So that though a likeness may occasionally produce that passion by suggesting a more advantageous idea of ourselves, it is there the view fixes at last, and the passion finds its ultimate and final cause.
There are instances, indeed, wherein men shew a vanity in resembling a great man in his countenance, shape, air, or other minute circumstances, that contribute not in any degree to his reputation; but it must be confessed that this extends not very far, nor is of any considerable moment in these affections.

For this I assign the following reason.

We can never have a vanity of resembling in trifles any person, unless he be possessed of very shining qualities, which give us a respect and veneration for him.

These qualities, then, are, properly speaking, the causes of our vanity, by means of their relation to ourselves.

Now after what manner are they related to ourselves?
They are parts of the person we value, and consequently connected with these trifles; which are also supposed to be parts of him.
