Origins in Critical theory
The concept doesn't start as late as with Habermas. It originates with Max Weber's The Protestant Ethic and the Spirit of Capitalism, and was specifically adapted for Critical Theory by Theodor W. Adorno in the 1947 Dialectic of Enlightenment. --22.214.171.124 (talk) 18:21, 17 August 2011 (UTC)
Should not be a 'dual article'
If I read correctly, the second section is about rationality concerning measuring instruments in science. It's find to have a mention and a link, but there's apparently already another article called instrumentation that covers it. "Instrumental rationality" viewed from philosophy, sociology, anthropology, etc., is already the substantial focus of the article and should be the formal focus as well. I hope to expand the substance also. Pax, groupuscule (talk) 09:33, 23 August 2012 (UTC)
