Hans-Georg Gadamer on being aware of your bias as a reader (Truth and Method, 271-272):
…a person trying to understand a text is prepared for it to tell him something. That is why a hermeneutically trained conciousness must be, from the start, sensitive to the text’s alterity. But this kind of sensitivity involves neither “neutrality” with respect to the content nor the extinction of one’s self, but the foregrounding and appropriation of one’s own fore-meanings and prejudices. The important thing is to be aware of one’s own bias, so that the text can present itself in all its otherness and thus assert its own truth against one’s own fore-meanings.
What is great about this is that unlike Schleiermacher, and many who live in his hermeneutical paradigm, the reader doesn’t have to buy into the lie of objectivity. Hermeneutics demands engagement that includes the reader which includes the presuppositions of the reader. What cannot be missed is that the reader must be self-aware, if possible, acknowledging prejudice brought to the text.
