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.

I grew up in a few places — north London, southern Maine, and the New York area. Maybe this transnational childhood is why I’m so bewitched by philosophers who think of themselves as belonging to multiple worlds. I have been concentrating on Benedict de Spinoza, a migrant philosopher.

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


We can better appreciate the strength of Spinoza’s masterpiece, the Ethics, once we see that he is trying to portray how the world looks to someone who is undergoing a spiritual transformation. That’s what I argue in a book in progress, tentatively entitled Meaning Meandering: Semantic Flux in Spinoza's ‘Ethics’.

My essay “Spinoza on Time” is forthcoming in the Blackwell Companion to Spinoza.



At the University of Pennsylvania, I am presently team-teaching a course on the history and economics of poverty. This course is part of Penn’s innovative Integrated Studies Program, which teaches interdisciplinary thinking. As a teaching fellow in the program, I’ve team-taught courses that blend philosophy of education with cognitive neuroscience and ancient Greek thought with European intellectual history.

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

In the spring of 2013, I co-taught a course in modern political thought at a youth correctional facility.
