Rene Descartes’ Theory of Ideas has helped to shape our entire world of thought as it applies to all subjects. While it may seem to be an overstatement to say all subjects, it is not. Whether it is science, literature, or the fine arts, all of these meditations require some degree of thought. People think all day long; they are constantly and unknowingly solving problems, analyzing, detecting, observing, questioning, wondering, and sensing; yet they rarely question their ability to do so or where the knowledge comes from. In his studies, Descartes sought to discover the origin of these thoughts and abilities. Is the information in our head learned or have we had it all along and are simply remembering? Why is it that all animals, humans included, acquire a specific set of survival instincts at birth? While Descartes’ theory led to the further investigation and questioning by other philosophers, it also allowed for many discoveries in the world of psychology, as it relates to development and instinctual behavior.
Within Descartes’ Theory of Ideas lay his theory of innate ideas. He quotes, “But the chief question at this point concerns the ideas which I take to be derived from things existing outside me: what is my reason for thinking they resemble these things? Nature has apparently taught me to think this.” “According to Descartes, our minds come stocked with a variety of intellectual concepts — ideas whose content derives solely from the nature of the mind. This storehouse includes ideas in mathematics, logic, and metaphysics. Interestingly, Descartes holds that even our sensory ideas involve innate content.” Descartes is not suggesting that these ideas are merely a creation of the mind, but rather the brain; they were wr...

Although at first glance, Rene Descartes’ theory of innate ideas may not seem to have a significant place in the world of psychology, it has served and still does as a variable to consider when studying the origin of knowledge and instinctual behaviors. The theory suggests that ideas are formed from some sort of innate knowledge that is pre-written into an individual’s DNA. Many scientists may not consider it to be a helpful variable in their research because it tends to rule out room for active experimentation and leads to unanswered questions. However, even though Descartes’ theory is nothing more than a theory, it has been unable to completely prove false or null and will continue to be considered in the world of philosophy and psychology alike.
Review of Descartes: An Intellectual Biography and Descartes' Error: Emotion, Reason, and the Human Brain
This philosophical study will support the theory of interactive mind/body dualism in the writings of Renee Descartes. The distinction between the energy of the mind is typically separated from the function of the body, yet Descartes found that they interacted to form thoughts. Descartes’ theory of dualism also defines how the mind can generate thoughts through the bodily function of the brain. In this context, Descartes found that the pineal gland was an example of a bodily organ, which could transmute the pneuma (aka. the spirit) to generate a thought through the mind. This type of mind and body interaction successfully defines Descartes dualism in the development of the thought process. The pineal gland supports the contention that the brain must work in conjunction with the mind I the formation of human consciousness. In essence, Descartes’ interactive dualism defines the cooperative operations of the brain and the mind that work to form thoughts through the pineal gland and the pneuma.
The mind which is a non-extended thing, thinking is very different from the body which is a non-thinking thing, an extended and therefore Descartes argues that it is possible for the body to function without the mind and the mind to function without the body (Sorabji, 72). In Descartes theory of mind-body dualism, there exist several theories. Descartes describes the real distinction as the distinction between two things or substances. A substance is something that does not require any other creature to exist since it can occur with God’s concurrence only. Mode, on the other hand, is the affection towards a particular substance. Descartes argues that there are two payoffs for arguing that the mind and body can exist without each other. This includes the religious motivation and provides hope for the immortality of the soul and the second one is the scientific motivation that paves way for the new version of Descartes mechanistic
According to Descartes, “because our senses sometimes deceive us, I wanted to suppose that nothing was exactly as they led us to imagine (Descartes 18).” In order to extinguish his uncertainty and find incontrovertible truth, he chooses to “raze everything to the ground and begin again from the original foundations (Descartes 59).” This foundation, which Descartes is certain to be the absolute truth, is “I think, therefore I am (Descartes 18).” Descartes argues that truth and proof of reality lies in the human mind, rather than the senses. In other words, he claims that the existence of material objects are not based on the senses because of human imperfection. In fact, he argues that humans, similarly to Plato’s Allegory of the Cave, are incapable of sensing the true essence or existence of material objects. However, what makes an object real is human thought and the idea of that object, thus paving the way for Descartes’ proof of God’s existence. Because the senses are easily deceived and because Descartes understands that the senses can be deceived, Descartes is aware of his own imperfection. He
Does God exist? Philosophers and individuals alike have searched to find the answer to this question. Some may believe in resurrection, others in Dante’s Inferno, however philosophy aims to answer such ethical questions using skepticism as an approach. The premise of The Meditations by René Descartes, questions whether the immortal soul is real and if there is a God. Descartes concludes that God does exist, justifying his reasoning with the fact that he thinks. If one thinks, one exists. This conclusion leads to a discussion between the mind existing separately from matter. If one exists, one is mind. Immanuel Kant argues that morality is based on reason. Individuals act from maxims which are the basis to one’s rationale. Reason is universal.
Ideas, innovations, and inventions are all created from brilliant minds. Than how did these ideas come to be? Descartes believes that God is the cause of new innovations adding, therefore God instilled in us the idea of his existence. Explaining, in order for us to draw an idea from a presumption or thought, than an object must have been derived not by us but rather God. An example of his presumption of the existence of God would be the fact that if one cannot imagine a bookshelf without books. Whether one exists or not, it is true than that they cannot be separated from each other. Descartes follows by stating that “he cannot conceive God without existence, existence is inseparable from him.”
Unlike one of empiricism’s major tenets, Tabula Rasa, or blank slate, Descartes believed that the mind was not a blank slate, but actually came pre-loaded, if you will, with ideas, which are part of our rational nature and that our rational nature allows us to grasp . Descartes begins his journey deep within his own mind by claiming that all truths can be conceived by thinking about them. He calls his method cogito or pure reasoning. His famous words “I think, therefore I am,” describes the way that he thinks the mind is the true reality with the rest of reality being an extension. His example to prove thi...
