Now there is not the slightest reason to believe that animals have any idea of qualities, as such. Even the taste for the beautiful, which Mr. Darwin tells us is not unknown to various animals—especially birds, has relation to the object which attracts by its colour, &c., and not to the colour itself. But it is just this perception of the qualities of objects which is at the foundation, and forms the starting point, of all human progress. The essential instrument of intellectual development, articulate language, was first prompted by such a perception, and it was in the recognition of the qualities of actions, by reflection on their consequences, that the moral sense was gradually evolved. It can hardly be that a power which has had so wonderful an effect, and one which is so different from anything met with among the lower animals, can be referred to any of the ordinary faculties which these possess. If not, we must ascribe it to a new faculty altogether, a kind of spiritual insight, which can be explained only as resulting from the addition of a principle of activity superior to that which is the seat of the animal life. If we were to trace the beginning of every single branch of human culture, it would be found to have originated in the exercise of such a faculty of reflection as that here described. The elements of knowledge man possesses in common with the animals around him; but these have not built up any superstructure, because they have no spiritual insight such as will enable them to analyse those elements, and thus to fit them for re-combination into that wonderful series of forms which they have taken in the human mind.
