Analysis Of René Descartes: The Existence Of Self

1074 Words3 Pages

In his work Meditations on First Philosophy, René Descartes defines his existence, being the only concept he can perceive as true. Existence of self is a necessity that arises simply from introspective thinking; one exists “since [one can persuade himself or herself] of something” (Descartes). This definition gives rise to a separation of the human entity, as what defines a person is not the physical but rather the nonphysical (Descartes). Descartes’ view of two separate essences of a person constitutes a theory known as substance dualism, which states that humans are composed of two elements: a material component (which is purely physical and makes up the “body”) and a mental component (all cognitive thinking which makes up the “soul”) (Kleinman …show more content…

Suppose that an emergency vehicle, with sirens blaring, speeds down the street in front of a house in which two people are sleeping. Both people hurriedly awake from their sleep due to the proximity of the cacophonous sirens, anxious that the vehicle might be responding to an emergency near the residence. However, both soon realize that the vehicle is only passing by the house on its way to the true emergency. Upon this discovery, Person A’s anxieties about immediate danger are alleviated, and he or she drifts back to sleep. In contrast, annoyance and frustration that his or her restful sleep has been interrupted causes Person B to be unable to return to sleep. These composite people demonstrate a unique difference between the body and the soul. In this scenario, the body garners obvious information from the environment; both people audibly perceive the sirens of the vehicle and subsequently respond by arousing from their sleep. The sound could be measured and quantified by a definite figure, such as one hundred and twenty decibels (“Noise”). Other data, such as the time and date the vehicle passed, could be …show more content…

These mental sensations of the soul cannot be explained by any simplistic illustration, as can be readily evidenced through modern technology. Machinery can be programmed to perform several of the basic physical tasks that humans can perform (Nagel). A baby doll, for instance, can respond to stimuli and cry or perhaps verbalize a simple phrase. Yet, while this baby doll behaves similarly to a human, it is not truly responding to a complex environment; instead, it is restricted by its programming (Nagel). The baby doll will never learn a new phrase to say, and it will not always cry when the same event occurs. In fact, it may cry for no real reason at all. This distinguishes humans from such technology. People have “conscious [experiences]” (Nagel) that are unique to each individual’s soul, reinforcing the division between mind and
