In A Third Window Robert Ulanowicz exposes the explanatory weaknesses of both classical and statistical methods in scientific inquiry. His book, however, does much more than that. While being completely grounded in empirical science, it also outlines a worldview, or a metaphysics, that renders intelligible the fact of chance and emergent novelty. Ulanowicz establishes his position by comparing his third window onto nature with two others conventional scientific approaches. The purpose of this essay is to point out the value of (...) Ulanowicz’s approach for improving the quality of conversation between science and theology. (shrink)

The starting point for this article is the question of the relationship between Darwinism and Christian theology. I suggest that evolutionary theory presents three broad issues of relevance to theology: the phenomena ofcontinuity, naturalism, andcontingency. In order to formulate a theological response to these issues I draw on the semiotics (theory of signs) and cosmology of the American philosopher Charles Sanders Peirce. Peirce developed a triadic theory of signs, underpinned by a threefold system of metaphysical categories. I propose a semiotic (...) model of the Trinity based on Peirce's semiotics and categories. According to this model the sign‐processes (such as the genetic “code”) that are fundamental to life may be understood as vestiges of the Trinity in creation. I use the semiotic model to develop a theology of nature that addresses the issues raised by evolutionary theory. The semiotic model amounts to a proposal for a new metaphysical framework within which to understand the relationship between God and creation and between theology and science. (shrink)

The respondent agrees with William Grassie that many windows on nature are possible; that emphasis must remain on the generation of order; that “chance” would better be recast as “contingency”; and that the ecological metaphysic has wide implications for a “politics of nature”. He accepts the challenge by Pedro Sotolongo to extend his metaphysic into the realm of pan-semiotics and agrees that an ecological perspective offers the best hope for solving the world’s inequities. He replies to Stanley Salthe that he (...) now agrees that the second law of thermodynamics is the overarching law of nature, but only when the duality inherent in of the concept of entropy is widely recognized. The respondent is enthusiastic over Jeffrey Lockwood’s extrapolation of process ecology to include the concept of “species” and over John Haught’s description of how the construct paves the way for a “theology of evolution” by recasting evolution as an unfolding “drama”.

This paper is an extended discussion of Robert Ulanowicz’s critique of mechanistic and reductionistic metaphysics of science. He proposes “process ecology” as an alternative. In this paper I discuss four sets of question coming out of Ulanowicz’s proposal. First, I argue that universality remains one of the hallmarks of the scientific enterprise even with his new process metaphysics. I then discuss the Second Law of Thermodynamics in the interpretation of the history of the universe. I question Ulanowicz’s use of the (...) terms “random” and “chance” in his definition of process. Finally, I discuss what difference a relational and process metaphysics might make in addressing the political and practical problems in the twenty-first century. (shrink)
