The essence of Husserl’s intentionality does not lie in any object, but in the marginal horizon presupposed by intentional acts. This characteristic can be seen whether on the level of intensional act or that of noema (intentional object). The reason is that all intentional act and noema come from the stream of internal time consciousness, and thus have Zeithof (time halo or time aureole), while the original meaning constituted by such a halo is prior to the object they are concretized into, and the noema that contains the possibility of meaning will also be intuited together with the perceived adumbration. Using Husserl’s idea that the meaning of non-objectification is prior to the object, Scheler breaks through Husserl’s dogma that the presentation of an object must precede the giving of value to the object, and thus puts forward the new train of thought that the feeling of value is not later than the objectification, or even prior to it. Heidegger deepens and expands the sense of the marginal horizon, revealing in all human behaviors and world presentation such an ontological structure, that is, halo-like meaning or the act of Being itself precedes objects and beings created by the separation of subject and object. Maurice Merleau-Ponty states that the body field is prior to the separation of body and mind, and the body’s perception of external phenomena is first carried out in the manner of field rather than definite objects, therefore, it must have the original ambiguity and be realized in the form of body schema instead of a causal chain. So, the philosophical vitality of phenomenology does not significantly lie in the explanation of the levels and functions of intentional objects, but in the construction premise of such objects, namely, the spatio-temporal halo manifested as marginal horizon, time stream, and the displaying of existential vista.
