I disagree, it tells us what change ontologically amounts to. — neomac
What on earth does that mean? What work is the word 'ontologically' doing?
I explained why it is circular. If you say 'change is when an object has a property at one time that it doesn't have at anotehr' then you have appealed to another change - a change in temporal properties - in your analysis of change. So it is circular. It is really no different to saying "bread is a substance made of bread" when the question is "what is bread?"
No it doesn’t. First of all, that definition of change makes no mention of predicates like “being present” and “being past“. — neomac
What? If an object goes from being present to being past, it has changed, has it not? Changed from being present, to being past. So it is no analysis of change to say "an object has changed when it has a property at one time that it does not have at another", for that's no more or less than to say that an object has changed in one respect when it has changed in another - true, but not an analysis of change.
Secondly, “being present” and “being past” may not be properties in strict sense. — neomac
Yes they are, and that would be irrelevant anyway, for you'd still be appealing to a change in your analysis of change.
A substantial answer to the question "what is change" must not make any mention of change or a synonym for change, otherwise it will be circular.
That's not necessarily a fault, incidentally - if we find we cannot analyze change without making mention of change or one of its cognates, then we have discovered that change is change and not another thing.
The point, though, is that my sensational analysis does not make mention of change and thus is substantial.
This sounds like a categorical confusion between “sensations” as an ontological type (the sensation of "red" is neither true or false) with “seeming” which is an epistemological type (what seems to be red can be blue so the red-seeming can be true or false). — neomac
You keep putting in extra words. What's a 'categorical' confusion as opposed to just a confusion?
Anyway, what you're doing is throwing mud at a wall and hoping some of it sticks. I have not said that sensations can be true or false, so why on earth do you think I am confused about the nature of sensations?
There are different sorts of sensation, and some of them are 'of' reality and thus are capable of being accurate or inaccurate. That's not true of all of them. A sensation of pain cannot be accurate or inaccurate. However, the impression that one is in pain can be. And similarly, my visual impression that there is a mug on my desk can be accurate or inaccurate.
The impression of change is like this - that is, it is capable of being accurate or inaccurate. It is accurate if there has been actual change, and not if not.
The point, though, is that the accuracy condition of a sensation is going to be another sensation. And thus, if change is something we have a sensation of, then change itself is a sensation.
