¹⁵My arguments here are not very rigorous since the very definition of “control” is not made explicit in this book; I simply follow typical common-sense usage of the word. A more detailed analysis would point out that control is a matter of degree: In the context of this chapter, the explicit system has only partial control of the implicit system anyway because it merely directs its attention, so the explicit system is certainly not in total control in any meaningful definition of the word.
