 The process-oriented version of extended mind would interpret the case of Otto rather differently. There is no identification of a mental state with an external structure—a belief with a sentence. Rather, there is, first of all, a mental process. Describing this as a process of believing is, perhaps, a little forced: a process of remembering seems more apt. When Otto engages with, or manipulates, his notebook—flipping through the pages, and scanning each page—this manipulation forms part of his process of remembering the location of the Museum of Modern Art. This is only part of the process, of course: little remembering would get done without a suitable contribution from the brain. Nevertheless, Otto’s manipulation of the book is part of that process.
