Abstract

Most of current theoretical analyses on biological functions can be classified as etiological or dispositional, depending on how they deal with the teleological dimension. In this paper, we propose a critical survey of these two perspectives, and we argue that some recent studies have set the basis of a new approach which grounds the teleological dimension of functional attributions in the organizational properties of living systems. We outline a new proposal within this new approach, based on an interpretation of living systems as organized self-maintaining systems.
