I’m a philosopher based at Instituto de Investigaciones Filosóficas (UNAM). My goal is to describe a philosophy of language suitable for mathematical language, in order to better understand how we acquire mathematical knowledge. In addition to studying objective conceptual contents and their logical prerequisites, I also study how the ability to grasp them entered our species and our culture. I’m also currently working on a book, with Harry Deutsch for Oxford University Press, about the great Alonzo Church. You’re welcome to email me at OMarshall @ gradcenter.cuny.edu
