interest may be of purely objective kind, or merely subjective. The latter comes into play only in things that concern us personally. Objective interest is confined to heads that think by nature; to whom thinking is as natural as breathing; and they are very rare. This is why most men of learning show so little of it.
It is incredible what a different effect is produced upon the mind by thinking for oneself, as compared with reading. It carries on and intensifies that original difference in the nature of two minds which leads the one to think and the other to read. What I mean is that reading forces alien thoughts upon the mind—thoughts which are as foreign to the drift and temper in which it may be for the moment, as the seal is to the wax on which it stamps its imprint. The mind is thus entirely under compulsion from without; it is driven to think this or that, though for the moment it may not have the slightest impulse or inclination to do so.
But when a man thinks for himself, he follows the impulse of his own mind, which is determined for him at the time, either by his environment or some particular recollection. The visible world of a man's surroundings does not, as reading does, impress a single definite thought upon his mind, but merely gives the matter and occasion which lead him to think what is appropriate to his nature and present temper. So it is, that much reading deprives the mind of all elasticity; it is like keeping a spring continually under pressure. The safest way of having no thoughts of one's own is to take up a book every moment one has nothing else to do. It is this practice which explains why erudition makes most men more stupid and silly than they are by nature, and prevents their writings obtaining any measure of success. They remain, in Pope's words:
For ever reading, never to be read![10]
