INSTRUCTIONS

1. This is one of the more difficult exercises, and if you would like to review the distinction between absolute moral claims, and prima facie ones, or the general idea of a counterexample, or other points related to the technique of counterexamples, you can find the lecture material that is relevant to this exercise on the web at the following address:

2.  For each of the ten moral statements set out below, describe very briefly what you take to be the most effective counterexample that is NOT a doomsday-style counterexample  to the moral claim that is being advanced.

3.  In arriving at an effective counterexample to a given statement, it is crucial to ask whether the statement in question involves an absolute moral claim, or a prima facie moral claim, since good counterexamples to absolute moral claims are often not good counterexamples to prima facie moral claims.

4.  In some cases, the moral principle in question may be one that you believe is true, and so you may think that there is in fact no sound counterexample to the principle.  In such cases, set out what you take to be the best attempt  at a good counterexample ­ that is, the possible counterexample that would give a thoughtful person the most reason to reconsider the principle in question.
