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.

This now insinuates itself, and henceforward our thought on the subject always takes the accustomed path, like brooks that are guided by ditches; to find a thought
