27. Natural Reality / B. Modern Physics / 1. Relativity / a. Special relativity

12709	Motion is not absolute, but consists in relation [Leibniz]
	Full Idea: In reality motion is not something absolute, but consists in relation.
	From: Gottfried Leibniz (On Motion [1677], A6.4.1968), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 3
	A reaction: It is often thought that motion being relative was invented by Einstein, but Leibniz wholeheartedly embraced 'Galilean relativity', and refused to even consider any absolute concept of motion. Acceleration is a bit trickier than velocity.
