Single Idea 13217

[filed under theme 27. Natural Reality / C. Space / 1. Void ]

Full Idea

Some philosophers thought what is must be one and immovable. The void, they say, is not: but unless there is a void what is cannot be moved, nor can it be many, since there is nothing to keep things apart.

Gist of Idea

The void can't exist, and without the void there can't be movement or separation

Source

report of Parmenides (fragments/reports [c.474 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 325a06

Book Ref

A Reaction

Somehow this doesn't seem very persuasive any more! I suppose we would distinguish various degrees of void, and assert the existence of sufficient void to allow movement and separation. We must surely agree that total nothingness doesn't exist.
