Descartes hopes to minimize or remove the role of unreliable sense perception in the sciences. Descartes acknowledges that thinking includes doubt, understanding, affirmation, denial, will volitionrefusal, imagination, and senses. Yet I am a true thing and am truly existing; but what kind of thing?
Here lies the basis of an ethical endeavour. This sobering realization leads to Descartes' infamous efforts to refute the Evil Genius Doubt, by proving an all-pefect and therefore non-deceiving God.
I now know that even bodies are not strictly [proprie] perceived by the senses or the faculty of imagination but by the intellect alone, and that this perception derives not from their being touched or seen but from their being understood; and in view of this I know plainly that I can achieve an easier and more evident perception of my own mind than of anything else.
The conclusion — that I don't Know that I'm now awake — has widespread sceptical consequences. On needing reasons for doubt contrary to direct voluntarismsee Newman Even so, I regularly speak in terms of the evil genius following Descartes' leadas a kind of mnemonic for the more general doubt about our cognitive nature.
Perhaps there may be some who would prefer to deny the existence of so powerful a God rather than believe that everything else is uncertain.
Descartes thinks that doubt will move the inquirer toward the elimination of error and, accordingly, certainty will be given to knowledge.
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 debated. Descartes locates himself firmly in the rationalist camp, as opposed to the empiricism of Aristotle or his contemporary, John Locke.
This line of questioning again the details of that argument are not necessary to this discussion led him to draw this conclusion: For the Second Meditation passage is the one place of his various published treatments where Descartes explicitly details a line of inferential reflection leading up to the conclusion that I am, I exist.
On one plausible line of reply, Descartes does not yet intend to be establishing the metaphysical result; rather, the initial intended result is merely epistemic. This indefeasibility requirement implies more than mere stability.
The discovery of Euclid's first principles some of them, at any rate is comparatively unproblematic: But in order to remove even this slight reason for doubt, as soon as the opportunity arises I must examine whether there is a God, and, if there is, whether he can be a deceiver.
According to Descartes, this idea of a supremely intelligent and supremely powerful being, who created everything that exists, can not and does not come from within him who is imperfect. On what basis, then, do I conclude that the productive processes are different — that external objects play more of a role in waking than in dreaming?
Instead, he attacked what he considered the very foundation: Much ado has been made about whether dreaming arguments are self-refuting. Plato's allegory of the cave portrays this rationalist theme in terms of epistemically distinct worlds: His point is to demonstrate that the senses can be deceived.His greatness is found in his contribution to the thinking process itself in the form of analysis and synthesis, as Spinoza suggests, (Spinoza, p.
3) and his methodological or deductive process of discovering knowledge. Descartes search for knowledge starts with a claim of doubt. How do we define it? Man’s struggle with the definition of knowledge and how we define existence is a driving force behind the questions asked by philosophers throughout history.
From Plato to Descartes, from Aristotle to Kant, the understanding of existence became nearly an obsession of the great philosophical minds.

On a quite different reading of this passage, Descartes is clarifying that the analysis of knowledge is neutral not about truth, but about absolute truth: he's conveying that the truth condition requisite to knowledge involves truth as coherence.
On Descartes' analysis, there are three possible options for the kind of external thing causing sensations: God; material/corporeal substance; some other created substance; That is, the cause is either infinite substance (God), or finite substance; and if finite, then either corporeal, or something else.
