 which they “come together,” the form of their connexion or union into a social will. This form presupposes the existence of two or more free persons, i.e. persons who allow themselves to be determined by their own wish to remain strangers or to come together. The given matter, i.e. the conceptually simplest content of the compact, is the exchange of things. Here two wills, which were before opposed, each wishing to attach the greatest value to his things, unite in agreeing that two things shall be of the same value, or where the expression of value in one commodity is customary, that a given thing shall be worth so much, i.e., shall be equal in value to so many units of the standard of value, whether this value outlasts the act of exchange or not. But in the same way any number of wills may agree upon a standard or norm of value, even though the “how much” value of particular things must be left, either to the comparison, or more exactly to the measurement, of one or more persons, or indeed to manifold agreements. (The Greek language denotes such union best as “composition” ξυνθήκη—here the common will arises, as it were visibly, through the fact that several furnish thereto a contribution of their own will; and this can only take place by their “explaining” their will, i.e. making it known by signs. Such a sign may be the transference of a thing; but as an abbreviation, a spoken sentence, or finally a word may suffice. And it is only in words that the present will of a future will—a promise—can be expressed. Only in words again can an order, in general a proposition containing something willed for a time extending beyond the moment, be expressed. But such a one is the proposition about the value of signs, hence possibly also about the meaning of words. The Imperative concerning it either remains without expression, or it expresses itself in words). Measures, weights and coins, again, are signs, that is, signs of a covenanted or otherwise established unit of measurement, or of a compound of such, which certainly exists primarily only in thought.

49. Conventional signs between two or more are a matter known to every one. They are characterised by the fact that they may depart to any extent from the nature of natural signs and as a rule do so depart, more than signs of which the meaning is based upon the naturally growing social will. For instance, a stamp placed askew upon the envelope or a yellow rose in the button-hole, has not the slightest similarity or other relationship with the announcement “This afternoon at five, rendezvous in the confectioner’s shop”; and yet both may serve the purpose of such an announcement
