So in the analogous case of objects. The proper names Peter, Paul, John, &c., stand in my mind as marks of my individual concepts: the term Man serves to sum up all the points of agreement between them—and also between all other individuals of their kind—without regard to their points of disagreement: the word Animal takes a still wider range, and so with nearly all words denoting objects. Like words connoting qualities, they may be arranged in rank above rank according to the range of their generality: and it is obvious that the wider this range the further is their meaning withdrawn from anything that can ever have been an object of immediate perception. We shall afterwards find it is of the highest importance to note that these remarks apply quite as much to actions and states as they do to objects and qualities. Verbs, like nouns and adjectives, may be merely the names of simple recepts, or they may be compounds of other concepts—in either case differing from nouns and adjectives only in that they have to do with actions and states. To sow, to dig, to spin, &c., are names of particular actions; to labour is the name of a more general action; to live is the symbol of a concept yet more general. And it is obvious that here, as previously, the more general concepts are built out of the more special. Later on I will adduce evidence to show that, whether we look to the growing infant or to the history of mankind as newly unearthed by the researches of the philologist, we alike find that no one of these divisions of simple concepts—namely, nouns, adjectives, and verbs—appears to present priority over the others. Or, if there is any evidence of such priority, it appears to incline in favour of nouns and verbs. But the point on which I desire to fasten attention at present is the enormous leverage which is furnished to the faculty of ideation by thus using words as the mental equivalents of ideas. For by the help of these symbols we climb into higher and higher regions of abstraction: by thinking in verbal signs we think, as it were, with the semblance of ideas: we dispense altogether with the necessity of actual images, whether of precepts or of recepts: we quit the sphere of sense, and rise to that of thought.
