it has long been assumed that science is an essentially unified endeavor. It has seemed reasonable to talk of a scientific method, well define set of procedures and practices that could in principle be applied to many different scientific disciplines and to speculate on the prospect of some kind of grand unification of the sciences, in which all laws and principles would somehow collapse into an overarching, exhaustive and internally consistent structure. The key to such a coming-together is supposedly a fully reductive account of the science, the usual suggestion being that everything will ultimately be subsumes under physics. REcent work, however, has brought a fuller appreation of the cultural and social embeddedness of the sciences and a greater emphasis on the essential disunity of sciences. And with it has come a realization that the search for a single scientific method is probably chimercial.
