These papers are all written from what is called a realist perspective. The statements of science are in my view either true or false (although it is… - Hilary Putnam

Why, then, is semantics so hard? In terms of the foregoing, I want to suggest that semantics is a typical social science. The sloppiness, the lack of precise theories and laws, the lack of mathematical rigor, are all characteristic of the social sciences today. A general and precise theory which answers the questions (i) why do words have the different sorts of functions they do? and (2) exactly how does conveying core facts enable one to learn the use of a word? is not to be expected until one has a general and precise model of a language-user; and that is still a long way off. But the fact that Utopia is a long way off does not mean that daily life should come to a screeching halt. There is plenty for us to investigate, in our sloppy and impressionistic fashion, and there are plenty of real results to be obtained. The first step is to free ourselves from the oversimplifications foisted upon us by the tradition, and to see where the real problems lie. I hope this paper has been a contribution to that first step.

In closing, I can only apologize for not having given any positive account of either mathematical truth or mathematical necessity. I can only say that I have not given such an account because I think that the search for such an account is a fundamental mistake. It is not that there is nothing special about mathematics; it is that, in my opinion, the investigation of mathematics must presuppose and not seek to account for the truth of mathematics. But this is the beginning of another paper and not the end of this one.

Part of what makes moral philosophy an anachronistic field is that its practitioners continue to argue in this very traditional and aprioristic way even though they themselves do not claim that one can provide a systematic and indubitable 'foundation' for the subject. Most of them rely on what are supposed to be 'intuitions' without claiming that those intuitions deliver uncontroversial ethical premises, on the one hand, or that they have an ontological or epistemological explanation of the reliability of those intuitions, on the other.
