Hieronymi (2009) takes a very different line. She thinks that we engage in mental agency whenever we settle the question of whether to do or whether to believe something, and she argues that this kind of mental agency differs from ordinary intentional agency, primarily due to a difference in control. According to Hieronymi, we have “evaluative control” over our mental attitudes. This consists in the ability to form and revise “our take on things”, and it is to be distinguished from the kind of voluntary control that we have over our overt bodily actions. According to volitionist theories of agency, mental acts of willing (choosing or trying) are also different in kind from overt bodily actions. On such views, mental acts of willing are furthermore fundamental, in the sense that they are the source of overt agency (Ginet 1990; McCann 1998; Lowe 2008; more on this in section 3.1).
