"What is he doing with the pavement?" I wondered; and, having come up close to him, I discovered he was a young man from a butcher's shop, and was sharpening his knife on the flag-stone. He was not thinking about the stones when examining them, and still less while doing his work; he was merely sharpening his knife. It was necessary for him to do so in order to cut the meat, but to me it seemed that he was doing something to the pavement. In the same way mankind seems to be occupied with commerce, treaties, wars, sciences, arts; and yet for them one thing only is important, and they do only that,--they are elucidating those moral laws by which they live. Moral laws are already in existence, and mankind has been and is merely re-discovering them: this elucidation appears to be unimportant and imperceptible to one who has no need of moral law, and who does not desire to live by it. Yet this is not only the chief but is the sole business of all men. The elucidation is imperceptible in the same way as the difference between a sharp knife and a blunt one is imperceptible. A knife remains a knife; and one who has not to cut anything with it will not notice its edge: but for one who understands that all his life depends more or less upon whether his knife is blunt or sharp, every improvement in sharpening it is important; and such a man knows that there must be no limit to this improvement, and that the knife is only really a knife when it is sharp, and when it cuts what it has to cut. The conviction of this truth flashed upon me when I began to write my pamphlet. Previously it seemed to me that I knew everything about my subject, that I had a thorough understanding of everything connected with those questions which had been awakened in me by the impressions made in Liapin's house and during the census; but when I tried to sum them up, and to put them on paper, it turned out that the knife would not cut, and had to be sharpened: so it is only now after three years that I feel my knife is sharp enough for me to cut out what I want. It is not that I have learned new things: my thoughts are still the same; but they were blunt formerly; they kept diverging in every direction; there was no edge to them; nor was anything brought, as it is now, to one central point, to one most simple and plain conclusion. CHAPTER XIII I recollect that during the whole time of my unsuccessful endeavours to help the unfortunate inhabitants of Moscow, I felt I was like a man trying to help others out of a bog, who was all the time stuck fast in it himself. Every effort made me feel the instability of the ground upon which I was standing. I felt that I myself was in this bog, but the acknowledgement did not help me to look more closely under my feet to find out the nature of the ground on which I stood: I kept looking for some external means to remedy the evil.
