We are here face to face with a crucial point in analytic realism. Realism argues that we have no alternative except either to regard analysis as falsifying (à la Bergson), and thus commit ourselves to distrust of science as an organ of knowledge, or else to admit that something eulogistically termed Reality (especially as _Existence_, Being as subject to space and time determinations) is but a complex made up of fixed, mutually independent simples: viz., that Reality is truly conceived only under the caption of whole and parts, where the parts are independent of each other and consequently of the whole. For instrumentalism, however, the alleged dilemma simply does not exist. The results of abstraction and analysis are perfectly real; but they are real, like everything else, _where_ they are real: that is to say, in some _particular_ _co_existence in the situation where they originate and operate. The remark is perhaps more cryptic than enlightening. Its intent is that reflection is an actual occurrence as much so as a thunderstorm or a growing plant, and as an actual existence it is characterized by specific existential traits uniquely belonging to it: the entities of simple data as such. It is in control of the evidential function that irreducible and independent simples or elements exist. They certainly are found there; as we have seen they _are_ "common-sense" objects broken up into expeditious and unambiguous signs of conclusions to be drawn, conclusions about other things with which they--the elements--are continuous in some respects, although discrete[4] with respect to their sensory conditions. But there is no more reason for supposing that they exist _elsewhere_ in the same manner than there is for supposing that centaurs coexist along with domestic horses and cows because they coexist with the material of folk-tales or rites, or for supposing that pigs of iron pre-existed as pigs in the mine. There is no falsifying in analysis _because_ the analysis is carried on within a situation which controls it. The fallacy and falsifying is on the part of the philosopher who ignores the contextual situation and who transfers the properties which things have as dependable evidential signs over to things in other modes of behavior.
