For Gadamer, we exist neither in closed horizons, nor within a horizon that is unique; we must reject both the assumption of absolute knowledge, that universal history can be articulated within a single horizon, and the assumption of Objectivity, that we can "forget ourselves" in order to achieve an objective perspective of the other participant.
Gadamer argues against both closed horizons and a singular, objective perspective. He rejects the idea of absolute knowledge and the assumption of objectivity.
