On the other side we have the facts of internal experience--the consciousness of effort, the sense of power and freedom, the idea of right and wrong, the feeling of dependence, of duty, and of obligation, the consciousness of moral responsibility and of moral desert, and the anticipation of a future retribution. These to our reason are the revelation of a righteous Lawgiver and Ruler who is over us; by whom we are obliged, and to whom we must account. This is the theoretic basis and necessary presupposition of all religion. And now speculative philosophy steps in and endeavors to reduce these concepts of science and religion to an ultimate unity. It endeavors to construe in thought the nature of that relation between the force manifested in nature and the moral Ruler revealed in conscience. Therefore it asks the questions, What is force? What is life? What is mind? If we say that force is as inherent and essential to matter as extension and inertia are, and that life and mind are but modes of force, we are on the high-road to mechanical Deism, if not _material Atheism_. If we say that matter is itself only a function of force, and that force is the ultimate of all ultimates, then the distinction between finite existence and the infinite Being is a merely verbal distinction, and we must yield to the seductions of _Pantheism_, which under this aspect of it is but another name for Atheism. But if we say that Spirit is the originator and matter the recipient of force, or "the recipient of impulse and energy," and that the immanent God is the life of all nature, we are pure _Theists_. We have now a "workable theory" by which we can satisfactorily interpret the universe.
