      §10. The Reason I have for this odd conjecture is, from observ-
ing that in the Impressions made upon any of our Senses, we can but
to a certain degree perceive any Succession; which if exceeding
quick, the Sense of Succession is lost, even in Cases where it is
— 185 —
evident, that there is a real Succession. Let a Cannon-Bullet pass
through a Room, and in its way take with it any Limb, or fleshy
Parts of a Man; ’tis as clear as any Demonstration can be, that it
must strike successively the two sides of the Room: ’Tis also evi-
dent, that it must touch one part of the Flesh first, and another
after; and so in Succession: And yet I believe, no Body, who ever
felt the pain of such a shot, or heard the blow against the two
distant Walls, could perceive any Succession, either in the pain, or
sound of so swift a stroke. Such a part of Duration as this, wherein
we perceive no Succession, is that which we may call an Instant; and
is that which takes up the time of only one Idea in our Minds, without the
Succession of another, wherein therefore we perceive no Succession
at all.
