Raymond Guess, a philosopher affiliated with the University of Cambridge, recently wrote about the evolution of the Frankfurt School of social philosophers. Guess observes that Adorno, in 1951, questioned the "liberal fiction which holds that any and every thought must be universally communicable to anyone whatsoever." We shouldn't make a fetish of communication or communicability, making it too fundamental an organizing principle. Guess adds that the Frankfurt school soon fell into the trap Adorno had warned about. Jurgen Habermas, in the early 1970s, introduced what Guess calls a "normatively highly charged concept of 'discourse'" and "communicative action" that does exactly this -- in the hope of reinvigorating a Kantian liberalism. What d I think about all this? I will let you ... Guess.
