 Finally, since these rights are not granted by institutions, created by any contractual process, or accorded to individuals for the sake of advancing some optimal social outcome, if they have any foundation, that foundation must consist in some morally impressive fact about the nature of individuals qua individuals. Some morally impressive fact about the nature of individuals—e.g., that they each have ends or projects of their own to which they rationally devote themselves—must provide others with reason to not treat them certain ways, e.g., as beings who ought to serve the ends of others. We shall see that Nozick advances a claim of this sort in his account of why agents should abide by moral side-constraints in their conduct toward others.
