🔬 MCAT Exam Prep

An author argues that moral relativism leads to a paradox: if all moral systems are equally valid, then one cannot criticize any practice. This is an example of:

A Ad hominem attack
B Reductio ad absurdum — showing a position leads to an unacceptable conclusion
C Straw man
D Appeal to authority

✓ Correct Answer: Option B

By showing that moral relativism leads to the inability to condemn harmful practices (an absurd conclusion), the author uses reductio ad absurdum.
