Her art graces the covers of philosophy books such as The Philosophy of Spirituality (Brill 2018) and Introduction to Philosophy of Mind (Rebus 2019).

We would also like to acknowledge the many philosophy students, faculty and researchers who have contributed to the project by providing comments along the way, such as discussions on the Rebus Community platform when we were originally envisioning the series and what topics should be included, as well as giving feedback on drafts of chapter outlines for books. There have been many very helpful contributions from too many people to list here, and the books would not have come together without them.
