Mohism, founded by Master Mo (Mozi), was one of the most significant philosophical schools of ancient China, placing the idea of universal love and obedience to the Will of Heaven at its core. This philosophy emphasized universal utilitarianism, positing that loving and respecting all people without exception leads to mutual benefit, peace, and social order. Mozi was a staunch opponent of aggressive and offensive warfare, highlighting its immoral nature, destructive impact on the economy and society, and contradiction with the divine order. He criticized the political elites of his time for their inability to distinguish justice from injustice and for portraying bloody conquests as glorious achievements. As an exception to his pacifist doctrine, Mozi permitted so-called punitive expeditions, viewed as justified interventions against despotic rulers to restore peace and order. Recognizing the inevitability of conflicts, the philosopher placed great emphasis on preparing for defensive warfare, including the development of military technology, fortifications, and active diplomacy. Mozi's timeless teachings offer a utopian yet profoundly valuable vision of a world free from war, where justice and mutual care define the standards of governance.
