I feel special to know your first activity was on here haha. Yes, exactly. How can we know that everything we think we know is in fact true? Or real? The Cartesian Method is very interesting but I think it has its flaws. Descartes says he thinks therefore he knows he exists but how can we know his thoughts are real? How can we prove what we're thinking is true? I remember he mentioned something about our reality could be manipulated by an unknown entity well our thoughts could be manipulated by that same unknown entity. So many questions yet so little answers.
I agree, and I don't think anyone has found the answers to these questions. What other philosopher tried to explain if what we're living is in fatc real? Found out about anyone interesting like Descartes?
