It’s the same thing with “absolute truth.”
It’s similar to one saying, “there is no such thing as words,” but using “words” in order to make the argument. The very act of using words destroys that argument that “there is no such thing as words.” It’s the same thing with “absolute truth.”
The very statement, “absolute truth does not exist” is an absolute truth statement. (Please re-read that if it makes your head spin a little.)
When someone says, “there is no absolute truth,” they are making use of an absolute truth. They are saying, “I know absolutely that it is true that there is no absolute truth.” Do you see the contradiction?
More simply, if someone says, “There is no absolute truth,” we could counter with, “Do you know that to be true absolutely?”
Honestly, I’m convinced that deep down, all people know that absolute truth exists. Because we live that way. Sometimes people claim to not believe it, but they don’t live that way. I’ll illustrate.
I most often have people deny absolute truth on College Campuses. When a student tells me confidently that there is no absolute truth and we can’t know anything for certain, I ask them if they know “there is no absolute truth” for certain?
I also point out that their lifestyle and actions betray their claim. I say something like, “If I punched you in the stomach and stole your iPhone, what would you say?”
And, every time, they say that my actions were “wrong.”
I ask, “Could I successfully make the case that it’s wrong for them, but right for me?”
No, we all know it’s wrong to punch someone in the stomach and steal their iPhone. It’s wrong absolutely. And when the student agrees with me, they’re demonstrating that their own argument against absolute truth is invalid.
