The dialectical method of Buddha is a distinctive philosophical approach based on rational inquiry, critical examination, and practical realization rather than mere speculation or dogmatic acceptance. In the context of research methodology in philosophy, it represents a systematic process of investigating truth through dialogue, questioning, logical analysis, and experiential verification. Unlike many metaphysical systems that sought absolute explanations of reality, Buddha emphasized the examination of human experience and the elimination of suffering through intellectual and moral discipline. The dialectical method of Buddha begins with the principle of free inquiry. He encouraged individuals not to accept any doctrine simply because it was supported by tradition, scripture, authority, or popular opinion. Instead, every claim should be critically examined in the light of reason and personal experience. This spirit of inquiry is clearly reflected in the advice given to the Kalamas, where Buddha urged people to test teachings before accepting them. Thus, knowledge is established through investigation rather than blind faith. Dialogue occupies a central place in Buddha’s dialectical method.
