Full Idea
We take it that it is impossible for the nows to be adjoining one another, as it is for a point to be adjoining a point.
Gist of Idea
Nows can't be linked together, any more than points on a line
Source
Aristotle (Physics [c.337 BCE], 218a18)
A Reaction
This implies that instants are abstractions, rather than physical realities. Aristotle rejects atoms, so presumably sees prime matter as the underlying uniter of matter. Insistence on linking the smallest parts leads to modern physics.
