“The Australian aborigines, reckoned to be among the most primitive of races upon evidence that is far from conclusive, have a region that is well-developed. They worship the Earth Mother, and recognise in their graceful, plaintive stories the prior existence of culture heroes as well limned as any in Valhalla. To an amazing degree they feel the reality of the metaphysical world they have created––the dream-time, which is neither a dream nor a period, or if it is a period is one which has no dimension, so that the past and the present exist together.”
