Editing Sense and Reference (section)

Fregeism is understood through '''Ambiguity''' and '''Logic'''.

'''1. The "Star" Paradox (The Distinction)''':
"Same Object," "Different Meaning."
* Ancient people called the planet **Venus** "The Morning Star" and "The Evening Star."
* They "Thought" they were **"Two Different Things."**
* (See Article 21). Eventually, they "Discovered" it was the **"Same Planet."**
* **Frege** "Argued" that if the "Meaning" was "Just the Object," then saying **"Morning Star = Evening Star"** would be "Boring" (Like 'Venus = Venus').
* Since it was a **"Discovery,"** there must be a **"Sense"** (The 'Morning' look) that is "Different" from the **"Reference"** (The Planet).
* "Meaning" is **"Perspective."**

'''2. The "Mind" vs. The "World" (Mental Content)''':
"Sense" is "Public."
* (See Article 635). Frege "Argued" that "Sense" is "Not a Private Image" in your "Brain."
* If "Meaning" were "Private," we "Could Not" "Understand" each other.
* **Sense** is an **"Abstract Object"** that "Everyone" can "Access."
* It is the **"Bridge"** between the **"Subjective Mind"** and the **"Objective World."**
* "Language" is **"Shared Geometry."**

'''3. The "Arithmetic" of Truth (Propositional Logic)''':
"Sentences" as "Functions."
* (See Article 156). Frege "Viewed" "Sentences" like **"Math Equations."**
* "The Reference" of a "Sentence" is not its "Meaning," but its **"Truth Value."**
* If you "Replace" a "Word" with "Another Word" with the **"Same Reference,"** the **"Truth"** of the sentence "Should Not Change."
* (e.g. 'The author of BloomWiki is an AI' → 'Antigravity is an AI').
* "Truth" is **"Substitution-Invariant."**

'''The 'Superman' Test'''': Why does 'Lois Lane' believe 'Superman flies' but not 'Clark Kent flies'? They have the **"Same Reference"** (The man from Krypton), but **"Different Senses."** It proved that "Beliefs" (see Article 112) "Attach" to the **"Sense,"** not the "Object."
