SECT. V.—HOW THE SUBLIME IS PRODUCED
HAVING considered terror as producing an unnatural tension and certain violent emotions of the nerves; it easily follows, from what we have just said, that whatever is fitted to produce such a tension must be productive of a passion similar to terror,〖Part II. sect. 2.〗 and consequently must be a source of the sublime, though it should have no idea of danger connected with it. So that little remains towards showing the cause of the sublime, but to show that the instances we have given of it in the second part relate to such things as are fitted by nature to produce this sort of tension, either by the primary operation of the mind or the body. With regard to such things as effect by the associated idea of danger, there can be no doubt but that they produce terror, and act by some modification of that passion; and that terror, when sufficiently violent, raises the emotions of the body just mentioned, can as little be doubted. But if the sublime is built on terror, or some passion like it, which has pain for its object, it is previously proper to inquire how any species of delight can be derived from a cause so apparently contrary to it. I say delight, because, as I have often remarked, it is very evidently different in its cause, and in its own nature, from actual and positive pleasure.
