I defend my view that scientific progress is constituted by the accumulation of knowledge against a challenge from Rowbottom in favour of the semantic view that it is only truth that is relevant to progress.Keywords: Scientific progress; Knowledge; Aim of inquiry; Darrell Rowbottom.

This article provides a survey of Walker Percy's criticism of what Pope Benedict XVI calls “scientificity,” which entails a constriction of the dynamic interaction of faith and reason. The process can result in the diminishment of ethical considerations raised by science's impact on public policy. Beginning in the 1950s, Percy begins speculating about the negative influence of scientificity. The threat of a political regime using weapons of mass destruction is only one of several menacing developments. The desacrilization of human life (...) from cradle to grave leads Percy to assert that modern science's impact is often radically incoherent. In The Moviegoer, Percy finds his existential and theistic voice that would enable him to advance his critique of science. (shrink)
