I, for instance, have all my life been busy with mental work. I had said to myself that I have thus divided the labour: that my special work is writing; that is, mental labour: and all other works necessary for me, I left to be done by other men, or rather compelled them to do it. But this arrangement, seemingly so convenient for mental labour, though unjust, became most inconvenient, especially for mental labour. I have been writing all my life, have accommodated my food, sleep, amusements, with reference to this special labour, and besides this work I did nothing. The results of which were, first, that I had been narrowing the circle of my observation and information, and often I had not any object to study, and therefore, having had to describe the life of men (the life of men is a continual problem of every mental activity), I felt my ignorance, and had to learn and to ask about such things, which everyone not occupied with a special work knows; secondly, it happened that when I sat down to write, I often had no inward inclination to write, and nobody wanted my writing for itself, that is, for my thoughts, but people merely wanted my name for profits in the magazines. I made great efforts to write what I could; sometimes I did not succeed at all; sometimes succeeded in writing something very bad, and I felt dissatisfied and miserable. So often and often weeks passed, during which I would eat, drink, sleep, warm myself, and do nothing--or do something of no use to anybody--i.e., commit the worst and meanest crime, scarcely ever committed by a man of the working class. But since I have acknowledged the necessity of physical labour as well as hard labour, and also that of handicraft, everything is quite different: my time is occupied however humbly, but certainly in a useful way, and pleasantly and instructively for me. Therefore I, for the sake of my speciality, leave off this undoubtedly useful and pleasant occupation, only when I feel an inward want, or see a direct demand for my literary work. And this caused the quality, and therefore the usefulness and pleasantness, of my special labour to improve. Thus it has happened that my occupation with those physical works, which are necessary for me as well as for every man, not only do not interfere with my special activity, but are a necessary condition of the utility, quality, and pleasantness of this activity. A bird is so created that it is necessary for it to fly, to walk, to peck, to consider; and when it does all this, it is satisfied and happy; then it is a bird. Exactly so with a man when he walks, turns over heavy things, lifts them up, carries them, works with his fingers, eyes, ears, tongue, brain, then only is he satisfied, then only is he _a man_.
