There are few persons, that are satisfyed with their own character, or genius, or fortune, who are nor desirous of shewing themselves to the world, and of acquiring the love and approbation of mankind. Now it is evident, that the very same qualities and circumstances, which are the causes of pride or self-esteem, are also the causes of vanity or the desire of reputation; and that we always put to view those particulars with which in ourselves we are best satisfyed. But if love and esteem were not produced by the same qualities as pride, according as these qualities are related to ourselves or others, this method of proceeding would be very absurd, nor could men expect a correspondence in the sentiments of every other person, with those themselves have entertained. It is true, few can form exact systems of the passions, or make reflections on their general nature and resemblances. But without such a progress in philosophy, we are not subject to many mistakes in this particular, but are sufficiently guided by common experience, as well as by a kind of presentation; which tells us what will operate on others, by what we feel immediately in ourselves.

Since then the same qualities that produce pride or humility, cause love or hatred; all the arguments that have been employed to prove, that the causes of the former passions excite a pain or pleasure independent of the passion, will be applicable with equal evidence to the causes of the latter.

Upon duly weighing these arguments, no one will make any scruple to assent to that conclusion I draw from them, concerning the transition along related impressions and ideas, especially as it is a principle, in itself, so easy and natural. But that we may place this system beyond doubt both with regard to love and hatred, pride and humility, it will be proper to make some new experiments upon all these passions, as well as to recall a few of these observations, which I have formerly touched upon.

In order to make these experiments, let us suppose I am in company with a person, whom I formerly regarded without any sentiments either of friendship or enmity. Here I have the natural and ultimate object of all these four passions placed before me. Myself am the proper object of pride or humility; the other person of love or hatred.

Regard now with attention the nature of these passions, and their situation with respect to each other. It is evident here are four affections, placed, as it were, in a square or regular connexion with, and distance from each other. The passions of pride and humility, as well as those of love and hatred, are connected together by the identity of their object, which to the first set of passions is self, to the second some other person. These two lines of communication or connexion form two opposite sides of the square. Again, pride and love are agreeable passions; hatred and humility uneasy.

This similitude of sensation betwixt pride and love, and that betwixt humility and hatred form a new connexion, and may be considered as the other two sides of the square. Upon the whole, pride is connected with humility, love with hatred, by their objects or ideas: Pride with love, humility with hatred, by their sensations or impressions.

I say then, that nothing can produce any of these passions without bearing it a double relation, viz, of ideas to the object of the passion, and of sensation to the passion itself. This we must prove by our experiments. First Experiment. To proceed with the greater order in these experiments, let us first suppose, that being placed in the situation above-mentioned, viz, in company with some other person, there is an object presented, that has no relation either of impressions or ideas to any of these passions. Thus suppose we regard together an ordinary stone, or other common object, belonging to neither of us, and causing of itself no emotion, or independent pain and pleasure: It is evident such an object will produce none of these four passions.

Let us try it upon each of them successively. Let us apply it to love, to hatred, to humility, to pride; none of them ever arises in the smallest degree imaginable. Let us change the object, as oft as we please; provided still we choose one, that has neither of these two relations. Let us repeat the experiment in all the dispositions, of which the mind is susceptible. No object, in the vast variety of nature, will, in any disposition, produce any passion without these relations.

Second Experiment. Since an object, that wants both these relations can never produce any passion, let us bestow on it only one of these relations; and see what will follow. Thus suppose, I regard a stone or any common object, that belongs either to me or my companion, and by that means acquires a relation of ideas to the object of the passions: It is plain, that to consider the matter a priori, no emotion of any kind can reasonably be expected. For besides, that a relation of ideas operates secretly and calmly on the mind, it bestows an equal impulse towards the opposite passions of pride and humility, love and hatred, according as the object belongs to ourselves or others; which opposition of the passions must destroy both, and leave the mind perfectly free from any affection or emotion. This reasoning a priori is confirmed by experience.

No trivial or vulgar object, that causes not a pain or pleasure, independent of the passion, will ever, by its property or other relations either to ourselves or others, be able to produce the affections of pride or humility, love or hatred.

