Power is a web of force relations. It is everywhere because it comes from everywhere, not because it embraces everything.
Power is a relational, zero-sum game: If someone has more capital, others, by definition, have less.
Power is a relational concept... symbolic power exist only through circular relations of legitimization between agents endowed with large amounts of symbolic capital ('dominating agents') and agents that hold lesser amounts ('dominated agents').
Power is a stick in the hand, and with anybody who gets a very big stick in his hand, their brains run out the other end.
Power is able to exercise its greatest violence when it operates not as an in-your-face force, but when it parades as entirely insignificant, drawing no attention, and thereby foreclosing interpretation and or discussion.
