This is by far the hardest book I've ever finished. Habermas is supremely knowledgeable and is not the most clear of writers, but this book and the second volume are a tour de force. I particularly liked how Habermas relies on an action-based framework to base his whole philosophic construct on. Leveraging, Rawls and other analytical philosophers to update his Marxian-influenced theories was refreshing (not to mention Luhmann's system theory). Overall, I certainly felt very convinced at the end but would struggle to clearly articulate what Habermas theory is
The ‘Calorie Man' absolutely blew my mind (and made me realize energy abundance is not a normal state of affairs — in a very opportune moment, as growing power demand coming from data centers / AI makes us face the hard constraint of energy). All the stories are very grim though
