Wittgenstein once said:“The world is the totality of facts, not of things.” This statement provides us with a clear dividing line—the modes of existence can be divided into two forms: the existence of facts and the existence of things.

Existence of Facts: Storage of Time

The existence of facts is temporal; it unfolds continuously with the flow of time.

• Completeness: Across the whole span of time, all facts that have occurred are recorded. Even if contradictions exist among them, together they constitute the totality of time.
• Dynamic Nature: Time storage carries the generative process of existence. It is flowing and constantly renewing.

Existence of Things: Storage of Space

The existence of things is spatial; it is the static capture of facts at a certain moment.

• Consistency: At the same moment, the things that exist in space are determinate and compatible.
• Incompleteness: It is only a snapshot in the river of time and cannot present the complete process.

“Dasein”: The Interface of Time and Space

The core concept put forward by Heidegger in Being and Time—“Dasein”—precisely lies at the intersection of time and space. In that instant, the complete facts in time are solidified into consistent things in space.

“Dasein” is the critical point where facts transform into things, the moment when the unfolding of time is compressed into a spatial snapshot.

The Dual Structure of Existence

Through this distinction, we can see:

• Time Storage → bears the generativity and totality of existence
• Space Storage → bears the determinacy and visibility of existence
• Dasein → the interface connecting and transforming the two
  

Human existence is situated at the convergence of this dual structure: living both in the unfolding of time and in the certainty of space. “Dasein” is the critical instant of our being, the core where time and space intertwine.
