For, as regards a vacuum or void, which we may cogitate as out and beyond the field of possible experience (the world), such a question cannot come before the tribunal of mere understanding, which decides only upon questions that concern the employment of given phenomena for the construction of empirical cognition. In such a case, we merely fail to find the additional form of unity we expected, but we do not lose the rational unity which the mind requires in its procedure in experience. Afterwards experience comes in play to persuade us that two bodies, situated in the manner above-described, have really such a capacity of receiving body betwixt them, and that there is no obstacle to the conversion of the invisible and intangible distance into one that is visible and tangible. Hence the principles of the mathematical use of the categories will possess a character of absolute necessity, that is, will be apodeictic; those, on the other hand, of the dynamical use, the character of an a priori necessity indeed, but only under the condition of empirical thought in an experience, therefore only mediately and indirectly. For it is not the idea itself, but only the employment of the idea in relation to possible experience, that is transcendent or immanent. For first, daily experience convinces us, that pride requires certain causes to excite it, and languishes when unsupported by some excellency in the character, in bodily accomplishments, in cloaths, equipage or fortune. Now besides what I have already proved, that even in human nature no relation can ever alone produce any action: besides this, I say, it has been shewn, in treating of the understanding, that there is no connexion of cause and effect, such as this is supposed to be, which is discoverable otherwise than by experience, and of which we can pretend to have any security by the simple consideration of the objects. The science of mathematics presents the most brilliant example of the extension of the sphere of pure reason without the aid of experience. But it is utterly impossible to go beyond our conception, without the aid of experience--which presents to the mind nothing but phenomena, or to attain by the help of mere conceptions to a conviction of the existence of new kinds of objects or supernatural beings.
