Interpretation as a way of speaking, understanding, and expression is a basic existence of phenomenon. Because it does not involve the truth problems , Hermeneutics has gradually evolved from explaining myths, classics, rhetoric, and textual criticism to the mainstreams of contemporary philosophy. In principle, it has undergone a history of transformation.In general, we can distinguish hermeneutics as classical hermeneutics and philosophical hermeneutics; the former represented is Shilai Friedrich Daniel Ernst Schleiermacher (1768~1834) and Wilhelm Dilthey (1833~1911); the latter are Heidegger (1889~1976) and Hans-Georg Gadamer 1900~2002). I wanted to find the research method of Buddhism use interpretation philosophical hermeneutics especially on Hans-Georg Gadamer point.
