In sympathy there is an evident conversion of an idea into an impression. This conversion arises from the relation of objects to ourself. Ourself is always intimately present to us. Let us compare all these circumstances, and we shall find, that sympathy is exactly correspondent to the operations of our understanding; and even contains something more surprizing and extraordinary. It is now time to turn our view from the general consideration of sympathy, to its influence on pride and humility, when these passions arise from praise and blame, from reputation and infamy. We may observe, that no person is ever praised by another for any quality, which would not, if real, produce, of itself, a pride in the person possest of it. The elogiums either turn upon his power, or riches, or family, or virtue; all of which are subjects of vanity, that we have already explained and accounted for. It is certain, then, that if a person considered himself in the same light, in which he appears to his admirer, he would first receive a separate pleasure, and afterwards a pride or self-satisfaction, according to the hypothesis above explained. Now nothing is more natural than for us to embrace the opinions of others in this particular; both from sympathy, which renders all their sentiments intimately present to us; and from reasoning, which makes us regard their judgment, as a kind of argument for what they affirm. These two principles of authority and sympathy influence almost all our opinions; but must have a peculiar influence, when we judge of our own worth and character. Such judgments are always attended with passion;[7] and nothing tends more to disturb our understanding, and precipitate us into any opinions, however unreasonable, than their connexion with passion; which diffuses itself over the imagination, and gives an additional force to every related idea. To which we may add, that being conscious of great partiality in our own favour, we are peculiarly pleased with any thing, that confirms the good opinion we have of ourselves, and are easily shocked with whatever opposes it.

All this appears very probable in theory; but in order to bestow a full certainty on this reasoning, we must examine the phaenonena of the passions, and see if they agree with it.
