This contrivance of nature is easily conceived.
We have many instances of such a situation of affairs.

The nerves of the nose and palate are so disposed, as in certain circumstances to convey such peculiar sensations to the mind: The sensations of lust and hunger always produce in us the idea of those peculiar objects, which are suitable to each appetite.

These two circumstances are united in pride.
The organs are so disposed as to produce the passion; and the passion, after its production, naturally produces a certain idea.

All this needs no proof.

It is evident we never should be possest of that passion, were there not a disposition of mind proper for it; and it is as evident, that the passion always turns our view to ourselves, and makes us think of our own qualities and circumstances.
This being fully comprehended, it may now be asked, WHETHER NATURE PRODUCES THE PASSION IMMEDIATELY, OF HERSELF; OR WHETHER SHE MUST BE ASSISTED BY THE CO-OPERATION OF OTHER CAUSES?
For it is observable, that in this particular her conduct is different in the different passions and sensations.
