I am fully persuaded that one of the best Springs of generous and
worthy Actions, is the having generous and worthy Thoughts of our
selves. Whoever has a mean Opinion of the Dignity of his Nature, will
act in no higher a Rank than he has allotted himself in his own
Estimation. If he considers his Being as circumscribed by the
uncertain Term of a few Years, his Designs will be contracted into the
same narrow Span he imagines is to bound his Existence. How can he
exalt his Thoughts to any thing great and noble, who only believes
that, after a short Turn on the Stage of this World, he is to sink
into Oblivion, and to lose his Consciousness for ever?

For this Reason I am of Opinion, that so useful and elevated a
Contemplation as that of the _Souls Immortality_ cannot be resumed
too often. There is not a more improving Exercise to the human Mind,
than to be frequently reviewing its own great Privileges and
Endowments; nor a more effectual Means to awaken in us an Ambition
raised above low Objects and little Pursuits, than to value our selves
as Heirs of Eternity.

It is a very great Satisfaction to consider the best and wisest of
Mankind in all Nations and Ages, asserting, as with one Voice, this
their Birthright, and to find it ratify'd by an express Revelation. At
the same time if we turn our Thoughts inward upon our selves, we may
meet with a kind of secret Sense concurring with the Proofs of our own
Immortality.

You have, in my Opinion, raised a good presumptive Argument from the
increasing Appetite the Mind has to Knowledge, and to the extending
its own Faculties, which cannot be accomplished, as the more
