Atheistic Propositions that are Self-defeating:
Based on a video by Christian philosopher Frank Turek.
A self-defeating proposition is a proposition that is self-contradictory; if it’s true then it’s false. So a self-defeating proposition violates the law of non-contradiction which is one of the fundamental laws of logic.
A few obvious examples could be if I write “I can’t write a word in English” or if I say “my parents never had kids”.
Let’s see how we can provide some easy responses to some common self-defeating atheistic propositions that are very popular in our so called modern world and which we as theists often come across in our preaching.
1. There is no truth <– is that proposition true?
2. You can’t know the truth <– do you know that proposition to be true?
3. All truth is relative <– is that a relative truth?
4. It’s true for you, but not for me <– is that true for everybody?
5. No one has the truth <– how do you have that truth?
6. Everything is meaningless <– what do you mean by that?
7. You ought not judge <– isn’t that a judgment?
8. You should doubt everything <– should I doubt that proposition?
9. There is no truth in religion, only in science <– is that a scientific truth? (no it can’t be proven in a lab. It’s a philosophical, metaphysical assumption).
See the video for more detailed explanations of the above self-defeating statements.
We might add these statements also:
10. You should think for yourself <– then I shoudn’t listen to you, right?
11. You shouldn’t force your beliefs on others <– then why do you force this belief on me?
Really enjoyed this forum post.
Another is: There are no absolutes. <- Oh, really? Are you speaking absolutely?
There is only relativity. <- Oh? So you're saying relativity is absolute?
