Title: Fundamentality and Time's Arrow
Author, co-author: Loew, Christian
Abstract: The distribution of matter in our universe is strikingly time asymmetric. Most famously, the Second Law of Thermodynamics says that entropy tends to increase toward the future but not toward the past. But what explains this time-asymmetric distribution of matter? In this paper, I explore the idea that time itself has a direction by drawing from recent work on grounding and metaphysical fundamentality. I will argue that positing such a direction of time, in addition to time-asymmetric boundary conditions (such as the so-called "past hypothesis"), enables a better explanation of the thermodynamic asymmetry than is available otherwise.
