Annoyed by Foucault

I'm reading this introduction to Foucault, and it *seems*, sometimes, as if Foucault could be rather useful in discussing Finder... but I'm sadly incapable of really understanding almost anything. I mean, I get these sort of... vague *glimpses* of What It All Means, here and there, but they're interspersed with lots of Really Dense, Really Incomprehensible Philosophy - I can read entire pages without understanding a single sentence. Much like my attempt to read/understand some Judith Butler a few months ago, this foray into theory seems doomed by my too-low intelligence (or my lack of years and years of previous experience reading philosophy).

I wonder - is there any theory that might be useful for my thesis that is actually comprehensible to a student of only *slightly* above average intelligence and not a lot of experience reading philosophy? I get the impression that even most of the introductions to the great theorists are written for people who already have a fairly good grasp of the canon of great thinkers of the past two centuries or so, and/or a much higher IQ than me.
