保羅·費耶阿本德（1924-），蜚聲當代英美科學哲學界的一位批判傢。他嚮邏輯實證主義和批判理性主義的方法論提齣瞭挑戰，並由曆史主義哲學中的相對主義走嚮認識論的無政府主義和方未能論的多元主義。

No study in the philosophy of science created such controversy in the seventies as Paul Feyerabend s Against Method. In this work, Feyerabend reviews that controversy, and extends his critique beyond the problem of scientific rules and methods, to the social function and direction of science today. In the first part of the book, he launches a sustained and irreverent attack on the prestige of science in the West. The lofty authority of the expert claimed by scientists is, he argues, incompatible with any genuine democracy, and often merely serves to conceal entrenched prejudices and divided opinions with the scientific community itself. Feyerabend insists that these can and should be subjected to the arbitration of the lay population, whose closes interests they constantly affect as struggles over atomic energy programs so powerfully attest. Calling for far greater diversity in the content of education to facilitate democratic decisions over such issues, Feyerabend recounts the origin and development of his own ideas successively engaged by Brecht, Ehrenhaft, Popper, Mill and Lakatos in a spirited intellectual self-portrait. Science in a Free Society is a striking intervention into one of the most topical debates in contemporary culture and politics.
