@8a2094ca Great point! By absolutely sheer coincidence (and definitely not because I'm any type of well read fancy pants), I was just diving into another old book whose last chapter you might be interested in: The wisdom of the body. Walter Cannon, 1932 (This book was the first to coin the term "homeostasis" and introduce fight-or-flight). Available via the internet archive. https://neuromatch.social/system/media_attachments/files/111/024/397/564/858/447/original/417b455f5e2534fb.png
