As much as I enjoy the first (except the second chapter on "natur= al" reasoning/proof system, which I skipped as it is completely unreadable = for the moment)) I quickly hated the second as, as has been said, it's QUIT= E not the right orientation, indeed. It casts everything in nonsensical mumbo-jumbo (to be polite ;-) ) whereas = a down-to-earth - and finitist - approach would use primarily basic field a= gebra, multisets and operations on them to model logical reasoning.
