Knowledge/Sellars: (McDowell) should be located in a normative context. "Space of reasons." But sensations do not belong to the space of reasons.
Sensations, empiricism: are not in the same space as knowledge.
Sensations are not in such a space, in which the one would be justified by the other. (Otherwise naturalistic fallacy).
Knowledge/Modern/McDowell: Knowledge has normative status for us. (Not for Aristotle).
