Hilary Putnams 'Brains In A Vat': An Analysis

In Hilary Putnam's "Brains in a Vat" theory, he argues against ontological, external-world skepticism. However, his arguments seem very unconvincing in some places. In this paper I will go over Putnam's "Brains in a Vat" theory and then I will specify where I think Putnam's arguments are not sufficient enough to satisfy myself.
Before I present my criticism, I will briefly summarize Putnam's argument. Consider an ant crawling on a beach that accidentally outlines a picture of Winston Churchill. Many people would not claim that the ant purposely referred to Churchill. Despite the ants resembled drawing, it does not resemble or refer to Churchill.(Page 397, paragraph 2, "Brains in a Vat" Hilary Putnam) Putnam states that "nothing physical has …show more content…
Putnam admits that his whole "Brains in a Vat" theory is quite absurd(page 400, paragraph 1, Hilary Putnam), then it is also very conceivable to assume that we could articulate direct reference to some kind of input that is feeding a sophisticated vat. If the external "beings" that are responsible for the vats are supposedly highly sophisticated and advanced, then it is acceptable to claim that a whole set of references could have easily been constructed specifically for these vats. Its undeniable that these external sophisticated vat-creators could have the capability to send forth such references to brains in vats. A brain in a vats inadequate references may not be physically direct, but it still gives way to a whole other world of references that we can think and be skeptical from. If these brains have the ability to discuss their world with other brains in vats(page 400, paragraph 2, Hilary Putnam), then it is indubitable that the evatted brains can be skeptical of their

    Robert A. Ferguson's The Commonalities Of Common Sense

    In 1776 aspirations of obtaining independence and freedom weighed heavily on the hearts of numerous Europeans living in North America. Many of the European Americans aspired to live by their own accord in a sovereign nation; however, there were other European Americans who wanted North America to be governed by the British. The European Americans who desired to revolt and overthrow the tyrannical rule of Great Britain in North America knew that they needed to gain as many supporters as they could in order to have a chance against the highly touted British army. They realized that the only way to gain more supporters was to convince the adamant British loyalists to join their fight for freedom. They began to flood North America with numerous…

    Hilary Putnam's Essay 'Brains In A Vat'

    In Hilary Putnam’s essay “Brains in a Vat”, he begins by mentioning an illustration of an ant making markings in the sand and how these markings depict Winston Churchill. He then goes on to mention whether or not one can consider that it is Churchill because the ant had no intention of replicating Churchill as it does not even know who he is (Putnam, 1981:1).”The argument is simple; what we said about the ant’s curve applies to any physical object. No physical object can, in itself, refer to one thing rather than to another; nevertheless, thoughts in the mind obviously do succeed in referring to one thing rather than another.” (ibid.:2) This shows that the significance of mentioning the ant in the sand is to show the relation between representations…

    How Does Andrew Jackson Manipulate The Constitution

    Andrew Jackson believed that our freedoms under the Constitution would be protected if we, the Americans, did not let the federal government get to big and overstep their boundaries. For instance, Jackson said that we need to put a stop the effort to “induce” the general government to exceed their power of taxing people, because if not these high taxes could place unnecessary burdens on people who were already struggling. Mainly, pointing out the agricultural and your laboring classes (pg. 208). Jackson also stated that even though we want to “enlarge” the general government, we are also giving them the power to overstep their boundaries; boundaries that were clearly listed in the Constitution (pg. 208). He believed that if the government did try to overstep their boundaries it would lead to a domino effect.…

    Public Thinking: Smarter Than You Think By Clive Thompson

    Have you ever wondered how technology can help increase the clarity of your writing? In the chapter, Public Thinking in the book Smarter Than You Think by Clive Thompson was published in 2013. Thompson is a well- known Canadian journalist, blogger, and technology writer. Being born 1968, it is ironic how he supports the use of technology rather than trying to convince his audience the downside of it. Through being a journalist, blogger, and technology writer, we can determine that Thompson is promoting the use of technology and how it influences better writing through public thinking.…

