The problem with rené descartes' argument about the existence of god has to do with his rationalist deductive reasoning descartes deduces that truth about the existence of god lies within his idea of a perfect god and god's essence (as a perfect being who must exist in order to be perfect) a. Descartes responds that this overlooks two things: first, his claim that clear and distinct ideas are true and second, that necessary existence as part of the concept of god entails. Descartes proof for the existence of god the purpose of my essay will be to examine descartes' argument for the existence of god first, i will review descartes' proof for the existence of god.
In order to do this, descartes posits he must make an argument that avoids critics' accusations that the proof relies on circular reasoning in proving the existence of god from a philosophical level, he would be able to appeal to non-believers as well. In addition to this, descartes faces an even bigger problem: he was writing at a time when it when it was unthinkable to call god's existence into question by writing about a deceptive god, descartes risked being discredited as a scholar. Descartes's fifth meditation argument for god's existence relies on an untenable notion that existence is a perfection and that it can be predicated of god i shall first explain what descartes's argument for god's existence is, and then present his argument in propositional form. 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.
For descartes, because it is clear and distinct that the idea of a perfect god must hold that god has necessary existence, and that if i have an idea of something and i clearly perceive it to have a property then that thing really has that property, then god must exist because god's existence naturally follows from god's conception. When descartes demonstrates the necessity of god's existence, he establishes an antidote to the hyperbolic doubt posited in the first meditation, clearing the way for a rationalist explanation for knowledge of the empirical world. Descartes' arguments for the existence of god are ontological arguments: they are deductive and a priori proofs for the existence of god they aim to be the sort of argument such that if the premises are true, then the conclusion must be true. In fact, descartes' argument doesn't really need the appeal to god's omnipotence at all given that he can know that his clear and distinct ideas are true, and he clearly and distinctly perceives that the essence of mind and the essence of body are fundamentally. Descartes argument barely gets off the ground one cannot doubt the existence of doubt, and therefore the existence of something, some form of thought, which one can appropriately label a manifestation of oneself.
Furthermore, descartes saw that there is no reason to doubt the existence of god since his perception and understanding of god is an infinite reality and therefore is more likely to be authentic than other conceptions. Descartes' ontological (or a priori) argument is both one of the most fascinating and poorly understood aspects of his philosophyfascination with the argument stems from the effort to prove god's existence from simple but powerful premises. Since there is no doubt about this possibility for descartes and given the fact that god is all powerful, it follows that god could bring into existence a mind without a body and vice versa just as descartes clearly and distinctly understands them.
An earlier causal argument for god's existence in the third meditation, raising questions about the order and relation between these two distinct proofs descartes repeats the ontological. Big idea 5: from the foundational belief in the existence of the internal world, you can prove the existence of god (through the ontological argument) this gives descartes his first inferential belief. Descartes: starting with doubt for a more complete formal presentation of this foundational experience, we must turn to the meditationes de prima philosophia (meditations on first philosophy) (1641), in which descartes offered to contemporary theologians his proofs of the existence of god and the immortality of the human soul.
Descartes' causal argument for the existence of god 419 the assumption is made that d) we have a coherent idea of god i shall divide the paper into two more or less independent sections. 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 argument for the existence of god is thus not convincing which has great implications for the descartes' philosophical project without knowledge of god descartes remains in the whirlpool of doubt he has thrown himself into in the first meditation and can not know anything except that he exists.
The existence of god essay the ontological argument aims to prove the existence of god as an a priori argument one of the distinguishing features of descartes's argument is its simplicity. To move along the circle descartes uses a version of anselm's ontological argument, and given the dubious assumptions needed to make it work it is hard to believe that one can be convinced of god's existence based on that alone. Even though descartes came up with such original arguments with the attempt to prove the existence of god, philosophers who succeeded him ie hobbes critiqued his proofs as being so narrow and greatly relying on a premise that an image god is only present within mankind.
