Metaphysics of Quantities

Quantities are ubiquitous in science and especially in the physical sciences. My project aims to provide a comprehensive metaphysical account of quantities. A metaphysical account of quantities must address three key questions:

  1. What distinguishes quantities from other attributes like qualities and kinds?
  2. What ontology is needed for quantities?
  3. What is the relationship between quantities, theory, and measurement?

In this project I develop and defend a systematic answer to all three questions. The resulting view of quantities is (cautiously) realist in the sense of scientific realism, structuralist, substantivalist, and non-reductionist.

    Dear Jo
    The topic of kinds and quantities is of great interest. Can you provide me with a password?

      Dear Gunnar,

      Thank you for your interest! The files up here are actually no longer up to date. The good news is that the book is now out with Oxford University Press, so your library might have it or be able to order it for you.

      All best,
