Why did Descartes prove that God exists?

This is because he finds some things difficult to explain with scientific theories, so he says so.

Maybe it's because he feels that some things are beyond his control.

Maybe it's because he has always had this belief in his heart, so he wants to prove it.

I think he can only prove it if he verifies some food that others believe in.

Descartes proved the existence of God because he wanted to confirm the existence of the external world through the existence of God. Descartes took the existence of God as the criterion for measuring the existence of things, so as to realize the transcendence process of Descartes' philosophy from "man, god and all things", not so much God played the greatest role, but the human mind. For Descartes, these were the real "gods."

Descartes can be said to elevate the practical belief in God to a certain extent, and his theories have a strong "rationalist" and "pantheistic" overtone.

From the perspective of the history of philosophy, Descartes' "I think, therefore I am" and "God exists" were developed on the basis of their predecessors, which is a kind of revolution in formalism. Descartes was great because he had certain ideas and concepts, and under the limitations of Descartes' history, he formed his own God. In fact, in the Western philosophical and scientific circles, God has always been proven and reinterpreted, as Hawking said that the first force of the great **, Newton too, but in the scientific community, this God has evolved into the supreme truth.

Thus, Descartes worked hard to prove the existence of God in order to create a more complete world and perfect mankind. God is omniscient and super-perfect. As long as people follow God, they can create perfection.

Of course, this does not exclude the possibility that he wanted to solve cognitive problems for the scientific community.

One. Ontological proof.

1) Every idea needs a reason. In fact, existence is not objectively contained in this reason, but is formal and preeminent;

2) We have the idea of God, which cannot be formally or premarkably contained within us;

3) The concept of God exists in God Himself, and therefore, God exists.

"God" in Cartesian theory is ().

a.It will deceive people Congyuan rent.

b.Honest.

c.Not cracked auspicious complete.

d.Inexistent.

Correct answer: B

Proving the existence of ()Lippi is the basic intention of Descartes to include the existence of God in philosophical issues.

a.The world of consciousness.

b.Inner world.

c.The spiritual world.

d.The material world is in the realm of tribulation.

Correct answer: d

1) Ontological proof -

1. Every idea needs a cause, and in fact sex is not objectively, but formally and preeminently contained within this reason;

2. We have the idea of God, which cannot be contained within us formally or preeminentially;

3. Therefore, the idea of God exists in God Himself; God exists.

2) Cosmological proof——

1. I can't preserve my existence from myself, otherwise I would give myself all completeness, because completeness is only an attribute of an entity, and I am an entity; But I don't give myself all perfection, so I have to rely on other beings, not myself, to preserve my existence;

2. My preservation, therefore, depends on such a being, which contains, formally or preeminently, me and anything within me, and in me the completeness and the idea of God which I lack, and therefore this completeness and the idea can only exist in this being that preserves me;

3. Therefore, such beings, formally or preeminently possess all perfection, and give this perfection to themselves, this is God, who can do all that we can clearly comprehend.

Today we will continue to introduce Descartes's classic work "The First Philosophical Meditations", and today we will talk about another important issue, that is: proving the existence of God and the immortality of the human soul.

Descartes' "I think, therefore I am" sets a precedent for the fundamental question of ontology, where we have a gifted idea of God, which appears to be God Himself, who is omniscient, omnipotent, all-good, absolutely perfect, and sovereign. This is the most complete idea, but it belongs to us, and we are imperfect, flawed, and cannot produce anything more complete than ourselves. It can only come from an absolutely perfect place outside the mind, that is, God-given, so God must exist.

Descartes' train of thought goes like this:

He first used the method of "skepticism" (i.e., the illusion of an omnipotent demon that people see and think as illusions created by this demon) to question the existence of the external world and the inner existence of others (i.e., the world we perceive may be an illusion rather than a reality), and thus comes to the conclusion that "I think, therefore I am" (Descartes believes that the fact that I am thinking is reliable, so the reliability of the fact that I exist can be guaranteed by the fact that I am thinking).

