Five non-fiction book recommendations from a PhD student 

I’ve bought Wonderful life on the basis of your recommendation. Looking forward to it! Thanks for the videos, helpful to see some of what a PhD can involve

I love your energy

Steven Pinker's work has received a lot of criticism from social scientists e.g. public heath, demography, economics, etc. (Pinker is himself trained as a linguist of course).

Have you read "Gaia" by James Lovelock? Personally, it really changed my perspective on the Earth and life.
