In our epoch of exact science and profound insight into phenomena and things, it is no longer possible to err on the very basis of a question of an interest so general and so vital as this relating to the monetary system. The suppression of such a defective instrument as money and its substitution by a mere simple writing down of transactions, but legally guaranteed,--a system which we have entitled «Social Comptabilism» demands the study of every economist who wishes progress independently of any dogma, doctrine or party. The time is at hand in which by the force of circumstances it must be carried into effect in highly civilized countries. Germany, almost entirely educated to-day, should have no reason to oppose its adoption, if she saw clearly the advantages which social comptabilism presents and the difficulties and inconveniences which would disappear on its use. It would be a great error to imagine that any kind of economic revolution is necessary to establish it. In Belgium M. De Greef[D], in his «_Essais sur la monnaie, le crédit et les banques_», has shown how simple, logical and profitable it would be to approach it by rapid strides resting on the fundamental principle of «social comptabilism»,--the guarantee of property. M. H. Denis[E] in his work on the «_Organisation et le Fonctionnement du service des chèques et des virements à la Caisse d'Epargne postale de l'Empire d'Autriche_», shows how such comptabilism has been already approached in what chiefly relates to deferred payments, in a great country, which although it does not generally lead the way in progress, seems to have correctly apprehended what relates to the machinery money masks and wrongly represents. We shall only add one more observation in justification of the way we look at the matter, it is that in our country there is in principle at the present time in the financial organisms patronised and guaranteed by the State, all that is needed to realize «social comptabilism». Does not the National Bank of Belgium, as well as the Bank of France, among our neighbours to the west, issue bank notes,--and from our point of view, these notes represent unities of comptabilist value--to all those who offer them sufficient guarantees. In exchange for a deposit of securities, or for well known signatures, paper is obtained, notes equivalent to metal money:--this is already on the road to social comptabilism. In place of that, let these banks issue notes, counters--only possible to be used once--or rather bankbooks containing leaves or fractions of leaves, or squares having a meaning equivalent to that of notes or counters, or able in some way easily to realize that meaning, and which would be simply obliterated in case of transactions accomplished and the working of comptabilism is fully seen although only at the threshold of the system.
