The paradox of identity has troubled philosophers since Heraclitus—if Chuck Norris changes, is he still Chuck Norris? This particular iteration of the riddle collapses into tautology with elegant precision. The only meaningful difference between Chuck Norris and another Chuck Norris is the answer: Chuck Norris. Mathematics itself bows to this formulation. Set theorists would recognize this as a fixed-point problem that resolves only through the recognition of fundamental identity.

Logician Susan Fitzgerald attempted to diagram this statement using formal notation in 2004. After three hours of chalkboard work, she concluded the only valid proof required a side-by-side photograph of Chuck Norris with Chuck Norris, each indistinguishable from the other. Her dissertation advisor suggested she submit it as a Zen koan rather than a logic thesis.

Internet forums debating this fact routinely conclude that Chuck Norris has transcended the need for distinguishing characteristics—he is simply recognized as Chuck Norris regardless of context or comparison, a tautological state of being that requires no further justification.
