I'm not saying time isn't required for perception. I'm only saying your eyes can see just one point along its axis at any given moment. So you can't say that eyes (or other known human senses) are capable of seeing along this axis. That's what I mean when I say that dimension isn't "immediately accessible".
note that in actuality you are perceiving a zillion different points in time "
at once"
- trivially different points in time for things up close, but when you look into the sky at night, you see the clouds as they were noticably more recently than the moon was, and you the scale becomes brain sploding when you compare that you how far back in time you're seeing the stars and other galaxies and stuff.
of course, you knew that.

your two retinas are 2-D individually, but the optical processing part of your brain is always responding to both at once. more than the illusion of 3-D, it's impossible for you to think about things without doing differential viewing - you cannot escape back to the individual retinas and just think about them.
moreover, the brain does not process each "
quantized instant of retinal viewing"
fully before going to the next - it's not like staring at a single film frame and understanding it fully before looking at the next one. experiments have shown that sometimes what you "
saw"
was retroactively altered by other thoughts or subsequent images.
your eyes flick around in motions called staccades faster than your brain can "
finish perceiving"
a single image. these feed dimensions of motion and space to your brain.
while your retinas contain a 2-D image, you literally cannot "
think"
about those captures - you ONLY perceive a world full of motion (i.e. time) and three-dimensionality.
I'm not being coherent here. I should just refer to Consciousness Explained by Dan Dennett and move on.
