We are likewise to take Notice that every particular Faculty is capable of being employed on a very great Variety of Objects.  The Understanding, for Example, may be happy in the Contemplation of Moral, Natural, Mathematical, and other Kinds of Truth.  The Memory likewise may turn itself to an infinite Multitude of Objects, especially when the Soul shall have pass’d through the Space of many Millions of Years, and shall reflect with Pleasure on the Days of Eternity.  Every other Faculty may be consider’d in the same Extent.

We cannot question but that the Happiness of a Soul will be adequate to its Nature, and that it is not endowed with any Faculties which are to lie useless and unemploy’d.  The Happiness is to be the Happiness of the whole Man, and we may easily conceive to our selves the Happiness of the Soul, whilst any one of its Faculties is in the Fruition of its chief Good.  The Happiness may be of a more exalted Nature in Proportion as the Faculty employed is so, but as the whole Soul acts in the Exertion of any of its particular Powers, the whole Soul is happy in the Pleasure which arises from any of its particular Acts.  For notwithstanding, as has been before hinted, and as it has been taken Notice of by one of the greatest modern Philosophers, [2] we divide the Soul into several Powers and Faculties, there is no such Division in the Soul it self, since it is the whole Soul that remembers, understands, wills, or imagines.  Our manner of considering the Memory, Understanding, Will, Imagination, and the like Faculties, is for the better enabling us to express our selves in such abstracted Subjects of Speculation, not that there is any such Division in the Soul it self.

Seeing then that the Soul has many different Faculties, or in other Words, many different Ways of acting; that it can be intensely pleas’d, or made happy by all these different Faculties, or Ways of acting; that it may be endow’d with several latent Faculties, which it is not at present in a Condition to exert; that we cannot believe the Soul is endow’d with any Faculty which is of no Use to it; that whenever any one of these Faculties is transcendently pleased, the Soul is in a State of Happiness; and in the last Place considering that the Happiness of another World is to be the Happiness of the whole Man; who can question but that there is an infinite Variety in those Pleasures we are speaking of; and that this Fulness of Joy will be made up of all those Pleasures which the Nature of the Soul is capable of receiving.

We shall be the more confirmed in this Doctrine, if we observe the Nature of Variety, with regard to the Mind of Man.  The Soul does not care to be always in the same bent.  The Faculties relieve one another by Turns, and receive an additional Pleasure from the Novelty of those Objects about which they are conversant.
