Welcome to Philosophy of Religion!
Hi there! Welcome to your study notes for Paper 1: Philosophy of Religion. In this chapter, "Philosophical issues and questions," we are going to look at the three most famous arguments for the existence of God. Think of yourself as a juror in a court case—you’ll be looking at the evidence, listening to the experts, and deciding which arguments "hold water" and which ones leak!
Don’t worry if some of the words look a bit "philosophical" at first. We will break them down into bite-sized pieces. Let’s dive in!
1.1 The Design Argument (Teleological)
The Design Argument looks at the world around us and says, "Look how complex and organized everything is! This can't be an accident; someone must have designed it."
Key Terms to Know:
1. Inductive Reasoning: An argument where the conclusion is likely to be true, but not 100% certain. It’s based on probability.
2. A Posteriori: Arguments based on experience and looking at the world (the evidence) first.
3. Analogy: Comparing two things to show they are similar.
William Paley and the Watchmaker
Imagine you are walking across a field and you find a pocket watch. You notice its gears, springs, and tiny movements all working together for a purpose (telling time). You wouldn't think it just "appeared" there by chance. You would conclude it had a designer. Paley argues that the universe is much more complex than a watch—just look at the human eye or the seasons—so the universe must have a "Grand Designer" (God).
Types of Order
Paley talks about two types of "Regularity":
- Regularity of Co-presence: How parts work together at the same time (like the parts of an eye).
- Regularity of Succession: How things follow a pattern over time (like the planets orbiting the sun).
Did you know?
The Anthropic Principle suggests the universe is "fine-tuned" for human life. If the gravity of the Earth was just a tiny bit stronger or weaker, we wouldn't be here. It’s like a radio dial being set exactly to the right station!
David Hume’s Challenges
Hume was a skeptic who pointed out some flaws:
- A Flawed World: If the world has "design flaws" (like diseases or earthquakes), does that mean the designer is "flawed" or a trainee?
- The Vegetable Analogy: Why compare the world to a machine (a watch)? Maybe the world is more like a vegetable that grows on its own.
- Too Many Designers: A watch might be made by a team. Why assume there is only one God?
Quick Review: The Design Argument
Pros: It’s easy to understand and based on things we can see.
Cons: Evolution (Darwin) provides a natural explanation for design without needing a God. Deism suggests a designer might have started the world and then left it alone.
Key Takeaway: The Design Argument is a posteriori and inductive; it uses the complexity of the world to argue that God is the most probable designer.
1.2 The Cosmological Argument
While the Design Argument asks "Who designed this?", the Cosmological Argument asks "Where did this all come from?"
Thomas Aquinas and the Three Ways
Aquinas used a posteriori reasoning to argue that everything needs a starting point:
1. Movement (The Unmoved Mover): Everything is moving. Something must have given the first "push."
2. Cause (The Uncaused Cause): Nothing causes itself. There must be a "First Cause" that started the chain.
3. Contingency: Most things are contingent (they depend on something else to exist). But if everything was contingent, once upon a time there would have been nothing. There must be one Necessary Being (God) who has always existed and doesn't depend on anyone.
The Kalam Version
This version focuses on the beginning of the universe. The logic is simple:
1. Everything that begins to exist has a cause.
2. The universe began to exist.
3. Therefore, the universe has a cause (God).
Challenges: Hume and Kant
- Infinite Regress: Why can't the chain of causes just go back forever? Critics ask, "If God caused the world, who caused God?"
- The Brute Fact: Bertrand Russell famously said the universe is just a "brute fact"—it's just there, and it doesn't need an explanation.
- Fallacy of Composition: Just because every human has a mother doesn't mean the whole human race has one single mother. Immanuel Kant argued we can't apply our "cause and effect" rules to things outside the universe.
Memory Aid: The "First Domino"
Think of a row of dominoes. They can't fall unless someone pushes the first one. The Cosmological Argument says God is that First Cause who tipped the first domino.
Key Takeaway: This argument claims the universe cannot be an infinite regress; it needs a necessary being to explain why there is something rather than nothing.
1.3 The Ontological Argument
This one is different! It doesn’t look at evidence in the world. Instead, it looks at the definition of God. It's like a math problem where the answer is hidden in the question.
Key Terms to Know:
1. Deductive Reasoning: If the premises are true, the conclusion must be true. It's 100% certain logic.
2. A Priori: Arguments based on logic and definitions, not experience.
3. Analytic Proposition: A statement that is true by definition (like "A triangle has three sides").
St Anselm’s Definition
Anselm defined God as: "That than which nothing greater can be conceived."
He argued:
- It is greater to exist in reality than just in the mind.
- If God is the "greatest possible being," He must exist in reality, otherwise He wouldn't be the greatest!
Necessary Existence and Aseity
God has Necessary Existence, meaning He cannot not exist. Aseity is a fancy word meaning God is self-existent—He doesn't need anything else to keep Him going.
Bertrand Russell’s Challenge
Russell argued that existence is not a predicate (a description).
Analogy: Imagine I describe a "perfect burger." I say it’s juicy, has cheese, and it exists. Adding "it exists" doesn't actually describe the burger; it just tells you if there is one in the shop! Russell argues you can't "define" something into existence.
Common Mistakes to Avoid:
Do not confuse a priori with a posteriori!
- Design/Cosmological = Look at the world (A Posteriori).
- Ontological = Look at the dictionary definition (A Priori).
Quick Review: The Ontological Argument
Pros: If you accept the definition of God, the logic is very strong.
Cons: Most people find it hard to believe you can prove God exists just by thinking about Him.
Key Takeaway: The Ontological Argument is a priori and deductive. It tries to prove that "God exists" is an analytic proposition—true by its own definition.
Final Study Tip!
When you are writing an essay on these, always remember to evaluate. Don't just list what Paley or Aquinas said. Ask yourself: "Is this argument persuasive to a modern scientist? Does David Hume’s criticism totally destroy the argument, or is there a way for a believer to answer back?"
You've got this! Philosophy is all about asking the big questions. Keep questioning!
