For the little knowledge of that unlearned man is living, because every fact that is known to him is supported by accurate and well-apprehended perception, and thus represents for him a thousand similar facts. On the contrary, the much knowledge of the ordinary scholar is _dead_, because even if it does not consist, as is often the case, in mere words, it consists entirely in abstract knowledge. This, however, receives its value only through the _perceptive_ knowledge of the individual with which it must connect itself, and which must ultimately realise all the conceptions. If now this perceptive knowledge is very scanty, such a mind is like a bank with liabilities tenfold in excess of its cash reserve, whereby in the end it becomes bankrupt. Therefore, while the right apprehension of the perceptible world has impressed the stamp of insight and wisdom on the brow of many an unlearned man, the face of many a scholar bears no other trace of his much study than that of exhaustion and weariness from excessive and forced straining of the memory in the unnatural accumulation of dead conceptions. Moreover, the insight of such a man is often so puerile, so weak and silly, that we must suppose that the excessive strain upon the faculty of indirect knowledge, which is concerned with abstractions, directly weakens the power of immediate perceptive knowledge, and the natural and clear vision is more and more blinded by the light of books. At any rate the constant streaming in of the thoughts of others must confine and suppress our own, and indeed in the long run paralyse the power of thought if it has not that high degree of elasticity which is able to withstand that unnatural stream. Therefore ceaseless reading and study directly injures the mind—the more so that completeness and constant connection of the system of our own thought and knowledge must pay the penalty if we so often arbitrarily interrupt it in order to gain room for a line of thought entirely strange to us. To banish my own thought in order to make room for that of a book would seem to me like what Shakespeare censures in the tourists of his time, that they sold their own land to see that of others. Yet the inclination for reading of most scholars is a kind of _fuga vacui_, from the poverty of their own minds, which forcibly draws in the thoughts of others. In order to have thoughts they must read something; just as lifeless bodies are only moved from without; while the man who thinks for himself is like a living body that moves of itself. Indeed it is dangerous to read about a subject before we have thought about it ourselves. For along with the new material the old point of view and treatment of it creeps into the mind, all the more so as laziness and apathy counsel us to accept what has already been thought, and allow it to pass for truth. This now insinuates itself, and henceforward our thought on the subject always takes the accustomed path, like brooks that are
