9635 | Given atomism at one end, and a finite universe at the other, there are no physical infinities [Brown,JR] |
Full Idea: There seem to be no actual infinites in the physical realm. Given the correctness of atomism, there are no infinitely small things, no infinite divisibility. And General Relativity says that the universe is only finitely large. | |
From: James Robert Brown (Philosophy of Mathematics [1999], Ch. 5) | |
A reaction: If time was infinite, you could travel round in a circle forever. An atom has size, so it has a left, middle and right to it. Etc. They seem to be physical, so we will count those too. |
5950 | If only atoms exist, how do qualities arise when the atoms come together? [Plutarch] |
Full Idea: If you accept atomism, you must show how bodies without quality have given rise to qualities of every kind by the mere fact of coming together. For example, how has the quality called 'hot' been imposed on the atoms? | |
From: Plutarch (74: Reply to Colotes [c.85], §1111) | |
A reaction: This argument is still significant in current philosophy of mind. If temperature is 'mean kinetic energy', you are left wondering where the energy came from, and why minds experience the heat. This is the 'Hard Question'. |
