Postponed: Matt Farr, “Do we need to explain initial conditions?”

Our next visitor in the FraMEPhys Seminar series was to be Dr Matt Farr (Cambridge). Unfortunately Matt’s talk has had to be postponed to a later date, TBC. Matt’s title and abstract will be as follows: 

Do we need to explain initial conditions?
It is common to think of the universe as a grand time-directed process that started out in some initial state — call this the ‘time-directed universe’ hypothesis (TDU). On TDU, the initial state is explanatorily unique — it is the only one that did not evolve from some prior set of conditions. Some have appealed to this explanatory uniqueness to suggest that it is misguided to seek an explanation as to why the early universe was extremely low-entropy, and so argue that TDU plays an important explanatory role in physics. But what if we reject TDU? This talk considers the options for those that assume a temporally adirectional metaphysics, which I call the ‘C theory’. Given the C theory holds there is no intrinsic difference between ‘initial’ and ‘final’ states of physical systems, it is unclear what we are to make of the explanatory demands of the low entropy early universe. I assess a series of options for the C theory, arguing that the rejection of TDU leaves us no worse off with regard to explaining the low entropy early universe.

Before the talk, there will be a reading group with the speaker. The paper we’ll discuss is “Measures, Explanations and the Past: Should ‘Special’ Initial Conditions be Explained?” by Craig Callender, available here: https://doi.org/10.1093/bjps/55.2.195
