After these considerations, it will not be matter for surprise that a man who thinks for himself can easily be distinguished from the book-philosopher by the very way in which he talks, by his marked earnestness, and the originality, directness, and personal conviction that stamp all his thoughts and expressions. The book-philosopher, on the other hand, lets it be seen that everything he has is second-hand; that his ideas are like the number and trash of an old furniture-shop, collected together from all quarters. Mentally, he is dull and pointless--a copy of a copy. His literary style is made up of conventional, nay, vulgar phrases, and terms that happen to be current; in this respect much like a small State where all the money that circulates is foreign, because it has no coinage of its own. Mere experience can as little as reading supply the place of thought. It stands to thinking in the same relation in which eating stands to digestion and assimilation. When experience boasts that to its discoveries alone is due the advancement of the human race, it is as though the mouth were to claim the whole credit of maintaining the body in health. The works of all truly capable minds are distinguished by a character of _decision_ and _definiteness_, which means they are clear and free from obscurity. A truly capable mind always knows definitely and clearly what it is that it wants to express, whether its medium is prose, verse, or music. Other minds are not decisive and not definite; and by this they may be known for what they are. The characteristic sign of a mind of the highest order is that it always judges at first hand. Everything it advances is the result of thinking for itself; and this is everywhere evident by the way in which it gives its thoughts utterance. Such a mind is like a Prince. In the realm of intellect its authority is imperial, whereas the authority of minds of a lower order is delegated only; as may be seen in their style, which has no independent stamp of its own. Every one who really thinks for himself is so far like a monarch. His position is undelegated and supreme. His judgments, like royal decrees, spring from his own sovereign power and proceed directly from himself. He acknowledges authority as little as a monarch admits a command; he subscribes to nothing but what he has himself authorized. The multitude of common minds, laboring under all sorts of current opinions, authorities, prejudices, is like the people, which silently obeys the law and accepts orders from above.
