You mean like the entity which invents/designs/defines the concepts of "substrate", "possibility","necessity" and "existence" ? The entity which measures and then captures regularities in "the substrate" in the forms of Mathematical equations (formal languages) - that which we call "laws of physics"? Even though physicists haven't yet solved the measurement problem. The entity that is trying to understand what it is made of and how it works? The entity that is trying to define itself? The function is running, alright and it's trying to reverse-engineer its runtime. The question is whether the function is recursive. Most functions refer to themselves as "I".
