Reduktion, redução, reducción, reduction

The summer semester course of 1927, The Basic Problems of Phenomenology (§5), develops a threefold distinction within the phenomenological approach. The move away from beings and the ontic (for example, the empirical sciences) to their being (to their regional ontologies and then to fundamental ontology) is called reduction; the actual projection of beings onto their ontological structures is construction (= the systematic); and the dismantling of the historically transmitted concepts in which their being is customarily described in order to get back to the experiential sources from which they are drawn, is destruction (= the historiological). These three elements of the phenomenological method are regarded as co-original or equiprimordial, that is, as belonging essentially together in reciprocal equality. (Kisiel; GA20TK)

The summer semester course of 1927, The Basic Problems of Phenomenology (GA24:§5), develops a threefold distinction within the phenomenological approach. The move away from beings and the ontic (for example, the empirical sciences) to their being (to their regional ontologies and then to fundamental ontology) is called reduction; the actual projection of beings onto their ontological structures is construction (Konstruktion) (= the systematic); and the dismantling of the historically transmitted concepts in which their being is customarily described in order to get back to the experiential sources from which they are drawn, is destruction (Destruktion) (= the historiological). These three elements of the phenomenological method are regarded as co-original or equiprimordial, that is, as belonging essentially together in reciprocal equality. (Kisiel; GA20TK)
