Thus the old adage operari sequitur esse (action follows being) must be modified by saying that to be is to act, and only that which acts-the active-exists, and in so far as it acts.
Eta honela, operari sequitur esse, ihardutea izateari darraio, delako esaera zaharra aldatu beharra dago, izatea ihardutea dela esanez, eta diharduena besterik ez dela existitzen, hots, aktiboa, eta diharduen neurrian.
