More Practice, and More Abstract Arguments

 

Analyzing and Evaluating Arguments

 

Most of the arguments we’ve considered so far had a relatively familiar and “concrete” subject: the choice of a major. Philosophical arguments, however, usually address more abstract and sticky material, like the existence of God.

 

For example, let’s take a look at the following conversation between five people, each of whom is offering an argument to support his or her opinion. As you read each argument, try to identify the ultimate conclusion and decide if the argument is good or bad. Click on the name of a participant to examine that person’s argument more closely.

 

Linda: “Sure God exists! After all, some people have recovered from very serious illnesses after being prayed for, and the only way this could happen is if God exists.”

 

Bill: “You’re right, Linda. Besides, the Bible is the word of God and God always tells the truth so everything the Bible says is true.  And the Bible says that God exists, so God must exist.”

 

Susan: “As far as I’m concerned, religion is just another kind of superstition. Think about it! Some distinguished scientists don’t believe in God. Consequently, God doesn’t exist.”

 

Mike: “Furthermore, when I was 8, I didn’t get the bicycle that I prayed for. God, if he existed, would have given me the bicycle. Therefore, God doesn’t exist.”

 

Leslie: “That’s right. God doesn’t exist. If God existed then there’d be evidence of his existence because if God existed, he’d want people to believe in him. But there isn’t any evidence that God exists. Besides, belief in God is nothing more than a form of mental illness, since there are similarities between religious experiences and schizophrenic hallucinations.”

 

The Bearing of Arguments on Ultimate Conclusions

 

After you’ve examined all of the arguments you want from this conversation, consider the comments of the following listeners.

 

Mary: “I like Linda’s point when she says that people recover from serious illnesses after being prayed for and that this could only happen if God existed. I think this is a really good argument for the existence of God!”

 

Can you conclude from this that Mary believes in God?

Rest the mouse here to find out.

 

George: “I can’t believe that Mike’s an atheist just because he didn’t the bike he prayed for. What a lousy argument against the existence of God!”

 

Can you conclude from this that George believes in God?

Pin the Tail on the Donkey

 

It’s also useful to be able to identify the part of an argument that’s targeted by an objection. I think of these as “Pin the Tail on the Donkey” exercises because you pin the objection on the diagram. I’ll present you with two arguments, followed by criticisms of the argument. For each criticism, see if you can identify the part of the argument (the premise or the inference) that it criticizes. You can check you answer by resting the mouse over the name of the person leveling the objection.

 

The Teleological Argument for God’s Existence: “God must exist. After all, natural objects are very well put together. (The human eye, for example, adjusts to let in the right amount of light for vision.) We know that many objects – like watches – are very well put together because intelligent beings created them. It’s reasonable to conclude, therefore, that natural objects have been created by an intelligent being. Therefore there must be a God.”

 

1. There must be a God.

2. Natural objects are very well put together.

3. We know that many objects – like watches – are very well put together because intelligent beings created them.

4. Natural objects have been created by an intelligent being.

Elliot: I don’t think that natural objects are very well put together. Plants and animals are breaking down all the time!

 

Francis: Sure, natural objects are put together well. And it’s true that objects like watches are very well put together because intelligent beings created them. But those are artifacts. It doesn’t follow from this that natural objects were created by an intelligent being.

 

Ann: Mightn’t natural objects have been created by an intelligent being other than God – really smart aliens, for example?

 

A Response to the Teleological Argument: “Evolution is the right explanation for why natural objects are vey well put together. Therefore, the teleological argument for God’s existence doesn’t work. But the teleological argument is the best argument we have for God’s existence and so no argument for God’s existence will be very good. Therefore we shouldn’t believe in God.”

 

1. We shouldn’t believe in God.

2. Evolution is the right explanation for for why natural objects are vey well put together.

3. The teleological argument for God’s existence doesn’t work.

4. The teleological argument is the best argument we have for God’s existence.

5. No argument for God’s existence will be very good..

Roberta: “I’m not so sure that evolution is correct. The fossil record is pretty weak in some areas.”

 

Zach: “I think that some versions of the teleological argument presuppose the truth of evolution. The point is why are various natural laws the way the are, the way that allows for evolution?”

 

Chris: “Aren’t other arguments for God’s existence better than the teleological argument?”

 

Sally: “I think we should believe in God on the basis of faith, not argument.”
