Where are we? Simulation Theory/Cartesian philosophy

I’ve heard that simulation theory goes back centuries to Descartes’ time (16th/ 17th century), possibly earlier.

Are we living inside a simulation?


Simulation Hypothesis


The simulation hypothesis or simulation theory proposes that all of reality, including the Earth and the universe, is in fact an artificial simulation, most likely a computer simulation. Some versions rely on the development of a simulated reality, a proposed technology that would seem realistic enough to convince its inhabitants the simulation was real. The hypothesis has been a central plot device of many science fiction stories and films.


Simulation Theory/Cartesian philosophy and the Evil Demon

(“a complete illusion of an external world”)


René Descartes

The evil demon, also known as malicious demon[1] and evil genius,[2] is a concept in Cartesian philosophy. In the first of his 1641 Meditations on First Philosophy, Descartes imagines that an evil demon, of “utmost power and cunning has employed all his energies in order to deceive me.” This evil demon is imagined to present a complete illusion of an external world, so that Descartes can say, “I shall think that the sky, the air, the earth, colours, shapes, sounds and all external things are merely the delusions of dreams which he has devised to ensnare my judgement. I shall consider myself as not having hands or eyes, or flesh, or blood or senses, but as falsely believing that I have all these things.”
