People have a capacity to imaginatively recreate mental states that they themselves do not have. These recreative states are referred to as ‘I-states’. Several philosophers, such as Gregory Currie, Tyler Doggett, and Andy Egan, propose that the combination of i-desire and i-belief—two typical I-states—can motivate agents. The goal of this paper is to defend this i-desire + i-belief account. Here I consider a kind of dramatic acting—method acting—in which an actor aspires to sincere performances by experientially inhabiting the role of (...) the character, as involving I-states and that it implies that i-desires and i-beliefs can motivate agents. First, I analyze the features of method acting; second, I argue that those accounts which do not include the concept of i-desire cannot explain these features; third, I argue that the i-desire + i-belief account can do that and it therefore is the best explanation of how a method actor is motivated on stage.
