 She would add for good measure that although human beings do engage in conscious and reflective thinking, most of our thinking is not of that sort. A human being is composed of a very large number of bodies, and most of these are involved in such orderly functions as the beating of the heart, digestion, the absorption of nutrients, the disposal of waste, reproduction, and the significant amount of communication that takes place between cells. That is a lot of mentality, and arguably it is much more than the mentality that is constituted by episodes of conscious reflection. Cavendish even offers a clever argument to the effect that episodes of conscious mentality of a human being presuppose a torrential amount of unconscious cognitive labor that is taking place behind the scenes.
