 Inasmuch as understanding always occurs against the background of our prior involvement, so it always occurs on the basis of our history. Understanding, for Gadamer, is thus always an ‘effect’ of history, while hermeneutical ‘consciousness’ is itself that mode of being that is conscious of its own historical ‘being effected’—it is ‘historically-effected consciousness’ (wirkungsgeschichtliches Bewußtsein). Awareness of the historically effected character of understanding is, according to Gadamer, identical with an awareness of the hermeneutical situation and he also refers to that situation by means of the phenomenological concept of ‘horizon’ (Horizont)—understanding and interpretation thus always occurs from within a particular ‘horizon’ that is determined by our historically-determined situatedness. Understanding is not, however, imprisoned within the horizon of its situation—indeed, the horizon of understanding is neither static nor unchanging (it is, after all, always subject to the effects of history). Just as our prejudices are themselves brought into question in the process of understanding, so, in the encounter with another, is the horizon of our own understanding susceptible to change.
