Hi, there! My name is Raphael Krut-Landau. I live in beautiful Philadelphia, where I teach at the University of Pennsylvania. I also write about European philosophy's early modern period, roughly 1600 to 1800. Specifically, I write about Spinoza's metaphysics and psychology, which I've been trying to connect with various streams of ancient and medieval thought – physics, mathematics, medicine, and literary criticism.

I grew up in a few places: north London, southern Maine, and the New York area. Maybe this transnational childhood explains why I’m now so fascinated by philosophers who think of themselves as belonging to multiple worlds.

You can reach me at rkrut@sas.upenn.edu and find me at academia.edu. Here’s my CV.


My research focuses on metaphysics and philosophy of language in the writings of Benedict de Spinoza.

My article “Spinoza's Metaphysics of Time” is forthcoming in A Companion to Spinoza (ed. Yitzhak Melamed, Blackwell, 2021).


I teach interdisciplinary courses at the University of Pennsylvania, in the Integrated Studies Program. The premise of this program that students can become bolder and more creative by hunting for unexpected connections between multiple fields of inquiry.

As a postdoctoral teaching fellow in the program, I’ve team-taught courses that blended philosophical and neuroscientific perspectives on education and curiosity, as well as ancient and modern perspectives on rebellion, poverty, and evolution.

I’ve taught several other courses at the University of Pennsylvania since 2015: Introduction to Modern Philosophy (three times), Topics in Ethics: Ethics and Language, Topics in Ethics: Love and Sex, Philosophy of Science, and Philosophy of Social Science.

In the spring of 2013, I co-taught a course in literature and political thought at a prison in New Jersey.
