1865.  Masson, Rec. Brit. Philos., iv. 344–5. If I were allowed to invent a term, I should say that Mr. Mill, cosmologically, is now a Cogitationist. The ultimate fact of the phænomenal world, as recognised by him, is neither Matter nor Mind in any present sense of these terms, but a cogitation or coagulation of phænomena which may be called feelings…. If we persevere in the analysis, we end in Cogitationism.
