Aristotle’s philosophy of nature dominated much of the world’s science from late antiquity until the 17th century and beyond. In this Aristotelian world, human beings and the middle-sized objects that we perceive and manipulate were among the first-class citizens of nature, imbued with real causal powers and potentialities. The period of “classical” physics (from Galileo to Rutherford) seemed to eliminate the need for key elements of Aristotle’s scheme, including substantial forms for composite objects, natural powers and potentialities, and teleology. I argue that the Quantum Revolution has altered the epistemic landscape in ways that re-open questions of natural philosophy that have long been taken to be settled, laying the foundation for a neo-Aristotelian or “hylomorphic” interpretation of quantum theory. This interpretation successfully bridges the gap between the domain of quantum entities and the world of actual experiments and observations, and, as a further bonus, reconciles what Wilfred Sellars called the manifest image of ordinary human life with our best scientific image of nature.
Followed by a Question and Answer Session introduced and moderated by Jonathan Price. Part of the colloquium 'Why Middle Sized Matters to Science, Theology, and Metaphysics, held in cooperation with the University of Texas at Austin.
