The Facts in Logical Space: A Tractarian Ontology

Philosophers have long been tempted by the idea that objects and properties are abstractions from the facts. But how is this abstraction supposed to go? If the objects and properties aren’t ’already’ there, how do the facts give rise to them? Jason Turner develops and defends a novel answer to this question: The facts are arranged in a quasi-geometric ’logical space’, and objects and properties arise from different quasi-geometric structures in this space.

Jason Turner, University of Arizona

Jason Turner received his PhD from Rutgers in 2008 before going on to work at the University of Leeds, St Louis University, and most recently the University of Arizona. He thinks mainly about metaphysics and philosophical logic but is secretly interested in everything. Much of his recent work focuses on the interaction of metaphysics with logical notions, such as existence and identity. He has also published work on modality, free will, the philosophy of religion, and the structure of mental content, and will probably continue to so dabble until someone makes him stop.
