The perception of the connexion or repugnancy, agreement or disagreement, that there is between any of our ideas.

Faculties not real beings.
These powers of the mind, viz.

of perceiving, and of preferring, are usually called by another name.

And the ordinary way of speaking is, that the understanding and will are two FACULTIES of the mind; a word proper enough, if it be used, as all words should be, so as not to breed any confusion in men's thoughts, by being supposed (as I suspect it has been) to stand for some real beings in the soul that performed those actions of understanding and volition.
