Reductionist and antireductionist perspectives on dynamics

Abstract

In this paper reduction and its pragmatics are discussed in the light of the development in Computer Science of languages to describe processes. The design of higher-level description languages within Computer Science has had the aim of allowing for description of the dynamics of processes in the (physical) world on a higher level avoiding all (physical) details of these processes. The higher description levels developed have dramatically increased the complexity of applications that came within reach. The pragmatic attitude of a (scientific) practitioner in this area has become inherently anti-reductionist, but based on well-established reduction relations. The paper discusses how this perspective can be related to reduction in general, and to other domains where description of dynamics plays a main role, in particular, biological and cognitive domains.
