15885 | The necessity of Newton's First Law derives from the nature of material things, not from a mechanism [Harré] |
Full Idea: The 'must' of Newton's First Law is different. There is no deeper level relative to the processes described to give a mechanism which generates uniform motion. There is no such mechanism. ..It specifies what it is for something to be a material thing. | |
From: Rom Harré (Laws of Nature [1993], 4) | |
A reaction: Harré says the law can only exist as part of a network of other ideas. |
