Brentanians against Relationalism about Colours

Abstract

Abstract The aim of my article is to present the critique by Brentanians – more precisely, by Brentano himself and his students Stumpf and Marty – of the thesis that colours are properties that are relational to a perceiver. For Brentanians, colours are monadic physical properties. Brentanians, I will show, think that colours do not exhibit a relationality to perception when we experience them, and that the concepts of them do not contain any mark representing a relation to perception; this phenomenological and logical non-relationality, they think, allows them to hold that colours are not relational by nature. Despite arguing that colours are monadic and physical, Brentanians also hold that colours do not exist in reality, and in their opinion these two theses are perfectly compatible. I will further show that although Brentanians (especially Marty) claim that colours are monadic, they nonetheless allow for a loose relationality of colours to perception which is, however, identical to that of any other physical property. I will conclude by discussing some interesting consequences of the Brentanian theory for contemporary debates about colours.
