From me, referring to the easy visibility of the granularity
in the visual field:
I don't know if it's true of other people, but when I look at
a white wall I don't see continuity, I see granularity -- tiny
highly dynamic shimmering specks so small that they cannot be
made out individually, so small that you could fit a thousand
inside one of those tiny "floaters".
[15 arcseconds or less in angular resolution]
From (john baez):
Gosh darn, maybe this age-old continuity vs discreteness
argument boils down to differences in people's vision. I
can't make out those highly dynamics shimmering specks, maybe
because I'm nearsighted.
Acuity is not relevant, since it's not something you're looking AT, but
something you're looking THROUGH.
This only underscores the point made. If the normal person can't even
see the granularity in their own visual field, then that alone
impeaches them as valid witnesses on providing any first-hand testimony
on any presumed "first-hand" experience with the world as a continuum.
They got fooled into thinking that something was continuous which
should have been easily and obviously visible as being discrete and
granular -- which opens up the possibility that everything else they
*think* is continuous they're being fooled about too.
Maybe it's not within the capacity of a human being to directly
perceive the individual retinal activations in their visual field and
resolve angular resolution down to 15 arcseconds or less, as I assumed
and thought everyone else was already aware of at the time. But it's
well within my capacity.
