Chemero spent Chapter 1 creating space for himself and his book in the marketplace of ideas about how we should do our cognitive science. Chapter 2 is about situating his theory in amongst the competition, with the goal of establishing exactly what a radical embodied cognitive science (RECS) is, and that it is a perfectly respectable competitor. He reviews a little history and an example study using dynamical systems that explains a 'representationally hungry' cognitive task to set things up. This is still quite preliminary work, but time well spent I think.
