Modern science and technology separate human beings from nature and regard the nature as a machine. It is an atomistic and causal ontology or a world view. But The fourth industrial society should modify existing ontologies. These societies are the connected society that binds human beings and human beings, human beings and objects and human beings and the nature. In the era of the Fourth Industrial Revolution, the cultural and spatial characteristics that define human beings will gradually disappear and enter into a new relationship based on digitalization. This relationship may need to explain a new human identity.\nThe new digital society is fundamentally changing the relationship between human beings and human beings, human beings and society. A new society must acknowledge the relationship between man and things on the ontology. As a philosopher who responded to the changes of the new era, We tried to study through Wang Yang-Ming and Merleau-Ponty. Because the two philosophers denied the atomistic and mechanistic view of the world or ontology and acknowledged the ontology or the view of world that binds human beings, objects and nature together. Through the ontology of the traditional philosophers, Wang, Yang-Ming and Merleau-Ponty, we searched for the clues of the ontology that responds to the era of the Fourth Industrial Revolution.
