In answering this amended form of the objection it is entirely unnecessary to discuss the issue of fact which it has raised as to whether or not complete description of a physical object or event is a practical or theoretical possibility. It need only be pointed out that at best such complete description can only be successful in its purpose on condition that the individual upon whom the experiment is tried be willing to attend and have the requisite "apperceptive background." The accuracy with which another person's knowledge shall copy the knowledge which I endeavor to impart to him must manifestly depend upon these two leading conditions, not to mention also the measure of my own pedagogical and literary skill. Any consideration of such a purely psychological problem as is here suggested would be entirely out of place in a discussion the purpose of which is not that of analyzing the process of judgment, but that of interpreting its meaning aspects. Let us grant the entire psychological possibility of making socially current in the manner here suggested the most highly individual and concrete cognition of an object one may please, and let us grant, moreover, that this possibility has been actually realized. This concurrent testimony of the witness will doubtless confirm one's impression of the accuracy of the process of observation and inference whereby the knowledge which has been imparted was first gained, but we must deny that it can do more than this. For indeed, apart from some independent self-reliant conviction of the objective validity of the knowledge in question, how should another's assent be taken as _confirmation_ and not rather as evidence of one's own mere skill in suggestion and of the other's susceptibility thereto? We must deny that even in the improved form the criterion of social currency is a valid one. In a word, the social currency of knowledge to the extent to which it can exist requires as its condition, and is evidence of, the equal social currency of certain interests, purposes, or points of view for predication; and if it be possible to make socially current an item of concrete knowledge, with all its concrete fulness of detail, then _a fortiori_ it must be possible to make socially current the concrete individual purpose with reference to which this item of knowledge first of all took form. Whether such a thing be psychologically possible at all the reader may decide; but if it be possible in the sphere of knowledge of fact, then it must be possible in the sphere of valuation. In short, judgment in either field, in definition of a certain object or commodity or moral act as, for the agent, an objective fact possessing certain characters, involves the tacit assumption of social verifiability as a matter of course; but it does not rest upon this assumption, nor is this assumption the essence of its meaning. To say that my judgment is socially verifiable, that my concrete object of perception or of
