Physical objects for descartes were defined by extension the entire universe comprised of time corpuscles i know my mind more easily than i know my body: i perceive with certainty that i exist as a thinking and unextended thing 3 i perceive with (virtual) certainty that my body, or any body for that. Meditations on first philosophy is a seminal work of philosophy by the french philosopher rené descartes it was first published in latin in 1641, with the french translation published a few years later. René descartes (1596 - 1650) was a french philosopher, mathematician, scientist and writer of the age of reasonhe has been called the father of modern philosophy, and much of subsequent western philosophy can be seen as a response to his writings he is responsible for one of the best-known quotations in philosophy: cogito, ergo sum (i think, therefore i am. Descartes arguably shifted the authoritative guarantor of truth from god to humanity (even though descartes himself claimed he received his visions from god)—while the traditional concept of truth implies an external authority, certainty instead relies on the judgment of the individual.
In the first meditation, descartes reflects on the number of falsehoods he has believed to be true during his life and subsequently the faultiness of the body of knowledge he has come to have. The next step in the pursuit of knowledge, then, is to prove that god does indeed exist descartes's starting point for such a proof is the principle that the cause of any idea must have at least as much reality as the content of the idea itself but since my idea of god has an absolutely unlimited. Descartes and the method of doubt the project: descartes stated that, if we are to get at truth—if we are to build up something firm and lasting—then we need to start from scratch, clearing away all of our previously held beliefs—anything that is doubtable—and build from the ground up.
 to say that he is essentially a mind and not a body is to say that his mind is part of his essence: if his mind ceased to exist, he would cease to exist, but he could exist without his body, so it is not part of his essence descartes also argues in med 2 that his knowledge of his mind through non-sensory means is also the best way to know. Descartes' demon a dialogical analysis of meditations on first philosophy alex gillespie university of stirling abstract descartes argued that the existence of reflective thought should be the first principle of philosophy because it is indubitable. He comes to the conclusion that he can know one thing for certain he exists, because he has the ability to question whether he exists as he puts it: i think, therefore i am (cogito, ergo sum). Descartes and the method of doubt doubt and certainty descartes argues that he can know whatever is ‘clear and distinct’ this is he is not dreaming, and that a physical world, including his body, really does exist and that he can trust his senses the answers to all these doubts, it turns out, is that god. This is what is known as the “cartesian circle,” because descartes’ reasoning seems to go in a circle in that he needs god’s existence for the absolute certainty of the earlier truths and yet he needs the absolute certainty of these earlier truths to demonstrate god’s existence with absolute certainty.
In the end, though, descartes succeeds in doubting his senses by recalling dreams he's had where he's been wrongly convinced that he was awake because such errors are possible, descartes thinks, he has adequate grounds to doubt beliefs formed through his senses. René descartes: discourse on method (1637) november 4, 2016 elizabethwasson rené descartes, the celebrated mathematician and physicist, is also often considered a founder of modern philosophy, as he sought new ways to move beyond medieval aristoteleanism and justify the science of his day. Descartes needs to be certain of some things (other than i exist) before he can prove the existence of god but in order to have this certainty, he must already know that god exists he is caught in a vicious circle. In sum, in considering descartes' answer to how we know, we can distinguish classes of knowledge that differ as regards the degree of certainty one may expect to achieve metaphysical first principles as known by the intellect acting alone should attain absolute certainty. Descartes and the existence of god once descartes has realized that he can know with certainty that “i exist” is true, he continues to build on his foundation of truths the truth about the nature of god, proof of god’s existence, and the nature of corporeal objects are considered, among others, after descartes proves his existence.
In meditation v, descartes argued that he can know that clear and distinct ideas are true and in meditation vi, he expresses this as ‘i know that all the things i conceive clearly and distinctly can be produced by god precisely as i conceive them’ (156. Some notes on descartes' discourse, part four i a brief outline of the discourse: in part one, descartes told of his life-long desire for learning, in particular a desire to gain clear and steady knowledge of everything that is useful in life that is, he wanted to learn not only information and ideas and opinions, but mainly things that were true and useful. But we also seem to know they exist from the faculty of imagination, which seems to be an application of the knowing faculty to a body intimately present to it -- hence, a body that exists so he can make mistakes about what nature teaches (sugarûcoated poison) as is the case with those actions that occur when one is awake i can. Descartes is a renowned name that is recognized by many as the father of current philosophy he was also an accomplished mathematician and meta-physician.
Certainty and doubt dualism the existence ofgod descartes lies more in the problems he identified and tried to answer, than in the third and final chapter provides a critical analysis of descartes and his philosophy through the topics it touches upon here, i have tried to give.

Descartes' meditations descartes' work entitled meditations, is a work on metaphysics in which descartes hopes to achieve absolute certainty about three issues: the soul as a thinking thing distinct from or without a body, the belief that god exists, and the belief that the external world exists. Because descartes concluded that he definitely existed, he also concluded that there exists at least one existential truth which we can claim to know: that we, as individual subjects, exist as thinking beings.
Meditations on first philosophy in which the existence of god and the immortality of the soul are demonstrated (latin: meditationes de prima philosophia, in qua dei existentia et animæ immortalitas demonstratur) is a philosophical treatise by rené descartes first published in latin in 1641. First, the solution runs contrary to descartes' no atheistic knowledge thesis: since the continuity test (on the naturalistic reading of it) does not invoke god, it thus appears, as hobbes notes, “that someone can know he is awake without knowledge of the true god” (at 7:196.
