the skill of the imitator, however excellent. Aristotle has spoken so much and so solidly upon the force of imitation in his Poetics, that it makes any further discourse upon this subject the less necessary. SECTION XVII. AMBITION. Although imitation is one of the great instruments used by Providence in bringing our nature towards its perfection, yet if men gave themselves up to imitation entirely, and each followed the other, and so on in an eternal circle, it is easy to see that there never could be any improvement amongst them. Men must remain as brutes do, the same at the end that they are at this day, and that they were in the beginning of the world. To prevent this, God has planted in man a sense of ambition, and a satisfaction arising from the contemplation of his excelling his fellows in something deemed valuable amongst them. It is this passion that drives men to all the ways we see in use of signalizing themselves, and that tends to make whatever excites in a man the idea of this distinction so very pleasant. It has been so strong as to make very miserable men take comfort, that they were supreme in misery; and certain it is that, where we cannot distinguish ourselves by something excellent, we begin to take a complacency in some singular infirmities, follies, or defects of one kind or other. It is on this principle that flattery is so prevalent; for flattery is no more than what raises in a man's mind an idea of a preference which he has not. Now, whatever, either on good or upon bad grounds, tends to raise a man in his own opinion, produces a sort of swelling and triumph, that is extremely grateful to the human mind; and this swelling is never more perceived, nor operates with more force, than when without danger we are conversant with terrible objects; the mind always claiming to itself some part of the dignity and importance of the things which it contemplates. Hence proceeds what Longinus has observed of that glorying and sense of inward greatness, that always fills the reader of such passages in poets and orators as are sublime: it is what every man must have felt in himself upon such occasions. SECTION XVIII. THE RECAPITULATION. To draw the whole of what has been said into a few distinct points:--The passions which belong to self-preservation turn on pain and danger; they are simply painful when their causes immediately affect us; they are delightful when we have an idea of pain and danger, without being actually in such circumstances; this delight I have not called pleasure, because it turns on pain, and because it is different enough from any idea of positive pleasure. Whatever excites this delight, I call _sublime_. The passions belonging to self-preservation are the strongest of all the passions.
