Some two and a half years ago I previewed this paper. For several reasons, not least because of my faffing about and constantly reworking it in light of new reading, not to mention wrestling with some Quine and Frege, it only now has gone to press. Here are the first and last sections. Section II is entitled “KH and KT: Three Permutations” with sub-sections – KH and KT are Sui Generis: Ryle; KH As A Species of KT; The Agnostic View – Section III “Oakeshott on KH/KT: A Critique”; sub-sections “Will the Real Rationalist Please Stand Up?” and “Ryle and Oakeshott: A Discontinuity”; Section V “Tradition or Practice as an Extended Cognitive System” and finally Section V, some concluding remarks which I include here after section I.
I. The Social Nature of Rationality
Politics make a call upon knowledge. Consequently, it is not irrelevant to inquire into the kind of knowledge which is involved. — Oakeshott
Gilbert Ryle’s “Knowing How/Knowing That” distinction (KH/KT) gave crisp articulation to a long-standing epistemological concern that Michael Oakeshott had: that is, what is the epistemic status of the area that comprises our waking lives, the domain of practical reasoning, of which political practice, on Oakeshott’s account, is but one aspect.  This concern is set against a much broader purview: that of the nature of rationality, or more accurately the social nature of rationality.
Though Ryle’s KH/KT distinction has been taken to be primarily an epistemological distinction, it is as much a claim about the operations of the mind. Ryle’s The Concept of Mind  was a work in philosophical psychology; and though Oakeshott couldn’t be considered a philosopher of mind, his work is replete with concerns about the bipartite relationship of mind to world and of the bipartite relationship of theorizing to action. Oakeshott’s concern with the KH/KT distinction is coextensive with a concern with “unconsidered actions” supposedly “irrational” conduct and reflective consciousness, the latter supposedly the spring of rational conduct. On Oakeshott’s account the former is not irrational (where tradition is the only reliable resource, its disregard is irrational); the latter is illusory and hardly rational. The contrast is a spurious one; all there ever is, is a socially embedded intelligence – “intelligibility is contextual” – to use what might be considered an Oakeshott slogan. This said, Oakeshott does not subscribe to the Marx-Mannheim line (and their intellectual heirs comprising the sociology of knowledge movement) that human conduct can merely be explained as being subject to ‘‘false consciousness’’ or a distortive miscognition.
Oakeshott rejects the prevailing Cartesian orthodoxy across cognitive science, the philosophy of mind, epistemology and metaphysics: an orthodoxy that has systematically overlooked not only the location of thinkers in their physical environments, but has also overlooked the interactions amongst thinkers in the ambient socio-cultural soup:
You do not first have a mind, which acquires a filling of ideas and then makes a distinction between true and false, right and wrong, reasonable and unreasonable, and then, as a third step, causes activity. Properly speaking the mind has no existence apart from, or in advance of, these distinctions. These and other distinctions are not acquisitions; they are constitutive of the mind. The whole notion of the mind as an apparatus for thinking is I believe an error and it is the error at the root of this particular view of the nature of “rationality.” (RIP, 109-13)
For Oakeshott, a tradition or practice implies the social situatedness of the self and the rejection of focal individualism, the idea that human drives and behavioral characteristics are socially and historically invariant: individuals draw their self-understanding and their conceptions of the good, their “constitutive” ends, from what is conceptually to hand in historically specific societies or civilizations. Society is in some sense antecedent to the individuals that compose it. Mind does not merely respond to a given world; mind is enacted  through a particularized history of socio-environmental coupling: perception is an act of interpretation and the generation of meaning, a self that is embedded and has coherence in a matrix of practices and traditions. Situatedness, for Oakeshott, is captured in the following:
(i) Manners of behavior which are meaningless when separated from their context (RIP, 63);
(ii) “Politics may be said to be the activity of responding to conditions of things already recognized to be the product of choices” (RIP, 70, italics added);
(iii) “Human self-understanding is inseparable from learning to participate in what is called a ‘culture’” (VL, 16-17);
(iv) “Selves are not rational abstractions, they are historic personalities, they are among the components of [the] world of human achievements” (VL, 41).
Therefore, knowledge and cognition only exists against a background fabric of cultural possibility, a preexisting, complex web of linguistic, technological, social, political and institutional constraints — a social ecosystem if you like.  There is nothing external to a tradition in terms of which it can be appraised: an artless conduct is “as impossible as an utterance in no language in particular” (OHC, 86; RIP, 14). And again “Volition cannot carry us beyond thought, because there is no beyond” (EM, 26). A tradition fixes and applies its own internal criteria, methods, distinctions and standards of cogent argument, its own immanent standard of epistemic weight regarding its methodological, conceptual and empirical problems. Only from within a tradition-based politics can a tradition can be interrogated and applied. In Oakeshott’s terminology, it is to “pursue its intimations” or enter into a “flow of sympathy” (RIP, 57, 59, 60, 61, 129, 131) where there is no “changeless centre . . . everything is temporary but nothing is arbitrary” (RIP, 61). This means that one is always dealing with a reflective tradition, not an inert pattern of habitual behavior:
(i) “A human art is never fixed and finished; it has to be used and it is continuously modified in use” (VL, 13);
(ii) “A human being is a ‘history’ and he makes this history for himself out of his responses to the vicissitudes he encounters” (VL, 9; cf. VL, 63, passim);
(iii) “Practices are not stable compositions” (OHC, 100).
Later in On Human Conduct Oakeshott talks of a “practice” not as the outcome of a performance (OHC, 56) but as emerging and continuously invented: “an instrument to be played upon, not a tune to be played” (OHC, 58; cf. OHC, 91). In language reminiscent of Rationalism in Politics he writes: An agent’s understanding of a practice he or she is engaged in, “is not that of knowing the rules but of knowing how to speak it . . . “(OHC, 91; and cf. OHC, 26, where the theorist’s understanding is contrasted with the agent’s).
Tradition (or culture) is of such complexity, a complexity generated by infinitely fine-grained constantly shifting local and ephemeral variables, that as a guide to action, social knowledge (KH) cannot be reduced, abridged, or restated propositionally (KT) without remainder. Oakeshott’s conception of the KH/KT distinction manifests itself in two ways, the former I believe, morphed into the latter:
(i) Modality: Oakeshott’s idea that science, history, practice and aesthetics are domains constitutive of their own criteria of objectivity and standards appropriate to their own subject matter. Any attempt at cross- or trans-modal thinking is bound to be a corrupting exercise.
(ii) Political skepticism: the idea that politics has no intrinsic purpose or end; liberal society should properly be conceived as a civil association not an enterprise association. Social complexity will always defeat the calculation of efficient means (“scientific” politics) to clearly conceived, large-scale political ends. Aims are only incompletely accomplished and unforeseen side-effects always cause results to be markedly different from intentions. 
VI: Concluding Remarks
A history of thought is a history of men thinking, not a ‘history’ of abstract, disembodied ‘ideas’.  — Oakeshott
A more succinct and pointed statement of Oakeshott’s non-Cartesian credentials cannot be found. Oakeshott rejects the Cartesian bifurcation of the person into brain and body, apparent in the still prevailing methodological supposition that cognition can be studied independently of any consideration of the body and the physical and ambient social environment. Oakeshott’s emphasis on the notion of embodiment implies a goal driven and purposeful engagement with the world. The situated mind is enacted through a particularized history of socio-environmental coupling: perception is an act of interpretation and the generation of meaning, a kind of know how. Political philosophers would do well to see the broader relevance of Oakeshott’s epistemological concerns; situated cognitive science should now add Oakeshott to the roster theorists that include titans such as Heidegger, the later Wittgenstein, Merleau-Ponty and Hayek.

