The point is not simply that knowers are capable of metajudgments. Sellars has a larger condition in mind: “The essential point is that in characterizing an episode or a state as that of knowing, we are not giving an empirical description of that episode or state; we are placing it in the logical space of reasons, of justifying and being able to justify what one says” (EPM: §36, in SPR: 169; in KMG: 248).  This dictum needs to be combined with another well-known Sellarsian pronouncement: “Now the idea that epistemic facts can be analysed without remainder—even ‘in principle’—into non-epistemic facts, whether phenomenal or behavioural, public or private, with no matter how lavish a sprinkling of subjunctives and hypotheticals is, I believe, a radical mistake—a mistake of a piece with the so-called ‘naturalistic fallacy’ in ethics” (EPM: §5, in SPR: 131; in KMG: 209).
