Concepts of Colour and Limits of Understanding
This chapter examines some puzzling reflections by Ludwig Wittgenstein on the possibility of understanding concepts of the colours of things different from those already familiar to us. It begins with a discussion of Wittgenstein’s statement: ‘Someone who has perfect pitch can learn a language-game that I cannot learn’. In particular, it considers how Wittgenstein draws a connection between perfect pitch and concepts of colours and invites us to imagine people who speak of colours intermediate between red and yellow by means of fractions in a kind of binary notation representing different proportions of the colours at each end of the range from red to yellow. The chapter also analyses Wittgenstein’s views on whether the number system and the colour system ‘reside in our nature or in the nature of things’.
