27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
Atoms move themselves [Lucretius]
     Full Idea: Atoms move themselves.
     From: Lucretius (On the Nature of the Universe [c.60 BCE], II.133)
     A reaction: Something has to move itself, I suppose, but then that could be psuché, giving us free will (see Idea 1424). Why does Epicurus need the 'swerve' if atoms are self-movers? See Idea 5708.
If there were no space there could be no movement, or even creation [Lucretius]
     Full Idea: We see movement everywhere, but if there were no empty space, things would be denied the power of movement - or rather, they could not possibly have come into existence, embedded as they would have been in motionless matter.
     From: Lucretius (On the Nature of the Universe [c.60 BCE], I.342)
     A reaction: This still seems a good argument, if reality is made of particles. People can move in a crowd until it becomes too dense.
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / d. Entropy
It is quicker to break things up than to assemble them [Lucretius]
     Full Idea: Anything can be more speedily disintegrated than put together again.
     From: Lucretius (On the Nature of the Universe [c.60 BCE], I.558)
     A reaction: Clearly the concept of entropy was around long before anyone tried to give a systematic or mathematical account of it.