Having come to the conclusion that "I think, therefore I am", Descartes proceeds to argue that "God exists", the central thesis of which is that "everything that I can think clearly of exists": because I can conceive of an idea of an all-knowing and all-powerful (perfect) God, and my mind itself is incomplete (for I still doubt, doubt means imperfect), so this perfect idea is not possessed by my mind itself, but given to me by something from outside that is more complete than my mind; We call God the thing that has the most perfect idea. i.e. God exists.

As for 3 and 4, it is the understanding of "God = omniscient and omnipotent" and "the imperfect idea comes from the more perfect idea", and the devil is not the most perfect.

You are reading the First Philosophical Meditations, and the third meditation (i.e., on the existence of God) uses a lot of scholastic concepts, so it is not very easy to read. You can take a look at "Method Talk" first, the language of this book is very popular.

Although the six contemplations in Descartes are interlocking, in the history of philosophy, Descartes' most famous proposition is the proposition of "I think, therefore I am" (the skepticism that introduced this proposition is not highly evaluated by later generations, because if this skepticism is used thoroughly, in fact, even "I think" can be denied, and you can only get nihilism), and the most important thing in the history of philosophy should be Descartes's conceptual theory (which is expounded in the third meditation), the theory of natural mechanism and the dualism of mind and matter, His proof of God's existence is not considered to be an important thought of his thinking because of the many elements that came before him (similar ideas are found in Thomas Aquinas's five proofs of God's existence).

Your question is great. It is a critique of Descartes. In fact, Descartes could not be called a philosopher, but a physicist.

However, Descartes' "God" is not the Catholic God or the biblical God, but the God of physical nature. He believed that there was such a force that could make everything happen.

Descartes' proposition is actually wrong in terms of extreme thinking: absolute omniscience = absolute ignorance.

Prove the existence of God first, and then prove the existence of the material world.

1.I think therefore I am, but at the same time it is easy to know that I am an imperfect entity, and that I have in my heart a more complete and perfect idea of God than I am. I cannot give birth to a perfect idea of God without perfection, so there can only be a more perfect being than me who puts the idea of God into my heart, and only God can be this more perfect being who puts the idea of God into my heart.

God exists. 2.God is a fullest entity, and he exists. Its fullness determines that God does not deceive me, and that God's ability to know is valid.

Thus, Descartes overturned his previous skeptical assumption that a devil was deceiving people. Whatever is clear to us is the true concept. I have a clear idea of the existence of the physical world in my mind.

3.Because mind and matter are completely distinct, the idea of the existence of the material world cannot be generated by myself, and this idea must also come from God, and God does not deceive people, so the material world exists.

Rational treatment. To exist is to exist, and there is no need to prove it. Just like Marx, the essence of matter is matter, and there is no need to prove it.

First of all, the existence of God is the source of Cartesian deductive logic, that is, the idea of perfection was created by God, so there is no doubt about the truth of the idea. Then following this process of deductive logic, it is possible to recognize the object by understanding the idea. Specifically, I think therefore I am on this argument, that is, from "I think" (concept) - get "I am" (know).

It is added that the existence of God is not deduced in Descartes' deductive logic by "I am proceeding", but that the existence of God is a prerequisite. So you're asking the other way around.

To put it simply, it is a sentence "I think, therefore I am; I am, therefore God is here. ”

Descartes believed that when looking for a way, one should try to doubt as much as possible everything that can be doubted. The truth is unquestionable, so if you want to find the truth, you have to try to doubt everything that can be doubted, until finally you see what is not to be doubted. But he doubted for a long time, and finally found that one thing cannot be doubted, that is, I cannot doubt the person who doubts, I can doubt everything, what I see or what I hear, but I cannot doubt the person who doubts, if I doubt that I exist, then who is doubting now?

So this I who is doubting cannot be doubted, but doubt is a thought effect, and Descartes then affirms that I think, therefore I am.

When Descartes says I think, therefore I am, then affirms that I am, therefore God is. Because I doubt other things, but the truly perfect being does not doubt it, so he thinks that I am not perfect, that I am limited, but how can there be a concept of the most perfect God in this limited mind? And the imperfect I can't be the reason for this idea, because this I am not perfect and complete, so the idea of God can only come from the most perfect God himself, so God exists.
