I’m continuing to be amazed by the depth and prescience of Polanyi’s Personal Knowledge. Here is a sequence of quotations from (really, the bulk of) chapter 8, “The Logic of Affirmation,” section 12, “The Fiduciary Programme”:

The critical movement, which seems to be nearing the end of its course today, was perhaps the most fruitful effort ever sustained by the human mind. The past four or five centuries, which have gradually destroyed or overshadowed the whole medieval cosmos, have enriched us mentally and morally [TC: morally? somewhat dubious] to an extent unrivalled by any period of similar duration. But its incandescence had fed on the combustion of the Christian heritage in the oxygen of Greek rationalism, and when this fuel was exhausted the critical framework itself burnt away. [pp. 265–66]

We must now recognize belief once more as the source of all knowledge. Tacit assent and intellectual passions, the sharing of the idiom and of a cultural heritage, affiliation to a like-minded community: such are the impulses which shape our vision of the nature of things on which we rely for our mastery of things. No intelligence, however critical or original, can operate outside such a fiduciary framework. [p. 266]

Our mind lives in action, and any attempt to specify its presuppositions produces a set of axioms which cannot tell us why we should accept them. Science exists only to the extent to which there lives a passion for its beauty, a beauty believed to be universal and eternal. Yet we know also that our own sense of this beauty is uncertain, its full appreciation being limited to a handful of adepts, and its transmission to posterity insecure. Beliefs held by so few and so precariously are not indubitable in any empirical sense. Our basic beliefs are indubitable only in the sense that we believe them to be so. Otherwise they are not even beliefs, but merely somebody’s states of mind. [p. 267]

[We] can voice our ultimate convictions only from within our convictions—from within the whole system of acceptances that are logically prior to any particular assertion of our own, prior to the holding of any piece of knowledge. If an ultimate logical level is to be attained and made explicit, this must be a declaration of my personal beliefs… An example of a logically consistent exposition of fundamental beliefs is St. Augustine’s Confessions. Its first ten books contain an account of the period before his conversion and of his struggle for the faith he was yet lacking. Yet the whole of this process is interpreted by him from the point of view which he reached after his conversion. He seems to acknowledge that you cannot expose an error by interpreting it from the premisses which lead to it, but only from premisses which are believed to be true. His maxim nisi credideritis non intelligitis [“unless ye believe, ye shall not understand”] expresses this logical requirement. It says, as I understand it, that the process of examining any topic is both an exploration of the topic, and an exegesis of our fundamental beliefs in the light of which we approach it; a dialectical combination of exploration and exegesis. Our fundamental beliefs are continuously reconsidered in the course of such a process, but only within the scope of their own basic premises. [p. 267]

[The] greatly increased critical powers of man… have endowed our mind with a capacity for self-transcendence of which we can never again divest ourselves. We have plucked from the Tree a second apple which has for ever imperilled [sic] our knowledge of Good and Evil, and we must learn to know these qualities henceforth in the blinding light of our new analytical powers. Humanity has been deprived a second time of its innocence, and driven out of another garden which was, at any rate, a Fool’s Paradise. Innocently, we had trusted that we could be relieved of all personal responsibility for our beliefs by objective criteria of validity—and our own critical powers have shattered this hope. Struck by our sudden nakedness, we may try to brazen it out by flaunting it in a profession of nihilism. But modern man’s immorality is unstable. Presently his moral passions reassert themselves in objectivist disguise and the scientistic Minotaur is born. The alternative to this, which I am seeking to establish here, is to restore to us once more the power for the deliberate holding of unproven beliefs. We should be able to profess now knowingly and openly those beliefs which could be tacitly taken for granted in the days before modern philosophic criticism reached its present incisiveness. Such powers may appear dangerous. But a dogmatic orthodoxy can be kept in check both internally and externally, while a creed inverted into a science is both blind and deceptive. [p. 268]

Recall: this work was written at the same time as Gadamer’s Truth and Method and Thomas Kuhn’s The Structure of Scientific Revolutions, and predates by over two decades MacIntyre’s trilogy that runs from After Virtue through Whose Justice? Which Rationality? to Three Rival Versions of Moral Enquiry. Those works, of course, have immense value in their own right (though I am beginning to suspect that Kuhn ought to be read as basically a special case of Polanyi). Yet it is remarkable how many of their core insights are anticipated here and elsewhere. MacIntyre’s “there is no rationality that is not of some tradition”? Here it is. Gadamer’s “the Enlightenment instilled an unjustified prejudice against prejudices”? Bingo. Kuhn’s recognition of regnant scientific “paradigms” that depend largely on the standards of scientific satisfaction in a given period, rather than the totality of available evidence? Ding, ding, ding. It’s all in here, folks, at least in highly compressed form.

Of course, Polanyi’s prose — which I am finding far slower even than MacIntyre’s — is a real hindrance to his reception. (The above quotations, some of which are remarkably snappy, are not exactly representative!) But in my own fields of theology and biblical studies, I cannot help thinking that discussions of method and comparison of different works which do not attend to these core insights amount only to so many exercises in wheel-spinning. Such exercises, at best, may result in a good workout — but at the end you are still sitting in the same place you were, with a great deal of sweat and exhaustion but no forward progress to show for it. Is forward progress then possible? That is the burden of the final chapters of Personal Knowledge.
