These are excerpts of my talk at Oxford University on 9 Nov 2025. We took a tour of the college grounds, courtesy of some of the students. Steeped in history, the institution inspires awe and demands intellectual humility. We had a discission on when the University started. I thought in was in the 1600s. I was off by 500 years. To those who attended the lecture, thank you for coming. I had a great visit and am looking forward to staying in touch. To sign up as an SDP Changemaker, go to yoursdp.o
