 Presumably for these reasons, contemporary theories abandon the attempt to ground the arrows of time on thermodynamic entropy. Instead, they turn to statistical mechanics, that which grounds the thermodynamic arrow. This more general basis is regarded as more fertile ground for the other arrows. In effect, the thermodynamic arrow is just regarded as another non-basic arrow like those four mention above. Horwich (1987) traces the arrows back to initial micro-chaos. Albert (2000, 2015) and Loewer (2012) instead trace them to a package dubbed the Mentaculus (after the Coen brothers’ film, A Serious Man, 2009). Let’s briefly consider how Albert and Loewer propose to derive the thermodynamic arrow, the epistemic arrow, and the causal arrow all from the Mentaculus.
