It will be well to give further positive exposition of the meaning of the view thus stated. To return once more to our fundamental psychological conception, knowledge is essentially relevant to the solution of particular problems of more or less urgency and of various kinds and figures in the solution of such problems as the assemblage of consciously recognized symbols or stimuli by which various actions are suggested. The object as known is therefore not the same as the object as apprehended in other possible modes of being conscious of it. The workman who is actually using his tool in shaping his material, or the warrior who is actually using his weapon in the thick of combat, is, if conscious of these objects at all (and doubtless he may be conscious of them at such times), not conscious of them _as objects_--as the one might be, for example, in adjusting the tool for a particular kind of use, and the other in giving a keen edge to his blade. Under these latter circumstances the tool or weapon is an _object_, and its observed condition, viewed in the light of a purpose of using the object in a certain way, is regarded as properly suggesting certain changes or improvements. And likewise will the tool or the weapon have an objective character in the agent's apprehension in the moment of identifying and selecting it from among a number of others, or even in the act of reaching for it, especially if it is inconveniently placed. But in the act of freely using one's objective means the category of the objective plays no part in consciousness, because at such times there is no judgment respecting the means--because there is no sufficient occasion for the isolation of certain conscious elements from the rest of the stream of conscious experience to be defined as stimuli to certain needed responses. Such isolation will not normally take place so long as the reactions suggested by the conscious contents involved in the experience are fully adequate to the situation. Objects are not normally held apart as such from the stream of consciousness in which they are presented and recognized as possessing qualities warranting certain modes of conduct, excepting as it has become necessary to the attainment of the agent's purposes to modify or reconstruct his activity.[119]
