I really appreciate you highlighting the Sanger/Dennett piece, that's exactly the type that I would miss without this fine, fine review. The table of contents description gives you nothing, I would have just glossed over it as "oh, in-depth book review."

Tactical diversity (and personality diversity) makes a lot of sense as an organizing tactic. I suppose one other interesting parallel I got from the piece is the way Sanger and Dennett hated each other and tore each other down. I admire both (and find both flawed) in almost equal measure and while it's good to give Dennett her shine I think one really salient lesson to learn is: let's not tear each other down. Working on progressive causes is hard enough in this reactionary moment, the tendency on the left (true on the right too I suppose but the left always seems more prone to fragmenting) is something to be all the more aware of in this particularly socially atomized age.

Really appreciate your 'sletter for highlighting this piece which is so much interesting food for thought.
