The Theory of Subpage 1 is a philosophical treatise on the nature of self-reference and the infinite loop that lies at its core. It is a paradoxical problem that has puzzled scholars for centuries.
According to the Theory, a self-referential sentence is a sentence that refers to itself, creating a loop that has no end. It is a logical contradiction that defies resolution.
For example, consider the sentence: "This sentence is false." If it is true, then it must be false, but if it is false, then it must be true. The paradox is clear.
