For our purpose this morning, learning may be divided into four provinces: literature, history, science and philosophy, to which must be added in any complete topography of the realm, pure mathematics. By pure mathematics I mean arithmetic, algebra, geometry, logarithms, the calculus and the like. But pure mathematics is simply an instrument by which the scientific mind reaches certain results. I shall not therefore consider this department at all; it is not necessary for our purpose. Some one must look through the telescope, some one must know how to use the spectroscope in order to tell us what is the size of the sun and its constituent elements; but we do not need to examine the telescope or the spectroscope. Some one must be skilled in pure mathematics in order to tell us how many miles the sun is distant from our own earth, but we may take the result without going through the process. This instrument must always be left in the hand of the specialist. I wish to show you that all that is best, highest and most important in literature, history, science and philosophy lies within the power of your acquisition. I wish to show you the spirit with which you must study, and the purpose with which you must acquire it; and I wish to show you that if you acquire in that spirit and with that purpose you can not but gain in your religious nature. I. In the first place, then, what is literature, and why do we study it? Literature is the expression of human life, in its innermost experiences, and in its outward forms. Sometimes it is the expression of social life, sometimes of the intellectual life, sometimes of the emotional life; but always and everywhere literature is a mirror held up either before society or before the human heart; no, not a mirror, but the sensitized plate in a photographic apparatus; and the picture, now of society, now of the brain, now of the palpitating heart with its fears, hopes, joys and experiences, is given upon the plate; and literature is the picture brought out for us to examine. To study literature is not to study language. Language is merely the instrument which we use for the study of literature. To study literature is to study life—life in its outward semblance or life in its inward experiences. It is to study the life of the community and of society as we study it in Thackeray; or it is to study the life of the brain and the thought as we study it in Plato and Bacon; or it is to study the life of the inward emotions as we study it in Tennyson or Wordsworth. Now, in order to study life as it is portrayed in literature it is not necessary to know the original language in which that life was portrayed. Some one must have studied the Greek language in order to bring Homer to our intelligence; some one must have studied Latin and brought Horace within our horizon; some one must have studied French and brought Molière within our knowledge; some one must have studied
