ABSTRACT
Is there a perceptual reality of time? When I look at the hourglass, I do not see time, I just infer it. Literally, what I see in a noninferential way is a dynamic event flow that unfolds in space, the sand particles rushing under the invisible force of gravity. I see the duration and agitation of this flow from beginning to end. From it, I may infer time like I may infer gravity or quantity. But those are in essence mental constructs, the products of my imagination, not the direct product of what impinges on my senses. To that extent, time is more illusory than real. What is real about time, however, is that for us it is finite. That is real real.
