Strengths And Weaknesses Of Descartes

In his 1971 paper “Personal Identity”, Derek Parfit posits that it is possible and indeed desirable to free important questions from presuppositions about personal identity without losing all that matters. In working out how to do so, Parfit comes to the conclusion that “the question about identity has no importance” (Parfit, 1971, p. 4.2:3). In this essay, I will attempt to show that Parfit’s thesis is a valid one, with positive implications for human behaviour. The first section of the essay will examine the thesis in further detail and the second will assess how Parfit’s claims fare in the face of criticism.

What is personal identity? This question has been asked and debated by philosophers for centuries. The problem of personal identity is determining what conditions and qualities are necessary and sufficient for a person to exist as the same being at one time as another. Some think personal identity is physical, taking a materialistic perspective believing that bodily continuity or physicality is what makes a person a person with the view that even mental things are caused by some kind of physical occurrence. Others take a more idealist approach with the belief that mental continuity is the sole factor in establishing personal identity holding that physical things are just reflections of the mind.

371). This responds to the objections raised by Thomas Reid in the 18th century (Shoemaker, 2008, p. 340), however, the Memory Theory did require a modification to include the possibility of temporarily forgetting the experiences of an earlier person-stage, “as long as one has the potentiality of remembering it” (Shoemaker, 2008, p. 340). In the conversations held by Gretchen Weirob, Sam Miller and Dave Cohen in Perry’s ‘Dialogue on Personal Identity and Immortality’ (Perry, 1977), this concept is addressed in depth. Miller relays a chapter written by Locke – “the relation between two person-stages or stretches of consciousness that makes them stages of a single person is just that the later one contains memories of an earlier one...I can remember only my past thoughts and feelings, and you only yours...take this relation as the source of identity” (Perry, 1977, p. 343). These concepts are logical possibilities in my opinion, and are far less unstable than those presented within the Body/Soul Theory, as these concepts do not require the senses of others, but the individual’s first person perception of their personal identity.

In John Locke’s argument for personal identity, he believes that we are not substances or mere souls. In his argument, Locke stresses to convey that there is a crucial difference between distinguishing a “man” and a “person” (Locke 221). According to Locke’s definition, a man is a living body which is homogenous to an animal’s body. Therefore, any living body of a particular shapes refers to a “man.” Locke emphasizes that a “person” is a sensible being that is aware of its own

In philosophy, the issue of personal identity concerns the conditions under which a person at one time is the same person at another time. An analysis of personal identity

Like many people today, Descartes believed that the mind and soul were separate. He believed that the mind’s purpose was only for “thinking” and “non-extended” things. While, the body is an extension; non-thinking. Descartes thought that the mind and body were different substances, thus they

‘Cogito Ergo Sum,’ - ‘I think therefore I am ‘ one of the most famous and well known quotes or arguments in all of modern philosophy; a phrase instantly recognizable to all those studying in the field of philosophy. This phrase refers to an attempt by Descartes to prove with absolute certainty his own existence; a systematic way to philosophize. The argument, while first proposed by ancient philosophers such as Aristotle and Saint Augustine, was utilized as an argument by French philosopher Rene Descartes in his influential text “Meditations on First Philosophy“. This argument appears in the books second meditation and provides the cornerstone for Descartes argument in the following five meditations and serves as the basis for Descartes overall metaphysical thesis, without which Descartes reasoning system would collapse. Throughout this paper I will

Descartes was incorrect and made mistakes in his philosophical analysis concerning understanding the Soul and the foundation of knowledge.  Yes, he coined the famous phrase, “I think therefore I am,” but the rest of his philosophical conclusions fail to be as solid (Meditation 4; 32). Descartes knew that if he has a mind and is thinking thoughts then he must be something that has the ability to think. While he did prove that he is a thinking thing that thinks (Meditation 3; 28), he was unable to formulate correct and true philosophical arguments and claims.  For instance, his argument for faith that a non-deceiving God exists and allows us to clearly reason and perceive was a circular argument.  Another issue with Descartes' philosophy

Personal identity, in a philosophical point of view, is the problem of explaining what makes a person numerically the same over a period of time, despite the change in qualities. The major questions answered by Locke were questions concerning the nature of identity, persons, and immorality (Jacobsen, 2016). This essay will discuss the three themes John Locke presents in his argument regarding personal identity, which are, the concept of categories, substance vs. man vs. person, and the continuity of consciousness.

Personal identity is a concept within philosophy that has persisted throughout its history. In the eighteenth century this problem came to a head. David Hume dedicated a portion of his philosophy in the attempts to finally put what he saw as a fallacious claim concerning the soul to rest. In the skeptical wake of Hume, German idealist, beginning with Immanuel Kant, were left with a variety of epistemic and metaphysical problems, the least of which was personal identity.

Since Descartes was able to think, he knew that he existed ultimately. With this in mind, Descartes reckoned that a person 's "self" illustrates their identity. Descartes states: “that he possesses a body intimately conjoined... and that he has a clear and distinct idea of himself, inasmuch...it is certain that this I [that is to say, my soul by which I am what I am], is entirely and absolutely distinct from my body, and can exist without it" (Descartes, Meditations On First Philosophy, pg.29). In fact, Descartes proposes that the body connects dually with the mind, which he believes the body is "divisible", and the mind as "indivisible", but he also informs the readers that he knows certainly who he is. Not only did Descartes deem this information as true, but he was adamant about the possibility of living without a soul. In particular, Descartes depicts a vivid picture of how the

In his Meditations on First Philosophy, Descartes strives first and foremost to provide an infallibly justified foundation for the empirical sciences, and second to prove the existence of God. I will focus on the first and second meditations in my attempt to show that, in his skepticism of the sources of knowledge, he fails to follow the rules he has set out in the Discourse on Method. First I claim that Descartes fails to draw the distinction between pure sensation and inference, which make up what he calls sensation, and then consider the consequences of this failure to follow his method. Second, I will show that in his treatment of thinking Descartes fails to distinguish between active and passive thinking.

Philosophers over time have tried to explain their understanding on the view of personal identity some of the like Rene Descartes adding the views of the existence of the material souls or egos. His views on the existence of egos suggest that people have bodies which can die but still they continue to exist. In as such other philosophers proposed diverging views from him suggesting that such a simple

Identity is what evolves us, it is what makes us think the way we do, and act the way we act, in essence, a person’s identity is their everything. Identity separates us from everyone else, and while one may be very similar to another, there is no one who is exactly like you; someone who has experienced exactly what you have, feels the way you do about subjects, and reacts the same to the events and experiences you have had. This became prevalent to me as I read through many books, that everyone goes through the process of finding who they are. A prevalent theme throughout literature is the idea that over time one develops their identity through life over time, in contrast to being born with one identity and having the same

On a shelf in the lab, lies two vats of formaldehyde, one containing the brain of Socrates, and the other containing the brain of Rene Descartes. The two brains are wired up to each other so that they can communicate with each other about their current situation.
