This paper compares Hayek and Polanyi on spontaneous social order. Although Hayek is widely believed to have first both coined the name and explicated the idea of ?spontaneous order?, it is in fact Michael Polanyi who did so. Numerous differences emerge between the two thinkers. The characterisation of spontaneous order in Hayek, for example, involves different types of freedom to those advanced by Polanyi. Whereas Hayek (usually) portrays spontaneous order as a single entity, which is equivalent to free society as a whole ? the free?catallactic society ? Polanyi by contrast is disposed to conceive of spontaneous orders as sub?units or components within free society as a whole. These and other aspects of their thought ? including the distinction between spontaneous and planned social orders ? are reviewed and criticised

Celebrated as a theorist of science, and a source of stimulating ideas for theologians and philosophers of religion, Michael Polanyi explicitly denied cognitive relativism. Yet cognitive relativism, this paper suggests, is implied by Polanyi's account of conceptual frameworks and intellectual controversies.In ‘The Stability of Beliefs’ Polanyi understands conceptual frameworks as embedded in, and as expressed in the use of, their own languages. The language‐with‐theory limits the range of discussable subjects, interprets relevant facts in its own terms, permits only certain questions to be asked, with answers to these questions serving to confirm the framework.In Polanyi's masterwork, Personal Knowledge , these ideas inform his discussion of controversies over scientific frameworks and frameworks vying to become part of science. In each controversy, frameworks are logically disconnected, Polanyi foreshadowing the incommensurability thesisI argue that Polanyi's ideas satisfy recognised criteria of cognitive relativism. Perception is undetermined by objects and conditioned by language. Empirical propositions, in Polanyi's view, are accepted as true only within a conceptual framework. Polanyi regards supporters of logically disconnected frameworks as thinking differently, living in different worlds, speaking different languages and as experiencing communication failure. There is no framework‐independent argument or evidence to distinguish any framework as the best available approximation to the truth. Frameworks are logically disconnected and incommensurable

Michael Polanyi and Karl Popper offer contrasting accounts of social tradition. Popper is steeped in the heritage of the Enlightenment, while Polanyi interweaves religious and diverse secular strands of thought. Explaining the liberal tradition, Polanyi features tacit knowledge of rules, standards, applications and interpretations being transmitted by “craftsmen” to “apprentices.” Each generation adopts the liberal tradition on “faith,” commits to creatively developing its art of knowledge-in-practice, and is drawn to the spiritual reality of ideal ends. Of particular interest to Popper is the rationality of social traditions. Likened by him to scientific theories, Popper’s traditions are criticizable and improvable, assisting agents to understand, and act in, the world as stable and predictable. Polanyi’s is the more informative rendering of tradition. Polanyi delves deeply into important areas where Popper only scratches their surface: the tacit dimension, transmission by way of apprenticeship, the meaning of tradition for those who participate in it, and the extent of its authority over them.

It is a testimony to the enduring importance of Thomas Kuhn's The Structure of Scientific Revolutions that, 30 years on, its doctrines of normal science and paradigm, incommensurability and revolution continue to challenge metascien tists and stimulate vigorous debate. Critique has mainly come from philosophers and historians; by and large, interested sociologists have embraced Kuhn. Un justifiably so, this article argues, bringing to light a serious difficulty or "anom aly" in his account of the social side of science. Contrary to what he claims, scientific knowledge is not the achievement of organic communities. It is con structed in "trans-epistemic arenas" by diverse participants, laypeople, and specialists. Accepting "community" is a flawed concept in the sociology of science, and in appreciating the major role Kuhn assigned it, the Kuhnian system looks less robust than it did before.

This paper is designed to reinterpret and clarify John Stuart Mill's ideas on science. Past discussions of these ideas strike me as unsatisfactory in two crucial respects. In the first place they have encouraged us to regard Mill's principal work on epistemology, A System of Logic, as fundamentally inductivist This is the received interpretation of Mill's Logic and one finds it summarized and affirmed in the remark of Laurens Laudan that 'by and large' Mill was 'a rather orthodox inductivist who saw science as the generalisation of observation and who argued that all scientific ideas come directly from experience.

Michael Polanyi argues in Personal Knowledge (1958) that conceptual frameworks involved in major scientific controversies are separated by a `logical gap'. Such frameworks, according to Polanyi (1958: 151), are logically disconnected: their protagonists think differently, use different languages and occupy different worlds. Relinquishing one framework and adopting another, Polanyi's scientist undergoes a `conversion' to a new `faith'. Polanyi, in other words, presaged Kuhn and Feyerabend's concept of incommensurability. To what influences was Polanyi subject as he developed his concept of the logical gap? The answer, as unfolded in this article, is twofold: Evans-Pritchard's Witchcraft, Oracles and Magic among the Azande and the Confessions of St Augustine

Between 1945 and 1948, Michael Polanyi, Michael Oakeshott, and Karl Popper respectively discussed the nature of tradition, and the part that traditions play in free societies. This article analyzes these thinkers’ ideas of tradition. Polanyi depicted tradition as knowledge that is embodied in skilled practice, and tradition for Oakeshott consists in activities that are suffused with practical knowledge and technique. Popper emphasized rational criticizability, whereas Polanyi and Oakeshott emphasized the tacit dimension of traditions

Locke scholars continue to disagree over how he analyzed natural laws, real essence-power relations in physical substances. Some say he regarded them as emanations, necessitated by the corpuscular structure of real essences; for others his laws are adventitious, imposed on substances by God and contingent on divine alterable will. The second view has been increasingly favored in recent years, assisted no doubt by Edwin McCann's potent case for it in "Lockean Mechanism" (1985). The present article, whose authors are sympathetic to the necessitarian reading of Locke, argues against McCann's exegesis.

Born in 1918 in New York, awarded a doctorate in analytical chemistry (1944), Leonard K. Nash enjoyed a distinguished career at Harvard, holding a chair of chemistry from 1959 to 1986. Conducting research in thermodynamics and statistical mechanics, Nash authored successful textbooks, some of which remain in print (e.g. Elements of Chemical Thermodynamics, and Elements of Statistical Thermodynamics).This essay describes the theory of science that Nash developed in a book he published in 1963, The Nature of the Natural Sciences. The present author is of the view that Nash's neglected theory is worth retrieving, as one that is likely to kindle the interest of historians of metascience on several counts. Part of ..

It has been said that Robert Boyle gave in the century of The Scientific Revolution the “fullest expression” of the view that laws of nature are continually impressed by God (“occasionalism”). So regarded, the universe is anything but an autonomous machine, its ordered operation depending on God’s continuous imposition of lawful, patterned relations between phenomena and his continuous provision of motion for them to actually enter relations. The present paper contests this treatment of Boyle. Evidence is elicited to show that, for Boyle, most physical relations issue from intrinsic dispositions of phenomena, not divine impositions, dispositions determined by corpuscular textures. Members of classes of phenomena have capacities to make specific changes which members of other classes have capacities to receive, these correlative capacities being necessarily connected, subjects in principle of a priori synthetic necessary knowledge. The same view is found in John Locke’s Essay Concerning Human Understanding. It is additionally argued that Boyle’s God, the quintessentially active being, imparted motion at the creation, whereafter the motion of (at least most) natural phenomena has derived from natural, not supernatural, impulsion.
