When one states something they usually feel as if it is completely certain. Author Ludwig Wittgenstein wrote “On Certainty” which is a series of notes; the author wrote these notes towards the end of his life. The series is about matters related to knowledge, doubt, and skepticism. Even though Wittgenstein notes were not organized, certain themes and preoccupations were present. He is usually addressed as one of the most misunderstood philosophers in history. Due to his method of philosophy, he was able to see life very different. Attacking methods other philosophers’ used such as the proposition and blatantly exposed them as senseless or even nonsense. According to him a proposition has no meaning unless placed within a particular context. Through these notes one could discuss the context of human understanding and problems concerning all claims to certainty.
In order to understand Wittgenstein “On certainty” one must first start out in a matter of understanding who Wittgenstein is addressing. The series of notes starts out as a response to G.E. Moore, an author who wrote the “A Proof of the External World’. Wittgenstein notes were brought to light through Moore’s essay which discussed anti-skepticism and anti-idealist. Moore’s paper attempts to prove that there is an external world pertaining to our senses. He then states he had already shown this existence by holding up his hand “Here is a hand”. Moore then uses the example of his hand to validate boldly why anyone would every question such a reasonable claim. Wittgenstein does seem to admire Moore’s claim that he has a hand; however Wittgenstein uses the idea that any claim that an individual thinks they know can be doubted. More ever you might say that he is challenging M...

