 In some cases, one might not be confident that one can arrange for external incentives that will get one’s future self to voluntarily cooperate with one’s current plans. One might therefore favor the related but more extreme strategy of making sure that one’s future self does not have the power to thwart one’s current plans. Rather than simply making cooperation more worthwhile (and thus, in a sense, more compelling), this strategy involves arranging for the use of force (which compels in a stronger sense of the term). A fictional but particularly famous employment of the strategy (which is discussed in, for example, Elster 1984) is its employment by Odysseus in Homer’s Odyssey. Because he longed to hear the enchanting singing of the Sirens, but feared that he would thereby be lured into danger, Odysseus instructed his companions to tie him to the mast of his ship and to resist his (anticipated) attempts at freeing himself from the requested bonds.
