Husserl claimed that reduction is the true starting point of phenomenological research, but to figure out how this deed should actually be accomplished has turned out to be a very challenging task. In this study, I explicate how Husserl accomplished reduction during his series of lectures entitled The Idea of Phenomenology. He does not state it explicitly, but what actually happened on the last day of the lectures can be seen as consistent with his descriptions of reduction as an act. (...) Understood in this way, reduction is the model of how to do philosophy. The result of Husserl’s reduction is the correlation between appearance and “that which appears” or, to use Husserl’s later terminology, between noēsis and noēma. When this correlation is understood as an outcome of reduction and not as a result of an analysis, we, as readers of Husserl, will be in a better position to avoid natural attitude in our interpretations.
