In the history of Western philosophy, there has long been debate over the nature of science. Professor Paul Feyerabend, in his 1975 work Against Method, asserts that the borders between science and nonscientific ideas such as witchcraft, magic and astrology are illusory-there is no substantive difference or clear boundary between science and non-science.
在西方哲學史上，對於何謂「科學」有很長遠的辯證，七○年代，美國加利福尼亞大學教授保羅・費耶阿本德在其代表作《反對方法》中甚至斷言：科學與巫術、魔法、占星術等非科學的界限「已化為煙雲」，不存在任何實質上的差別。
