肇論新疏 2.345

2.345

道超名外，因謂之無；動與事會，因謂之有。因謂之有者，應夫真有，強謂之然耳。彼何然哉？

"The Way transcends outside of designations, and therefore it is called non-being; in motion it accords with affairs, and therefore it is called being. What is called being is forced to be called so only in response to true being. How could it be so of itself?"
