excite them. For as these passions are directly contrary, and have the same object in common; were their object also their cause; it cou'd never produce any degree of the one passion, but at the same time it must excite an equal degree of the other; which opposition and contrariety must destroy both. 'Tis impossible a man can at the same time be both proud and humble; and where he has different reasons for these passions, as frequently happens, the passions either take place alternately; or if they encounter, the one annihilates the other, as far as its strength goes, and the remainder only of that, which is superior, continues to operate upon the mind. But in the present case neither of the passions cou'd ever become superior; because supposing it to be the view only of ourself, which excited them, that being perfectly indifferent to either, must produce both in the very same proportion; or in other words, can produce neither. To excite any passion, and at the same time raise an equal share of its antagonist, is immediately to undo what was done, and must leave the mind at last perfectly calm and indifferent.
We must, therefore, make a distinction betwixt the cause and the object of these passions; betwixt that idea, which excites them, and that to which they direct their view, when excited. Pride and humility, being once rais'd, immediately turn our attention to ourself, and regard that as their ultimate and final object; but there is something farther requisite in order to raise them: Something, which is peculiar to one of the passions, and produces not both in the very same degree. The first idea, that is presented to the mind, is that of the cause or productive principle. This excites the passion, connected with it; and that passion, when excited, turns our view to another idea, which is that of self Here then is a passion plac'd betwixt two ideas, of which the one produces it, and the other is produc'd by it. The first idea, therefore, represents the cause, the second the object of the passion.
To begin with the causes of pride and humility; we may