...pposed to express just my subjective certainty, I must be able to satisfy myself that I am right. But I can't do that, for my having two hands is not less certain before I have looked at them than afterwards. But I could say: "That I have two hands is an irreversible belief." That would express the fact that I am not ready to let anything count as a disproof of this proposition” (Wittgenstein).
One question that arises is vital and it is do we become more secure in our certainty approaching death or less. Judging from his notes during the final days individuals start to challenge and question human understanding. Soon promoting open discussion on even the most trivial questions.
In result Wittgenstein purpose of his notes was to challenge other philosophers and bring new concepts to light. Through this one can start to doubt and not claim to know but be certain.
The thesis of the Epilogue comes from an unorthodox definition of faith and belief. Belief in the Cartesian World refers to something that has been proven beyond a reasonable doubt. The key term in this definition
a new system of knowledge that is free of prior prejudices for establishing the truth of
Knowledge, its source and truthfulness have been under question for a long time. People have always wondered what exactly constitutes facts and if there are any defining laws that can be attributed to all knowledge or information available in the world. Many philosophers speculated on how information can be interpreted according to its falsity or truthfulness, but have not come to definite conclusions. Edmund Gettier has provided one of the key pieces in understanding and trying to figure out what knowledge really is.
Descartes’ theory of systematic doubt centered on his belief that individuals cannot trust their perceptions of the external world because sensory stimuli do not necessarily reflect true depictions of the world. Throughout his life, Descartes assumed information being received through his senses to be accurate representations of the external world until he realized that the senses as a source for information can occasionally mislead both himself and all other people. With this knowledge in mind, Descartes knew that an absolute confidence in sensory perception could deceive individuals about the external world and lead to a challenging of beliefs. As an example of this, Descartes considered that, as he wrote this meditation on systematic doubt,
It is also important to realize that our mind doubts things because it knows its own limits. Thus since we know nothing to be certain it is important to use softening phrases such as “perhaps, somewhat, some, they say, I think, and so on (356)”. Montaigne was constantly amazed at how much knowledge we claimed to be sure of.
In Stephen Jay Gould’s essay, “Some close encounters of a mental kind,” Gould discussed about how certainty can be both blessing and dangerous. According to Gould, certainty can be blessing because it can provide warmth, comfort and secure. However, it can also be a danger because it can trick our mind with false information of what we see and remember in our mind. Gould also talked about the three levels of possible error in direct visual observation: misperception, retention and retrieval. According to Gould, our human mind is the greatest miracle of nature and the wicked of all frauds and tricksters mixed. To support his argument and statements, he used an example of an experiment that Elizabeth Loftus, a professor from University of California Irvine, did to her students and a personal experience of his childhood trip to the Devils Tower. I agree with Gould that sight and memory do not provide certainty because what we remember is not always true, our mind can be tricky and trick us into believing what we see/hear is real due to the three potential error of visual observation. Certainty is unreliable and tricky.
substantial knowledge. “Can reason give us substantial knowledge of anything, or is all a priori knowledge analytic and therefore trivial.” In examining knowledge, the general consensus by philosophers and theorists is that true belief is a necessary condition for knowledge, and it was once thought that justification, when added to true belief, yields a necessary and sufficient condition for knowledge. Its sufficiency however, was disproved by Edmund Gettier.
“I will doubt everything that can possibly be doubted, and if anything is left, then it will be absolutely certain. Then I will consider what it is about this certainty (if there is
Knowledge can be a great attainment but an excess of it can lead to doubt. Doubt forms because we tend to rely on our feelings to decide what is real and what is not, but why is that wrong? It’s simple, our feelings are not absolute. Although, everything we know we base off of our emotions and interactions with an object so why question it? We question our feelings because we cannot be sure if they are true or not. We try to justify them with claims so the feelings can be proven. Since our feelings fail to eliminate the doubt set in our minds because they are limited and undependable, we turn to reason through ideas to comprehend our thoughts. We become so unsure due to the factors that come into play when making a decision. Doubt can cause strong minds to flutter therefore making us question the credibility of our feelings. Allowing doubt to seep through, leads to a never ending battle of thoughts. Can I really trust my feelings? As you begin to reflect on your attitude towards the subject, you start to make assumptions about other’s attitudes on the subject. This reflection deepens the doubt in your once firm comprehension. Although we have reason to not doubt ourselves since we think we are right and others might also agree, it still does not answer the question of how do we know that that certain object is reality and who...
Skepticism is the view that there is no way to prove that objects exist outside of us. Skeptics hold that we can not distinguish between dreams and reality, and therefore what we take to be true can very well be creations of our minds while we are nothing more than a simple piece of matter, such as a brain sitting in a vat that is connected to a machine that simulates a perfect representation of reality for the “brain” to live in.1 In the excerpt “Proof of an External World” from his essay of the same name, G.E. Moore responds to the skeptic’s argument by attempting to prove the existence of external objects. There are four parts to this paper. Firstly, I will explain Moore’s overall argumentative strategy and how he considers his proof to be rigorous and legitimate. Then, I will present Moore’s proof of the existence of an external world. Thirdly, I will discuss the responses that skeptics may have to Moore’s argument and how Moore defends his proof against the these responses. Finally, I will give my opinion on how efficiently Moore defends his claims against the skeptics’ responses.

He begins by looking at the very common views of death that are held by most people in the world, and tells us that he will talk of death as the "unequivocal and permanent end to our existence" and look directly at the nature of death itself (1). The first view that
In his epistemological quest for truth, through thought experiment, Descartes’ Meditations offers the reader a method of doubt that could be used in order to discover what is absolutely certain, and free oneself from the errors caused by misjudgments. Descartes’ purpose is to find indubitable truth. He makes used of the method of hyperbolic doubt in order to establish an absolute and convincing foundation of truth. He discovers that sense experience can be put to doubt, but Descartes cannot doubt that he actually doubts. Furthermore, he fears deception about everything. However, he cannot be deceived about his own existence since to be deceived, one must first exist. “I think, therefore I am”. I...

Some of the objections, such as the ones made by Edmund Gettier, claim that three conditions are not nearly enough to justify a true belief, and that at the very least a fourth must be added. Gettier presents a very valid criticism of the JTB theory of knowledge, and his counter examples highlight flaws in the JTB theory that make it an inadequate theory of knowledge. Gettier claims takes an issue with the third part of the JTB theory, which states that proposition P must be true. Gettier makes the interesting observation that person S may very well be justified in believing in proposition P even if P is false
