induced and intentional practical division of labor; as relative assignments of position with reference to performance of a task; as deliberate distribution of forces at command for their more economic use. The interaction of bald fact and hypothetical idea into the outcome of a single world of scientific apprehension and comprehension is but the successful achieving of the aim on account of which the distinctions in question were instituted.
Thus we come back to the problem of logical theory. To take the distinctions of thought and fact, etc., as ontological, as inherently fixed in the make-up of the structure of being, is to treat the actual development of scientific inquiry and scientific control as a mere subsidiary topic ultimately of only utilitarian worth. It is also to state the terms upon which thought and being transact business in a way so totally alien to the use made of these distinctions in concrete experience as to create a problem which can be discussed only in terms of itself—not in terms of the conduct of life—metaphysics again in the bad sense of that term. As against this, the problem of a logic which aligns itself with the origin and employ of reflective thought in everyday life and in critical science, is to follow the natural history of thinking as a life-process having its own generating antecedents and stimuli, its own states and career, and its own specific objective or limit.
This point of view makes it possible for logical theory to come to terms with psychology.2 When logic is considered as having to do with the wholesale activity of thought per se, the question of the historic process by which this or that particular thought came to be, of how its object happens to present itself as sensation, or perception, or conception, is quite irrelevant. These things are mere temporal accidents. The psychologist (not lifting his gaze from the realm of the changeable) may find in them matters of interest. His whole industry is just with natural history—to trace series of psychical events as they mutually excite and inhibit one another. But the logician, we are told, has a deeper problem and an outlook of more unbounded horizon. He deals with the question of the eternal nature of thought and its eternal validity in relation to an eternal reality. He is concerned, not with genesis, but with value, not with a historic cycle, but with absolute distinctions and relations.
Still the query haunts us: Is this so in truth? Or has the logician of a certain type arbitrarily made it thus by taking his terms apart from reference to the specific occasions in which they arise and situations in which they function? If the latter, then the very denial of historic relationship and of the significance of historic method, is indicative only of the unreal character of his own abstraction. It means in effect that the affairs under consideration have been isolated from the conditions in which alone they have determinable meaning and assignable worth. It is astonishing that, in the face of the advance of the evolutionary method in natural science, any logician can persist in the assertion of a rigid difference between the problem of origin and of nature; between genesis and analysis; between history and validity. Such assertion simply reiterates as final a distinction which grew up and had meaning in pre-evolutionary science. It asserts against the most marked advance which scientific method has yet made a survival of a crude period of logical scientific procedure. We have no choice save either to conceive of thinking as a response to a specific stimulus, or else to regard it as something "in itself," having just in and of itself certain traits, elements, and laws. If we give up the last view, we must take the former.
The entire significance of the evolutionary method in biology and social history is that every distinct organ, structure, or formation, every grouping of cells or elements, has to be treated as an instrument of adjustment or adaptation to a particular environing situation. Its meaning, its character, its value, is known when, and only when, it is considered as an arrangement for meeting the conditions involved in some specific situation. This analysis of value is carried out in detail by tracing successive stages of development—by endeavoring to locate the particular situation in which each structure has its origin, and by tracing the successive modifications through which, in response to changing media, it has reached its present conformation.3 To persist in condemning natural history from the standpoint of what natural history meant before it identified itself with an evolutionary process is not so much to exclude the natural-history standpoint from philosophic consideration as it is to evince ignorance of what it signifies.
Psychology as the natural history of the various attitudes and structures through which experiencing passes, as an account of the conditions under which this or that state emerges, and of the way in which it influences, by stimulation or inhibition, production of other states or conformations of consciousness, is indispensable to logical evaluation, the moment we treat logical theory as an account of thinking as a mode of adaptation to its own generating conditions, and judge its validity by reference to its efficiency in meeting its problems. The historical point of view describes the sequence; the normative follows the sequence to its conclusion, and then turns back and judges each historical step by viewing it in reference to its own outcome.4
In the course of changing experience we keep our balance as we move from situations of an affectional quality to those which are practical or appreciative or reflective, because we bear constantly in mind the context in which any particular distinction presents itself. As we submit each characteristic function and situation of experience to our gaze, we find it has a dual aspect. Wherever there is striving there are obstacles; wherever there is affection there are persons who are attached; wherever there is doing there is accomplishment; wherever there is appreciation there is value; wherever there is thinking there is material-in-question. We keep our footing as we move from one attitude to another, from one characteristic quality to another, because we know the position occupied in the whole growth by the particular function in which we are engaged, and the position within the function of the particular element that engages us.
The distinction between each attitude and function and its predecessor and successor is serial, dynamic, operative. The distinctions within any given operation or function are structural, contemporaneous, and distributive. Thinking follows, we will say, striving, and doing follows thinking. Each in the fulfilment of its own function inevitably calls out its successor. But coincident, simultaneous, and correspondent within doing, is the distinction of doer and of deed; within the function of thought, of thinking and material thought upon; within the function of striving, of obstacle of aim, of means and end. We keep our paths straight because we do not confuse the sequential, efficient, and functional relationship of types of experience with the contemporaneous, correlative, and structural distinctions of elements within a given function. In the seeming maze of endless confusion and unlimited shiftings, we find our way by the means of the stimulations and checks occurring within the process we are actually engaged with. We do not contrast or confuse a condition or state which is an element in the formation of one operation with the status or element which is one of the distributive terms of another function. If we do, we have at once an insoluble, because meaningless, problem upon our hands.
Now the epistemological logician deliberately shuts himself off from those cues and checks upon which the plain man instinctively relies, and which the scientific man deliberately searches for and adopts as constituting his technique. Consequently he is likely to set the sort of object or material which has place and significance only in one of the serial functional situations of experience, over against the active attitude which describes part of the structural constitution of another situation; or with equal lack of justification to assimilate terms characteristic of different stages to one another. He sets the agent, as he is found in the intimacy of love or appreciation, over against the externality of the fact, as that is defined within the reflective process. He takes the material which thought selects as its own basis for further procedure to be identical with the significant content which it secures for itself in the successful pursuit of its aim; and this in turn he regards as the material which was presented at the outset, and whose peculiarities were the express means of awakening thought. He identifies the final deposit of the thought-function with its own generating antecedent, and then disposes of the resulting surd by reference to some metaphysical consideration, which remains when logical inquiry, when science (as interpreted by him), has done its work. He does this, not because he prefers confusion to order,
