Abstracts:

John Cusbert: “Causal loops and unstable chances” 
Intuitively, objective chances are stable: if you repeat an experimental trial, then the chances of its various possible outcomes should stay the same. However, some time travel cases threaten instability, since duplicate setups can apparently yield different chances, if one of them is embedded in a causal loop. I’ll consider the nature and extent of this instability, and suggest a stability thesis that handles such cases.

Nikk Effingham: “Heterodox Ludovicianism” 
This paper criticises Lewis’s contextualist solution to the Grandfather Paradox on the grounds that Lewis does not take seriously the modality of impossibility. I then develop a variant contextualist response to the Paradox that looks more profitable.

Graeme A Forbes: “Quantum Leap with a MOP” 
I shall be developing Bernstein’s discussion of a Moveable Objective Present (MOP), and examining the role of chancy causation in two cases: 1) causing the objective present to move, and 2) the development of time after a discontinuous movement of the objective present.
