If you want to learn about different philosophies, Jason Waller’s page might be a good place to start. Waller is interested in Early Modern Philosophy (esp., Seventeenth Century Rationalism) and Metaphysics (esp., Persistence, Time, Space, Special Relativity, and Material Constitution.) He also has an interest in the study of how bodies persist through time in Spinoza’s metaphysics.
Some of the papers Waller wrote include: Spinoza’s Attributes and the ‘Intermediate’ Distinctions of Henry of Ghent and Duns Scotus; Numerical Sameness Without Identity of Property Tokens; Defending a Pure Biological Interpretation of a ‘Form of Life’ as used in the Philosophical Investigations and more.
Jason Waller was a PhD student of Purdue University, Department of Philosophy.
