I read his book Zebras and Ulcers and found it a little bit shallow. It goes into the endocrinology of chronic stress and he talks a lot about social status as it relates to baboon troops, which is his main area of research. I guess it's a five stars kind of book if you're an endocrinologist interested in baboons. I felt he tries to draw too many analogies to the general human condition from his relatively narrow expertise. He's not a generalist able to synthesize lessons of the human experience informed from art and classical literature like Peat.
I mean, Sapolsky goes on at length about work stress being about a boss beating up on a subordinate, as you might see in a business of monkeys. Anyone with real world white collar work experience knows that's not an especially useful narrative about why a job is stressful. We're just not monkeys or baboons. (Potentially touchy side note: I've noticed many intellectual jews are rather overly interested in social status/hierarchy as a general topic. Consider Marx as an example, or any number of New York Times columnists as minor examples. Sapolsky's research is obsessed with mammalian social hierarchy as it relates to stress, as if that were the critical aspect of human "stress".)
Anyway, I'm rather tipsy and spitballing but the point I want to make is that you want to draw lessons about how to live life from well educated generalists like Ray Peat, rather than specialists like Sapolsky.
Even with Peat I feel you need to understand his biases and take him with a huge grain of salt at times. If you read his work from the 60s and 70s he was rather clearly a communist sympathizer. You have to read that from between the lines but it's not exactly ambiguous. I've been thinking about writing up a post on this important point. I suspect the reason a lot of his prose is unnecessarily dense at times is a learned habit because he came of age in an era when communist sympathies were dangerous. I'm quite sure Ray Peat has a substantial FBI file. It might be available by now via FOIA. Related to his probable communism he has powerful prejudice against Western Christian philosophy, both Catholic and Protestant. His hand wavy dismissals of the underlying philosophies of western civilization can come across laughable, when he brings it up.
