However, to date, there has been little attempt to use computer models in the development and evaluation of metaphysical theories. This is a shame, as there are good reasons for believing that metaphysics could benefit just as 1 Earlier versions of this paper were presented at the Forum on Philosophical Methods at Sun Yat-Sen University, Zhuhai as well as the 8th Asia-Pacific Conference on Philosophy of Science at Fudan University, Shanghai. I thank the participants for their helpful comments. I am also grateful to two anonymous reviewers from Manuscrito who also provided invaluable feedback on an earlier version of this paper.

In this paper I assess the possibilities and limitations of using computer models in metaphysics. I outline the way in which different kinds of model could be useful for different areas of metaphysics, and I illustrate in more detail how agent-based models specifically could be used to model two well-known theories of laws: David Lewis’s "Best System Account" and David Armstrong's "Nomic Necessitation" view.
