 Gilbert’s later statements become more explicit about the directed nature of these non-moral obligations (Gilbert 1997, 75–6). The obligation relates Jack with Sue in a way in which Jack and a non-participant are not related (Gilbert 2009; 2008, 497; this connects with recent discussion of “bipolar normativity”; see Darwall 2006, Thompson 2004, and Wallace 2013). To mark the directed nature of the normative relation, and in a way that does not suggest as strongly that they are moral in nature, we might speak of contralateral commitments (Roth 2004). Thus, Jack has a contralateral commitment-to-Sue to walk in a way that is compatible with their walking together.
