CHAPTER III.
CONCEPTION.
Character of this Power.—This term has been employed in various senses by different writers. It does not denote properly a distinct faculty of the mind. I conceive of a thing when I make it a distinct object of thought, when I apprehend it, when I construe it to myself as a possible thing, and as being thus and thus. This form of mental activity enters more or less into all our mental operations; it is involved in perception, memory, imagination, abstraction, judgment, reasoning, etc. For this reason it is not to be ranked as one of, and correlate with, these several specific faculties. Like the power of thought, and hardly even more limited than that, it underlies all the special faculties, and is essential to them all. Such at least is the ordinary acceptation of the term; and when we employ it to denote some specific form of mental activity, we employ it in a sense aside from its usual and established meaning.
Objects of Conception.—I conceive of an absent object of sight, as, e. g., the appearance of an absent friend, or of a foreign city, of the march of an army, or the eruption of a volcano. I conceive also of a mathematical truth, or a problem in astronomy. My conceptions are not limited to former perceptions or sensations, nor even to objects of sensible perception. They are not limited to material and sensible objects. They embrace the past and the future, the actual and the ideal, the sensible and the super-sensible.
Conceptions neither true nor false.—Our conceptions are neither true nor false, in themselves considered; they become so only when attended with some exercise of judgment or of belief. We conceive of a mountain of gold or of glass, and this simple conception has nothing to do with truth or error. When we conceive of it, however, as actually existing, and in this or that place, or when we simply judge that such a mountain is somewhere to be found, then such judgment or belief is either true or false; but it is no longer simple conception.
Not always Possibilities; nor possible Things always conceivable.—Our conceptions are not always possibilities. We can conceive of some things not within the limits of possibility. On the other hand, not every thing possible even is conceivable. Existence without beginning or end is possible, but it is not in the power of the human mind, strictly speaking, to conceive of such a thing. I know that Deity thus exists. I understand what is meant by such a proposition, and I believe it. But I cannot construe it to myself as a definite intellection, an apprehension, as I can conceive of the existence of a city or a continent, or of the truth of a mathematical proposition.
The same may be said of the ideas of the infinite and the absolute. They are not properly within the limits of thought, of apprehension, to the human mind. Thought in its very nature imposes a limitation on the object which is thought of—fathoms it—passes around it with its measuring line—apprehends it: only so far as this is done is the thing actually thought; only so far as it can be done is the thing really thinkable. But the infinite, the unconditioned, the absolute, in their very nature unlimited, cannot be shut up thus within the narrow lines of human thought. They are inconceivable. They are not, however, contradictory to thought. They may be true; they are true and real, though we cannot properly conceive them.
The Inconceivable becomes Impossible, when.—Not every thing then which is inconceivable is impossible, nor, on the other hand, is every thing which is impossible inconceivable. The inconceivable is impossible, at least it can be known to be so, only when it is either self-contradictory—as that a thing should be and not be at the same time—that a part is equal to the whole, etc.; or when it is contradictory of the laws of thought, as that two straight lines should enclose a space—that an event may occur without a cause—that space is not necessary to the existence of matter, or time to the succession of events. These things are unthinkable but they are more than that, contradictory of the established laws of thought; and they are impossible, because thus contradictory, and not merely because inconceivable. It is hardly true, as is sometimes affirmed, and as Dr. Wayland has stated, that our conceptions are the limits of possibility.
Mr. Stewart's use of the term Conception.—Mr. Stewart has employed the term Conception in a somewhat peculiar manner, and has assigned it a definite place among the faculties of the mind. He uses it to denote "that power of the mind which enables it to form a notion of an absent object of perception, or of a sensation which we have formerly felt." It is the office of this faculty "to present us with an exact transcript of what we have felt or perceived." In this respect it differs from imagination, which gives not an exact transcript, but one more or less altered or modified, combining our conceptions so as to form new results. It differs from memory in that it involves no idea of time, no recognition of the thing conceived, as a thing formerly perceived.
