Utilitarianism, as well as many other political and moral doctrines, presupposes that the problem of interpersonal utility comparisons can be solved. Otto Neurath gave a comparatively early (1912) and explicit statement of this problem, and he suggested that it cannot be solved. This may still be the dominant view. It is argued that recent attempts to solve the problem (by e.g. Schick, Rescher, Harsanyi, Brandt, Jeffrey, Arrow, and Hare) are unsatisfactory, but that the oldest suggestion - i.e. the method of minimal units or just-noticeable differences - is acceptable from the point of view of utilitarianism.

Presumably, most scientists believe that scientific knowledge is intrinsically good, i.e. good in itself, apart from consequences. This doctrine should be rejected. The arguments which are usually given for it — e.g. by philosophers like W.D. Ross, R. Brandt, and W. Frankena — are quite inconclusive. In particular, it may be doubted whether knowledge is in fact desired for its own sake, and even i f it is, this would not support the doctrine. However, the doctrine is open to counter-examples. The main counter-argument is that the doctrine has implications which are morally unacceptable.

Moral realism is defined here as the ontological view that there are moral facts. This is compared with traditional views in moral philosophy, such as naturalism, nonnaturalism, and noncognitivism. It is argued that we have no good reasons to avoid inconsistencies among our moral views unless (we believe that) moral realism is true. Various counter-arguments to this claim are criticized. Moreover, it is argued that, since we do not want to give up the practice of moral reasoning, we have a good reason to believe that moral realism is true.

Willard Van Orman Quine was born on 25 June 1908 in Akron, Ohio. For many years he was a professor of philosophy at Harvard University and is now emeritus. To some extent his views are connected with the American pragmatist tradition, but a more important influence comes from the empiricist tradition and, in particular, from the logical positivism of the Vienna Circle (see logical positivism). Quine has always remained faithful to the spirit of empiricism, but he has also criticized and revised the empiricist doctrine in important ways. He has published 20 books and numerous articles, and he is perhaps the most influential analytical philosopher of the second half of the twentieth century.
