在书信中,已知宇宙也是和无限大的宇宙整体相区别:
As for cosmic matters—I think a little reflection will shew you that the absence of any beginning or ending is not only not difficult to grasp,but that the opposite conception is absolutely impossible either to graspor seriously believe. If all entity had a beginning & will have an ending,then what began it, & what began the beginner at one end, & what will non-entity be after its conclusions? These assumptions of finiteness are all puerile & arbitrary, & based on the mythology of the past. In theabsence of any information beyond relatively narrow limits, the only reasonable adult assumption is that the space-time continuum represents a fixed & basic condition. It is all there is, has been, or will be anywhere. It is the primal essence of reality. It is fundamental entity, infinite &eternal, whose patterned rearrangements are an integral part of its properties, & of which 【the visible universe & human life are a negligible quasi-atom】 casually spawned for an instant & soon to be as though they had never been . But probably life as a basic principle is not peculiar to this part of space—though we might not recognise many of its otherforms as being life at all.——《SELECTED LETTERS Ⅴ》.Arkham House, 1976.p22-23
