Whether he is aware of it or not, every human being dwells in tradition and history. Human memory is this constant dwelling in tradition. It constitutes that fundamental human characteristic of historicity.

If man did not exist as a world-spanning receptive realm of perception, if he were not engaged in this capacity, nothing at all could exist. 'Being,' in its traditional usage, means 'presence' and 'persistence.' To achieve presence, and thereby being, an entity requires some sort of open realm in which presence and persistence can take place. Thus an open realm of perception like that of human existence is the one being that makes being possible.

Death is an unsurpassable limit of human existence... We discover the relationship which is the basis for all feelings of reverence, fear, awe, wonder, sorrow, and deference in the face of something greater and more powerful... Only such a being-unto-death can guarantee the precondition that the Da-sein be able to free itself from its absorption in, its submission and surrender of itself to the things and relationships of everyday living and to return to itself.

The prevailing attunement is at any given time the condition of our openness for perceiving and dealing with what we encounter; the pitch at which our existence is vibrating. What we call moods, feelings, affects, emotions, and states are the concrete modes in which the possibilities for being open are fulfilled. They are at the same time the modes in which this perceptive openness can be narrowed, distorted, or closed off.

A new vision and understanding of something demands a new way of talking about it, for the old terminology gets in the way of this effort. Stubbornly entrenched behind the words coined by a particular conceptual orientation are its secrete prejudices. Any attempt to open out an adequately human vista onto the phenomena of undisturbed existence must include a critique of the most important idea of traditional biology, physiology, and psychology.

The borders of my bodyhood coincide with those of my openness to the world. They are in fact at any given time identical, though they are always changing with the fluid expansion and contraction of my relationships to the world.
