Gordon is a Canadian philosopher of science (physics), metaphysician and philosopher of religion. A person who creates or develops metaphysical theories is called a "metaphysician".

Accordingly, Cudworth, the most systematic metaphysician of the Cambridge Platonist tradition, fought hylozoism. Schiller's accusations against the metaphysician in "Riddles" now appear in a more pragmatic light. The narrator then reveals that this is a quote from the amateur metaphysician Dionis. Ada described her approach as "poetical science" and herself as an "Analyst (& Metaphysician)". As a metaphysician, Parvu published the two-volume "The Architecture of Existence".
