in studying himself, in learning the highest principles and laws of his own soul, he is in truth studying God, studying all human history, studying the philosophy which has immortalized the sages of ancient and modern times. In every man's mind and life all other minds and lives are more or less represented and wrapped up. To study other things, I must go into the outward world, and perhaps go far. To study the science of spirit, I must come home and enter my own soul. The profoundest books that have ever been written do nothing more than bring out, place in clear light, what is passing in each of your minds. So near you, so within you, is the grandest truth. I have, indeed, no expectation that the laborer is to understand in detail the various sciences which relate to mind. Few men in any vocation do so understand them. Nor is it necessary; though, where time can be commanded, the thorough study of some particular branch, in which the individual has a special interest, will be found of great utility. What is needed to elevate the soul is, not that a man should know all that has been thought and written in regard to the spiritual nature, not that a man should become an encyclopaedia, but that the great ideas, in which all discoveries terminate, which sum up all sciences, which the philosopher extracts from infinite details, may be comprehended and felt. It is not the quantity but the quality of knowledge which determines the mind's dignity. A man of immense information may, through the want of large and comprehensive ideas, be far inferior in intellect to a laborer, who, with little knowledge, has yet seized on great truths. For example, I do not expect the laborer to study theology in the ancient languages, in the writings of the Fathers, in the history of sects, &c., &c.; nor is this needful. All theology, scattered as it is through countless volumes, is summed up in the idea of God; and let this idea shine bright and clear in the laborer's soul and he has the essence of theological libraries, and a far higher light than has visited thousands of renowned divines. A great mind is formed by a few great ideas, not by an infinity of loose details. I have known very learned men who seemed to me very poor in intellect, because they had no grand thoughts. What avails it that a man has studied ever so minutely the histories of Greece and Rome, if the great ideas of freedom, and beauty, and valor, and spiritual energy, have not been kindled by these records into living fires in his soul? The illumination of an age does not consist in the amount of its knowledge, but in the broad and noble principles of which that knowledge is the foundation and inspirer. The truth is, that the most laborious and successful student is confined in his researches to a very few of God's works; but this limited knowledge of things may still suggest universal laws, broad principles, grand ideas, and these elevate the mind.
