I had on my to-do list "Rickert Notes" b/c I have been reading Acts of Enjoyment, but being the social media scholar that I am (cough cough), I thought I should see what notes others have written first. Saves a lot of typing.
Jim Brown has an extended entry comparing Rickert and Rice.
Everything else I found gave Rickert a mention, but no notes to steal / borrow. Too bad. Lots of "go read it" recommendations, but no notes.
I'll post my notes here if I ever get 'em finished.
