Abstract

In this article I defend an account of Meteorology IV as providing a material-level causal account of the emergence of uniform materials with a wide range of dispositional properties not found at the level of the four elements—the emergence of material complexity. I then demonstrate that this causal account is used in the Generation of Animals and Parts of Animals as part of the explanation of the generation of the uniform parts (tissues) and of their role in providing nonuniform parts (organs) with the dispositional properties needed to fulfill their functions.
