If you read on and on without setting your own thoughts to work, what you have read can not strike root, and is generally lost. It is, in fact, just the same with mental as with bodily food: hardly the fifth part of what one takes is assimilated. The rest passes off in evaporation, respiration and the like. The result of all this is that thoughts put on paper are nothing more than footsteps in the sand: you see the way the man has gone, but to know what he saw on his walk, you want his eyes. There is no quality of style that can be gained by reading writers who possess it; whether it be persuasiveness, imagination, the gift of drawing comparisons, boldness, bitterness, brevity, grace, ease of expression or wit, unexpected contrasts, a laconic or naive manner, and the like. But if these qualities are already in us, exist, that is to say, potentially, we can call them forth and bring them to consciousness; we can learn the purposes to which they can be put; we can be strengthened in our inclination to use them, or get courage to do so; we can judge by examples the effect of applying them, and so acquire the correct use of them; and of course it is only when we have arrived at that point that we actually possess these qualities. The only way in which reading can form style is by teaching us the use to which we can put our own natural gifts. We must have these gifts before we begin to learn the use of them. Without them, reading teaches us nothing but cold, dead mannerisms and makes us shallow imitators. The strata of the earth preserve in rows the creatures which lived in former ages; and the array of books on the shelves of a library stores up in like manner the errors of the past and the way in which they have been exposed. Like those creatures, they too were full of life in their time, and made a great deal of noise; but now they are stiff and fossilized, and an object of curiosity to the literary palaeontologist alone. Herodotus relates that Xerxes wept at the sight of his army, which stretched further than the eye could reach, in the thought that of all these, after a hundred years, not one would be alive. And in looking over a huge catalogue of new books, one might weep at thinking that, when ten years have passed, not one of them will be heard of.
