I call _vulgar_ (common) all that does not speak to the mind, of which all the interest is addressed only to the senses. There are, no doubt, an infinite number of things vulgar in themselves from their material and subject. But as the vulgarity of the material can always be ennobled by the treatment, in respect of art the only question is that relating to the _vulgarity_ in form. A vulgar mind will dishonor the most noble matter by treating it in a common manner. A great and noble mind, on the contrary, will ennoble even a common matter, and it will do so by superadding to it something spiritual and discovering in it some aspect in which this matter has greatness. Thus, for example, a vulgar historian will relate to us the most insignificant actions of a hero with a scrupulousness as great as that bestowed on his sublimest exploit, and will dwell as lengthily on his pedigree, his costume, and his household as on his projects and his enterprises. He will relate those of his actions that have the most grandeur in such wise that no one will perceive that character in them. On the contrary, a historian of genius, himself endowed with nobleness of mind, will give even to the private life and the least considerable actions of his hero an interest and a value that will make them considerable. Thus, again, in the matter of the plastic arts, the Dutch and Flemish painters have given proof of a vulgar taste; the Italians, and still more the ancient Greeks, of a grand and noble taste. The Greeks always went to the ideal; they rejected every vulgar feature, and chose no common subject. A portrait painter can represent his model in a _common_ manner or with _grandeur;_ in a _common manner_ if he reproduce the merely _accidental_ details with the same care as the essential features, if he neglect the great to carry out the minutiæ curiously. He does it grandly if he know how to find out and place in relief what is most _interesting_, and distinguish the accidental from the necessary; if he be satisfied with indicating what is paltry, reserving all the finish of the execution for what is great. And the only thing that is great is the expression of the soul itself, manifesting itself by actions, gestures, or attitudes. The poet treats his subject in a common manner when in the execution of his theme he dwells on valueless facts and only skims rapidly over those that are important. He treats his theme with grandeur when he associates with it what is great. For example, Homer treated the shield of Achilles grandly, though the making of a shield, looking merely at the matter, is a very commonplace affair.
