In this one brief text, Descartes turns many Aristotelian doctrines upside down and frames many of the questions that are still being debated in philosophy today. Among other things, Descartes breaks down the Aristotelian notion that all knowledge comes via the senses and that mental states must in some way resemble what they are about. In so doing, he develops an entirely new conception of mind, matter, ideas, and a great deal else besides.
We might understand the philosophical outlook that Descartes develops to be marked and defined by the skepticism he employs in the First Meditation. He begins by asking how he can be certain of anything and then develops all sorts of inventive and outlandish reasons as to why he ought to mistrust his senses. Philosophy ever since has been marked a constant skepticism toward knowledge claims, and the very question of how we can come to know anything with certainty has been much …show more content…

Skepticism and mind-body dualism have combined to create an understanding of the human mind as being locked away inside a body and separated off from the world. How this mind can come to know anything at all about the world is a mystery, and the certainty of this knowledge is sharply questioned. This conception of mind is so natural to us that it is sometimes difficult to understand that the pre- Cartesian world had a far less skeptical outlook toward knowledge and sensory
