V-2nd. our "field of vision"...passim, Chap 1

[Mark Kohut]

Wittgenstein, a philosopher we know TRP had read, used the concept of field of vision. Simplistically, it is the world we see, all that is the case" in that oft-quoted (inclu TRP) line.--He drew meanings out of his observation that the eye IS NOT in the field of vision. It, in some way, is that field. ( He infamously also said/wrote that Solipsism was true but could not be said: that is, again simplistically fer sure, the world IS our field of vision too.  See below.

Wittgenstein uses, as an analogy, the field of vision. Our field of vision does not, for us, have a visual boundary, just because there is nothing outside ...

For Wittgenstein, I take it, a field of vision has no shape, and we only feel that that's strange because we are in the grip of a model of vision as inner photography. It's actually something else entirely.

Also, this spatial unlimitedness later is akin to some reflections on Time. To come.
