 Another type of argument draws its inspiration from the phenomenological tradition. Wheeler (2005), for example, draws on the work of Heidegger (1927 [1962]) in defending a version of extended mind. Rowlands (2010), developing certain themes implicit in Husserl and Sartre, defends a model of intentionality as revealing activity: the presenting (revealing or disclosing) of an object as falling under a given mode of presentation. While the activity through which this presentation occurs can be purely internal—i.e., neural or neurocomputational activity—it need not be, and typically is not. Often this internal activity is combined with actions performed by an organism on the world around it. On this view, when Otto manipulates his book, he is engaging in revealing activity: The Museum of Modern Art is revealed, disclosed or presented as being located on East 53rd Street. This revealing activity comprises both activity occurring in Otto’s brain and wider activity performed by Otto on the world. As revealing activity, therefore, the process of remembering occurs partly inside Otto and partly outside him.
