But here, again, he attains an imperfect felicity; he encounters limits and obstacles which he cannot surmount, and against which, his will is broken. He cannot obtain the perfect realization of his ideas, nor attain the ideal which his spirit conceives and toward which it aspires. He then feels the necessity of elevating himself to a higher sphere where all contradictions are cancelled; where the idea of the good and of happiness in their perfect accord and their enduring harmony is realized. This profound want of the soul is satisfied in three ways: in _art_, in _religion_, and in _philosophy_. The function of art is to lead us to the contemplation of the true, the infinite, under sensuous forms; for the beautiful is the unity, the realized harmony of two principles of existence, of the idea and the form, of the infinite and the finite. This is the principle and the hidden essence of things, beaming through their visible form. Art presents us, in its works, the image of this happy accord where all opposition ceases, and where all contradiction is cancelled. Such is the aim of art: to represent the divine, the infinite, under sensuous forms. This is its mission; it has no other and this it alone can fulfil. By this title it takes its place by the side of religion, and preserves its independence. It takes its rank also with philosophy, whose object is the knowledge of the true, of absolute truth. Alike then as to their general ground and aims, these three spheres are distinguished by the form under which they become revealed to the spirit and consciousness of man. Art is addressed to sensuous perception and to the imagination; religion is addressed to the soul, to the conscience, and to sentiment; philosophy is addressed to pure thought or to the reason, which conceives the truth in an abstract manner. Art, which offers us truth under sensuous forms, does not, however, respond to the profoundest needs of the soul. The spirit is possessed of the desire of entering into itself, of contemplating the truth in the inner recesses of consciousness. Above the domain of art, then, religion is placed, which reveals the infinite, and by meditation conveys to the depths of the heart, to the centre of the soul, that which in art we contemplate externally. As to philosophy, its peculiar aim is to conceive and to comprehend, by the intellect alone, under an abstract form, that which is given as sentiment or as sensuous representation.
