Abstract

In his The Road to Reality as well as in his Fashion, Faith and Fantasy, Roger Penrose criticizes string theory and its practitioners from a variety of angles ranging from conceptual, technical, and methodological objections to sociological observations about the string theoretic scientific community. In this article, we assess Penrose’s conceptual/technical objections to string theory, focusing in particular upon those which invoke the notion of ‘functional freedom’. In general, we do not find these arguments to be successful.
