35 alternative positions, have, for the first time in decades, put those who reject objectivism in ethics on the defensive. On What Matters is a book of daunting length: two large volumes, totaling more than 1,400 pages, of densely argued text. But the core of the argument comes in the first 400 pages, which is not an insurmountable challenge for the intellectually curious — particularly given that Parfit, in the best tradition of English-language philosophy, always strives for lucidity, never using obscure words where simple ones will do. Each sentence is straightforward, the argument is clear, and Parfit often uses vivid examples to make his points. Thus, the book is an intellectual treat for anyone who wants to understand not so much “what matters” as whether anything really can matter, in an objective sense. Many people assume that rationality is always instrumental: reason can tell us only how to get what we want, but our basic wants and desires are beyond the scope of reasoning. Not so, Parfit argues. Just as we can grasp the truth that 1 + 1 = 2, so we can see that I have a reason to avoid suffering agony at some future time, regardless of whether I now care about, or have desires about, whether I will suffer agony at that time. We can also have reasons (though not always conclusive reasons) to prevent others from suffering agony. Such self- evident normative truths provide the basis for Parfit’s defense of objectivity in ethics. One major argument against objectivism in ethics is that people disagree deeply about right and wrong, and this disagreement extends to philosophers who cannot be accused of being ignorant or confused. If great thinkers like Immanuel Kant and Jeremy Bentham disagree about what we ought to do, can there really be an objectively true answer to that question? Parfit’s response to this line of argument leads him to make a claim that is perhaps even bolder than his defense of objectivism in ethics. HOUSE_OVERSIGHT_031910
