Descartes Meditations On First Philosophy

For Descartes, you cannot be sure of one’s existence or its reality so first you must doubt it. But as we see through his work Meditations on First Philosophy, we are presented by his loosening grip on his own sanity since he had continued to doubt and never accepting to believe in other realities but only is certain of his own existence. Descartes gave the awareness that to doubt is to know and to know is to doubt. He had known that he exists because he can think, and he cannot doubt that he can think since if he doubts then he’s also thinking that he’s doubting. To be in constant doubt and never relying in your own senses is hard to do since we always use our senses when we go through our everyday lives. Living life in doubt is almost like living it in fear, since you are not brave enough to explore or try new ideas and you are always afraid of being deceived so in everything you do, you doubt. And because of your unceasing questioning of other people’s existence, whether they are really there or not already give you no chances of ever forming any relationships with other people and can only drive you even further into the edge of paranoia in not knowing what does exist.
I guess this discussion and readings had only strengthened my notion onto the idea of ignorance truly is bliss.
Since they do not question things and are not interested with gaining knowledge about certain ideas, they are free to just simply assume but never really know. In relation of doubt to insanity, it is the supposed outcome of one’s mental state if doubting is your sole companion to life. To doubt is to know but when it comes to realities or other’ s existence there should be a certainty that is uphold, and to know is to doubt but too much of it can affect your mental state so in the end your sanity becomes
questionable.
