Thought

This one's a bit deep, but it explains a lot. Hmm..
"For a long time, I have been trying to see if it would be possible to describe the history of thought as distinct both from the history of ideas (by which I mean the analysis of systems of representation) and from the history of mentalities (by which I mean the analysis of attitudes and types of action [schémas de comportement] ). It seemed to me there was one element that was capable of describing the history of thought — this was what one could call the problems or, more exactly, problematizations. What distinguishes thought is that it is something quite different from the set of representations that underlies a certain behavior; it is also quite different from the domain of attitudes that can determine this behavior. Thought is not what inhabits a certain conduct and gives it its meaning; rather, it is what allows one to step back from this way of acting or reacting, to present it to oneself as an object of thought and to question it as to its meaning, its conditions, and its goals. Thought is freedom in relation to what one does, the motion by which one detaches from it, establishes it as an object, and reflects on it as a problem."
