So likewise is it as truly impossible, for one intellectually and morally capable of appreciating problems of a more advanced and complex sort, to exploit the physical properties thus discovered until ethical determination of the end and economic determination of the means have been completed.[108] There are, then, we conclude, cases in which physical determination of the means is by itself not a sufficient preparation for conduct--in which there are ethical and economic problems which delay the application of the physical means to the end to which they may be physically adapted. Indeed, so much as this may well appear as sufficiently obvious without extended illustration. Everyone knows that it is nearly always necessary, in undertaking any work in which material things are used as means, to count the cost; and everyone knows likewise that not every end that is in any way attractive and within one's reach may without more ado be taken as an object of settled desire and effort. It is indeed needless to elaborate these commonplaces in the sense in which they are commonly understood. However, such is not our present purpose. Our purpose is the more specific one of showing that the meaning of Objectivity must be widened so as to include (1) the "universe" of ends in their ethical aspect and (2) the economic aspect of the means of action, as well as (3) the physical aspect to which the character of Objectivity is commonly restricted. We shall maintain that these are parts or phases of a complete conception of Reality, and that of them, consequently, Objectivity must be predicated for every essential reason connoted by such characterization of the world of things "external" to the senses. It has been with this conclusion in mind, then, that we have sought to emphasize the frequent serious inadequacy, for practical purposes, of the merely physical determination of the means in one's environment.
