The Shape-of-a-Life phenomenon is widely recognized by philosophers of well-being: an upward life trajectory seems better than its downward equivalent if the sum of momentary well-being is held fixed. But what if we hold fixed the sum of momentary well-being in an upward trajectory, are certain ways to improve from the bad times better than the others? Velleman suggests that a redemptive trajectory is better than a bare upward trajectory. In this paper, I elaborate this proposal by developing a mediating factor account of prudential redemption. I argue that, in redemptive trajectories, there is a mediating factor that bears certain relations with the negative and the positive events respectively, one that does not necessarily appear in bare upward trajectories. Prudential redemption, compared to mere improvement, can enhance a person’s lifetime well-being because a redeemed event is made less bad by virtue of the mediating factor. This result has implications for making decisions in the face of equally good options and for evaluating the rationality of honoring sunk costs.
