In the philosophy of mathematics, specifically the philosophical 
foundations of set theory, limitation of size is a concept developed by 
Philip Jourdain and/or Georg Cantor to avoid Cantor's paradox. It 
identifies certain "inconsistent multiplicities", in Cantor's 
terminology, that cannot be sets because they are "too large". In modern 
terminology these are called proper classes.

Cantor's ideas formed the basis for set theory and also for the 
mathematical treatment of the concept of infinity. The philosophical and 
heuristic framework he developed had a lasting effect on modern 
mathematics, and is the recurrent theme of this volume. Hallett explores 
Cantor's ideas and, in particular, their ramifications for 
Zermelo-Frankel set theory.
