Since the practitioner's value sense is the essential strength that promotes academic practice, the reflection and reconstruction of communication scholars' own value and mission constitute an important perspective for reflecting upon and reconstructing the communication discipline. Based on Johann Gottlieb Fichte's value philosophy about scholars' mission and a historical view of communication discipline, this paper analyzes the puzzles and difficulties for self-fulfillments that communication scholars may confront when choosing the communication discipline as their major. We first begin by solving the communication ontology puzzle and then integrate the positive and clear self-understanding and self-reflection consciousness into the ontological construction of communication knowledge. This means proposing a new way for understanding communication scholars' value and mission, thus providing more creative motivation for their own academic practice.
