As the name implies, it is the study of phenomena, and the key here is the understanding of "phenomena". The slogan of \x0d\ phenomenology is "back to the thing itself". The original intention of "phenomenon" is something that appears, and "thing itself" is generally understood as the ontology or essence hidden behind or deep in the phenomenon in traditional philosophy. Phenomenology understands phenomena as things themselves. "Appearance" is not only a manifestation of the senses, but also a temporary manifestation. Senses can only know the appearance or one side of things. First, they can't understand things themselves or their essence. In addition, the activities of consciousness and the appearance of things are no longer at the subjective and objective poles. \x0d\ "manifestation \" itself is already manifested in consciousness through conscious activities, so it is self-expression of consciousness. \x0d\ Therefore, phenomenology is the study of consciousness, which explains things themselves through the self-expression of consciousness. \x0d\ Phenomenology cannot be dominated by simple subjective or objective theories. \x0d\ He has the extreme subjective idealism of "everything is ready, only the east wind is needed" and the mirror subjective idealism of "everything goes to the Three Treasures Hall". \x0d\ Ponty put it well: the gain of phenomenology is nothing more than the combination of extreme subjectivism and extreme objective concern in the concepts of the world and rationality.
