Kenneth Aizawa, "Compositional Abduction and Scientific Interpretation: A Granular Approach" (Cambridge UP, 2025)
Episode 379
Saturday, 10 January, 2026
How do scientists reason when they posit unobservables to explain their observed results? For example, how did Watson and Crick reason that DNA had a double-helix structure when they observed Franklin’s image 51, or how did Hodgkin and Huxley reason that sodium ions carried the current flowing into the membrane of a voltage-clamped giant squid axon? In Compositional Abduction and Scientific Interpretation: A granular approach (Cambridge University Press), Kenneth Aizawa argues for an account of such reasoning as singular compositional abduction: explaining particular experimental results in terms of lower-level entities, such as the bonds between nucleotides or the positive charges of sodium ions. Aizawa, who is professor of philosophy at Rutgers University—Newark, draws on close examination of scientific practice to argue that dominant views in philosophy of science regarding abduction do not capture what scientists are actually doing. Instead, he articulates compositional abduction as a specific form of inferential practice in science distinct from eliminating alternative hypotheses, employing hypothetical-deductive confirmation, or identifying mechanism components.
