Philosophical Roots: The concept of 良心 is deeply influenced by Confucianism, particularly the teachings of Mencius (孟子), who believed that humans are innately good (性善説, xìngshànshuō). This innate goodness is the source of one's 良心. It's the internal compass that, if followed, leads to virtuous behavior like benevolence (仁, rén) and righteousness (义, yì).
Comparison to Western “Conscience”: In Western culture, “conscience” can sometimes be an abstract, individualistic, or even guilt-ridden concept (e.g., a “guilty conscience”). It is often framed as an internal struggle between the self and a moral code. In contrast, 良心 is profoundly social and practical. A person's 良心 is judged almost entirely by their actions and their impact on others—their family, their community, and society at large. Lacking 良心 isn't just a personal failing; it's a social crime, a betrayal of the trust that holds society together.
Related Values: Acting with 良心 is directly tied to core Chinese values like social harmony (和谐, héxié), trustworthiness (信用, xìnyòng), and filial piety (孝, xiào). For example, a child who takes good care of their elderly parents is said to have 良心. A business that sells safe, high-quality products is called a “良心 enterprise” (良心企业, liángxīn qǐyè).
