The collectivists say, "To each according to his deeds"; or, in other terms, according to his share of services rendered to society. They think it expedient to put this principle into practice, as soon as the Social Revolution will have made all instruments of production common property. But we think that if the Social Revolution had the misfortune of proclaiming such a principle, it would mean its necessary failure; it would mean leaving the social problem, which past centuries have burdened us with, unsolved. Of course, in a society like ours, in which the more a man works the less he is remunerated, this principle, at first sight, may appear to be a yearning for justice. But in reality it is only the perpetuation of injustice. It was by proclaiming this principle that wagedom began, to end in the glaring inequalities and all the abominations of present society; because, from the moment work done began to be appraised in currency, or in any other form of wage, the day it was agreed upon that man would only receive the wage he should be able to secure to himself, the whole history of a State-aided Capitalist Society was as good as written; it was contained in germ in this principle. Shall we, then, return to our starting-point, and go through the same evolution again? Our theorists desire it, but fortunately it is impossible. The Revolution, we maintain, must be communist; if not, it will be drowned in blood, and have to be begun over again. Services rendered to society, be they work in factory or field, or mental services, _cannot be_ valued in money. There can be no exact measure of value (of what has been wrongly termed exchange value), nor of use value, in terms of production. If two individuals work for the community five hours a day, year in year out, at different work which is equally agreeable to them, we may say that on the whole their labour is approximately equivalent. But we cannot divide their work, and say that the result of any particular day, hour, or minute of work of the one is worth the result of one day, one hour, or one minute of the other. We may roughly say that the man, who during his lifetime has deprived himself of leisure during ten hours a day has given far more to society than the one who has only deprived himself of leisure during five hours a day, or who has not deprived himself at all. But we cannot take what he has done during two hours, and say that the yield of his two hours' work is worth twice as much as the yield of another individual, who has worked only one hour, and remunerate the two in proportion. It would be disregarding all that is complex in industry, in agriculture, in the whole life of present society; it would be ignoring to what extent all individual work is the result of the past and the present labour of society as a whole. It would mean believing ourselves to be living in the Stone Age, whereas we are living in an age of steel.
