Abstract: “The phenomenology of mind and nature” contains two aspects. One is that it takes consciousness and its essence as its study object; in other words, it is concerned with “mind and nature” in content. And the other is that it takes phenomenological structural descriptions and genetic expositions as its basic approaches. That is to say, it is concerned with “phenomenological” in methodology. The main task of mind-nature phenomenology aims at grasping the essential connection between consciousness’ essential and other factors through reflections and ideation. Such an essential connection means a kind of connection of essential factors in their static structure, and also their connections in the genetic history. Correspondingly, the method of horizontal or vertical essential intuition is employed.

Key words: consciousness, essence, phenomenology, vertical and horizontal intentionality, vertical and horizontal eidetic intuition
