In this blog post, we will examine how the theory of calamities interpreted the relationship between Heaven and humanity, and what impact it had on East Asian politics and culture.
The theory of calamities is a representative East Asian discourse that explains natural phenomena and human affairs through causal relationships. During the Han Dynasty, Dong Zhongshu systematized the theory of calamities by combining the “Heavenly Punishment Theory”—which posits that Heaven sends calamities to rebuke rulers who have lost their virtue—with the “Heaven-Human Resonance Theory,” which holds that Heaven and humanity mutually resonate through the shared Yin-Yang Qi. According to this theory, when a ruler commits misrule, Heaven responds through the altered Yin-Yang Qi caused by such misrule, issuing warnings in the form of disasters such as droughts, floods, solar eclipses, and lunar eclipses. In this context, disasters served both to demonstrate that the ruler’s authority derives from Heaven and to warn the ruler of his misrule.
These fundamental concepts of the theory of natural disasters became a crucial framework for explaining the relationship between politics and natural phenomena in East Asian societies. According to the theory, a ruler’s actions that defied the will of Heaven inevitably brought about disasters, which were interpreted as warning messages sent by Heaven to humanity. Consequently, rulers felt compelled to reflect on and improve their methods of governance in response to these disasters. This served as a methodology for achieving political stability and social harmony.
The dual nature of the theory of calamities provided ministers with a justification for participating in political discourse, and it crystallized into a tradition whereby, when a calamity occurred, the ruler sought frank advice and the ministers responded accordingly. However, the individualistic approach—which, following Dong Zhongshu, explained natural disasters as direct consequences of human affairs—was criticized as overly forced. This approach even led to a tendency toward prophecy, creating a trend of viewing natural disasters as omens of human affairs and human affairs as the results of natural disasters. It also provided a pretext for rulers to suppress ministers who offered frank advice, accusing them of misleading the people with unfounded claims.
Subsequently, prophetic interpretations of calamities became the subject of criticism, and the theory of heavenly-human resonance was also rejected. Nevertheless, the theory of calamities did not disappear from the political arena. By the Song Dynasty, Zhu Xi accepted the tendency not to regard solar and lunar eclipses—which had become predictable due to advances in astronomy—as calamities, and viewed calamities as natural phenomena that were fundamentally difficult to explain through rational principles. However, even at that time, the abandonment of the theory of celestial omens—which had encouraged active responses from the monarch and provided opportunities for safe free speech—meant that ministers would lose a useful political mechanism.
For this reason, he adhered to the theory of celestial omens in order to find an appropriate method to keep the monarch in check. Instead of advocating for individual responses to celestial omens, he proposed a general theory of response, arguing that if a ruler’s faults and mistakes accumulated, Heaven would respond by causing anomalous natural phenomena. By framing celestial omens as a matter of the ruler’s moral cultivation, he extended the historical lifespan of the theory of celestial omens. Through this, the theory of celestial omens transcended a mere explanation of natural phenomena to serve as a crucial standard regulating the ruler’s moral responsibility and political conduct.
The influence of the theory of calamities was not limited to the political sphere. It fostered a social climate that emphasized moral norms across society and had a significant impact on education and culture. For example, ethics education based on the theory of calamities was strengthened in schools, and narrative structures and themes influenced by the theory frequently appeared in literary works. This cultural diffusion established the theory of calamities as a significant ideology that was widely accepted and understood throughout society, transcending the realm of mere political theory.
Furthermore, the theory of calamities contributed to a certain extent to the scientific thinking and understanding of natural phenomena of the time. Attempts were made in various academic fields, such as astronomy and meteorology, to analyze and predict natural phenomena by referencing the Theory of Heaven, which served as a crucial foundation for the development of science in East Asia. These academic advancements provided valuable knowledge to later researchers and remain examples of the Theory of Heaven’s enduring influence.
In conclusion, the Theory of Rectitude was a crucial theory in East Asia that systematically explained the relationships between politics and nature, as well as between humanity and the heavens. It went beyond merely defining the relationship between rulers and subjects, playing a role in promoting moral norms and academic development across society as a whole. The influence of the Theory of Rectitude remains a significant research topic for many scholars today and occupies an indispensable position in the history of East Asian thought.