Third Experiment. It is evident, therefore, that a relation of ideas is not able alone to give rise to these affections. Let us now remove this relation, and in its stead place a relation of impressions, by presenting an object, which is agreeable or disagreeable, but has no relation either to ourself or companion; and let us observe the consequences. To consider the matter first a priori, as in the preceding experiment; we may conclude, that the object will have a small, but an uncertain connexion with these passions. For besides, that this relation is not a cold and imperceptible one, it has not the inconvenience of the relation of ideas, nor directs us with equal force to two contrary passions, which by their opposition destroy each other.

But if we consider, on the other hand, that this transition from the sensation to the affection is not forwarded by any principle, that produces a transition of ideas; but, on the contrary, that though the one impression be easily transfused into the other, yet the change of objects is supposed contrary to all the principles, that cause a transition of that kind; we may from thence infer, that nothing will ever be a steady or durable cause of any passion, that is connected with the passion merely by a relation of impressions. What our reason would conclude from analogy, after balancing these arguments, would be, that an object, which produces pleasure or uneasiness, but has no manner of connexion either with ourselves or others, may give such a turn to the disposition, as that may naturally fall into pride or love, humility or hatred, and search for other objects, upon which by a double relation, it can found these affections; but that an object, which has only one of these relations, though the most advantageous one, can never give rise to any constant and established passion.

Most fortunately all this reasoning is found to be exactly conformable to experience, and the phaenomena of the passions. Suppose I were travelling with a companion through a country, to which we are both utter strangers; it is evident, that if the prospects be beautiful, the roads agreeable, and the inns commodious, this may put me into good humour both with myself and fellow-traveller. But as we suppose, that this country has no relation either to myself or friend it can never be the immediate cause of pride or love; and therefore if I found not the passion on some other object, that bears either of us a closer relation, my emotions are rather to be considerd as the overflowings of an elevate or humane disposition, than as an established passion. The case is the same where the object produces uneasiness.

Fourth Experiment. Having found, that neither an object without any relation of ideas or impressions, nor an object, that has only one relation, can ever cause pride or humility, love or hatred; reason alone may convince us, without any farther experiment, that whatever has a double relation must necessarily excite these passions; since it is evident they must have some cause. But to leave as little room for doubt as possible, let us renew our experiments, and see whether the event in this case answers our expectation. I choose an object, such as virtue, that causes a separate satisfaction: On this object I bestow a relation to self; and find, that from this disposition of affairs, there immediately arises a passion. But what passion?

That very one of pride, to which this object bears a double relation. Its idea is related to that of self, the object of the passion: The sensation it causes resembles the sensation of the passion. That I may be sure I am not mistaken in this experiment, I remove first one relation; then another; and find, that each removal destroys the passion, and leaves the object perfectly indifferent. But I am not content with this. I make a still farther trial; and instead of removing the relation, I only change it for one of a different kind.

I suppose the virtue to belong to my companion, not to myself; and observe what follows from this alteration. I immediately perceive the affections wheel to about, and leaving pride, where there is only one relation, viz, of impressions, fall to the side of love, where they are attracted by a double relation of impressions and ideas. By repeating the same experiment, in changing anew the relation of ideas, I bring the affections back to pride; and by a new repetition I again place them at love or kindness. Being fully convinced of the influence of this relation, I try the effects of the other; and by changing virtue for vice, convert the pleasant impression, which arises from the former, into the disagreeable one, which proceeds from the latter. The effect still answers expectation.

Vice, when placed on another, excites, by means of its double relations, the passion of hatred, instead of love, which for the same reason arises from virtue. To continue the experiment, I change anew the relation of ideas, and suppose the vice to belong to myself. What follows? What is usual. A subsequent change of the passion from hatred to humility.

This humility I convert into pride by a new change of the impression; and find after all that I have compleated the round, and have by these changes brought back the passion to that very situation, in which I first found it.

But to make the matter still more certain, I alter the object; and instead of vice and virtue, make the trial upon beauty and deformity, riches and poverty, power and servitude. Each of these objects runs the circle of the passions in the same manner, by a change of their relations: And in whatever order we proceed, whether through pride, love, hatred, humility, or through humility, hatred, love, pride, the experiment is not in the least diversifyed. Esteem and contempt, indeed, arise on some occasions instead of love and hatred; but these are at the bottom the same passions, only diversifyed by some causes, which we shall explain afterwards.
