[4]: p188 David Malet Armstrong "suggested, half-seriously, that 'the strong sunlight and harsh brown landscape of Australia force reality upon us'".
[5] Australian realism began after John Anderson accepted the Challis Chair of Philosophy at the University of Sydney in 1927.
Anderson viewed philosophy historically as a long argument beginning with Thales.
Anderson proposed that there was nothing more to being than the spatio-temporal system and that a correct and coherent view of the world involved not only rejecting any sort of deity, but also the extraordinary entities postulated by so many philosophers, from at least the time of Plato to the present day.
[7] James Franklin and the "Sydney School" develop the Anderson-Armstrong "one level of reality" view into a philosophy of mathematics that is opposed to both Platonism and nominalism.
