This comparative study searches out intersections in the thought of Giambattista Vico and Michael Polanyi by situating their thought in relation to the history of ideas generally and to the rhetorical tradition specifically. The overarching concern of the essay is the relation between knowing and making truth -- or, in rhetorical terms, between wisdom and eloquence.

Polanyi’s vision of the cosmic process as undergirded by a logic of emergence common to both the mental life of human beings and the processes of non-human nature can be vindicated if one is prepared to make certain adjustments in the notion of morphogenetic fields with an active center or organizing principle. Given the author’s field-oriented interpretation of Whiteheadian societies, it should be possible to think of entelechies or final causes in developmental rather than strictly Aristotelian terms. That is, the “common element of form” or organizing principle of a Whiteheadian society depends for its own existence on the spontaneous activity of previous sets of actual occasions and yet serves as the ongoing principle of formal and final causality for the present set of actual occasions and still others to follow it. In Aristotelian language, matter and form thus dialectically condition one another and neither is ontologically superior to the other.

Bracken synthesizes Polanyi’s notion of morphogentic field and Whitehead’s notion of societies of actual occasions. These comments emphasize the implications of the metaphors involved in these notions. The rnetaphor of plants growing in afield lies beyond the concept of a morphogenetic field, and the metaphor of a society of interacting persons lies behind the concept of a society of actual occasions. I suggest that one of the implications of this metaphor is that there is not, as Bracken argues, a problem of continuity in Whitehead’s metaphysics of events.

Joseph Bracken proposes to modify Whitehead’s tendency to see the comprehensive entities of everyday life as but aggregations of actual occasions. While there are resources in Polanyi’s notion of an emergent cosmos to counter Whitehead’s atomism and reductionism, Bracken’s use of Polanyi’s theory of a morphogenetic field as a corrective is argued to be only partially successful. Bracken must explain how morphogenetic fields evolve and arise. This step would require (1) replacing Whiteheadian reductionism with a principle of ontological parity that honors the reality of interaction between entities and the integration of their operational principles within basic ontological levels and (2) setting forth principles of emergence to explain how these levels and fields arise.

Despite fundamental differences in the epistemologies presented by Oakeshott and Polanyi, there are some important areas of common concern which suggest further exploration. Focus here is on Oakeshott’s epistemological and disciplinary boundaries in his The Voice of Liberal Leaming.
