There is every appearance that the author was a Hellenist who lacked knowledge of the Hebrew text, and derived his metaphysic and his allegorical method from the Alexandrian rather than the Palestinian schools.
He avers that this " metaphysic of experience " is not idealism, or the tenet that consciousness is the only reality.
In its metaphysic it showed no failure in dialectical constructiveness.
Huxley (Science and Culture) and Shadworth Hodgson (Metaphysic of Experience and Theory of Practice), must be distinguished from that of the psychophysical parallelism, or the "double aspect theory" according to which both the mental state and the physical phenomena result from a so-called "mind stuff," or single substance, the material or cause of both.
A similar metaphysic from a different starting-point is found in Heraclitus, who postulates behind the perpetually changing universe of phenomena a One which remains.
