have

distinct

by us infinite, whereas Duration and Extension are apt to be so;

which arises from hence, That in Number we are at one end as it

were: for there being in Number nothing less than an Unite, we

there stop, and are at an end; but in addition, or increase of Num-

ber, we can set no Bounds: and so it is like a Line, whereof one end

terminating with us, the other is extended still forwards beyond all

that we can conceive; but in Space and Duration it is otherwise.

For in Duration, we consider it, as if this Line of Number were

extended both ways to an unconceivable, undeterminate, and

infinite length; which is evident to any one, that will but reflect on

what Consideration he hath of Eternity; which, I suppose, he will

find to be nothing else, but the turning this Infinity of Number

both ways,

would consider Eternity,

from our selves, and the present time we are in, repeat in our

Minds the

Duration past, with a prospect of proceeding, in such Addition,

with all the Infinity of Number; and when we would consider

— 216 —

Eternity, selves, and reckon by multiplied Periods yet to come, still extend-

ing that Line of Number, as before; and these two being put

together, are that infinite Duration we call

turn our view either way forwards or backwards, appears infinite,

because we still turn that way the infinite end of Number,

Power still of adding more.
