Pure mathematicians and logicians discover truths which are not justified by inference from observations; philosophers traditionally have aspired to do likewise.

This project aims to discover more about the logical roots of a priori knowledge. Pure mathematicians and logicians discover truths which are not justified by inference from observations; philosophers traditionally have aspired to do likewise. Yet little is understood about what makes a priori knowledge possible. There is a growing branch of logic which studies what is known as "double indexing" and this promises to throw light on the a priori. Australian philosophers have played a very salient role in the study of double indexing, and this project is well placed to make significant contributions in this area.Read moreRead less
Options For Proofs: New Perspectives on Propositional Logic. Philosophers and logicians recognise that proof is important, but they do not agree on what proofs are. Recent research in logic has greatly expanded our notion of proof, but this research is not unified. We need a coherent, general and applicable concept of proof. This project will unify the literature on proof and bring these insights to bear in the philosophy of language. It will show how proof can help analyse many features of ....Options For Proofs: New Perspectives on Propositional Logic. Philosophers and logicians recognise that proof is important, but they do not agree on what proofs are. Recent research in logic has greatly expanded our notion of proof, but this research is not unified. We need a coherent, general and applicable concept of proof. This project will unify the literature on proof and bring these insights to bear in the philosophy of language. It will show how proof can help analyse many features of language (more than just logical constants) but that the role of inference does not justify one kind of proof in preference to others.Read moreRead less
