From the perspective of ontology, “creativity” contains two aspects: human beings are thinking creatively, and human beings are creators of thinking. Taking this as the ontological field of view, we get the understanding of the three dimensions of creativity in creative writing: firstly, the most fundamental dimension of creativity is a reproduction. Secondly, its higher dimension is the creation of things and emotional logic. Finally, the top-most dimension of creativity points to the “worldview”, which creates the meaning of the world. In this process, the author can be regarded as the creator of ideas. The creation method of the ontology of creativity is not intended to copy and imagine, but to create the world in accordance with the internal principles of the author. One of the crucial contributions of creative writing to literary theory is that creative writing regards the creative activity as an ontological creative practice rather than discussing it only from the perspective of social production. Establishing the creative creation methodology on the perspective of creative writing studies can provide the novel interpretation model and research path to study the latest practice of fiction writing. It can not only bring benefits for us to re-examine the creative nature of literary activities but also help us accomplish the renovation of the literary concepts, critical discourses, and research methods.
