Time Symmetry in Three Dimensions.
[Preprint]
Abstract
The notion of time reversal has caused some recent controversy in philosophy of physics. In this paper, I claim that the notion is more complex than usually thought. In particular, I contend that any account of time reversal presupposes, explicitly or implicitly, an answer to the following questions: (a) What is time-reversal symmetry predicated of? (b) What sorts of transformations should time reversal perform, and upon what? (c) What role does time-reversal symmetry play in physical theories? Each dimension, I argue, not only admits divergent answers, but also opens a dimension of analysis that feeds the complexity of time reversal: modal, metaphysical, and heuristic, respectively. The comprehension of this multi-dimensionality, I conclude, shows how philosophically rich the notion of time reversal is in philosophy of physics
