Abstract

Wilfrid Sellars attempts to deflect traditional objections to the straight rule of inductive acceptance by embedding it in a complicated system of levels. This system rests on a theory of probability in which the meaning of "probable" is reconstructed in the context of Sellars' general theory of practical reason. To say a statement is probable means, according to Sellars, that there is good reason for accepting the statement as true. In this paper I examine Sellars' attempt to resuscitate the straight rule and conclude that not only does he fail, but his account of "probable" is circular.
