  We have contrasted PF judgments with AO or “all-out”  evaluative judgments. PF judgments are relational in character: they  point out a relation which holds between the consideration  r and doing a. (We could call that relation the  “favoring” relation.) That relation is not such as to  permit us to “detach” (as Davidson puts it, p. 37)  an unconditional evaluative conclusion in favor of doing a  from PF and the supposition that r obtains. That is, we are  not to understand PF judgments as having the form of a material  conditional.
