But I do not stop here. Nature is to engage our force of thought, not simply for the aid which the knowledge of it gives in working, but for a higher end. Nature should be studied for its own sake, because so wonderful a work of God, because impressed with his perfection, because radiant with beauty, and grandeur, and wisdom, and beneficence. A laborer, like every other man, is to be liberally educated, that is, he is to get knowledge, not only for his bodily subsistence, but for the life, and growth, and elevation of his mind. Am I asked, whether I expect the laborer to traverse the whole circle of the physical sciences? Certainly not; nor do I expect the merchant, or the lawyer, or preacher to do it. Nor is this at all necessary to elevation of soul. The truths of physical science, which give greatest dignity to the mind, are those general laws of the creation which it has required ages to unfold, but which an active mind, bent on self-enlargement, may so far study and comprehend, as to interpret the changes of nature perpetually taking place around us, as to see in all the forces of the universe the workings of one Infinite Power, and in all its arrangements the manifestation of one unsearchable wisdom. And this leads me to observe the second great object on which force of thought is to be exerted, and that is mind, spirit, comprehending under this word God and all his intelligent offspring. This is the subject of what are called the metaphysical and moral sciences. This is the grand field for thought; for the outward, material world is the shadow of the spiritual, and made to minister to it. This study is of vast extent. It comprehends theology, metaphysics, moral philosophy, political science, history, literature. This is a formidable list, and it may seem to include a vast amount of knowledge which is necessarily placed beyond the reach of the laborer. But it is an interesting thought, that the key to these various sciences is given to every human being in his own nature, so that they are peculiarly accessible to him. How is it that I get my ideas of God, of my fellow-creatures, of the deeds, suffering, motives, which make up universal history? I comprehend all these from the consciousness of what passes in my own soul. The mind within me is a type representative of all others, and therefore I can understand all. Whence come my conceptions of the intelligence, and justice, and goodness, and power of God? It is because my own spirit contains the germs of these attributes. The ideas of them are first derived from my own nature, and therefore I comprehend them in other beings. Thus the foundation of all the sciences which treat of mind is laid in every man's breast. The good man is exercising in his business and family faculties and affections which bear a likeness to the attributes of the Divinity, and to the energies which have made the greatest men illustrious; so that
