Note 38 — Chapter XVII
Reading edition
"Especially must we avoid all attempts, whether avowed or concealed, to account for the spatial qualities of the presentations of sense by merely describing the qualities of the simple sensations and the modes of their combination. It is position and extension in space which constitutes the very peculiarity of the objects as no longer mere sensations or affections of the mind. As sensations, they are neither out of ourselves nor possessed of the qualities indicated by the word spread-out." (Ladd, op. cit. p. 391.)
