Another brief “hold that thought” post.
My own metaphysics is based around atomic quantum points that I think of as truly Democritan atoms – genuinely indivisible, inconceivably divisible “a-toms” – without any parts or even properties of their own. Everything of any significance in the world – everything full-stop – is about relations between these.
What I know now, thanks to a question in the University Challenge final last night, is that Euclid defined his conception of a point as
“a point is … that which has no part”
‘Twas ever thus. Nothing hew under the sun.
(Democritus preceded Euclid but was still living when the latter became active?)
