Upon the ethical side, as has been intimated, the matter at issue concerns the nature of conscience. Conscience has been asserted by orthodox moralists to be unique in origin and subject-matter. The same view is embodied by implication in all those popular methods of moral training which attempt to fix rigid authoritative notions of right and wrong by disconnecting moral judgments from the aids and tests which are used in other forms of knowledge. Thus it has been asserted that conscience is an original faculty of illumination which (if it has not been dimmed by indulgence in sin) shines upon moral truths and objects and reveals them without effort for precisely what they are. Those who hold this view differ enormously among themselves as to the nature of the objects of conscience. Some hold them to be general principles, others individual acts, others the order of worth among motives, others the sense of duty in general, others the unqualified authority of right. Still others carry the implied logic of authority to conclusion, and identify knowledge of moral truths with a divine supernatural revelation of a code of commandments.
But among these diversities there is agreement about one fundamental. There must be a separate non-natural faculty of moral knowledge because the things to be known, the matters of right and wrong, good and evil, obligation and responsibility, form a separate domain, separate that is from that of ordinary action in its usual human and social significance. The latter activities may be prudential, political, scientific, economic. But, from the standpoint of these theories, they have no moral meaning until they are brought under the purview of this separate unique department of our nature. It thus turns out that the so-called intuitional theories of moral knowledge concentrate in themselves all the ideas which are subject to criticism in these pages: Namely, the assertion that morality is distinct in origin, working and destiny from the natural structure and career of human nature. This fact is the excuse, if excuse be desired, for a seemingly technical excursion that links intellectual activity with the conjoint operation of habit and impulse.

The Nature of Deliberation
So far the discussion has ignored the fact that there is an influential school of moralists (best represented in contemporary thought by the utilitarians) which also insists upon the natural, empirical character of moral judgments and beliefs. But unfortunately this school has followed a false psychology; and has tended, by calling out a reaction, actually to strengthen the hands of those who persist in assigning to morals a separate domain of action and in demanding a separate agent of moral knowledge. The essentials of this false psychology consist in two traits. The first, that knowledge originates from sensations (instead of from habits and impulses); and the second, that judgment about good and evil in action consists in calculation of agreeable and disagreeable consequences, of profit and loss. It is not surprising that this view seems to many to degrade morals, as well as to be false to facts. If the logical outcome of an empirical view of moral knowledge is that all morality is concerned with calculating what is expedient, politic, prudent, measured by consequences in the ways of pleasurable and painful sensations, then, say moralists of the orthodox school, we will have naught to do with such a sordid view: It is a reduction to the absurd of its premises. We will have a separate department for morals and a separate organ of moral knowledge.
Our first problem is then to investigate the nature of ordinary judgments upon what it is best or wise to do, or, in ordinary language, the nature of deliberation. We begin with a summary assertion that deliberation is a dramatic rehearsal (in imagination) of various competing possible lines of action. It starts from the blocking of efficient overt action, due to that conflict of prior habit and newly released impulse to which reference has been made. Then each habit, each impulse, involved in the temporary suspense of overt action takes its turn in being tried out. Deliberation is an experiment in finding out what the various lines of possible action are really like. It is an experiment in making various combinations of selected elements of habits and impulses, to see what the resultant action would be like if it were entered upon. But the trial is in imagination, not in overt fact. The experiment is carried on by tentative rehearsals in thought which do not affect physical facts outside the body. Thought runs ahead and foresees outcomes, and thereby avoids having to await the instruction of actual failure and disaster. An act overtly tried out is irrevocable, its consequences cannot be blotted out. An act tried out in imagination is not final or fatal. It is retrievable.
Each conflicting habit and impulse takes its turn in projecting itself upon the screen of imagination. It unrolls a picture of its future history, of the career it would have if it were given head. Although overt exhibition is checked by the pressure of contrary propulsive tendencies, this very inhibition gives habit a chance at manifestation in thought. Deliberation means precisely that activity is disintegrated, and that its various elements hold one another up. While none has force enough to become the center of a redirected activity, or to dominate a course of action, each has enough power to check others from exercising mastery. Activity does not cease in order to
