>>12410531>How can you even trust "reality"?You can't. You make reasonable assumptions based on your observations.
If everything is real and your flawed perception brings you somewhat "close" to reality, but never actually there, then you do the best you can with available data, work on theories and assumptions, knowing that you'll never be 100% sure or correct. Falsification is a powerful tool in this context.
If nothing is real then everything is a game, the universe is a sandbox experience and you can toy around with your existence and life all you want. You'll know that at least that thing that is EXPERIENCING that fantasy world exists.
That is what Descartes truly meant by "I think, therefore I am". It's often interpreted as a homage to the superiority of the human mind or whatever. What he was really doing, was asking himself what he could possibly think of that he can truly be sure of above all else, that is truly undeniable. The statement "I think, therefore I am" means that that is the ONLY thing he can possibly ever state or say that he can be truly sure of. Whatever is experiencing reality, or a dream, or a fantasy, or a simulation, the matrix, whatever, that thing exists to experience it. Beyond that you can't ever truly know anything.
