[3] Turner was a theist and developed his idealistic philosophy in books such as Personality and Reality (1926) and The Nature of Deity (1927).
[1][4] In his book The Nature of Deity he used cosmological and teleological arguments as evidence for the Supreme Self.
[5][6] Philosopher John Stuart Mackenzie commented that Turner was "one of the most notable of the few remaining writers who carry on the tradition of Hegelian idealism" but noted it was doubtful that Turner could offer proof for the Supreme Self and that his statements were suggestive rather than conclusive.
