First Paper Topic When someone thinks of the word knowledge, the first thing that tends to pop into their head is that they know something. The question is, do they really know something to the fullest or do they only know a part of it? There is really no correct answer to this because we do not know how much one person knows, and what information they have. In fact, there is much more to knowledge than someone would assume. There are necessary and sufficient conditions for a person to know something, and the three things that embody the concept of knowledge are truth, belief, and justification. It is important to understand how crucial truth, belief, and justification are for any …show more content…

That is where the justification part comes into play. Justification is where the person has valid reason/s in believing that the something is true. A clear coat is by using the variables m and n where m is the person and n is the something. Through the concept of knowledge, m believes that n is true, and m has justification to believe that n is indeed true. Yet, the True-justified-belief theory of knowledge does not work alone, it includes necessary and sufficient conditions. A necessary condition is important because it is an essential condition in any case. A clear example is that Y is a necessary condition for Z, and Z needs to have Y at all times. An example without variables is, having three sides is necessary in order to be a triangle. Sometimes, necessary conditions can get a little tricky because Y may not be a necessary condition of Z. It is not necessary for a person to be American to live in the United States of America, since many people from around the world come to live here. Looking into sufficient conditions, Y guarantees the presence of Z because if Y is present than Z is present. Going back to the triangle example used previously, one could state that being a triangle is sufficient for having three sides. There are in fact counter examples that show that Y may not …show more content…

Although, an American philosopher named Edmund Gettier challenged the TBJ theory. Gettier used two counterexamples where people has a justified true belief for a certain claim, but they still failed to know it. For example, a person is a huge fan of Niall Horan, a famous singer, who is from Ireland. That person goes to his hometown in Ireland thinking they will run into him. A blonde haired, young, Irish man walks out of a pub in the near distance, and the person suddenly assumes the man is Niall Horan since they are in his hometown, and he looks like him. The belief that instantly occurs is that the person just saw Niall in his hometown. Yet, the man gets into somebody’s car and drives off. However, the person is not close enough to see that the man who walked out of the pub was not Niall, but the car he goes into was Niall’s car and Niall was indeed driving concluding he was in his hometown. Therefore, there is no evidence to prove Niall is in his hometown, and what has been see by the human eye is a person who looked like Niall, but was in fact not him. There is true-justified-belief that Niall is in Ireland, but that belief is not knowledge. This proves that sometimes people believe they know something and have justification to believe something, but then something so small can alter what they think they know and end up being

There is much belief to suggest that we can depend on our senses unless there is just cause or evidence suggested to question their reliability. Therefore, the belief of reality may be subjected to interpretation or skepticism, but without solid evidence to discard what we believe to be true, we should be confident in what we hold to be true. Skepticism or Justified True Belief

There is no way to know everything there is to know. This means that knowledge will always be inherently limited by numerous different factors. According to DesCartes, knowing can only be applied to what one has clearly observed to be true (111). Observable knowledge can be limited by things such as background and sex. However, the greatest limitation may be lack of skepticism, whether it be questioning oneself or an authority.

Prior to presenting his first case, Gettier makes two explicit assumptions. First, he assumes that it is possible to be justified in believing a proposition that is in fact false. Second, he assumes that if a person is justified in believing a proposition, and recognizes that the proposition entails a second proposition, then the person is justified in believing the second proposition. What role do these two assumptions play in Gettier’s argument against the justified true belief analysis of knowledge? What do you think of these two assumptions?

The kangaroo did not believe Horton due to the fact that she only trusts her senses. The kangaroo did not believe that Horton was telling the truth because she could not see nor hear the tiny people on the speck of dust. The kangaroo follows the same approach as Lock with the knowledge of the external world. Locke is a theory of knowledge through the five senses “Locke himself, however, emphasizes that knowledge of the external world is neither based on inference or reasoning nor is it based on reflecting on ideas somehow already in the mind. Instead, it is achieved through sensory experience”(Priselac 2016).

Clifford argues that all beliefs must be justified. In his writing, The Ethics of Belief, Clifford states that “it is wrong always, everywhere, and for anyone, to believe in anything upon insufficient evidence” (Clifford 5). Clifford means that it is morally wrong to believe something without sufficient evidence. This can be a problem when one examines the very definition of belief. A belief is a thought, which may have a foundation in reality, but does not require it.

In the 1963 philosophy paper titled “Is Justified True Belief Knowledge?”, Edmund Gettier attempts to deconstruct and disprove the philosophical argument that justified true belief is knowledge. Justified true belief, also commonly referred to as JTB, is used as a certain set of conditions that are used to explain someone s knowing some sort of proposition p. More specifically, JTB is used to say that s has knowledge of p if and only if p is true, s believes that p is true, and s is justified in believing that p is true. Gettier offers main points as the conclusion of his argument against this claim. First, he states that s can be justified in believing that p is true while p is actually false.

“It is always by favour of Nature that one knows something” -Wittgenstein (1975) Edmund Gettier questioned the accepted and existing notion of propositional knowledge which was defined as Justified True Belief (JTB). According to justified true belief, for a premise (p) can be considered knowledge (K), if and only if the individual has belief in the premise (Bp), believes the premise to be true (Tp) and is supported by justification (has enough evidence to believe that p is true (Jp). So, Kp↔ Bp +Tp + Jp Gettier, through the use of two cases, proves that the existence of justified true belief does not guarantee knowledge. In other words, that justified true belief is not a

Clifford then says that we must judge people’s actions that their beliefs fuel (par. 6). Next, Clifford goes on to say that every belief someone holds is important as it affirms other beliefs and it influences a person’s actions regardless when the action might happen (par. 8). Clifford also explains that every man’s belief affects every other person (par. 9). Clifford states that humans want to believe we know the truth because we find comfort in it and that we are afraid of being wrong because we feel powerless (par. 13).

Belief is accepting a given position or proposition as true even when one does not have enough evidence to back up his or her belief. While having doubt is a feeling of uncertainty or lack of conviction. In “The Fixation of Belief”, Charles Sanders Peirce discusses logic, reason, knowledge, and how one believes. Peirce explains what does it mean to believe or to doubt something and how one can distinguish between what is true and what is not. Peirce also explains four methods of establishing belief, which are the method of tenacity, authority, priori and science.

Clifford believes you need enough evidence to believe in something because belief is a false sense of hope that causes doubtful actions which could cause a spiral of projected situations that can lead to either good or bad outcomes. These outcomes could have officially been avoided if such “belief” never existed and the first projection was actually proved. I believe he is right because without solid evidence, a belief could cause a domino effect of situations which could easily been avoided. It is just unreasonable to have a belief and not have confirmation to back it up. Obviously it would require some serious energy to really evaluate these cases, but in the end of the day you will have

In some situations, true beliefs are vital, especially if they are shared. In others, belief does not have to be true for everyone, but need only be true for an individual. A belief that needs to be true is usually a belief pertaining to shared knowledge. If physicists are examining electric field strength using Coulomb’s law, the belief that the charge on an electron is -1.6 x 10-19 Coulombs, must be true, or the results will not pan out.
