Show Summary Details


This chapter is a detailed study of predicativity in mathematics. It presents a number of historical versions predicativity requirements (Russell, Poincaré, Weyl), looking for unifying ideas. The further development of the notions and requirements up to the present is traced, articulating connections among the different ideas. One underlying theme of the chapter is the motivations for the various requirements for rejecting impredicativity and the various ways of stating the requirement.

Keywords: predicativity; mathematics; Russell; Poincaré; Weyl; impredicativity
