Action with a purpose is deliberate; it involves a consciously foreseen end and a mental weighing of considerations pro and con. It also involves a conscious state of longing or desire for the end. The deliberate choice of an aim and of a settled disposition of desire takes time. During this time complete overt action is suspended. A person who does not have his mind made up, does not know what to do. Consequently he postpones definite action so far as possible. His position may be compared to that of man considering jumping across a ditch. If he were sure he could or could not make it, definite activity in some direction would occur. But if he considers, he is in doubt; he hesitates. During the time in which a single overt line of action is in suspense, his activities are confined to such redistributions of energy within the organism as will prepare a determinate course of action. He measures the ditch with his eyes; he brings himself taut to get a feel of the energy at his disposal; he looks about for other ways across, he reflects upon the importance of getting across. All this means an accentuation of consciousness; it means a turning in upon the individual's own attitudes, powers, wishes, etc.
Obviously, however, this surging up of personal factors into conscious recognition is a part of the whole activity in its temporal development. There is not first a purely psychical process, followed abruptly by a radically different physical one. There is one continuous behavior, proceeding from a more uncertain, divided, hesitating state to a more overt, determinate, or complete state. The activity at first consists mainly of certain tensions and adjustments within the organism; as these are coördinated into a unified attitude, the organism as a whole acts—some definite act is undertaken. We may distinguish, of course, the more explicitly conscious phase of the continuous activity as mental or psychical. But that only identifies the mental or psychical to mean the indeterminate, formative state of an activity which in its fullness involves putting forth of overt energy to modify the environment.
