hedonistic calculation. They are explained away as being aberrations due to oversight or lapse of memory on the part of business men, or to some failure of logic or insight. Or they are construed and interpreted into the rationalistic terms of the hedonistic calculus by resort to an ambiguous use of the hedonistic concepts. So that the whole "money economy," with all the machinery of credit and the rest, disappears in a tissue of metaphors to reappear theoretically expurgated, sterilized, and simplified into a "refined system of barter," culminating in a net aggregate maximum of pleasurable sensations of consumption. But since it is in just this unhedonistic, unrationalistic pecuniary traffic that the tissue of business life consists; since it is this peculiar conventionalism of aims and standards that differentiates the life of the modern business community from any conceivable earlier or cruder phase of economic life; since it is in this tissue of pecuniary intercourse and pecuniary concepts, ideals, expedients, and aspirations that the conjunctures of business life arise and run their course of felicity and devastation; since it is here that those institutional changes take place which distinguish one phase or era of the business community's life from any other; since the growth and change of these habitual, conventional elements make the growth and character of any business era or business community; any theory of business which sets these elements aside or explains them away misses the main facts which it has gone out to seek. Life and its conjunctures and institutions being of this complexion, however much that state of the case may be deprecated, a theoretical account of the phenomena of this life must be drawn in these terms in which the phenomena occur. It is not simply that the hedonistic interpretation of modern economic phenomena is inadequate or misleading; if the phenomena are subjected to the hedonistic interpretation in the theoretical analysis they disappear from the theory; and if they would bear the interpretation in fact they would disappear in fact. If, in fact, all the conventional relations and principles of pecuniary intercourse were subject to such a perpetual rationalized, calculating revision, so that each article of usage, appreciation, or procedure must approve itself _de novo_ on hedonistic grounds of sensuous expediency to all concerned at every move, it is not conceivable that the institutional fabric would last over night.
