 The most promising answer lies, once again, in the possibility that my grounds for rejecting a principle are not necessarily confined to its direct impact on my well-being. I might reject a principle requiring me to devote all my time and energy to charity, not simply because of the burdens it imposes on me but because, in leaving me no room for my own personal projects, it fails to respect me as a person. (The destitute person will reply that a principle allowing me to leave her to starve fails to respect her as a person. The challenge for the contractualist is to distinguish these two complaints. For one attempt, see Kumar 2000.)
