Abstract
There can be no possible quarrel with the assertion that the phenomena of value are amenable to scientific treatment if the statement is taken in an obvious sense, for the act of valuation is a fact of human experience, empirically observable in the same way as any other fact. There is therefore no reason why we should not deal with certain aspects of the phenomena of value as we deal with other empirical phenomena. To deny this would be to deny scientific status to sociology, anthropology, and psychology. Sometimes one encounters such denials, but they need not be taken seriously, for they are obviously grounded on a very arbitrary and narrow definition of science.
