Therefore, if the ultimate Reality is mental, Causation must be Ontologically identical with Volition.
"Mind and Motion and Monism"
George John Romanes
For every sequence of mental changes and every sequence of cerebral changes, although phenomenally so diverse, are taken by this theory to be Ontologically identical; and therefore the sequence of mental changes must be determined with the same degree of 'necessity' as is that of the cerebral changes.
"Mind and Motion and Monism"
George John Romanes
That, therefore, is Ontologically absolute which is in some sense self-sufficing, independent of other things, in its existence; while the Ontologically relative is that which depends in some real way for its existence on something else.
"Ontology or the Theory of Being"
