According to More and Parker, moral
reasoning principle # 1: If separate cases
aren’t different in any relevant way, then they
should be treated the same way, and if
separate cases are treated the same way, they
should not be different in any relevant way.
◦ AKA the consistency principle.
◦ Principle # 2: If someone appears to be violating
the consistency principle, then the burden of proof
is on that person to show that he or she is in fact
not violating the principle.
