 He goes on to claim that that the use of pressure is manipulative only if the would-be manipulator directs it at some supposed weakness in his target that will render the target unable to resist it; this leads him to finalize his definition in terms of “deception or by playing upon a supposed weakness” of the target, with the second disjunct meant to cover pressure-based tactics (Rudinow 1978: 346). Several other philosophers have followed Rudinow’s disjunctive approach to defining manipulation (Tomlinson 1986; Sher 2011; Mandava &amp; Millum 2013). Indeed, as we have noted, it is common for people who discuss manipulative pressure to claim that manipulation comes in other forms as well.