 Ryle’s “Knowing How, Knowing That” essay was first published in the Proceedings of the Aristotelian Society, New Series, Vol. 45 (1944 – 1945): 1-16. The terms “rationalism” and “knowledge of” and “knowledge about” make an appearance some thirty years earlier than the celebrated formulations of Rationalism in Politics in Oakeshott, Experience and its Modes (Cambridge: Cambridge Univ. Press, 1933), 23, 25, 53, 318. Hereafter: EM. The original essay “Rationalism in Politics” appeared in the Cambridge Journal, Vol. 1 (1947-8): 81-98, 145-57.

 The terms “enacted” or “enactive,” coined by Francisco J. Varela, Evan Thompson & Eleanor Rosch, The Embodied Mind: Cognitive Science and Human Experience (1991; reprint, Cambridge, MA: MIT Press, 2000), here implies sense-making, embodiment, emergence, and experience. Enacted in this sense is not co-extensive with Oakeshott’s term “self-enactment.” Oakeshott, On Human Conduct (Oxford: Clarendon Press, 1990), 70-8, passim. Hereafter: OHC.

 This is not an argument against all attempts at social change or improvement. For a Burkean, change is inevitable and desirable. As Burke said in Reflections on the Revolution in France, “a state without the means of some change is a state without the means of its conservation.” I am loath to use the term ‘conservative’ as it is a term that carries too many often incompatible connotations in Anglo-American philosophy (let alone in the public mind): there are self-avowed conservatives who are rationalists; the corollary is that not all anti-rationalists can be classed as conservative.
