Eidetic reduction

Eidetic reduction (Greek = εἶδος the show, the looking or essence (Plato ) and Latin reductio = recycle ) is a term and a method of Edmund Husserl's phenomenology, in which the essence of a phenomenon is made detectable.


The phenomenology assumes that complicated truths are constructed from simpler ones, which in turn consist of even simpler. The endpoints of this reasoning chain are called phenomena. So there is the first task of methodological thinking in recourse to evident phenomena, which are given by the intuition with absolute certainty. This recycling of the factual characteristics of the " intentional experiences " and their objects on the eidetic determination that underlies them and for which the actual characteristics are only exchangeable examples, Husserl calls eidetic reduction. It is of great importance that any unsecured judgments is included. This means that while the phenomenological reflection everything that needs to be hidden, which does not belong to the essence ( eidos ), the Epoché must be universal.

Kurt Wuchterl identifies five areas that are hidden in this process:

Since humans have the ability to directly detect a reality in intuition, the essence will recorded separately from the above-mentioned areas. These beings show brings a universal, a general form to light, inherent in all particulars the same genus.
