Explain how descartes developed anselm's argument that god's existence is necessary firstly, if we briefly look at anselm and his ontological argument, which appears to be a priori proof of god's existence. He developed several arguments to illustrate this point in the dream argument, descartes argues that he often dreams of things that seem real to him while he is asleep in one dream, he sits by a fire in his room, and it seems he can feel the warmth of the fire, just as he feels it in his waking life, even though there is no fire. An ontological argument is one that attempts to prove the existence of god using reason and intuition alone in his book, meditations, descartes provides his own argument for god's existence and was the first person to do so since anselm of canterbury, due to st thomas aquinas' critique.
Descartes' argument this argument was built of of anselm's argument this philosopher argued that the idea of a perfect being, called god, implies the actual existence of that being because existence is a perfection, so that a being that ever failed to exist would be less than perfect. Anselm's ontological argument is an a priori proof of god's existence - explain anselm's ontological argument essay introduction anselm starts with an idea that depends on experience for their justification and then proceeds by purely logical means to the conclusion that god exists. Additionally, descartes argument regarding the existence of god is not presupposed by faith like anselm's rather, descartes begins his argument in a different manner then anselm, speaking nothing about prior faith in god's existence.
Best answer: i am hoping that you know anselm's argument after proving the existence of the cogito (i think) descartes sets out to prove god's existence. Descartes developed anselm's argument that god's existence is necessary, it is based on the idea that god exists to guarantee what can be known however, there are a few important differences to note between the argument of descartes and that of anselm (that descartes added as he developed the argument. Descartes, often called the father of modern philosophy, developed anselm's argument, in attempting to prove god's existence from simply the meaning of the word 'god' the ontological argument is a priori argument, such arguments use logic to prove an initial definition to be correct.
The second form of anselm's argument, and that which provoked greater development from descartes, concerns the nature of both contingent and necessary existence with regards to god. outline descartes' ontological argument and explain the key objections that may be used against itdescartes took the ontological argument as presented by anselm and developed it in a different form. Explain how descartes developed anselm's argument that god's existence is necessary [25 marks] the ontological argument is concerned with the being or nature of god. To unpack this line of thinking, you would first have to go through descartes' appropriation of anselm, then leibniz's critique of descartes/anselm and his reasons for changing the argument, then go through kant's reasoning about why we should not think of existence as a predicate. Anselm argues that god must necessarily exist because if god existed, only contingently, god would depend on something else for existence, and therefore god would not be as great as a being that had to exist and could not fail to exist.
Descartes gives at least two arguments for god's existence the first one, found in i14, is a version of the ontological argument for god's existence descartes' ontological argument goes as follows: (1) our idea of god is of a perfect being, (2) it is more perfect to exist than not to exist, (3) therefore, god must exist. - the ontological argument presented by descartes and the cosmological argument presented by aquinas descartes, often called the father of modern philosophy, developed anselm's argument, in attempting to prove god's existence from simply the meaning of the word 'god. 4 (a) explain how descartes developed anselm's argument that god's existence is necessary  (b) evaluate the claim that god's existence is not a logical necessity. An ontological argument is a philosophical argument for the existence of god that uses ontologymany arguments fall under the category of the ontological, and they tend to involve arguments about the state of being or existing.
Gaunilo claims that anselm's dependence in his argument on a definition of god as 'that than which nothing greater can be conceived' is flawed, as we simply cannot hold such a definition furthermore, to have this notion of god's nature in one's mind, as anselm claims, would also be impossible for our reason. Anselm's ontological argument for the existence of god anselm's argument is an a priori argument that is, it is an argument that is independent of experience and based solely on concepts and logical relations, like a mathematical. Anselm: ontological argument for god's existence one of the most fascinating arguments for the existence of an all-perfect god is the ontological argument while there are several different versions of the argument, all purport to show that it is self-contradictory to deny that there exists a greatest possible being. Anselm's ontological argument anselm's ontological argument purports to be an a priori proof of god's existence anselm starts with premises that do not depend on experience for their justification and then proceeds by purely logical means to the conclusion that god exists.
Descartes' (1596-1650ce) and st anselm's formations of an ontological argument for the existence of god form a traditional philosophical proof that has a number of flaws with it but is well-known and is still referred to. Anselm, archbishop of canterbury first set forth the ontological argument in the eleventh century this argument is the primary locus for such philosophical problems as whether existence is a property and whether or not the notion of necessary existence is intelligible. Best answer: well anselm's arguement basically says that god must exist because there is nothing we can think of greater than god descartes developes that more by saying that whatever i clearly and distinctly perceive to be contained in the idea of something is true of that thing.
