Every now and then, a conversation with a friend transforms into a debate about the existence of **absolute truth**.

I think absolute truth exists, but not many ideas or statements can be labeled as 'absolute truth'. To be more specific, I think that absolute truth can only be applied to **some** *mathematical* concepts.

**Q: What is absolute truth?**

A: Absolute truth is something that is true regardless of the context (this definition is subject to change).

- For example we can say that "parallel lines never intersect", but this is only true in the context of Euclidian geometry. Even though it is a math-thing, it is not an absolute truth.
- Another example is "1+1=2", it is a bit more difficult to counter. The statement is true if '+' means "add two numbers", but it could also mean "concatenate", so the result would be "11".
- Try to prove that "1+1=2" without first defining '2' as the next integer after '1'; if you can't, then why not "1+1=3"? (for very large values of '1' :-)
