ABSTRACT
In this chapter, I try to reconcile an inconsistency between Sellars’s ethical theory and his larger philosophical project. Sellars rejects formalism in theoretical reasoning, arguing
This dry, well-made match is struck
Therefore, the match will light
is a good inference and doesn’t depend for its validity on the insertion of a major premise. In ethics, though, Sellars seems to embrace this formalism, arguingI am in Ci
Therefore, Shallwe [I do Ai]
is good qua instantiation of the intermediate moral principleShallwe [I do Ai if in Ci]
which in turn is good only if derived from the supreme principle of moralityShallwe be [Our welfare is maximized]
This formalism is inconsistent with Sellars’s other commitments. We should recognize that intermediate moral principles have original (but not foundational) authority; they are “auxiliary moves,” as described in “Some Reflections on Language Games.” But there is still a role for the supreme principle of morality: It is a theoretical postulate that serves a dialectical role to resolve disputes among mid-level intermediate moral principles and to bring consistency into our moral practice. Thus, we can preserve the formal structure of Sellars’s ethical theory while preserving his opposition to formalism per se.
