What Did Descartes Want To Prove? A Comprehensive Analysis

Descartes, a renowned philosopher, sought to prove something that would have a profound impact on the way we understand knowledge and existence.

His quest for certainty led him to explore the possibility of the existence of a higher power, and he presented two compelling arguments to support his belief.

In this article, we will delve into Descartes’ philosophical journey and examine the proofs he put forth to establish the existence of a supreme being.

Join us as we explore the mind of one of history’s greatest thinkers and uncover the secrets behind his quest for certainty.

What Did Descartes Want To Prove

Descartes’ ultimate goal was to establish a foundation of certain knowledge. He believed that without certainty, we cannot truly understand the world around us.

To achieve this, Descartes sought to prove the existence of a higher power. He believed that if he could prove the existence of a supreme being, then he could establish a foundation of certainty upon which all other knowledge could be built.

Descartes presented two main arguments to support his belief in the existence of God. The first argument, known as the cosmological argument, used the concept of infinity to prove that there must be a higher power that created the universe.

The second argument, known as the ontological argument, focused on the idea that existence is superior to non-existence. Descartes argued that since God is a perfect being, he must exist because non-existence would be an imperfection.

Through these arguments, Descartes sought to establish the existence of God as a necessary truth. He believed that this proof would provide a foundation of certainty upon which all other knowledge could be built.

Introduction To Descartes And His Quest For Certainty

René Descartes, often referred to as the “Father of Modern Philosophy,” was a French philosopher who lived in the 17th century. He sought to break away from the traditional Scholastic-Aristotelian philosophy of his time and develop a new, mechanistic approach to science. Descartes believed that the Scholastics’ method of relying on sensation as the source for all knowledge was prone to doubt. He wanted to replace their final causal model of scientific explanation with the more modern, mechanistic model.

To achieve his goal of establishing a foundation of certain knowledge, Descartes employed a method of doubt. He considered false any belief that falls prey to even the slightest doubt. This “hyperbolic doubt” then served to clear the way for what Descartes considered to be an unprejudiced search for the truth. This clearing of his previously held beliefs then put him at an epistemological ground-zero.

From this point, Descartes set out to find something that lies beyond all doubt. He eventually discovered that “I exist” is impossible to doubt and is, therefore, absolutely certain. It is from this point that Descartes proceeded to demonstrate God’s existence and that God cannot be a deceiver. This, in turn, serves to fix the certainty of everything that is clearly and distinctly understood and provides the epistemological foundation Descartes set out to find.

Descartes presented two main arguments to support his belief in the existence of God – the cosmological argument and the ontological argument. Through these arguments, Descartes sought to establish the existence of God as a necessary truth, providing a foundation of certainty upon which all other knowledge could be built.

The First Proof: The Ontological Argument

One of Descartes’ main arguments for the existence of God is the ontological argument. This argument is based on the idea that existence is a necessary attribute of a perfect being. Descartes believed that God, as a supremely perfect being, must exist because non-existence would be an imperfection.

Descartes’ ontological argument is often misunderstood because of its simplicity. However, the argument is grounded in two central tenets of his philosophy – the theory of innate ideas and the doctrine of clear and distinct perception. He relied not on an arbitrary definition of God but rather on an innate idea whose content is “given.”

The argument proceeds from the clear and distinct idea of a supremely perfect being. Existence is derived immediately from this idea. Descartes often compared the ontological argument to a geometric demonstration, arguing that necessary existence cannot be excluded from the idea of God anymore than the fact that its angles equal two right angles can be excluded from the idea of a triangle.

Descartes’ version of the ontological argument differs from Anselm’s in important ways. Anselm’s version is thought to proceed from the meaning of the word “God,” by definition, God is a being greater than which cannot be conceived. Descartes’ argument, in contrast, is grounded in innate ideas and clear and distinct perception.

Despite objections raised by some of the leading intellectuals of his day, Descartes defended his ontological argument in several central texts. He believed that if he could prove the existence of God as a necessary truth, then he could establish a foundation of certainty upon which all other knowledge could be built.

The Second Proof: The Cosmological Argument

The cosmological argument, also known as the causal argument, is based on the concept of causality. Descartes believed that everything in the world has a cause and that there must be a first cause that started everything in motion. This first cause, according to Descartes, must be God.

Descartes’ argument begins with the observation that everything in the world has a cause. He then reasons that this chain of causes cannot go on infinitely, because an infinite regress of causes would mean that there is no ultimate cause or explanation for the existence of the universe. Therefore, there must be a first cause that started everything in motion.

Descartes argued that this first cause must be God because only God has the power to create something from nothing. He believed that the universe could not have created itself and that there must be a higher power responsible for its creation.

The cosmological argument was not unique to Descartes. It had been used by philosophers for centuries before him. However, Descartes’ version of the argument was notable for its emphasis on the concept of infinity. He believed that the infinite nature of the universe required an infinite being to explain its existence.

In any case, Descartes believed that his cosmological argument provided a strong basis for his belief in God’s existence. He saw it as one of two pillars upon which his entire philosophy rested.

Criticisms And Controversies Surrounding Descartes’ Proofs

Despite Descartes’ efforts to establish a foundation of certain knowledge, his proofs for the existence of God have been met with criticism and controversy.

One major criticism of Descartes’ cosmological argument is that it relies on the assumption that everything must have a cause. Critics argue that this assumption is not necessarily true, and that there may be things that exist without a cause.

Similarly, the ontological argument has been criticized for its reliance on the concept of perfection. Critics argue that perfection is a subjective concept, and that what may be considered perfect by one person may not be considered perfect by another.

Additionally, some philosophers have questioned whether Descartes’ proofs actually achieve their intended goal. They argue that even if the existence of God can be proven, it does not necessarily follow that all other knowledge can be built upon this foundation of certainty.

Another controversy surrounding Descartes’ proofs is the question of whether they are circular. Some critics argue that Descartes’ proof for the existence of God relies on premises that are themselves based on the assumption of God’s existence.

Despite these criticisms and controversies, Descartes’ work remains influential in the field of philosophy. His ideas about the nature of knowledge and the existence of a higher power continue to be studied and debated by philosophers today.

The Impact Of Descartes’ Philosophy On Modern Thought And Understanding Of Existence.

Descartes’ philosophy had a profound impact on modern thought and our understanding of existence. His method of doubt, which involved questioning all previously held beliefs, paved the way for a more critical approach to knowledge acquisition. This approach has influenced modern scientific inquiry, which relies on empirical evidence and rigorous testing to establish facts.

Descartes’ dualism, which posited that the mind and body are separate entities, has also had a lasting impact on modern philosophy. This idea challenged the traditional view of the soul as an indivisible part of the body and opened up new avenues for exploring the nature of consciousness.

Furthermore, Descartes’ mechanistic view of the universe as a complex machine governed by natural laws laid the foundation for modern physics and our understanding of the physical world. His emphasis on mathematical reasoning and analytic geometry also paved the way for advancements in mathematics and science.

Overall, Descartes’ contributions to philosophy, mathematics, and science have had a lasting impact on modern thought and our understanding of existence. His ideas continue to shape our understanding of the world around us and inspire new avenues of inquiry and discovery.
