Abstract

Teleology features prominently in recent discussions in the philosophy of mind, action theory, philosophy of biology, and in the dispute between Intelligent Design theorists and Darwinian naturalists. Unfortunately, discussants often talk past each other and oversimplify the issues, failing to recognize the differences between the several theories of teleology philosophers have historically put forward, and the different natural phenomena that might be claimed to be teleological. This paper identifies five possible theories of teleology, and five distinct levels of nature at which teleology might be said to exist. Special attention is paid to the differences between Aristotelian-Thomistic and ID theoretic approaches to teleology.
