Doubtless the nobler species of animals possess not only sense-perception, but a considerable degree of the power of representation. They are not only able to recollect, but to imagine or fancy to some extent, as is evidenced by their dreams. But that animals do not generalize sufficiently to form for themselves a new objective world of types and general concepts, we have a sufficient evidence in the fact that they do not use words, or invent conventional symbols. With the activity of the symbol-making form of representation, which we have named Memory, and whose evidence is the invention and use of language, the true form of individuality is attained, and each individual human being, as mind, may be said to be the entire species. Inasmuch as he can form universals in his mind, he can realize the most abstract thought; and he is conscious. Consciousness begins when one can seize the pure universal in the presence of immediate objects here and now. The sense-perception of the mere animal, therefore, differs from that of the human being in this:—— The human being knows himself as subject that sees the object, while the animal sees the object, but does not separate himself, as universal, from the special act of seeing. To know that I am I, is to know the most general of objects, and to carry out abstraction to its very last degree; and yet this is what all human beings do, young or old, savage or civilized. The savage invents and uses language——an act of the species, but which the species cannot do without the participation of the individual. It should be carefully noted that this activity of generalization which produces language, and characterizes the human from the brute, is not the generalization of the activity of thought, so-called. It is the preparation for thought. These general types of things are the things which thought deals with. Thought does not deal with mere immediate objects of the senses; it deals rather with the objects which are indicated by words——_i.e._, general objects. Some writers would have us suppose that we do not arrive at general notions except by the process of classification and abstraction, in the mechanical manner that they lay down for this purpose. The fact is that the mind has arrived at these general ideas in the process of learning language. In infancy, most children have learned such words as _is_, _existence_, _being_, _nothing_, _motion_, _cause_, _change_, _I_, _you_, _he_, etc., etc. But the point is not the mere arrival at these ideas. Education does not concern itself with that; it does not concern itself with children who have not yet learned to talk——that is left for the nursery.
