To know a thing is to be conscious of its relation to the mind. We know it, not in itself, but in and through this relation. Our knowledge of God, who is the absolute, is not absolute knowledge, but a knowledge of Him in so far as He is related to the mind of man. Since, however, mind is reason and not unreason, there is harmony between it and things, between it and God; and hence to be conscious of its relation to God and the universe is to be conscious of a real relation, in which both the thinker and his thought are in truth what they seem to be. The ultimate reality is inferred, not directly perceived. It reveals itself to the purest faith and love, and may be hidden from one who knows all the sciences. As man's relations to his fellows make him a social and political being, so his relations to the unseen power behind and within the visible world, of whose presence he is always, however dimly, conscious, and to whom he refers whatever touches the senses, as well as the principle of life itself, make him a religious being. In identifying what seem to be our particular interests with the interests of all, we make escape from narrowness and isolation into the general life of humanity; and when we come to understand that not only mankind but all nature is a Unity in the Consciousness of the Infinite and Eternal, bound together by thought and love, we enter into the glorious liberty of the Sons of God, and feel that nor height nor depth nor things past nor things to come shall separate us from the divine charity. We are akin to all that may become part of our life; and whatever we know or love or admire is spiritualized and made human. To understand the things of the spirit we must have spiritual experience. The intuitions of time and space, as well as the principle of causality, are given in the constitution of the mind. So is the idea of being, of perfection, of beauty, of eternity, of infinity, of duty. To think implies being, to perceive things as existing in time and space implies consciousness of eternity and infinity. To know the imperfect is possible only in the light of the perfect. Subject is itself object, the first known and best understood, and the laws of mind are laws of being. If the constitution of mind makes the revelation of the material world possible only under the forms of time and space, intelligible only as sequence of cause and effect, the reason is to be found in the nature of things. If the constitution of mind postulates one who knows and shapes, in a world in which whatever is, is intelligible, in which there is order, proportion, and purpose, it is because such an One is given in the nature of things, and He is God. However living our faith, it is faith and not knowledge; and should it become knowledge, it would cease to be faith. There are three kinds of authors,--those who impart knowledge, those who give delight, and those who strengthen and inspire.
