**The Senses.** Knowledge is the material on which the mind works. In every progressive life fresh knowledge must be gathered as the days go by. The senses of man are the gateways through which that knowledge enters. The senses of man must be developed, therefore, as completely as is possible. Seeing, hearing, tasting, smelling and feeling must all be developed fully and joyously for the pleasure and benefit of man. Without sharp senses, man may not have the highest earthly joy. **The Reasoning Power.** It is not sufficient for the contentment of man that he gather knowledge, and add fact to fact. All new information must be compared with other information, so that conclusions may be drawn, and new knowledge brought into view. By this process of reasoning, on the basis of acquired knowledge, man may rise by sure steps to a high degree of understanding. Man must train himself, with all his might, to use this wonderful faculty of reason, so that he may intelligently read new knowledge from all he learns. A fact, of itself, is lifeless; only when it is compared with other facts, does it leap into life, and show forth its hidden meaning. **The Feelings.** The sense of feeling is but a poor expression for the one great sense by which man may directly communicate with the region of the unseen. Through this sense, man stands on the border line between earth and the external universe. Those who have communion with the forces about them, because of their greater refinement of feeling, have comfort which is attainable in no other manner. Moreover, our feelings with respect to our fellow men should be cultivated. We must learn to sympathize with them in their distresses, rejoice with them in their joys, and pity them in their sins. The education of the feelings is a great duty of man. **The Spiritual Sense.** This sense is closely akin to the feelings. The virtues of man, such as hope, charity, and mercy, can reach high development only on the basis of the conviction that the unseen world may be known. When this conviction grows upon a man, and he reaches out for a fuller understanding of it, his spiritual sense develops, new worlds are opened to him and he conforms to the intelligent love which made the Great Plan possible.