René Descartes was the 17th century, French philosopher responsible for many well-known philosophical arguments, such as Cartesian dualism. Briefly discussed previously, according to dualism, brains and the bodies are physical things; the mind, which is a nonphysical object, is distinct from both the brain and from all other body parts (Sober 204). Sober makes a point to note Descartes never denied that there are causal interactions between mental and physical aspects (such as medication healing ailments), and this recognition di...
Descartes claims that intellect as thinking being extended as to the Aristotelian claiming intellect as a thought. He claims that there must be a conception of what the thing that thinks underlies the Cogito inference in which registers these sufficient grounds. He establishes this argument by suggesting that it must exclude anything that requires the existence of anybody from the essential properties of the ‘they’ that thinks. Therefore claiming that mind is an extended thinking thing and the body being a non-extended thinking thing. He established these claims by first questioning everything he sees and doubting of everything that he sees is false and that his deceitful memory represents ever existed. Also excluding the senses and questioning
Descartes makes a careful examination of what is involved in the recognition of a specific physical object, like a piece of wax. By first describing the wax in a manner such that “everything is present in the wax that appears needed to enable a body to be known as distinctly as possible” (67), he shows how easily our senses help to conceive our perception of the body. But even if such attributes are modified or removed, we still recognize the changed form, as the same piece of wax. This validates Descartes’ claim that “wax itself never really is the sweetness of the honey, nor the fragrance of the flowers, nor the whiteness, nor the shape, nor the sound” (67), and the only certain knowledge we gain of the wax is that “it is something extended, flexible, and mutable” (67). This conclusion forces us to realize that it is difficult to understand the true nature of the wax, and its identity is indistinguishable from other things that have the same qualities as the wax. After confirming the nature of a human mind is “a thinking thing” (65), Descartes continues that the nature of human mind is better known than the nature of the body.
Rene Descartes’ natural light is his saving grace, and not Achilles’ heel. Descartes incorporates the concept of natural light within his epistemology in order to establish the possibility of knowing things completely without doubt. In fact whatever is revealed to the meditator via the natural light is considered to be indefeasible. The warrant for the truth of these ideas does not rely on experience or the senses. Rather the truth of the idea depends on viewing the concept through clear and distinct perception. Descartes’ “I am, I exist”, (Med. 2, AT 7:25) or the ‘cogito’ is meant to serve as the basis for knowing things through clear and distinct perception. Descartes’ cogito is the first item of knowledge, although one may doubt such things as the existence of the body, one cannot doubt their ability to think. This is demonstrated in that by attempting to doubt one’s ability to think, one is engaging in the action of thought, thus proving that thinking is immune to doubt. With this first item of knowledge Descartes can proceed with his discussion of the possibility of unshakeable knowledge. However, Descartes runs into some difficulty when natural light collides with the possibility of an evil genie bent on deceiving the meditator thus putting once thought concrete truths into doubt. Through an analysis of the concept of natural light I
Descartes emphasizes the idea that his idea of God's existence does not originate from his senses. Rather than having created the idea himself, he states that God himself imprinted the idea on him. “Thus the only option remaining is that this idea is innate in me just as the idea of myself is innate in me” (Descartes, 34). If a person is to believe that innate ideas exist, it follows that the existence of innate ideas is a truth.
Rene Descartes decision to shatter the molds of traditional thinking is still talked about today. He is regarded as an influential abstract thinker; and some of his main ideas are still talked about by philosophers all over the world. While he wrote the "Meditations", he secluded himself from the outside world for a length of time, basically tore up his conventional thinking; and tried to come to some conclusion as to what was actually true and existing. In order to show that the sciences rest on firm foundations and that these foundations lay in the mind and not the senses, Descartes must begin by bringing into doubt all the beliefs that come to him by the senses. This is done in the first of six different steps that he named "Meditations" because of the state of mind he was in while he was contemplating all these different ideas. His six meditations are "One:Concerning those things that can be called into doubt", "Two:Concerning the Nature of the Human mind: that it is better known than the Body", "Three: Concerning God, that he exists", "Four: Concerning the True and the False", "Five: Concerning the Essence of Material things, and again concerning God, that he exists" and finally "Six: Concerning the Existence of Material things, and the real distinction between Mind and Body". Although all of these meditations are relevant and necessary to understand the complete work as a whole, the focus of this paper will be the first meditation.
The teaching of Descartes has influenced many minds since his writings. Descartes' belief that clear and distinct perceptions come from the intellect and not the senses was critical to his ultimate goal in Meditations on First Philosophy, for now he has successfully created a foundation of true and certain facts on which to base a sold, scientific belief structure. He has proven himself to exist in some form, to think and therefore feel, and explains how he knows objects or concepts to be real.
Rene Descartes, a 17th century French philosopher believed that the origin of knowledge comes from within the mind, a single indisputable fact to build on that can be gained through individual reflection. His Discourse on Method (1637) and Meditations (1641) contain his important philosophical theories. Intending to extend mathematical method to all areas of human knowledge, Descartes discarded the authoritarian systems of the scholastic philosophers and began with universal doubt. Only one thing cannot be doubted: doubt itself. Therefore, the doubter must exist. This is the kernel of his famous assertion Cogito, ergo sum (I am thinking, therefore I am existing). From this certainty Descartes expanded knowledge, step by step, to admit the existence of God (as the first cause) and the reality of the physical world, which he held to be mechanistic and entirely divorced from the mind; the only connection between the two is the intervention of God.
