 Several authors have argued that the causal asymmetry and the direction of causation are closely related to the thermodynamic asymmetry that the entropy of a closed system does not decrease. An early discussion of possible connection between the two “temporal arrows” occurs in Reichenbach (1956). More recent discussions of connections between the two arrows argue more perspicuously that the thermodynamic and the time-asymmetry of causation have as their common origin the initial randomness assumption or the assumption of initial microscopic chaos. The assumption of initial microscopic chaos is a central assumption in neo-Boltzmannian accounts of the thermodynamic asymmetry. These accounts posit a cosmological hypothesis, according to which the universe began its life in an extremely low entropy state \(M(0),\) which Richard Feynman has dubbed the Past Hypothesis (1965), together with an equiprobability distribution over all microstates compatible with \(M(0).\) David Albert and Barry Loewer argue that the package consisting of past hypothesis, probability postulate, and the dynamical laws on the microlevel—a package they call the Mentaculus after the Coen Brother’s movie A Serious Man—not only can account for the thermodynamic asymmetry but also provides the probabilities for every macroscopic generalization as well as the machinery to ground the causal asymmetry and epistemic asymmetries concerning our access to past and future events (Albert 2000, 2015; Loewer 2007, 2012).
