Abstract

This paper assesses Sarkar's ([2003]) deflationary account of genetic information. On Sarkar's account, genes carry information about proteins because protein synthesis exemplifies what Sarkar calls a ‘formal information system’. Furthermore, genes are informationally privileged over non-genetic factors of development because only genes enter into arbitrary relations to their products (in virtue of the alleged arbitrariness of the genetic code). I argue that the deflationary theory does not capture four essential features of the ordinary concept of genetic information: intentionality, exclusiveness, asymmetry, and causal relevance. It is therefore further removed from what is customarily meant by genetic information than Sarkar admits. Moreover, I argue that it is questionable whether the account succeeds in demonstrating that information is theoretically useful in molecular genetics.
