This paper is focused on investigating a principle of lyricism through the mirror neuron, which regarded as fundamentals for intercorporeality. In the mid-1980s, the mirror neuron, reasoned by the group of professor Giacomo Rizzolatti at Parma University in Italy, found out the biological mechanism for mimicry in the fundamental level. However, a series of discussion related to mirror neuron was easily brought to an ethical way. This study intends to comment on that and to connect a gap between neuropsychology and ethics. Mirror neuron can be illustrated as the first step for the intercorporeality in terms of being threatened by others impulsively and automatically. Physical resonance between one and others transforms and extends an experiential horizon each other. This is a previous stage for a willed moral behavior. Therefore, the rest of factors are considered in order to obtain the moral perspectives. To accomplish this task, this paper is planed to present will to transform for the other’s body, the sense of distance between I and others, and the futur-oriented perspectives toward the others as the answers. Considering these factors, mirror neuron eventually can be developed as the principle of lyricism.
