Such again are the ideal personages who figure in romances and dramas of the old school; tyrants, monks, crusaders, princes in disguise, and captive damsels; or benevolent or angry fathers, and spendthrift heirs; like the symbolical characters in some of Shakespeare’s plays, “a Tapster,” or “a Lord Mayor,” or in the stage directions “Enter two murderers.” What I have been illustrating in the case of persons, might be instanced in regard to places, transactions, physical calamities, events in history. Words which are used by an eye-witness to express things, unless he be especially eloquent or graphic, may only convey general notions. Such is, and ever must be, the popular and ordinary mode of apprehending language. On few subjects only have any of us the opportunity of realizing in our minds what we speak and hear about; and we fancy that we are doing justice to individual men and things by making them a mere _synthesis_ of qualities, as if any number whatever of abstractions would, by being fused together, be equivalent to one concrete. ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ Here then we have two modes of thought, both using the same words, both having one origin, yet with nothing in common in their results. The informations of sense and sensation are the initial basis of both of them; but in the one we take hold of objects from within them, and in the other we view them from without them; we perpetuate them as images in the one case, we transform them into notions in the other. And natural to us as are both processes in their first elements and in their growth, however divergent and independent in their direction, they cannot really be inconsistent with each other; yet no one from the sight of a horse or a dog would be able to anticipate its zoological definition, nor from a knowledge of its definition to draw such a picture as would direct another to the living specimen. Each use of propositions has its own excellence and serviceableness, and each has its own imperfection. To apprehend notionally is to have breadth of mind, but to be shallow; to apprehend really is to be deep, but to be narrow-minded. The latter is the conservative principle of knowledge, and the former the principle of its advancement. Without the apprehension of notions, we should for ever pace round one small circle of knowledge; without a firm hold upon things, we shall waste ourselves in vague speculations. However, real apprehension has the precedence, as being the scope and end and the test of notional; and the fuller is the mind’s hold upon things or what it considers such, the more fertile is it in its aspects of them, and the more practical in its definitions.
