Where a Conceptualist says that a name or a proposition expresses our Idea of a thing, I should generally say (instead of our Idea) our Knowledge, or Belief, concerning the thing itself.
1855. Milman, Lat. Chr. (1872), IV. 365. John of Salisbury, in his Polycraticus, is a manifest, if not avowed Conceptualist.
