 As regards  item 6,  that perceivers enjoy certainty in the apprehension of sensory ideas, a standard view has Descartes and Locke asserting or seeking such certainty (Rorty 1979: chs. 1, 3). This reading has been challenged for Descartes, Locke, and Berkeley (Yolton 1984: ch. 5; Hatfield 2011). Accordingly, the real hope for a prominent early modern conception that approaches the Classical Notion, especially as regards items 3 and 6, lies with Hume.
