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 tho' the one impression be easily transfus'd into the other, yet the change of objects is suppos'd 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 wou'd conclude from analogy, after balancing these arguments, wou'd 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 it 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, tho' the most advantageous one, can never give rise to any constant and establish'd passion.
Most fortunately all this reasoning is found to be exactly conformable to experience, and the phenomena of the passions. Suppose I were travelling with a companion thro' a country, to which we are both utter strangers; 'tis 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 consider'd as the overflowings of an elevate or humane disposition, than as an establish'd passion. The case is the same where the object produces uneasiness.
