If Descartes "proves" one's own existence through cohort's argument and recognizes that one's own is the essence of thinking, he must look to the research of the world around him. But before doing so, he thought he would study the problem of the existence of God better. If he could prove that he was created by a completely merciful Creator, God placed these ideas on not a crook and in Descartes, so his natural idea is the same You must tell the truth.
From his hypothesis, it is clear that his idea proves his existence. Then he discussed the existence of God. According to Descartes' philosophical point of view, God created the two essentials that make up the whole reality. One is to think about substances and thoughts and the other is to extend substances and objects. In the field of physiology, Descartes believes that part of the blood is a subtle liquid. As he believes it comes in contact with the thought substance in the brain and flows out along the nerve channel which makes the muscle and other parts of the body vivid.
According to Descartes, when two substances are present separately from each other, the two substances are certainly distinguished. Therefore, Descartes believes that God is different from humans, human body and mind are different from each other. He thinks that the big difference between the body (expanded one) and the mind (unexpanded, unimportant) makes two of the ontologies different. But the heart is completely indivisible. Because, "When thinking about the mind or thinking about something, I can not distinguish any part of myself, I understand that I am very single and complete."
According to Descartes, everything we have is a natural idea. She believes that there is a merciful God who provides us with the senses and thoughts we can not deceive. By proving that God exists in her meditation, God is not a con artist, so we prove that everything we know is clearly true (Descartes, 2008). She applied even more complete laws of reality, and it stated that in order to create something the Creator must have more reality than God creates to put her ideals in her (Cartier , 2008). Since God is most realistic, then we can rely on our emotions to achieve. Therefore, through Descartes' philosophy, we can prove that the world we are experiencing is reality and not the dream of living in Plato caves or the life trapped in the matrix.
Second argument about the existence of God. Because Descartes believes the existence is perfect, it can become a predicate to God. First, I will explain what the ontological argument of the existence of God is. Next, I will explain why Descartes decided to incorporate God into his philosophical approach. As a predicate of God existence reveals some truth about God. Ontology seeks to prove the existence of God from a transcendental point of view
