 Sellars claims the advantage that, through this social process of acquisition, sense impressions lose “absolute privacy” and become objects of intersubjective knowledge (1956: §62), and here he directly departs from  item 7  in the Classical Notion. But he has also rejected the acquaintance view of sense data as immediately present to the mind prior to learning  (item 2).  Sellars’s holistic conception that the acquisition of phenomenal concepts enables the ability to observe and self-report the presence of sense particulars may offer better reasons for rejecting item 2 of the Classical Notion than are found in his discussion of the inconsistent triad.
