‘We have still to examine whether sight produces any moral sentiment or intellectual faculty. It is a common opinion that the art of painting is the result of sight; and it is true that eyes are necessary to perceive colours, as the ears are to perceive sounds and tones; but the art of painting does not consist in the perception of colours, any more than music in the perception of sounds. Sight, therefore, and the faculty of painting are not at all in proportion. The sight of many animals is more perfect than that of man, but they do not know what painting is; and in mankind the talent of painting cannot be measured by the acuteness of sight. Great painters never attribute their talent to their eyes. They say, it is not the eye, but the understanding, which perceives the harmony of colours.’ Page 158. This is well put, and quite true; that is, it is the mind alone that perceives the relation and connexion between all our sensations. Thus the impression of the line bounding one side of the face does not perceive or compare itself with the impression of the line forming the other side of the face, but it is the mind or understanding (by means indeed of the eye) that perceives and compares the two impressions together. But neither will an _organ of painting_ answer this purpose, unless this separate organ includes a separate _mind_, with a complete workshop and set of offices to execute all the departments of judgment, taste, invention, &c. _i.e._ to compare, analyse, and combine its own particular sensations. But neither will this answer the end. For either all these must be included under one, and exhibit themselves in the same proportions wherever the organ exists, which is not the fact; or if they are distinct and independent of one another, then they cannot be expressed by any one organ. Dr. Spurzheim has, in a subsequent part of his work, provided for this objection, and divided the _Organ of Sight_ into five or six subdivisions; such as, the _Organ of Form_, the _Organ of Colour_, the _Organ of Weight_, the _Organ of Space_, and God knows how many more. This is evading and at the same time increasing the difficulty. Thus. The best draughtsmen are not observed to be always the best colourists, Raphael and Titian for example. There must therefore be a new division of the _Organ of Sight_ into (at least) the two divisions of Form and Colour. Now it is not to be supposed that these organs are thus separated merely for separation’s sake, but that there is something in the quality or texture of the substance of the brain in each organ, peculiarly fitted for each different sort of impression, and by an excess of quantity producing an excess of faculty. The _size_ alone of the organ cannot account for the difference of the faculty, without this other condition of quality annexed. Suppose the distinguishing quality of the _organ of form_ to be a certain tenaciousness; that of the _organ
