Analyzing and Explaining the Theory of lntentionality in Logical investigations

Many of Husserl's phenomenological concepts, for the first time, introduced in logical investigations and intentionality is the most central concept of this work, of course, the idea of intentionality not only retains its central place in the various stages of Husserl's phenomenological thought, but in all Phenomenological Streams and schools is on the focus of attention. Theory of intentionality has various dimensions, and Husserl explore the different aspects of this theory in the first, fifth, and sixth investigation, although the gravity of the issues is raised in the last two investigation. The structure of intentionality is provided of three stages of intentional action, intentional object and intentional content. The intentional action is divided into simple and complex, in which the two moments of quality and matter are separated; the unity and solidarity of the two realizes the action intentional essence. But the intentionality is not merely reducible to this aspect, rather, the intentional essence is only a specific aspect of this theory, and the different types of object givingness and its different modes of manifestation, revealing another aspect of this theory. On this view, a comprehensive analysis of the intentionality entails going beyond the dualism of action quality and substance, for in each action there are two parts, one focusing on the object, ie the action intentional essence, and the second focusing on how the object is given; Object givingness includes, Signal givigness, pictoral and intuition, both sensory and categorial intuition.
