I have just finished writing my presentation for the conference on Agency and Quantum Physics in Innsbruck. I’m excited about it. This is the first time that I’m invited to give an hour long talk at the major session of an international conference. The conference begins on March 30th and ends on April 2nd. Here is the abstract of my paper:
Metaphysics of Downward Causation:
Nonreductionist Physicalism versus New Aristotelianism
Mariusz Tabaczek, O.P.
Graduate Theological Union, Berkeley, CA
Many proponents of methodological nonreductionism in contemporary science find the notion of downward causation (DC) a sine qua non of the strong (ontological) version of emergence (EM), which strives to give an account of the irreducible character of the complex levels of the organization of matter. But what for many is the essence of nonreductionist physicalism, carries with it quite a bevy of problematic issues, and becomes a stumbling block and an obstacle for those, who acknowledge the metaphysical and logical inconsistencies of the emergent theory based on the idea of DC. For how can physicalism be non-reductionist? How can DC be reconciled with the causal closure of physics? What do “higher” and “lower” levels refer to? What is causal in DC? What is being caused (acted upon)? What is the very nature of DC?
I will argue that the defense of DC requires from us a broader notion of causation, which goes beyond the efficient causes accepted and described in modern science. I want to argue in favor of the retrieval of formal causation in particular. Its acceptance not only makes EM and DC plausible, but also helps to overcome and replace Humean causation of events with the causation of living and non-living beings, explained in terms of their causal powers and dispositions. I hope to show, in the course of my presentation, that true non-reductionism needs to be philosophically grounded. Yet it can still remain compatible with science provided it values and is open to the reflection offered by philosophy of nature. My position follows new Aristotelianism developed within the analytic tradition, although an explicit reintroduction of formal cause goes beyond it to the original thought of Aristotle.
