In this paper I attempt to show Gadamer's theory of the relationship between the interpreter and the meaning of text. I shall argue that, for Gadamer, the text's meaning is always co-produced by the historical situation of the interpreter and that of the text. First, I introduce the Gadamerian concepts of hermeneutical circle and the historical situation of both the interpreter and the text. Second, I argue, in terms of three Gadamerian concepts: temporal distance, fore-conception of completeness, and fusion of horizons, that the text's meaning is co-produced by the historical situation of the interpreter and that of the text. Third, I analyze three kinds of "I-Thou relation" in order to point out that only with an open "I-Thou relation," can the interpreter and the text reach an agreement, which is also the meaning of the text. Finally, I argue that Gadamer's theory of the relationship between the interpreter and the meaning of text is in fact grounded on his view of the aim of hermeneutics.
