extending
its own Faculties, which cannot be accomplished, as the more
restrained Perfection of lower Creatures may, in the Limits of a short
Life. I think another probable Conjecture may be raised from our
Appetite to Duration it self, and from a Reflection on our Progress
through the several Stages of it: _We are complaining_, as you observe
in a former Speculation, _of the Shortness of Life, and yet are
perpetually hurrying over the Parts of it, to arrive at certain little
Settlements, or imaginary Points of Rest, which are dispersed up and
down in it_.

Now let us consider what happens to us when we arrive at these
_imaginary Points of Rest_: Do we stop our Motion, and sit down
satisfied in the Settlement we have gain'd? or are we not removing the
Boundary, and marking out new Points of Rest, to which we press
forward with the like Eagerness, and which cease to be such as fast as
we attain them? Our Case is like that of a Traveller upon the _Alps_,
who should fancy that the Top of the next Hill must end his Journey,
because it terminates his Prospect; but he no sooner arrives as it,
than he sees new Ground and other Hills beyond it, and continues to
travel on as before. [1]

This is so plainly every Man's Condition in Life, that there is no
one who has observed any thing, but may observe, that as fast as his
Time wears away, his Appetite to something future remains. The Use
therefore I would make of it is this, That since Nature (as some love
to express it) does nothing in vain, or, to speak properly, since the
Author of our Being has planted no wandering Passion in it, no Desire
which has not its Object, Futurity is the proper Object of the Passion
so constantly exercis'd about it; and this Restlessness in the
present, this assigning our selves over to further Stages of Duration,
this successive grasping at somewhat still to come, appears to me
(whatever it may to others) as a kind of Instinct or natural Symptom
which the Mind of Man has of its own Immortality.

I take it at the same time for granted, that the Immortality of the
Soul is sufficiently established by other Arguments: And if so, this
Appetite, which otherwise would be very unaccountable and absurd,
seems very reasonable, and adds Strength to the Conclusion. But I am
amazed when I consider there are Creatures capable of Thought, who, in
spite of every Argument, can form to the
