Abstract

Apparently, Polish logicians count differently from most people. This is because they
operate with different munerical criteria. Disagreements between them and us about
how many objects there are in a room will look not only insuperable but also
unintelligible unless the differences between their system and ours are brought into
the light. Similarly, if we are to put the debate about how many Wittgensteins there
are on a proper footing, it will be important to establish the criterion according to
which we are making our count.
