—Assiduo labuntur tempora motu
Non secus ac flumen. Neque enim consistere flumen,
Nec levis hora potest: sed ut unda, impellitur unda,

Tempora sic fugiunt pariter, pariterque sequuntur;
Et nova sunt semper. Nam quod fuit ante, relictum est;
Fitque quod haud fuerat: momentaque cuncta novantur.

We consider infinite Space as an Expansion without a Circumference: We consider Eternity, or infinite Duration, as a Line that has neither a Beginning nor an End. In our Speculations of infinite Space, we consider that particular Place in which we exist, as a kind of Center to the whole Expansion. In our Speculations of Eternity, we consider the Time which is present to us as the Middle, which divides the whole Line into two equal Parts. For this Reason, many witty Authors compare the present Time to an Isthmus or narrow Neck of Land, that rises in the midst of an Ocean, immeasurably diffused on either Side of it.

Philosophy, and indeed common Sense, naturally throws Eternity under two Divisions; which we may call in
