[speed of the passing of time]

6 ideas
If time involved succession, we must think of another time in which succession occurs [Kant]
     Full Idea: If one were to ascribe succession to time itself, one would have to think yet another time in which this succession would be possible.
     From: Immanuel Kant (Critique of Pure Reason [1781], B226/A183)
     A reaction: The implication of this might be that while we must believe that time exists, we are utterly incapable of imagining its existence.
If time flows, then 'how fast does it flow?' is a tricky question [Smart]
     Full Idea: If it is said that time flows, then it seems that the question 'how fast does it flow?' is a devastating one for the A-theorist.
     From: J.J.C. Smart (The Tenseless Theory of Time [2008], 5)
     A reaction: This is one of the basic landmarks in any debate on time. Time can't be understood by analogy with anything else (such as a river) it seems.
Time can't speed up or slow down, so it doesn't seem to be a 'process' [Le Poidevin]
     Full Idea: Processes can speed up or slow down, but surely the passage of time is not something that can speed up or slow down?
     From: Robin Le Poidevin (Travels in Four Dimensions [2003], 08 'Mystery')
     A reaction: If something is a process we can ask 'process of what?', but the only answer seems to be that it's a process of processing. So it is that which makes processes possible (and so, as I keep saying) it is best viewed as a primitive.
If time passes, presumably it passes at one second per second [Maudlin]
     Full Idea: It is necessary and, I suppose, a priori that if time passes at all it passes at one second per second. …Similarly, the fair exchange rate for a dollar must be a dollar.
     From: Tim Maudlin (The Metaphysics within Physics [2007], 4.1)
     A reaction: [He is discussing Huw Price on time] This is a reply to the claim that if time passes it has to pass at some rate, and 'one second per second' is ridiculous. Not very convincing, even with the dollar analogy.
What is time's passage relative to, and how fast does it pass? [Bardon]
     Full Idea: If time is passing, then relative to what? How could time pass with respect to itself? Further, if time passes, at what rate does it pass?
     From: Adrian Bardon (Brief History of the Philosophy of Time [2013], 4 'Pervasive')
     A reaction: I remember some writer grasping the nettle, and saying that time passes at one second per second. Compare travelling at one metre per metre.
It is meaningless to measure the rate of time using time itself, and without a rate there is no flow [Baron/Miller]
     Full Idea: It seems we are forced to measure the rate of time's passing against itself. But that's just not a meaningful rate. So time has no rate. So it doesn't flow. So there is no such thing as temporal passage.
     From: Baron,S/Miller,K (Intro to the Philosophy of Time [2019], 2.3.1)
     A reaction: It is suggested that you can exchange dollars one for one, so time might move at one second per second. But you can't exchange your own dollars with yourself at one-for-one. That is meaningless. Time is NOT a substance which flows.
