Dear Akinbo:
Thanks for your interest!
-----------------------------------------
"In your ETS representation,
- is a point a geometric fiction or a physically real object with extension, (monad)?
- can a line have length with zero breadth?
- can a surface having length and breadth but with a zero thickness still exist physically?
- can abstract objects, existing only in the Platonic realm form a part of a physically real object in this physical realm? (Noting that by Euclid's definitions, the extremities of physically real bodies are surfaces, and if lines physically exist, their extremities are points)."
-------------------------------------------
Please note that ETS says nothing about "Euclid's definitions" As to your last question, please see the concept of instantiation in the essay.
Best wishes, Lev
