Chapter IV.—Of the Relative Importance of Truths:—Secondly, that Rare Truths are more important than Frequent Ones.
| [§ 1.] | No accidental violation of nature's principles should be represented. | [64] |
| [§ 2.] | But the cases in which those principles have been strikingly exemplified. | [65] |
| [§ 3.] | Which are comparatively rare. | [65] |
| [§ 4.] | All repetition is blamable. | [65] |
| [§ 5.] | The duty of the painter is the same as that of a preacher. | [66] |
Chapter V.—Of the Relative Importance of Truths:—Thirdly, that Truths of Color are the least important of all Truths.
| [§ 1.] | Difference between primary and secondary qualities in bodies. | [67] |
| [§ 2.] | The first are fully characteristic, the second imperfectly so. | [67] |
| [§ 3.] | Color is a secondary quality, therefore less important than form. | [68] |
| [§ 4.] | Color no distinction between objects of the same species. | [68] |
| [§ 5.] | And different in association from what it is alone. | [69] |
| [§ 6.] | It is not certain whether any two people see the same colors in things. | [69] |
| [§ 7.] | Form, considered as an element of landscape, includes light and shade. | [69] |
| [§ 8.] | Importance of light and shade in expressing the character of bodies, and unimportance of color. | [70] |
| [§ 9.] | Recapitulation. | [71] |
Chapter VI.—Recapitulation.
| [§ 1.] | The importance of historical truths. | [72] |
| [§ 2.] | Form, as explained by light and shade, the first of all truths. Tone, light, and color, are secondary. | [72] |
| [§ 3.] | And deceptive chiaroscuro the lowest of all. | [73] |
