Meantime, when once we know from nothing still Nothing can be create, we shall divine More clearly what we seek: those elements From which alone all things created are, And how accomplished by no tool of Gods.

– Titus Lucretius Carus: ‘On the Nature of Things’, Book 1 (‘Substance is External’, ‘The Void’, ‘Nothing Exists per se Except Atoms And The Void’). See Marshall Clagett: ‘Greek Science in Antiquity’ 1955 and revised 1963.

Although yu, yet wu. Although wu, yet yu. “Although yu, yet wu” is a denial of Being. “Although wu, yet yu” is a denial of nothingness. In this way, it is not that there is no thing, but that things are not truly (substantial) things. If things are not truly (substantial) things, in what way are they “things”?
