Is Change Possible? Suppose, you are something that exists at time 12 pm. Once it is 12:01 pm, the guy (you), which existed at 12 pm is non-existent now. — elucid
I guess that would be true.
Yes, but that square is not a circle, they are two different things.
Right.
This is my explanation for why change seems to exists even though things that tell us that it is not possible exist. I will use a circle and a square in this example. I will guess that a circle becoming a square is impossible, but a circle becoming non-existent and a square appearing is possible, making it seem like a circle became a square. — elucid
I think the problem with this is not that there would be no circle at one point (or that we would be dead), but that the circle would have to stop existing, and that the square would have to start existing. But let's say we grant that. It seems the time between the circle's non-existence and the square's existence is indifferent. How long do I, the guy that exists at 12 pm, exist before I become the next guy? Maybe you didn't really mean "a circle becoming non-existent and a square appearing is possible" and you just happened to say it that way.
Statement 1 in your first post says,
"A circle is
never the same as anything that is not a circle."
If a circle must be a circle and cannot be something else, time is irrelevant. I mean, you could omit all time-related words and say,
"A circle is the same as anything that is not a circle. Therefore a circle is something that is not anything that is not a circle."
"Something existent is not the same as something non-existent. Therefore, something existent is something that is not non-existent."
A circle would be a-temporal, the same way a man is, the same way something existent is, the same way something non-existent is, etc.
