_Schelling and Hegel._--_Schelling_ develops the spiritual or ideal theory of beauty. _Hegel_ carries out this theory and makes a complete science of it, classifies and analyzes the arts. His work is regarded as the first complete discussion of the philosophy of the fine arts. It is characterized by strength, clearness, depth, power of analysis, richness of imagination. _Theory of Jouffroy._--_Jouffroy_, in France, among the later writers, has treated fully, and in an admirable manner, of the philosophy of the beautiful. His theory is derived from that of Hegel, with some modifications. It is essentially the theory last presented in the discussion of the subject in the preceding section, viz., the expression of the spiritual or invisible element under sensible forms. No writer is more worthy of study than Jouffroy. His work is clear, strong, and of admirable power of analysis. _Cousin._--Among the eclectics, _Cousin_, in his treatise on the true, the beautiful, and the good, has many just observations, with much beauty and philosophic clearness of expression. _McDermot._--In English, beside the works already referred to, must be noticed the treatise of _McDermot_ on Taste, in which the nature and objects of taste are fully and well discussed.
