Causation & Time Reversal

Matt Farr (Queensland) gives a talk at the MCMP Colloquium (20 January, 2016) titled "Causation & Time Reversal". Abstract: What would it be for a process to happen ‘backwards’ in time? Would such a process involve different causal relations? On a standard interpretation of time reversal, time reversal symmetric theories radically underdetermine causal relations between events. This has led many to imply that time reversal symmetry motivates eliminativism about causation. This paper assesses the compatibility of time reversal symmetry with causation by asking whether causal relations ought to invert under the action of time reversal or remain invariant. I show that in neither case is there an incompatibility between time reversal symmetry and causation and hence time reversal symmetric theories pose no special problem for causality. I argue for a ‘non-causal’ interpretation of time reversal, whereby time reversal does not invert causal relations, and assess the consequences of this interpretation for the epistemology and metaphysics of causation.
