“Special” is a human concept which may not exist objectively, empirically. Distinct, unique, etc... are probably more honest, assuming that we don’t exist in a multiverse.
isn't every concept you could name right now a human concept which may not exist objectively?
No, but then, I like physics so I’d start rattling off fundamentals like the hyperfine transitions of Hydrogen, the speed of light in vacuum, and the mass of the proton.
Still can't prove those absolutely objective. They just work out with our human conceived models of the "physical" universe.
