“I did not write this work merely with the aim of setting the exegetical record straight. My larger target is those contemporaries who -- in repeated acts of wish-fulfillment -- have appropriated conclusions from the philosophy of science and put them to work in aid of a variety of social cum political causes for which those conclusions are ill adapted. Feminists, religious apologists (including "creation scientists"), counterculturalists, neoconservatives, and a host of other curious fellow-travelers have claimed to find crucial grist for their mills in, for instance, the avowed incommensurability and underdetermination of scientific theories. The displacement of the idea that facts and evidence matter by the idea that everything boils down to subjective interests and perspectives is -- second only to American political campaigns -- the most prominent and pernicious manifestation of anti-intellectualism in our time.”

“Many scientists espouse values or goals that, under critical challenge, they cannot characterize in a succinct and cogent way. They may be imprecise, ambiguous, or both. Such familiarly cited cognitive goals as simplicity and elegance often have this weakness, because most advocates of these goals can offer no coherent definition or characterization of them; indeed, it is probably not too wide of the mark to suggest that a major reason that most scientists purport to subscribe to the value of simplicity is why relatively few of them have anything very specific in mind. The imprecision of the concept allows for multiple interpretations; and in that fluid environment, almost everyone can devise a gloss on "simple" or "elegant" which he can find congenial. It should be clear why them charge of semantic utopianism, when warranted by the merits of the case, is a serious criticism of a goal, cognitive or otherwise. If someone purports to subscribe to an aim, but can neither describe it in the abstract nor identify it in concrete examples, there is no objective way to ascertain when that aim has been realized and when it has not. Values of that sort are too arbitrary to deserve any place in a rational activity.”
