Noun edit

besideness (uncountable)

  1. (chiefly philosophy) The quality of being beside.
    • 1977, Nelson Goodman, The Structure of Appearance:
      Clearly, matching is a necessary condition for besideness in a category, since if two qualia of a category fail to match there is still an M-path joining them and consequently one or more qualia lying between them.
