1. Philosophy of Universals: Do universals exist?
Universals are properties that multiple things share, like “redness” or “beauty.” Philosophers disagree on whether these exist on their own or just in our minds.
🔹 Plato’s Two-World Theory (Strong Realism)
• There are two realities:
1. World of Forms(Ideal World) – A perfect, unchanging place where universal concepts (like “Redness” or “Justice”) exist.
2. World of Particulars(Our World) – Physical objects (like red roses) imitate these perfect Forms.
• Example: A red rose is red because it participates in the perfect idea of “Redness.”
🔹 Aristotle’s Moderate Realism
• Universals exist, but only within things—not in a separate world.
• Example: “Redness” is real, but it only exists inside red objects like roses and trucks, not in some abstract realm.
🔹 Nominalism (Russell leans toward this)
• Universals don’t really exist—they are just names we use.
• Example: “Redness” is just a word we use to group similar things, not a real thing by itself.
2. Russell’s Argument for Universals
Russell believed universals must exist because:
1. Many things share the same property (e.g., a red rose and a red truck are both red).
2. If “redness” was just a name, how could two objects have the same color?
3. Universals must be independent of things, but they show up inside particular objects.
🛑 Objection (Nominalist Argument)
• Just because we call things “red” doesn’t mean there’s a real thing called “Redness.” It’s just a mental shortcut.
🔧 Russell’s Response
• If “redness” were just a name, we wouldn’t be able to recognize the same color in different objects. There must be something real linking them.
3. Theological Argument: Universals and God
• If universals exist on their own(Plato’s view), do things like morality and justice exist apart from God?
• If universals exist only inside things(Aristotle’s view), does that mean morality is based on God’s nature?
🛑 Challenge:
• If moral truths exist outside of God, does that mean God is not in control of them?
• If moral truths exist inside God, does that mean morality is just God’s preference?
4. Analogical vs. Non-Analogical Forms
• Analogical Meaning– A word’s meaning changes slightly depending on context but stays similar.
• Example: “God is good” vs. “This cake is good.” (Same word, but slightly different meaning.)
• Non-Analogical Meaning – A word always means the exact same thing.
• Example: “Redness” means the same thing whether in a rose or a truck.
5. Resemblance Theory: No Universals, Just Similarities
• This theory says universals don’t exist at all.
• Instead, we notice patterns and group things together in our minds.
• Example: A red rose and a red truck look similar, so we mentally group them under “redness,” but “redness” itself isn’t a real thing.
🛑 Objection:
• If universals don’t exist, how do we compare objects at all?
🔧 Response:
• Our minds create categories without needing real universals. We just recognize similarities.
Challenge Questions
1. Russell’s Proof Objection:
• If “redness” exists independently, where is it when no red objects exist?
2. Plato vs. Aristotle:
• How would Aristotle argue that “Redness” does not exist in a separate world?
3. Theological Challenge:
• If moral truths exist outside of God, does that limit God’s power? If they exist in God, does that make morality arbitrary?
4. Resemblance Theory Weakness:
• If resemblance alone explains universals, how do we recognize completely new colors we’ve never seen before?
