"Have you ever had a dream, Neo, that you were so sure was real? What if you were unable to wake from that dream? How would you know the difference between the dream world and the real world?- .
Descartes himself concludes on the basis of his dream argument that sense experience is an unreliable justification mechanism, and so suspends all beliefs he has formed on the basis of sensory evidence. .
It is up to you now the reader/listener to take all this and ask your self the question of do you believe in this reality or is there other one, where you exists in a bubble of ooze and where you are nothing more then a coppertop for machines and your mind locked in a prison in a computer controlled world your mind was placed in. Or are you in a reality of someone else's mind, so what is real?.
Reality according to Bruno Latour:.
There is no natural situation on earth in which someone could be asked this strangest of all questions: "Do you believe in reality?- To ask such a question one has to become so distant from reality that the fear of losing it entirely becomes plausible - and this fear itself has an intellectual history that should at least be sketched. Without this detour we would never be able to fathom the extent of the misunderstanding between his colleague and him (conversation he had with a psychologist friend in regards to reality.). .
He recalls that his colleague's question is not so new one. His compatriot Descartes had raised it against himself when asking how an isolated mind could be absolutely as opposed to relatively sure of anything about the outside world. Of course he framed his question in a way that made it impossible to give the only reasonable answer, which we in the science studies have slowly rediscovered three centuries later: that we are relatively sure of many of the things with which we are daily engaged through the practice of our laboratories. By Descartes's time this sturdy relativism, based on the number of relations established with the world, was already in the past, a once-passable path now lost in the thicket of brambles.
