Abstraction: Philosophy and Mathematics 
Summer school and workshop
University of Oslo, 22 - 24 May 2014

Organized by Salvatore Florio and Øystein Linnebo


THEME

According to Frege, the notion of abstraction has a central role to play in a philosophical account of classical mathematics. For instance, Frege regarded the direction of a line as somehow "abstracted from" the line in question, governed by the principle that the direction of one line is identical with the direction of another just in case the former line is 
parallel with the latter. Principles of this form are known as abstraction principles and play a central role in the neo-Fregean abstractionist programme initiated by Bob Hale and Crispin Wright. 
   This combined summer school and workshop aims to take stock of the abstractionist programme after three decades of intensive philosophical and technical study, as well as to make progress on some questions that have recently received much attention, such as the metaontology of abstraction and the variety of responses to the bad company problem, including the possibility of a more "dynamic" approach to abstraction (recently advocated by Øystein Linnebo, James Studd, and others), which sees abstraction as a process whereby ever greater domains of abstracta are "generated".
