How Did Rene Descartes And John Locke Question Personal Identity?

Improved Essays
Rene Descartes and John Locke are some of the first philosophers to question personal identity and although they both bring up valid points I tend to lean towards Descartes rationalistic view. The reason we see such different distinguishable arguments is because of the different approaches that these philosophers took. You see, Descartes was a rationalist, which means that beliefs that we form should be based off reason rather than emotion. While, Locke was an empiricist, which was someone who believed that intelligence came from sensory experience. When we think of personal identity we ask ourselves what makes us who we are, we are trying to identify ourselves, find out what makes us unique and different from one another.

There are traditionally two answers to this problem that have been widely accepted. The first one by Descartes is that the sameness of person over time is the sameness in soul over time. The soul is essentially a non-physical thinking substance that is distinct from the body. For person A and B to be the similar to person B “it is necessary for A and B to have the same soul. Sameness of the body is not relevant to personal identity. Person A could have a completely different body than B but still be the same if they share the same soul. I agree with because, like the saying goes it’s not what’s on the inside but the outside that counts. Now Locke was completely revolutionary, he essentially rejected Descartes theory and came up with a completely different account. Locke said that to be the same person you do not have to have the same soul or body but the same consciousness. Locke is famous for his concept of “tabula rasa” which means clean slate, he is saying that a child is born into the world innocent and forms his/her personal identity through experiences in their life. What Locke means by sameness of consciousness is that a later person B must exhibit the same consciousness as person A did and this only applies if the later person can remember person A’s thoughts and actions. We can see the different accounts that made both Descartes and Locke famous …show more content…
That being said, I do not completely disagree with Locke, but he does have some flaws with his theory and Thomas Reid raised some concerns for Locke. Reid used the example of a young lieutenant in the military, which could remember what he did as a child. Let’s say that when he was younger, he remembers cheating on a test, but then when he became a general, he remembers what he did as a lieutenant but cannot remember his childhood. He had completely forgotten the time when he cheated on the test. So if memory constitutes personal identity, then the lieutenant is the same person as the child and the general is the same person as the lieutenant but the old general is not the same person as the child. This happens to be a contradiction because if identity is a transit of memories, then A is identical with B and B is identical with C, A is then also identical with C. This is why I argue with Locke’s theory because if you cannot remember what you did as a child, a year ago, six months ago, yesterday; does this mean you are not the same person because we may sometimes forget

    Both Locke and Hume agree that there must be different definitions of identity for different things; you can’t define a pile of rocks and a living tree using the same method of identity. However, there is a contrast in the methods used to identify self. Locke said that both “The body, as well as the soul, goes to the making of a man,” (Locke 15). What then ties these together into self is basically continued consciousness.…

    Locke was a philosopher who claimed that personal identity was independent of all substances, including immaterial substances. Locke says that we continue to be the same person over time if we have the same conscious experience over our lifespan, meaning psychological continuity is the criterion for personal identity. He actually has three different criteria for the continuity of people: psychological continuity, meaning the person at the later time is psychologically continuous of the person at the earlier time; consciousness criteria, meaning the person at the later time and the person at the earlier time have the same consciousness; and memory criteria, meaning the person at the later time must remember the experiences of the person at the…

    Although this is a common belief, it comes with many problems. One of the most concerning issues is the problem of circularity. It is important to first note that, in the words of Schechtman, “The circularity objection itself relies on a claim that memory, by definition, presupposes personal identity,” (Schechtman, Pg. 42). This means that the initial assumption with this concept is that memory and personal identity have an interconnected relationship that cannot be undone. If we look at an individual’s memories, we can see how they indicate personal identity.…

    That is, only Person B is supposed to have Person B’s identity. Thus, it seems illogical that Persons A and C would share Person B’s identity, because then Person B’s identity would no longer be unique, and therefore, no longer an identity, thus showing why the duplication problem makes memory theory appear false. However, on page 31 of Perry’s book, Perry, through the character Cohen, claims that “We can say that the rememberer is the one of the two whose memories were caused in the right way by earlier experiences”. Essentially, this means that in order for a memory to be considered a real memory, and not an apparent memory, the memory must have been created as a result of something experienced by the rememberer. Thus, there is a connection between an agent performing an action and a memory being formed as a result of that action.…

    The answers to those questions for Descartes are radically different than those of Locke. The former comes from a rationalist’s point of view while the later comes from an empiricist point of view. There is a historical debate between Descartes and Lock regarding innate ideas. Innate ideas in Descartes point of view are engraved in the mind since birth. On the other hand, Lock goes against that idea but gives incomplete answers…

    France During the 18th century, new political ideas greatly influenced the French revolution, which was the turning point in French history. Indeed, one of the most important and influential philosophers ever named John Locke (1632-1704) had a profound impact on French thinkers and the revolution. French philosophers of the Enlightenment took Locke as a model. He was the promoter of a political philosophy based on the concept of natural law where all men collectively elect a government to protect their natural rights.…

    The theory of Functionalism, the thought that the mind is not identical to the brain, but it is the way the brain functions. For example, information that is convoluted and is within something else is the mind; the thing it is in is the brain, no matter what it is in (if the mind was made up of something other than the brain). The idea behind this theory is that the mind is just the way the brain is usefully arranged. Conceivably the mind can be placed into, downloaded, or passed on to another brain and still function like it once did because the mind is to the brain (mind = brain program), and the mind is not the brain. To believe in functionalism and think of what it is like to be in a mental state, it is to not be in a brain state.…

    This clearly cannot be true, as it is not logical to disagree saying they are not the same person. This then could lead us to think of personal identity being down the physical continuity of a person, where they remain in the same body and that is what is important for personal identity. It seems absurd for Locke to claim that they are not the same people. Lockean theorists refuted the argument by saying that this example can prove that psychological continuity is what is important, as although the Old General does not remember flogging, the Solider does remember it, so there is still a continuous line of memories. It is not essential that all memories are remembered for the duration of a person’s life, according to Locke, it’s whether the memories overlap and could be remembered at different stages of the person’s life that is important for personal…

    There won’t be any other person who will have the same exact type of memories as you as Locke proved that it is impossible for someone to be at the same place at the same exact time and to be in two places at once. Since you cannot be at the same place at the same time, it means that everyone will have different beginning and if you have different beginning then that means your string of consciousness will differ from everyone and that leads us to the point that your consciousness is tied your person identity For instance, even if you have an identical twin who has the same matter as you and even the same DNA, one thing that will not be the same is your memories, which leads John Locke to conclude that it isn’t either mental or physical matter which is your personal identity but instead personal identity consists in continuity of…

    Two philosophers that have heavily influenced the world of philosophy as we now know it, René Descartes and John Locke, have not always agreed on the same beliefs. In fact, they almost always argued on what each other felt was true except for the unlikely agreement on a few things. This brings me to one particular argument dealing with the issue on innate ideas. Descartes side of the argument believes that we born with ideas (innate ideas) and Locke believes our ideas come from experience and the senses. Ideas have to stem off of something and the only way for us to have that base for an idea is to experience it.…
