Abstract:In the first place, health is a concept in medical science and sports science, but as a value word, it can be categorized into somaesthetics. “Heath” in somaesthetics is different from “fitness” in sports aesthetics as fitness is only the state of being physically healthy and strong while health applies to all aesthetic objects including art. The concept of health has been widely used in literary criticism (such as by Goethe, Dana and Liang Shiqiu), but has not been elevated to aesthetic level. Nietzsche initially proposed health as an aesthetic concept, which made him a pioneer in somaesthetics. However, Nietzsche defined health with “power”, which means that the subject dominates the object and obviously fails to reveal the essence of health. Nietzsche's philosophy is still shackled by subjective metaphysics, which is the root cause of decline and morbidity. Phenomenology transcends subjective metaphysics rising above the opposition between subject and object,and the opposition between internal world and external world. On the basis of phenomenology, “health” as an aesthetic concept possibly came into being.
