Hàn Phi Tử: Tư Tưởng và Sách Lược (Han Fei: Thought and Strategy)

This Vietnamese edition presents the core writings of Han Fei (Hàn Phi Tử), the 3rd century BCE Chinese philosopher regarded as the definitive synthesizer of Legalist (Pháp gia) political thought, organized around his central argument that a stable, prosperous state must be governed through impartial law rather than through the virtue, wisdom, or personal charisma of individual rulers. Writing during China's turbulent Warring States period, Han Fei set out to solve a practical problem: how does a state survive and govern effectively when it cannot count on always having a wise or virtuous ruler at its head?

His answer, developed across the text, is a integrated system built on three interlocking concepts: Pháp (法, law) — codified, publicly known, uniformly enforced rules that apply regardless of rank; Thế (勢, position or power) — the structural authority and strategic position a ruler occupies, which must be actively maintained rather than assumed to be automatically respected; and Thuật (術, method or technique) — the practical statecraft methods a ruler uses to evaluate officials, verify their claims against their actual performance, and prevent being deceived or manipulated by subordinates. Han Fei argues that these three elements must work together: law without enforceable position is toothless, position without method invites manipulation by scheming ministers, and method without codified law degenerates into arbitrary personal control.

The text is notably skeptical about human nature and about the reliability of virtue-based governance, a direct challenge to the Confucian orthodoxy of his time, which emphasized moral cultivation and the example of a virtuous ruler as the foundation of good government. Han Fei, having studied under the Confucian philosopher Xunzi (who himself held a relatively pessimistic view of human nature), pushed this skepticism further, arguing that a system of government should be built to function reliably even when staffed by ordinary, self-interested people — including mediocre rulers — rather than depending on the rare appearance of a sage-king.

The book's practical sections work through applied statecraft: how a ruler should test whether officials' words match their actions (a doctrine sometimes rendered as "using performance to hold officials to their words"), how to prevent ministers from concealing information or building independent power bases, and how clear, consistently enforced law prevents the arbitrary favoritism that breeds resentment and instability. Han Fei's own biography adds a sharp irony to the text: despite his warnings about court intrigue and betrayal by rivals, he was reportedly slandered by a fellow student of Xunzi, Li Si, and died in prison in the state of Qin — the very state whose ruler, later the First Emperor, would go on to adopt Legalist principles derived substantially from Han Fei's writing to unify China.
