Criterion for reality: something that can hit back exists. But also Dr. Johnson did not directly hit the stone. He just hit some nerves, and so on.

Def Reality/Deutsch: if a quantity is complex and autonomous according to the simplest explanation, then it is real.

Theory: the more fundamental a theory is, the more comprehensive are the observations that play a role in it. Physical reality is therefore self-similar in several ways.

After all, not everything that is real must be easy to identify.

Simulation: A reality simulator indirectly conveys both internal and external experiences to the recipient, but it cannot be programmed to simulate a particular internal experience. Roulette example and tennis example: the framework conditions are defined here, the course of the game must be open, which means that the abstract laws themselves and not only their predictive power can be simulated in virtual reality.

Life = simulation: both are embodiments of theories about the environment;
Something that only exists in the laws of classical physics does not exist in reality.
Real hurricanes and butterflies obey the laws of quantum theory, not those of classical mechanics!

Plato's apparent refutation that the methods of natural science could lead to mathematical truth: we cannot know anything about perfect circles because we only have access to imperfect circles.
DeutschVsPlato: then we can also only build inaccurate tool machines, because the first ones are built with inaccurate tools. So there would be no possibility of self-correction.
