In Mohism, merit is defined as the quality or attribute that makes someone deserving of honor, reward, or recognition. It is closely linked to the concept of universal love, which is a central tenet of Mohist philosophy. According to Mohism, merit is not determined by one's social status, wealth, or power, but rather by one's actions and contributions to society.

In Mohist thought, merit is not something that is inherited or bestowed upon individuals by birth or social standing. Instead, it is something that is earned through one's actions and behavior. This aligns with the Mohist belief in meritocracy, where individuals are evaluated and rewarded based on their abilities and contributions, rather than their social status.

One of the key principles of Mohism is the idea of "gong," which can be translated as "merit" or "skill." This concept emphasizes the importance of developing one's skills and abilities, and using them for the benefit of society. In order to achieve gong, one must cultivate virtues such as sincerity, frugality, and diligence, and use them to serve the greater good.

Additionally, Mohism emphasizes the importance of self-improvement and self-cultivation in order to attain merit. This includes constantly striving to improve one's moral character and behavior, as well as acquiring knowledge and skills that can be used to benefit others. Mohists believe that through individual self-improvement, one can contribute to the betterment of society as a whole.

Furthermore, Mohism also places great importance on the concept of "yi," which can be translated as "rightness" or "justice." This refers to the idea that individuals should act in accordance with moral principles and do what is right, rather than what is self-serving. By acting with yi, one can earn merit and contribute to the overall harmony and well-being of society.

In summary, Mohism defines merit as the quality or attribute that is earned through one's actions and contributions to society. It is not based on social status or privilege, but rather on individual effort and moral character. By cultivating virtues, striving for self-improvement, and acting with yi, one can attain merit and contribute to the greater good of society.
