There is a plethora of writings of substance in the continental tradition. Writings that we should not ignore. 'Discipline and Punish' is one of them. I recommend 'The Dialectic of Enlightenment' by Adorno as your complement to Popper's writings.
On another note, I don't generally see the value in antagonisms between paradigms or presentation forms. I find value from the analytical perspective and from critical theory, and being able to dance both dances is illuminating. I don't think the empirical process can reveal the entirety of the human experience. Steadfastly stumping for one paradigm over the other is no more useful than being a vim/emacs zealot.
If Deleuze or Foucault don't grok for you, it doesn't mean the authors are _wrong_ or lying to readers to obtain mystic status. Just like someone not caring to study Zermelo-Fraenkel set theory shouldn't write off the entirety of mathematics.
