Heidegger shifts physis first towards the verbal mode – phyein ϕυειν or growing, to make grow. Here he implicitly reflects or anticipates the ‘danger’ of regarding his term Greatness or great as merely a quantitative indicator. “Doch was heißt wachsen? Meint es nur das mengenmäßige Zu-nehmen, mehr und größer Werden?”(“But what does it mean to grow? Does it only mean the quantitative increase, to become more and greater?”) Without really answering this question of what is growth – Heidegger persists in his infra-mince distinction between physis as “opening up (rising)”, the motion or mode of natural phenomenon such as sunrise, the tides, growth of plants, “going forth of animals and humans from the womb (Schoß)” and everywhere else in nature and that other physis – not observable in nature or on beings (Seiende). The second Heideggerian physis, denoted as an opening up that prevails, reigns is not a natural process. Finally, relieving the suspense, Heidegger identifies the second physis as “das Sein selbst” or Being itself – by whose power any being can first become and remain observable.
