The scientific _thinker_ also does this to a much greater extent. Although he requires much knowledge and must read a great deal, his mind is nevertheless strong enough to overcome it all, to assimilate it, to incorporate it with the system of his thoughts, and to subordinate it to the organic relative unity of his insight, which is vast and ever-growing. By this means his own thought, like the bass in an organ, always takes the lead in everything, and is never deadened by other sounds, as is the case with purely antiquarian minds; where all sorts of musical passages, as it were, run into each other, and the fundamental tone is entirely lost. * * * * * The people who have spent their lives in reading and acquired their wisdom out of books resemble those who have acquired exact information of a country from the descriptions of many travellers. These people can relate a great deal about many things; but at heart they have no connected, clear, sound knowledge of the condition of the country. While those who have spent their life in thinking are like the people who have been to that country themselves; they alone really know what it is they are saying, know the subject in its entirety, and are quite at home in it. * * * * * The ordinary book-philosopher stands in the same relation to a man who thinks for himself as an eye-witness does to the historian; he speaks from his own direct comprehension of the subject. Therefore all who think for themselves hold at bottom much the same views; when they differ it is because they hold different points of view, but when these do not alter the matter they all say the same thing. They merely express what they have grasped from an objective point of view. I have frequently hesitated to give passages to the public because of their paradoxical nature, and afterwards to my joyful surprise have found the same thoughts expressed in the works of great men of long ago. The book-philosopher, on the other hand, relates what one man has said and another man meant, and what a third has objected to, and so on. He compares, weighs, criticises, and endeavours to get at the truth of the thing, and in this way resembles the critical historian. For instance, he will try to find out whether Leibnitz was not for some time in his life a follower of Spinoza, etc. The curious student will find striking examples of what I mean in Herbart's _Analytical Elucidation of Morality and Natural Right_, and in his _Letters on Freedom_. It surprises us that such a man should give himself so much trouble; for it is evident that if he had fixed his attention on the matter he would soon have attained his object by thinking a little for himself.
