I once had the chance to talk to a famous mathematician & I mentioned optical illusions. Him: But *all* vision is an illusion.

Sounds like a different thing. To do with the wave nature of light. Wavelength bigger than particle spacing.
@Intrinsic29 -
Is it? I thought it might be relevant coz it explained why its more useful for us to see things as they aren't.

It's complicated! But we can't see through things cos of the properties of light. Light waves have a size.
@Intrinsic29 -
When that size is bigger than the spacing between particles, it's too big to pass through. (Simplified for Twitter)
@Intrinsic29 -
OK, so a different reason for it appearing solid than because it was useful for us to see it that way.
