引言
Introduction
「釋量論」是法稱論師為解釋陳那菩薩之「集量論」而造之義疏也。內容分為四品：第一、自義比量品，解釋立論者自身引生比量智必要條件（正因等）。第二、成量品，解釋「集量論」的歸敬頌義，成立如來為世間之定量。第三、現量品，現量乃比量所依止之基礎，本品廣釋現量之定義、差別及似現量等。第四、他義比量品，廣釋能立因等之得失，闡明使他人引生比量智之方便。本論總集因明理論之大成，為世間各國研習因明學之範本。在我國藏族佛教中已宏傳數百年，為學習教理必讀之書，而漢地佛徒尚無所知。余不揣駑鈍，茲將原文譯出，並依僧成大師之大疏，摘譯編成一部略解，其於漢族研究因明學者或略有所裨益焉。
The *Pramāṇavārttika* (*Treatise on Valid Cognition*) is a commentary composed by the great master Dharmakīrti to explain Dignāga's *Pramāṇasamuccaya* (*Compendium of Valid Cognition*). The text is divided into four chapters:
**Chapter One: Inference for One's Own Purpose** – This chapter explains the necessary conditions (such as correct reasons) for a debater to generate inferential understanding in their own mind.
**Chapter Two: Establishing Valid Cognition** – This chapter explains the meaning of the homage verse in the *Compendium of Valid Cognition*, establishing the Buddha as the ultimate authority for the world.
**Chapter Three: Direct Perception** – Direct perception serves as the foundation upon which inference relies. This chapter provides a detailed explanation of the definition, types, and apparent forms of direct perception.
**Chapter Four: Inference for Others** – This chapter extensively explains the merits and defects of the logical reasons used in arguments, clarifying the methods for helping others generate inferential understanding.
This treatise represents the culmination of the science of logic and reasoning (hetuvidyā), serving as a standard text for the study of Buddhist logic throughout the world. It has been widely propagated in Tibetan Buddhism for several centuries and is required reading for those studying Buddhist philosophy. However, it remains virtually unknown among Chinese Buddhists. Despite my limited abilities, I have undertaken to translate the original text into Chinese and, based on the great commentary by the master Gyaltso, have compiled a concise explanatory version. It is my hope that this may offer some benefit to Chinese scholars of Buddhist logic.
