Sect. IIThere is only one difficulty in this experiment, which it will be necessary to account for, before we proceed any farther. It is evident, that though all passions pass easily from one object to another related to it, yet this transition is made with greater facility, where the more considerable object is first presented, and the lesser follows it, than where this order is reversed, and the lesser takes the precedence. Thus it is more natural for us to love the son upon account of the father, than the father upon account of the son; the servant for the master, than the master for the servant; the subject for the prince, than the prince for the subject. In like manner we more readily contract a hatred against a whole family, where our first quarrel is with the head of it, than where we are displeased with a son, or servant, or some inferior member. In short, our passions, like other objects, descend with greater facility than they ascend.

That we may comprehend, wherein consists the difficulty of explaining this phænomenon, we must consider, that the very same reason, which determines the imagination to pass from remote to contiguous objects, with more facility than from contiguous to remote, causes it likewise to change with more ease, the less for the greater, than the greater for the less. Whatever has the greatest influence is most taken notice of; and whatever is most taken notice of, presents itself most readily to the imagination. We are more apt to over-look in any subject, what is trivial, than what appears of considerable moment; but especially if the latter takes the precedence, and first engages our attention. Thus if any accident makes us consider the Satellites of JUPITER, our fancy is naturally determined to form the idea of that planet; but if we first reflect on the principal planet, it is more natural for us to overlook its attendants. The mention of the provinces of any empire conveys our thought to the seat of the empire; but the fancy returns not with the same facility to the consideration of the provinces. The idea of the servant makes us think of the master; that of the subject carries our view to the prince. But the same relation has not an equal influence in conveying us back again. And on this is founded that reproach of Cornelia to her sons, that they ought to be ashamed she should be more known by the title of the daughter of Scipio than by that of the mother of the Gracchi. This was, in other words, exhorting them to render themselves as illustrious and famous as their grandfather, otherwise the imagination of the people, passing from her who was intermediate, and placed in an equal relation to both, would always leave them, and denominate her by what was more considerable and of greater moment. On the same principle is founded that common custom of making wives bear the name of their husbands, rather than husbands that of their wives; as also the ceremony of giving the precedency to those, whom we honour and respect. We might find many other instances to confirm this principle, were it not already sufficiently evident.

Now since the fancy finds the same facility in passing from the lesser to the greater, as from remote to contiguous, why does not this easy transition of ideas assist the transition of passions in the former case, as well as in the latter? The virtues of a friend or brother produce first love, and then pride; because in that case the imagination passes from remote to contiguous, according to its propensity. Our own virtues produce not first pride, and then love to a friend or brother; because the passage in that case would be from contiguous to remote, contrary to its propensity. But the love or hatred of an inferior causes not readily any passion to the superior, though that be the natural propensity of the imagination: While the love or hatred of a superior, causes a passion to the inferior, contrary to its propensity. In short, the same facility of transition operates not in the same manner upon superior and inferior as upon contiguous and remote. These two phaenomena appear contradictory, and require some attention to be reconciled.

As the transition of ideas is here made contrary to the natural propensity of the imagination, that faculty must be overpowered by some stronger principle of another kind; and as there is nothing ever present to the mind but impressions and ideas, this principle must necessarily lie in the impressions. Now it has been observed, that impressions or passions are connected only by their resemblance, and that where any two passions place the mind in the same or in similar dispositions, it very naturally passes from the one to the other: As on the contrary, a repugnance in the dispositions produces a difficulty in the transition of the passions. But it is observable, that this repugnance may arise from a difference of degree as well as of kind; nor do we experience a greater difficulty in passing suddenly from a small degree of love to a small degree of hatred, than from a small to a great degree of either of these affections. A man, when calm or only moderately agitated, is so different, in every respect, from himself, when disturbed with a violent passion, that no two persons can be more unlike; nor is it easy to pass from the one extreme to the other, without a considerable interval betwixt them.

The difficulty is not less, if it be not rather greater, in passing from the strong passion to the weak, than in passing from the weak to the strong, provided the one passion upon its appearance destroys the other, and they do not both of them exist at once. But the case is entirely altered, when the passions unite together, and actuate the mind at the same time. A weak passion, when added to a strong, makes not so considerable a change in the disposition, as a strong when added to a weak; for which reason there is a closer connexion betwixt the great degree and the small, than betwixt the small degree and the great.

The degree of any passion depends upon the nature of its object; and an affection directed to a person, who is considerable in our eyes, fills and possesses the mind much more than one, which has for its object a person we esteem of less consequence. Here then the contradiction betwixt the propensities of the imagination and passion displays itself. When we turn our thought to a great and a small object, the imagination finds more facility in passing from the small to the great, than from the great to the small; but the affections find a greater difficulty: And as the affections are a more powerful principle than the imagination, no wonder they prevail over it, and draw the mind to their side. In spite of the difficulty of passing from the idea of great to that of little, a passion directed to the former, produces always a similar passion towards the latter; when the great and little are related together. The idea of the servant conveys our thought most readily to the master; but the hatred or love of the master produces with greater facility anger or good-will to the servant. The strongest passion in this case takes the precedence; and the addition of the weaker making no considerable change on the disposition, the passage is by that means rendered more easy and natural betwixt them.

As in the foregoing experiment we found, that a relation of ideas, which, by any particular circumstance, ceases to produce its usual effect of facilitating the transition of ideas, ceases likewise to operate on the passions; so in the present experiment we find the same property of the impressions. Two different degrees of the same passion are surely related together; but if the smaller be first present, it has little or no tendency to introduce the greater; and that because the addition of the great to the little, produces a more sensible alteration on the temper, than the addition of the little to the great. These phaenomena, when duly weighed, will be found convincing proofs of this hypothesis.

And these proofs will be confirmed, if we consider the manner in which the mind here reconciles the contradiction, I have observed betwixt the passions and the imagination. The fancy passes with more facility from the less to the greater, than from the greater to the less: But on the contrary a violent passion produces more easily a feeble, than that does a violent. In this opposition the passion in the end prevails over the imagination; but it is commonly by complying with it, and by seeking another quality, which may counter-ballance that principle, from whence the opposition arises. When we love the father or master of a family, we little think of his children or servants. But when these are present with us, or when it lies any ways in our power to serve them, the nearness and contiguity in this case encreases their magnitude, or at least removes that opposition, which the fancy makes to the transition of the affections. If the imagination finds a difficulty in passing from greater to less, it finds an equal facility in passing from remote to contiguous, which brings the matter to an equality, and leaves the way open from the one passion to the other.
