Monetary calculation is not the calculation, and certainly not the measurement, of value. Its basis is the comparison of the more important and the less important. It is an ordering according to rank, an act of grading (Cuhel), and not an act of measuring. It was a mistake to search for a measure of the value of goods. In the last analysis, economic calculation does not rest on the measurement of values, but on their arrangement in an order of rank.
Ludwig von MisesAs society is only possible if everyone, while living his own life, at the same time helps others to live; if every individual is simultaneously means and end; if each individual's well-being is simultaneously the condition necessary to the well-being of others, it is evident that the contrast between I and thou, means and end, automatically is overcome.
Ludwig von MisesWithout calculation, economic activity is impossible. Since under Socialism economic calculation is impossible, under Socialism there can be no economic activity in our sense of the word All economic change, therefore, would involve operations the value of which could neither be predicted beforehand nor ascertained after they had taken place. Everything would be a leap in the dark. Socialism is the renunciation of rational economy.
