This is, of course, an overstatement. First of all, quantum gravity applies to the entire universe, not just its origins. If so, a careful philosophy of nature will have to take into consideration all the problems raised by such a theory, including those inherited from the philosophical problems of quantum mechanics. Second of all, the ‘demise’ of steady state cosmology may well be premature, since a number of cosmologists continue to construct models whose roots can be traced back to Hoyle’s early work. See for example H. C. Arp, G. Burbidge, F. Hoyle, J. V. Narlikar & N. C. Wickramasinghe, "The extragalactic Universe: an alternative view," Nature 346 (30 August, 1990), 807-812.
