Neo-Fregeanism Workshop

Abstractionism/Neo-Fregeanism in the philosophy of mathematics is the thesis that Fregean abstraction principles, such as Hume's Principle, play an essential role in our knowledge of mathematical truths, the existence of mathematical objects, and our capacity to effect singular reference to these objects. The workshop will explore the logico-mathematical aspects of neo-Fregeanism, such as Frege's Theorem and the Bad Company Objection, as well as its philosophical aspects including Frege's Caesar Problem, the possibility of mathematical singular thought and/or reference, and the epistemology of abstraction principles. The workshop occasions the imminent publication of the second edition of Crispin Wright's Frege's Conception of Numbers as Objects. We will explore variations on themes from Wright.
