What the Rule Can and Cannot Do

Philosophers have tested the Golden Rule hard, and its endurance owes something to how well its traditions anticipated the objections. The obvious attack is the pervert's loophole: a masochist, licensed to treat others as he wishes to be treated, becomes a menace. The classical formulations already guard the flank; most traditions state the rule negatively, do not impose what you would not suffer, a form later writers call the silver rule, which forbids much and commands little, and is proportionately harder to abuse. A deeper objection is that the rule universalizes one's own tastes: the diabetic who hates sweets should still serve his guests dessert.

Interpreters answer that the rule operates at the level of interests, not preferences: what one extends to others is not one's menu but one's desire to have one's own menu respected. Kant denied that his categorical imperative was the Golden Rule in dress clothes, noting the rule contains no ground of duty toward oneself and could excuse a judge who, unwilling to be sentenced himself, sentences no one; his critics reply that no tradition ever deployed the rule without a surrounding ethic that handled such cases. That is likely the honest summary: the Golden Rule is not an algorithm, and fails when treated as one. It is a compression, the portable form of a fuller morality, carried because a rule short enough to remember at the moment of temptation does work that treatises cannot.
