I think there are some very good reasons not to be realists about mathematical objects. What might our metaphysics of mathematics need to look like to defend nominalism?

I explain Van Inwagen's 'SCQ' and examine some potential resolutions, including mereological nihilism, mereological universalism, organicism and more.

What is Theseus' Paradox? I examine some potential solutions, and consider what our answers tell us about the metaphysics of identity and of identity change.

Duchamp's Fountain challenged the way we think about art. I review some of the philosophical implications of the Fountain and celebrate his art's long-standing philosophical legacy.

What is an object? When do objects compose further objects? I explore the metaphysical issues in this philosophical introduction to objecthood and the nature of reality.

I propose a system of meaning for existence monists, and argue that the monist can claim exceptional parsimony as a motivation for their ontology.

Existence monism is the view that there is exactly one object – the cosmos. It's often met with an incredulous stare. I defend the view in this post.
