Zhuangzi, also romanized as Chuang-tzu and also known as Zhuang Zhou, was a Chinese Taoist philosopher who lived during the Warring States period, roughly in the fourth to third centuries BCE. His personal name was Zhou, and the honorific “Zhuangzi” means “Master Zhuang.” Although historical details of his life are sparse and often tinged with legend, he is associated with a modest official post and with later withdrawing from public life to devote himself to reflection and writing. Within the Taoist tradition he stands as one of its most important figures after Laozi, not so much as a system-builder but as a sage-writer whose voice is at once playful, penetrating, and profound.

The text that bears his name, the *Zhuangzi* (also known as the *Nanhua Jing*), is one of the foundational works of Taoist literature, standing alongside the *Tao Te Ching*. It is a collection of stories, dialogues, parables, and poems that develops and radicalizes central Taoist themes. Through these narratives, Zhuangzi explores spontaneity, naturalness, and alignment with the Dao, while expressing a deep skepticism toward rigid moralism, political ambition, and narrow rationalism. The work repeatedly emphasizes freedom from artificial social constraints and the cultivation of a life in harmony with the natural order.

Philosophically, Zhuangzi is renowned for his reflections on *wu wei* (non-forcing or effortless action) and *ziran* (naturalness or spontaneity), as well as for his insistence on the relativity of distinctions and judgments. He challenges fixed oppositions such as self and other, right and wrong, life and death, suggesting that ultimate reality transcends the categories through which human beings habitually grasp the world. Famous passages such as the butterfly dream and the dialogue on the happiness of fish use humor, paradox, and fantasy to unsettle conventional certainties and to invite a more fluid, open way of seeing.

Zhuangzi’s style is as significant as his doctrines. His use of vivid parables, irony, and imaginative scenarios does not merely decorate his thought; it enacts the very freedom and playfulness he advocates. Rather than prescribing a rigid path, his writings gesture toward a way of being that is simple, uncontrived, and attuned to the ever-changing flow of things. Over the centuries, this combination of literary brilliance and philosophical depth has profoundly shaped Taoism and exerted a lasting influence on Chinese philosophy, religion, and literature.
