[98] I have before me Professor A. Graziadei's article Intorno alla teoria edonistica del valore. (In Riforma Sociale, September 15th, 1900); in which A. fails to see how the purist theory of value dovetails in with the doctrines of Psychophysics and Psychology. I can well believe it! Psychophysics and Psychology are natural sciences and cannot throw light on economic fact which is mental and of value. I may be allowed to point out, that, even three years ago, I gave a warning against the confusion of economics with psychology. (See in this volume pp. 72-75.) He who appeals to psychology (naturalistic) in order to understand economic fact, will always meet with the delusion, opportunely shown up by Graziadei. I have stated the reasons owing to which economics cannot dwell where the psychologists and hedonists say; now Graziedei has questioned the door-keepers (Fechner, Wundt, etc.), and has learnt that it does not dwell there. Well and good!
[99] Camillo Trivero, La teoria dei bisogni, Turin, Bocca, 1900, pp. 198. Trivero means by need 'the condition of a being, either conscious or unconscious (man, animal, plant, thing), in which it cannot remain': so that it can be said 'that all needs are ultimately condensed into the supreme need or end of being or becoming.' Need for him is hence actual reality itself. But since, on the other hand, he declares that he does not wish to solve nor even to consider the philosophical problem, it is hard to understand what a theory of needs (i.e. of reality) can be, and for what reason he goes back to such generalities.
It is true that Trivero believes that, by going back to the general concept of need, he can establish the parent theory on which rest the particular doctrines of needs; and amongst them economics, which concerns itself with economic needs. If there are species—he says—we ought to determine of what genus they are species. But he will allow me to remark that the genus to look for is, as logic teaches, the proximate genus. To jump to such a great distance as to reality or to fact, would only lead to the noble discovery: that economic needs are part of reality, are a group of facts.
And what he does is to make an equally valuable discovery: that the true theory of history is the theory of needs, which, granted his definition of needs, is as much as to say that history is history of reality and the theory of it is—the theory.
