One of Gadamer's major themes is the need to acknowledge the significance of the subjective self in any act of understanding. He explores this theme with reference to what he terms "the power of prejudice ", by which he means the power that is exercised by our prior assumptions or "pre-judices' ("das Vorurteil"). It is this "power of prejudice" that calls into question the claims of scientific "objectivity ". The subjective element that Gadamer identifies as an essential element in human understanding finds expression in the specificity of the questions we ask. Understanding is—from a Gadamerian perspective—achieved through the formulation and pursuit of questions that are unique to whoever is posing them: our questions are shaped by what we find uniquely meaningful in that which our questions are addressing. In becoming educated we become, therefore, more fully ourselves. We flourish. Education is centrally concerned with human flourishing : with each realising her or his full potential .
