### Wittgenstein on Counting in Political Economy

#### Abstract

Philosophers are … interested in matters of normativity: What is it for person

A to be obligated to do action B? What do we mean when we say that one ought to do

something, like give to a charity? Mathematics and mathe¬matical logic provide at

least one important and, possibly simple, case. Logic is normative if anything is.

In what sense are we required to follow the canons of correct reasoning when doing

mathematics? (Stewart Shapiro, Thinking About

Mathematics (Oxford University Press, 2000), 5.)
