Which major philosophers developed their ideas during the Warring States period?

The Warring States period (475–221 BCE) was a remarkably fertile era for Chinese philosophy, characterized by the "Hundred Schools of Thought" as thinkers competed for influence among provincial rulers.12

Key philosophers and schools that developed during this time include:

• Confucianism: Following the death of Confucius, his followers split into various schools. Major Confucian thinkers of the Warring States period include Mencius, who defended Confucian ideals against competing ideologies, and Xunzi.32
• Legalism: This school focused on state power, strict laws, and absolute authority. Prominent figures included Shang Yang, Hanfeizi, and Li Si.4
• Mohism: Founded by Mozi, this school challenged Confucianism by advocating for "love without distinctions" (jianai) and criticizing the emphasis on elaborate rites.53
• Daoism: Early Daoists often lived as hermits, focusing on a contemplative life in nature. The period also saw the rise of the Yang Zhu, known for his individualistic philosophy, and later the Huang-Lao tradition, which drew upon the teachings associated with Laozi.36
