I see how paradoxes can extend logic, contrary to how they were traditionally viewed, as destructive to logic. — Agent Smith
You got it! Yes. That's the gist of my argument. — ucarr
So back to my original question, what are dimensions doing in set theory? What is a dimension here? — Banno
...the set of all sets not members of themselves. — ucarr
You got it! Yes. That's the gist of my argument. — ucarr
:lol: I'm not sure how exactly though. — Agent Smith
Striking resemblance to paraconsistent logic I must say. However, wouldn't the analogy work better if we take two things rather than one thing doing weird stuff in spacetime? — Agent Smith
I'm afraid I don't understand where the paradox is in 4D hypercubes. Let's simplify for a moment to better visualize the problem. A 2D square has 1D boundaries (lines) in 4 different locations, meeting at the edges. This is the same relationship that a 3D cube has with its 2D sides, and that a 4D hypercube has with its 3D sides.Since a hypercube, being 4D, has 3D boundaries, it occupies four distant 3D locations, i.e., the same object in four places simultaneously. This type of spatial expansion, i.e., spatial dimension, deals a fatal blow to logical consistency at the level of 3D spatial expansion. At the level of 4D spatial expansion, logical consistency, i.e., one object being in two places at once is natural not fatal. — ucarr
Are you perhaps talking about, say, an interaction between two hypercubes? — ucarr
We can take this paradox and cast it into another, equivalent form: being in two places at the same time which means an object is simultaneously itself and not itself. — ucarr
A very stretched metaphor, at best; not an equivalence. — Banno
Russell's paradox lead to further developments in logic, not to its demise. — Banno
I'm afraid I don't understand where the paradox is in 4D hypercubes. — PhilosophyRunner
:up: You seem to be on the right track given what I know. — Agent Smith
