According to this principle, the arts marshal themselves, and succeed one another, to form a regular and complete system, thus: 1. First _Architecture_ presents itself. This art, in fact, is incapable of representing an idea otherwise than in a vague, indeterminate manner. It fashions the masses of inorganic nature, according to the laws of matter and geometrical proportions; it disposes them with regularity and symmetry in such a manner as to offer to the eyes an image which is a simple reflex of the spirit, a dumb symbol of the thought. Architecture is at the same time appropriated to ends which are foreign to it: it is destined to furnish a dwelling for man and a temple for Divinity; it must shelter under its roof, in its enclosure, the other arts, and, in particular, sculpture and painting. For these reasons architecture should, historically and logically, be placed first in the series of the arts. 2. In a higher rank is Sculpture, which already exhibits spirit under certain determinate traits. Its object, in fact, is spirit individualized, revealed by the human form and its living organism. Under this visible appearance, by the features of the countenance, and the proportions of the body, it expresses ideal beauty, divine calmness, serenity—in a word, the classic ideal. 3. Although retained in the world of visible forms, Painting offers a higher degree of spirituality. To form, it adds the different phases of visible appearance, the illusions of perspective, color, light and shades, and thereby it becomes capable, not only of reproducing the various pictures of nature, but also of expressing upon canvas the most profound sentiments of the human soul, and all the scenes of ethical life. 4. But, as an expression of sentiment, _Music_ still surpasses painting. What it expresses is the soul itself, in its most intimate and profound relations; and this by a sensuous phenomenon, equally invisible, instantaneous, intangible—sound—sonorous vibrations, which resound in the abysses of the soul, and agitate it throughout. 5. All these arts culminate in Poetry, which includes them and surpasses them, and whose superiority is due to its mode of expression—_speech_. It alone is capable of expressing all ideas, all sentiments, all passions, the highest conceptions of the intelligence, and the most fugitive impressions of the soul. To it alone is given to represent an action in its complete development and in all its phases. It is the universal art—its domain is unlimited. Hence it is divided into many species, of which the principal are _epic_, _lyric_ and _dramatic_ poetry.
