You can ignore the part about German phenomenology if you like, sorry (it spawned The Social Construction of Reality that I wrote a post on long ago, and Conversation Analysis (we don't have a theory! All there is is subjectivity! We cannot know more than is publicly available! We analyze minute details of conversation structure because face-to-face conversation is the genesis of society and all social norms can be explained through it! Without conversational norms people would kill each other! They would hate! They would be selfish and cruel!). My point is that any theory that tries to explain human thought/behavior purely through rational processes is ignoring a large part of how those "constraints" work. Yes, they do shape how you view what is rational, but sometimes they shape pure reaction, gut-feelings, impulses, aesthetics, desires, many non-rational parts of our being. Things that are learned don't have to be rationally held assumptions. They can be part of our ways of perceiving and un-reflectively responding to the world. I think it's limiting to lump all of that into constraints. I don't think every action is a (rational) decision.

What's "expressive" rationality?
