Hi TOK List,

  I was looking through some of my stuff and happened upon this old ToK System Guide. It offers an overview and then bulleted descriptions of several variations on the Tree of Knowledge theory of knowledge/map of science and reality. I thought I would share for anyone who wanted to scroll through it. It was done 20 years ago. Not much has changed, except for a few names and points of emphasis. We have a bit more precision on dating the universe (was ~15 bil at the time, rather than 13.8, although a recent schism has emerged that is giving rise to a 12.7 bil date).

 

  One interesting thing is that it shows how much my focus was on science writ large in 2000 rather than psychology. That is, my work in trying to get a good, zoomed out view of psychology-into-psychotherapy gave rise to the need to frame all of science. And that “popped” in 1997 and then I became obsessed with the vision logic of the ToK.

 

Best,
Gregg
