  There are good reasons to treat coercion via the will and direct force or constraint applied to the body as two methods of a single kind of activity. First, though direct force is usually unsuited to get an agent to perform a specific action, both are well suited to preventing an agent from taking a variety of actions, with direct force or constraint often being more decisive. Second, the two techniques are often used hand-in-hand. For instance, police officers will shackle and manhandle someone in custody who refuses to cooperate when given instructions to move or stay still. Also, prison inmates are coerced into remaining there by a combination of penalties for attempting escape along with physical obstacles that limit the feasibility of doing so. So using both techniques is often part of one and the same activity aimed at affecting or constraining what an agent will do (sometimes by affecting what she can do) (Anderson 2008a and 2010). Of course, under direct force, it will usually be true that the coercee does not act, but rather is acted upon, as H. J. McCloskey puts it (McCloskey 1980).  However, from the coercer's perspective, it may be just as well, in enforcing his decisions, to prevent the coercee from acting at all as it would be to induce her to choose not to act.
