subjects, are really less reliable, because more likely to be founded on too superficial observations. The man of more science, and yet slower progress, is expected to handle the more difficult problems, and subject all their elements to a sharper scrutiny. LANGUAGE Is intimately connected with thought, not only as its expression, but as an auxiliary. Thoughts always become clearer and more firmly fixed in the mind by being expressed. Though words are not thoughts, and, carelessly uttered, may be quite meaningless, thoughts not only seek to embody, or clothe themselves in language, but our best thinking is done in the use of words, uttered or unexpressed. Though there may be no sound for the ear nor symbol for the eye, the word inly spoken serves to fix the otherwise transient thought so that it can be afterward recalled, and perhaps uttered, to stimulate the thinking of others. Hence the importance of the study of language, of words and their syntax, as employed to express mental processes. Grammar is important as an intellectual science. ÆSTHETICS. The science of the beautiful is an important and delightful branch of study; the knowledge gained being mostly through immediate perceptions and sensible impressions. Beauty, wherever discovered, appeals to the sensibilities, and raises pleasant emotions. As a means of culture it elevates and refines. Communings with nature in her lovelier moods subdue asperities, and inspire gentle, kindly dispositions, while the beautiful creations of architecture, statuary, and painting, of poetry and music, fill the souls of discerning, susceptible persons with indescribable pleasure. But though such emotions are frequently excited, and seem familiar, they are of all our mental phenomena least understood, and most difficult to analyze. Some of our most common experiences are, on examination, found the most inexplicable. All, in a general way, know that beauty of form, proportion and color, wherever seen, excites pleasurable emotions. But our knowledge of sensations and emotions is generally, though direct and immediate, imperfect, and can become thorough only when the first impression is retained, and the higher faculties employed in studying its character and its cause. Dr. Porter’s[2] chapters on “Sense Perceptions” are, on the whole, satisfactory, and will help advance this branch of knowledge toward the dignity of a science. They give an analysis of beauty in objects that address the senses, and also of the emotions it awakens. Thoughtful students confess their need of more help. The science has its charms, but is still in its adolescence. Some things elementary are yet wanting, or known only by the names given them. Men talk of the “line of beauty” in architecture and sculpture, but do not yet know just what it is, or by what peculiarities it works on the sympathies of the beholder. We feel the exquisite pleasure but do not know just wherein the charms
