Time, How Confusing Indeed!

I was discussing dimensions with my youngest son Pascal (age 8). He had said that a 3 dimensional world must be as confusing for a 2 dimensional being as a 4 dimensional world is for a 3 dimensional being like us. True, I said, but did you know that we really live in a 4 dimensional world. Do you know what the fourth dimension is? Pascal thought about it but couldn't figure out what might be the fourth dimension.

Time, I said. Time is the fourth dimension. Without time I don't know that we would experience anything. It really is the first dimension, not the last and fourth.

"Time, yeah", said my son. He paused.

"Time is very confusing!" he exclaimed. "How did time get created? How could it have started without time existing".

 Yes, Indeed. Very confusing. Eternally confusing. When Pascal presented his older brother Julien (age 13) with this conundrum, his brother said that there are certain things that we cannot understand. That we will never understand.

 Is Julien right? Does time demark the intrinsic ends of epistemology?
