In a new paper from the project, Retrocausality At No Extra Cost, philosophy postdoc Peter W. Evans constructs a picture of what the world would need to be like to permit backwards-in-time causal influences. By considering the nature of time and causation, our intuitions concerning the very small and what we can know about the past and the future, Evans argues that our world is just such a world. Evans' paper is published in the philosophy of science journal Synthese, and also available to read at the PhilSci Archive.
