The problem for us (humanity) in discussing reality is that discussion can’t fuse with what it discusses, but that there instead forever will be a duality between them.
This duality means that theoretical singularities, like “the truth”, “the standard model” and “the true tree of Life”, are practical impossibilities.
This fact shows up as an impossibility to find a BOTH unambiguous AND consistent singularity. The problem is thus not practical in the common sense, but rather in the sense of fusing discussion with what it discusses.
This problem can thus be expressed as that “words can’t reach reality”.
