Abstract
According to an old way of thinking, any leve! of problematicity with respect to truth or theory dependence suffices to spoil the objectivity of a proposal. No credible discourse complies with such restrictions. Far from compromising the existence of knowledge, correct and incorrect, rational and nonrational ideas, however. the said old way of thinking is simply incapable of representing the cognitive achievements that we actually have. This paper discusses a contemporary way of approaching the difference between ideas of high and low descriptive quality in terms of epistemological criteria that prevail in the most rigorous and reliable scientific practices
