Is “If P, then Q. P. Therefore, Not-Q.” also just as basic and elemental an error as “P is Fermat’s Last Theorem. Therefore, P is false.”?
No, it’s far more basic. “Fermat’s Last Theorem” is a very complicated concept which is only being referenced here. The full logical description of the concept—which is what’s necessary to evaluate the argument—would be much longer.
