I'm a little confused as to why. 1+1=2 is the result of the
application of mathematical axioms. Is the existence of such
axioms a deterrent to objectivity? Law of Excluded middle is
also a good moral. it is a good morality of certain forms of
Logic.
"This cannot [x] because [y]"
You're applying morality. Heuristics. If I had to dispense of
rules and standards and was allowed only one to apply to all
disciplines, it's heuristics. But I am a pragmatist at heart.
