There exists a militant atheist website at the following URL: godisimaginary.com. The home page makes some of the following claims:
- Billions of people attend millions of churches around the world to worship God. Yet the God they worship is completely imaginary. Their belief represents a delusion.
- It is easy to prove that God is imaginary. Start at the beginning with Proof #1…
This site claims to present 50 proofs that God doesn’t exist. I will attempt to address all 50 of these “proofs” one by one. But first, let us define some terms.
- A proof is a series of propositions in a logical formula used to establish the truth of the argument.
- An argument is a set of statements used in an attempt to establish a fact. Arguments require at least 1 premise and a conclusion. An argument is not a statement of fact or a series of statements of fact. For example, this is not an argument:
- The sky is blue.
- My shoes are blue.
- I like my shoes because they remind me of the sky.
This is an argument:
- Premise: All computer programmers are geeks.
- Premise: I am a computer programmer.
- Conclusion: Therefore, I am a geek.
- A premise is a statement that supports a conclusion.
- A conclusion is a deducted inference that must be true if the argument is sound.
- A sound argument is an argument that is valid and all of its premises are true.
- An argument is valid if and only if it is impossible for the premises to be true and the conclusion to be false. In other words, if all of the premises are true and the conclusion is false, the argument is invalid. Observe the following invalid argument:
- All computer programmers drink decaffeinated coffee.
- I am a computer programmer.
- Therefore, I drink decaffeinated coffee.
While at first glance this argument looks fine, it is in fact the case that I am a computer programmer and drink strongly caffeinated coffee. Therefore, the argument is invalid. The first premise is false.
As I systematically analyze the arguments (or non-arguments) made by the authors of the site linked above, I will be looking for valid and sound arguments as well as formal and informal logical fallacies.
