Leo Tolstoy on Theory

“And don't all the theories of philosophy do the same, trying by the path of thought, which is strange and not natural to man, to bring him to a knowledge of what he has known long ago, and knows so certainly that he could not live at all without it? Isn't it distinctly to be seen in the development of each philosopher's theory, that he knows what is the chief significance of life beforehand, just as positively as the peasant Fyodor, and not a bit more clearly than he, and is simply trying by a dubious intellectual path to come back to what everyone knows?”

“Their ideas seemed to him fruitful when he was reading or was himself seeking arguments to refute other theories, especially those of the materialists; but as soon as he began to read or sought for himself a solution of problems, the same thing always happened. As long as he followed the fixed definition of obscure words such as spirit, will, freedom, essence, purposely letting himself go into the snare of words the philosophers set for him, he seemed to comprehend something. But he had only to forget the artificial train of reasoning, and to turn from life itself to what had satisfied him while thinking in accordance with the fixed definitions, and all this artificial edifice fell to pieces at once like a house of cards, and it became clear that the edifice had been built up out of those transposed words, apart from anything in life.”
