[relationship between time and physical change]

5 ideas
Unlike time, change goes at different rates, and is usually localised [Aristotle, by Le Poidevin]
     Full Idea: Aristotle says time could not be the same thing as change, for first change can go at different rates, but not so time, and secondly change is confined to a part of space whereas time is universal.
     From: report of Aristotle (Physics [c.337 BCE], 218b11-) by Robin Le Poidevin - Travels in Four Dimensions 02 'As Change'
     A reaction: The observation that the speed of change varies seems to need a belief in uniform time. Le Poidevin doubts Aristotle's objections, because the theory concerns change in general, and not particular instances of it.
I disagree with the idea that time is nothing but cosmic movement [Augustine]
     Full Idea: I once heard a learned man say that time is nothing but the movement of the sun and the moon and the stars, but I do not agree.
     From: Augustine (Confessions [c.398], XI.22)
     A reaction: It is tempting to say that you either take time or movement as axiomatic, and describe one in terms of the other, but you are stuck unable to give the initial statement of the axiom without mentioning the second property you were saving for later.
It seems hard to understand change without understanding time first [Bardon]
     Full Idea: It is very tough to see how we could understand what change is without understanding what time is.
     From: Adrian Bardon (Brief History of the Philosophy of Time [2013], Intro)
     A reaction: This thought is aimed at those who are hoping to define time in terms of change. My working assumption is that time must be a primitive concept in any metaphysics.
We experience static states (while walking round a house) and observe change (ship leaving dock) [Bardon]
     Full Idea: We make a fundamental distinction between perceptions of static states and dynamic processes, …such as walking around a house, and watching a ship leave dock.
     From: Adrian Bardon (Brief History of the Philosophy of Time [2013], 2 'Kantian')
     A reaction: This seems to be a fundamental aspect of our mind, rather than of the raw experience (slightly supporting Kant). In both cases we experience a changing sequence, but we have two different interpretations of them.
Static time theory presents change as one property at t1, and a different property at t2 [Baron/Miller]
     Full Idea: The static theory of time appeals to an 'at-at' notion of change, which analyses change as objects or events having one property at time t1, and a different property at t2. (The worry about this is that it describes variation, but not real change).
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 1.4)
     A reaction: I suppose observing a different property at t2 is observing the result of a change, rather than the process. But then the process might be broken down into micro-gradations of properties. Maybe only results can be observed.
