"Stolen Concept

Using what you are trying to disprove. That is, requiring the truth of something for your proof that it is false. For example, using science to show that science is wrong. Or, arguing that you do not exist, when your existence is clearly required for you to be making the argument."

You are trying to disprove I, by saying "I...", refering to you, your body, your experience of you, and then saying "do not exist", meaning you could have never made the statment. Like the grandfather paradox in time travel theory.
