Analysis Of Cratylus By Plato

Source of All Knowledge

At the end of Cratylus by Plato the source of all knowledge is discussed. Despite Socrates’ objections against Cratylus’ extreme naturalism throughout their dialogue, Cratylus still argues that etymology (the study of word origins) is the only reliable path for the pursuit of knowledge. Socrates however doubts Cratylus by pointing out: the degree of trust given to legislators (ones that have the power to name things), where they got their knowledge from and the coherence of word(s) being right and wrong consistently throughout changes and transitions of language (flux).
Thus for Socrates, nothing in flux could be known because the continuous process of transition will yield no knowledge. He further states “but if that

Referred to as Mentalese, this language is innate and provides us with a set of rules to understand the description of things. To have these rules, you must already be able to internally represent that rule i.e. using the words in Mentalese. Fodor suggests that the source of all our knowledge can be broken down to simple blocks of internal representations in Mentalese. For example, the knowledge of “chairness” entails having an innate ability to internally represent its rules. The rules explain what counts as a chair (Martin …show more content…
During the learning process of associating an object to a predicate, the latter could have been in transition. So one would not know whether it is right or wrong and in this case it would be both coherently.
However a private language of thought also suggests that the origin of words is not important in the pursuit of knowledge; it is actually rather irrelevant. To have knowledge of a word is to have mental representations of the predicates it belongs to. This is done by our internal language of thought which is basically neurological activity in the brain. For example the knowledge of “cat” is being able to represent the concept of “cat” in the brain. This is acquired by some kind of neurological pattern that informs about the characteristics of a “cat” (“is an animal”, “is cute”, etc.).
Socrates also questions where the legislators got their knowledge from, and whether they are reliable authority to base this knowledge on. According to Fodor we already have an innate language of thought that we use to represent things and concepts in our brain. Thus when the legislators assign names, they already had an innate ability to represent the object they are referring to in their brains. Its name then is associated with the representation in our innate language of thought i.e. the word in Mentalese. This means that the origin of words is a reliable source of knowledge as by uttering and learning

    In the two texts that we read in class, Plato, Phaedo, and Lucretius, Nature of Things, both Socrates and Lucretius try to reassure us that we should not be afraid of death. In Plato, Phaedo, Phaedo is telling the story of Socrates’s final hours from being their first hand. In Lucretius, Nature of Things, Lucretius’s telling his view on religious issues and how he got to his view, poetic skills, and study on scientific phenomena.

    Socrates studies all things in the sky and below the earth rather than just studying the gods. Socrates has learned that the politicians know little about the questions of life but, that does not stop them from trying to give answers. Socrates admits he knows nothing and the fact that he knows this makes him smarter than everyone else. “I am wiser than this man; it is likely that neither of us knows anything worthwhile, but he think he knows something when he does not, whereas when I do not know, neither do I think I know; so I am likely to be wiser than he to this small extent, that I do not think I know what I do not know.…

    The reoccurring theme of knowledge is displayed in Plato`s literary works such as, Meno, Apology and The Cave. In these literary works it exemplifies that although one may think that one has perfect knowledge one has much more knowledge to obtain. In Plato`s Meno, Meno expresses that when someone does something bad it is because that person did not have the exact knowledge to know it was bad. Socrates walks around Athens questioning people…

    I propose we weaken the standards of how Plato construes knowledge, or at least how he entertains this notion of knowledge. We need not weaken it to the extent that we lose Plato’s fundamental requirements for knowledge (i.e. true belief and the ability to give an account). I argue that ‘partial,’ perhaps marginal, knowledge allows us to hold all the standards Plato stipulates and come to learn knew things. Thus, perhaps we can avoid Meno’s paradox. What this solution attempts to do is reject the former disjunct (i.e. we have knowledge of x) but preserve the latter.…

    The world of semantics is dominated by two types of naming theories: descriptivist and causal. Defenders of these two theories seem to discredit each other, thinking the world of semantics must choose one or the other. I, however, do not believe this has to be the case. In this essay I will argue that parts of descriptivist and causal theories of names can come together to create a better overall theory of names: a hybrid theory. I will do this by looking at the argument Gareth Evans makes in his article, “the Causal Theory of Names”.…

    Unlike them, Socrates could acknowledge his ignorance and “was conscious of knowing practically nothing,” (22d). This is what gave him an advantage of being wiser than everyone else. In the matter of his defence, these encounters are what encouraged people’s hatred towards him because people thought they were being challenged and interrogated by Socrates, failing to understand his sense of virtue as a philosopher in examining both himself and others. However, in “The Paradox of Socratic Ignorance in Plato’s Apology,” the authors point out that Socrates believes his conviction to be absolute because “he {was} certain that philosophizing with…

    It describes the final conversations between Socrates and his close friends before he is put to death. The entire dialogue focuses on the matter of death and what happens to our souls after we die. Socrates presents four arguments to prove the immortality of the soul, one of which is the “Argument from Opposites,” in which he conveys that all things come to be in existence from their opposites. This is Socrates’ first argument that he presents, and although it is supported with great detail, it lacks the support that is necessary to prove that the soul is immortal. Socrates uses an extensive amount of contradictory opposites to support his claim such as sleeping and waking up, and faster and slower, however these do not properly compare to being alive and being dead because they are contrary opposites.…

    Plato’s Doctrine of Recollection is a theory of “learning” which aims to solve the issue of how one may learn something when one does not know what the thing is. Despite successfully and adequately addressing the paradox proposed by Meno, the Doctrine of Recollection fails to adequately address issues of its own circularity (as proposed by Edward Fraser) and also fails to address the issue of the regress problem. Perhaps one of the clearest instances where we learn of the Doctrine of Recollection occurs in Plato’s Meno. Meno, the interlocutor opposite Socrates, asks Socrates the question: “…how are you going to inquire about it, Socrates, when you do not at all know what it is?”…

    Just as mentioned in Meno, the thought that learning is no other than recollection remains a key point in the argument in Phaedo’s dialogue. Socrates talks about how “recollection can be occasioned by things that are similar, but it can also be occasioned by things that are dissimilar” (Plato, Phaedo 74a). By this, he means that the sight of something can make one think of another thing. As an example, Socrates uses lovers and how seeing an object that their beloved might use would remind them of the lover. He also says how, in a similar way, when one sees “a picture of Simmias, [they] recollect Simmias, himself,” and gives this as the explanation for the process of recollection (Plato, Phaedo…

    The purpose of the Theaetetus is to examine how the mind accounts for knowledge by seeking an answer to the question Socrates poses to Theaetetus, what is knowledge? (146A). After a few failed attempts at answering, Theaetetus posits that knowledge is true opinion (187B). Socrates responds that in order for one to know what true opinion is, he must also account for false opinion in the mind. Ultimately, while the dialogue produces no operative definition for knowledge, Plato employs this dialogue to sharpen his arguments for what are and are not the brackets of knowledge.…
