Who Is Rene Descartesian Doubt?

One might think it to be safe to assume the fact that they’re reading this text right now, but is it really that clear and easy? How can one really know for sure that they aren’t sleeping and simply dreaming about reading this text? René Descartes argued that you couldn’t, but he wasn’t satisfied with that answer and rejected the idea of former skeptics that we can’t possibly know anything for certain. He made it his goal to find something we couldn’t doubt, something indubitable. René Descartes is a famous French mathematician, scientist and philosopher from the 17th century, often called “the Father of Modern Philosophy”, his philosophical work is often closely connected to his scientific work since he saw philosophy as a foundation to science.
To begin with, Cartesian doubt is a form of skepticism made famous by René Descartes in the 17th century, it is a form of skepticism that deals with doubting one’s beliefs in order to determine whether they are true or not. At the time when Descartes lived, Aristotle’s teaching was widely followed by scholars and was believed to be legitimate. Descartes disagreed with Aristotle theories and thought it was time for a new way of thinking. Furthermore, it was also around the time when science became more prominent, Descartes thought this new science needed a strong foundation and that foundation was
Cartesian Dualism is Descartes’ thesis that the mind and body are distinct and that there is actually two kind of substances: Matter and mind. Matter, being spatially extended, composed of things subject to the laws of physics such as: rocks, flesh, planets, etc. Mind, whose essence is thinking, which isn’t subject to the laws of physics and is made up of human consciousness and thoughts. As has been noted, Descartes’ foundation to philosophy is that the only thing he knows for certain is that he exists as a thinking thing, knowing that, Descartes also claims that he since he can doubt that his body exist and that he cannot doubt that he exists then that must mean that they are two different things. Similar to Leibniz’s Law something is only identical to something else if they have the same property, if they don’t then they are different, since the existence of the body can be doubted and the existence of the mind cannot be doubted they must be separate things and have different properties: Matter made of resextensa and mind of rescognita. The nature of the mind is being a thinking, non-extended thing while the body is an extended, non-thinking thing that means that they can both exist alone and are completely different. The body is like a machine while the mind is the one stepping in to control the body when needed.
