The word 人性 is formed through a conceptual synthesis of its two component characters: 人 (rén), meaning "human" or "person", and 性 (xìng), meaning "nature", "character", or "inherent quality". It is not merely a sequential combination but a fusion where the first character specifies the realm (the human) and the second character provides the abstract category (essential nature). Together, they create a new, unified philosophical concept, "human nature", that refers to the fundamental, shared characteristics and moral qualities intrinsic to humankind, an idea deeply rooted in classical Chinese thought.
