Happy birthday Google

11th_birthday

Brin and Page:

We assume page A has pages T1, . . ., Tn which point to it (i.e., are citations). The parameter d is a damping factor which can be set between 0 and 1. We usually set d to 0.85, . . ., C(A) is defined as the number of links going out of page A. The PageRank of a page A is given as follows:

PR(A) = (1-d) + d (PR(T1)/C(T1) + … + PR(Tn)/C(Tn))

Google’s search algorithm is a refinement of degree centrality, namely eigenvector centrality, where degree centrality is something we touched upon in the last section when discussing testimony, trust and authority. Eigenvector centrality gives credence to the idea that not all connections should be equally weighted. Google’s Page-Rank (PR) is a star example of eigenvector centrality, and is a direct descendant of the citation system used in traditional librarian science, the most familiar being journal rankings. The more citations other documents make to a particular document, the more ‘‘important’’ a given document is and the more status accorded to a journal through aggregation techniques. In much the same way, Google’s PR algorithm assesses the importance or relevance of a Web page. Search engines are, as Christophe Heintz puts it, ‘‘reputation systems’’ (EigenTrust algorithms) in that they ostensibly promote epistemic and cognitive worth (Heintz, 2006). PR’s power lies in its ability to solve an equation with over 500 million variables and 2 billion terms. Its simplicity lies in its assessing a page’s importance by counting backlinks as a traditional technique of library science objectivity.

Ryle & Oakeshott on the “Knowing-How/Knowing-That” Distinction

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.[1]                                  — 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. [2] 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 [3] 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 [4] 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)[5];

(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. [6] 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. [7]

 

VI: Concluding Remarks

A history of thought is a history of men thinking, not a ‘history’ of abstract, disembodied ‘ideas’. [49] — 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.

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.

[4] 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.

[7] 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.

Key Terms in Philosophy of Mind

Pete Mandik is trailing his forthcoming book – Key Terms in Philosophy of Mind - to be published by Continuum. From what I’ve read of Pete’s work, he always offers a reliable hard-nosed account of issues in the philosophy of mind and is very up on the literature – he is not stuck in rehashing philosophy of mind circa 1989 – as it seems some are apt to do. An added bonus to the reader is that they can follow Pete’s blog which is arguably the most vibrant and provocative of blogs – Brain Hammer – here is a real enthusiast. Oh yes, a characteristic Mandik paper entitled “Shit Happens” for EPISTEME‘s special issue on conspiracy theories is well worth checking out given that conspiracy continues to animate the popular mind.

Amy Gutmann cites Oakeshott

Oakeshott cited by Penn State President in convocation address. (Quote from “The Idea of A University,” p. 103, Voice of Liberal Learning, Yale 1989.)

Succumbing to the temptation of easy answers would be fatal to your intellectual growth. You did not come to Penn to regress into what Michael Oakeshott called “the clamorous and conflicting absolutes of adolescence.” Rather, you came here as intellectual adventurers who, by wrestling with complexity, will raise the caliber of discourse in our society.

Julius Moravcsik

Leiter reports on the passing of Julius Moravcsik. I recall Moravcsik’s work on Aristotle’s metaphysics as being a model of clarity and being informed by recent philosophy of mind. A top-draw philosopher who published because he had something to say; not because he liked the “sound of his own voice”. Click here for a bio-sketch.

Alan Turing

450px-Alan_Turing_Memorial_Closer

The BBC has been running a series of articles on Turing.

For those of us who often discuss the conceptual aspects of liberty through the great works of social and political philosophy, we should stop and think about how our liberty was, to a great extent, preserved by Alan Turing.

According to Winston Churchill, Turing made the single biggest contribution to Allied victory in the war against Nazi Germany.

His pivotal role in cracking intercepted messages helped the Allies to defeat the Nazis in several crucial battles.

A Profile and the Turing us philosophers/cognitive scientists know through his “Computing machinery and intelligence”, Mind 50: 433-460.

I PROPOSE to consider the question, ‘Can machines think? ‘This should begin with definitions of the meaning of the terms’ machine’ and’ think’. The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous. If the meaning of the words ‘machine’ and  ’think ‘ are to be found by examining how they are commonly used it is difficult to escape the conclusion that the meaning and the answer to the question, ‘Can machines think?’ is to be sought in a statistical survey such as a Gallup poll. But this is absurd. Instead of attempting such a definition I shall replace the question by another, which is closely related to it and is expressed in relatively unambiguous words.

Lies

The most dangerous untruths are truths moderately distorted.  ~Georg Christoph Lichtenberg

Anthony Grayling’s article Don’t dismiss dishonesty, it can be virtuous takes wing from two law lecturer’s research (no citation given), who according to Grayling, say “that they have found that there is no consensus in our society about what honesty is.”  Grayling’s thesis, as interesting as it is, is that “across time and culture, our notion of honesty shifts. What doesn’t is the way every generation gets lost in the grey areas” – still doesn’t cut very deep. A deeper and more subtle analysis of dishonesty is to be found in David Livingstone Smith’s Why we lie: The evolutionary roots of deception and the unconscious mind which is reviewed by law professor Tamar Frankel. A listing of interviews (some with links) by David on this topic can be found here.

The Lives of Ants

I came across a “review” of The Lives of Ants by Keller and Gordon. The book seems to have been very well received across several publications. Here is the Economist‘s “review” kindly sent to me by Shannon Selin.

This pheromone-driven behaviour means that although single ants are not clever, collectively they are capable of complex tasks. Such “swarm intelligence” is of huge interest to scientists and has already led to practical applications. Unilever, for instance, has used a computer program based on swarm intelligence to organise movements between storage tanks, mixers and packing lines in one of its factories.

Though Keller and Gordon (nor the reviewer) do not seem to invoke the term stigmergy, they do of course discuss swarm intelligence. This work follows in the wake of Sunstein’s Infotopia: How Many Minds Produce Knowledge and Surowiecki’s The Wisdom of Crowds: Why the Many Are Smarter Than the Few and How Collective Wisdom Shapes Business, Economies, Societies and Nations, neither of which are particularly deep. Still, it’s nice to see ideas such as these enter the popular domain.
