Claim 5 of 8 · Case 05 · Relativism
The statement that all truth is relative is itself an absolute claim, so relativism undercuts itself before the conversation starts.
One claim from the free evidence repository at apologetics.pro.
If someone says there is no objective truth, only what is true for each person, ask whether that statement is objectively true. If it is, then there is at least one objective truth and relativism is false. If it is only true for them, then it is just their preference and gives no one else a reason to accept it. The same trap catches the moral version: there are no moral absolutes is stated as an absolute. This is not a word game. It shows that relativism cannot be stated without borrowing the very thing it denies.

The self-referential problem
This keeps the point precise. The argument is not that relativism leads to bad results, though it does, but that it cannot even be asserted coherently, which is a cleaner and stronger objection.
