No particular stress is here laid on the term "faculty," as a designation of the moral power. There is, indeed, no validity in the claim of some recent psychologists that the term must be abandoned on the ground that psychology discovers only mental acts, without a psychic subject with distinct faculties back of the acts. Yet the term faculty has often been used and understood in a way inconsistent with the essential and conscious unity of the personal _ego_ or self, making the soul seem a bundle of independent and separately acting parts of a psychical organism. The perfect oneness of the personal self must be maintained, and the term faculty, when used for any form of psychical ability, must be understood simply as expressing the soul's capacity or power to do any specific form of work, or to act in any particular and distinctively definable way, as, for instance, to know, to feel, to will, to remember, to compare. In this sense the use of the term stands fully justified in psychological usage and propriety. But the reason for abating from the claim of strict exactness in the term in this connection is that the conscience, in its full conception and action, as will hereafter appear, while exhibiting a specific and simple power as its central reality, will be found to include also subordinately the conjoint action of several other forms of psychical power. It stands for a complex of capacities and powers. This will appear when we reach its analysis. But the question of the absolute simplicity of the faculty does not affect the substance of our inquiry into its existence nor the propriety of employing the term for the power in its totality. For, as naming the central and decisive reality in the conscience, it is justly spoken of as a special faculty. Even when it is viewed as standing for a complex of powers converging, in their functions, to the discernment of moral distinctions and the reality of duty, it has sufficient individuality to be rightly and scientifically designated in this way. The question to be considered, and upon which the logical conclusions of the science will depend, is not its absolute simplicity, but the fact of such a power as a normal part in the soul's essential constitution of powers. If the power be found integral and normal in the soul's actual capacities, we have all that is essential for the foundation of ethics.
