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.)
