What Exists
What is this, really?
How to use this lens
- Name the phenomenon in one plain sentence.
- List parts — physical, informational, social.
- Ask what would break if people stopped believing it exists.
- Separate signal from container — the message vs the medium.
Mini-examples
- A dollar bill exists as paper, ink, and a shared ledger of trust.
- A meeting exists as calendar entries, people in a room, and an agenda in minds.
- A database row exists as magnetic domains and as a contract between services.
Curriculum bridge
Formal tools for “what exists” live in Information Theory (what is distinguishable?) and Probability Theory (what outcomes are in the sample space?).
