The reason Descartes says to disbelieve everything is because most of the beliefs he used to hold were false, and Descartes began doubting everything after this finding. The reason being is because when he believed those things he didn't realise they were false. Which in turn got him thinking that, the ideas he still believed might false and he just doesn’t know it yet. The only true way to figure out what was true and what was not was for Rene was to disbelieve everything, temporarily.* An analogy used by Rene was if you had a crate full of apples and were concerned some might be rotten. Since the rot could spread and ruin the apples the only logical thing to do is to dump them all, and inspect them by hand and return only the fresh apples.* …show more content…
Then he’d know he would only be believing true things. Rene used three main beliefs to see what was true and not, they are as listed: Empirical beliefs, Local Doubts, and Global doubts. Empirical beliefs are things we know directly because of our senses. Rene doubted that if we could see it, hear it, taste it, and feel it then it must be real. The reason so is because our senses fail us all the time. For example if you rush to catch up to friend only to realise your eyes have played a trick on you and you’ve just tapped the arm of a total stranger. Another one is that food can taste wrong of different when you’re sick. There are tons of more ways you senses give you false information. Bringing it back to Skeptical Rene, after he realised his senses has bamboozled him, he disbelieved his senses temporarily as well, until they could be proven true indefinitely. I.E. with vivid dreams, dream ceptions, and the most common, Déja vù. Although not everyone experiences with these cases but when we are, for instance dreaming, we don’t know that we’re dreaming while it’s happening, how could he or even ourselves be sure we’re not dreaming right now.
