This then is a sensible proof of the double relation of impressions and ideas.

From one instance so evident as this we may form a judgment of the rest.
This may also serve in another view to illustrate what I have insisted on concerning the origin of pride and humility, love and hatred.

I have observed, that though self be the object of the first set of passions, and some other person of the second, yet these objects cannot alone be the causes of the passions; as having each of them a relation to two contrary affections, which must from the very first moment destroy each other.

Here then is the situation of the mind, as I have already described it.

It has certain organs naturally fitted to produce a passion; that passion, when produced, naturally turns the view to a certain object.
