Alexander Paseau

Alexander Christopher Paseau is a British philosopher of Greek and Belgian origin. He is professor of mathematical philosophy at the University of Oxford and the Stuart Hampshire Fellow at Wadham College. He specialises in the philosophy of logic, the philosophy of mathematics, metaphysics, epistemology, and the philosophy of religion.

As of January 2025, he is editor-in-chief of The Journal for the Philosophy of Mathematics . He has been an Associate Editor of the journal Mind and has held Research Fellowships from the Mind Association and the Leverhulme Trust.

Research work Paseau subscribes to a broadly realist conception of mathematical truth, stating in an interview that "mathematical truth is not tensed. Mathematicians discover mathematical truths; they don’t make them up". In the same interview, Paseau also maintains that "inductive reasoning is crucial for mathematical knowledge" and that "we can know a mathematical truth without ever having proved it".

In their book One True Logic, Paseau and his co-author Griffiths argue that there is one correct foundational logic and that it is highly infinitary.

Paseau also works on the subtraction argument for metaphysical nihilism. Paseau's view is discussed and defended by Gonzalo Rodriguez-Pereyra in "The Subtraction Arguments for Metaphysical Nihilism: Compared and Defended".