    Clifford's Argumentative Analysis

    Clifford and James are two philosophers who have contradicting opinions on whether having sufficient evidence is always necessary to believe in something. Where Clifford believes you cannot believe in anything without sufficient evidence, James believes that if the evidence doesn’t point in one way or another, it is justified to believe something based on our will. I will be arguing that James’ side is indeed correct. In James’ paper, he provides concrete evidence as to why his opinion is correct.…

    Haidt And Lukianoff's The Coddling Of The American Mind

    University students who insist on censorship by a college administration when a topic, issue or idea causes them emotional distress, effectively denies all who participate in the academic setting the basic right of freedom of speech in a venue that should be open to free exchanges of ideas. To take away topics that give them emotional stress, students have come up with a solution to the issue, trigger warnings. According to Jonathan Haidt and Greg Lukianoff’s The Coddling of the American Mind, trigger warnings are alerts for professors to give their students if trauma-trigging material is going to be taught (Haidt and Lukianoff 44). These trigger warnings fall under the category microagressions.…

    Real Self Deception Summary

    After some time, I realize that Mele 's ideas made more sense than some of Gendler 's ideas; however, I was intentionally deceiving myself by contrasting both sets of ideas and forcibly trying to make Gendler 's set to make more sense because I didn 't want to be mistaken. At this point, I realized that self-deception is, in fact, a crucial part of our life that we don’t really think about. Moreover, even though I read both articles and I think they have intelligible ideas, I believe that both articles are trying to encircle a massively broad, even infinite, number of possible cases with what seems to me as finite closed systems. In this paper, using references only from the two stated articles, I will attempt to give a definition for belief and an idea of how the two stated thoughts could merge…

All of his arguments are supported with premises spoken through the philosophers in his book (this esay on Cleanthes’s argument).

These machines, both human and natural, all have a mans of working towards a common end.…

    Louis H. Sullivan's Thoughts: The Power Of The Human Mind

    The human mind is a fascinating machine. While humans may not be the biggest or strongest throughout the animal kingdom, our thoughts, and as a result, our intellectual power has lead us to become the dominating figure on this planet. Many people argue that one’s most powerful resource is their thoughts, but what kind of “thoughts” make them so fierce? Louis H. Sullivan, in his essay “Thoughts”, believes that creative thinking is the most powerful method of thinking. In order for one to think creatively, they must not use words, as words slow down the thought process due to having to find words and group them together which can be tedious.…

    Mark Edmundson On The Uses Of Liberal Education Analysis

    “On the Uses of Liberal Education: As Lite Entertainment for Bored College Students”, was written by Mark Edmundson in 1973. Edmundson conveys his ideas in an authoritative, straightforward manner although his writing is somewhat muddled. His arguments are clear but I had a hard time understanding his writing because he states his arguments after giving an example of what he is claiming. This makes his writing long and drawn out. I had to read and re-read his essay to understand his arguments.…

    Stephen G. Pott's Nine Consequences

    Stephen G. Potts, author, writes his article “Looking for the Exit Door: Killing and Caring in Modern Medicine” to show his readers the nine consequences that he believes will arise if euthanasia is institutionalized, or legal, in the United States. Potts’ style of writing is different most other philosophical writers in the sense that he backs up his opinion on euthanasia by explaining his nine consequences and further elaborating them by examining scenarios that are applicable to the real world. From reading Potts’ article it is easy to understand from a legality standpoint Potts believes that his nine bad consequences are bad enough to outweigh any good that may come from euthanasia, so it should not be institutionalized. Before reading this article I was a firm believer that euthanasia should absolutely be institutionalized, however, after reading and dissecting all of Potts’ many good points I began to question whether or not euthanasia really is beneficial. After careful thought and consideration, I would have to disagree with Potts’ simply because his consequences are too easily argued and even potentially pointless.…

    Analysis Of Thought By Louis H. Sullivan

    In his essay “Thought,” Louis H. Sullivan greatly stresses the importance of thinking critically and creatively, and presents the argument that one must think not in words but rather in images, rhythm, and other wordless forms of communication. Sullivan resorts heavily on comparisons and analogies and metaphors to convey the impractical usage of words. “But in passing I may say that real thinking is better done without words than with them, and creative thinking must be done without words,” Sullivan argues, and he goes on to explain the intellectual heft and rigor of thinking creatively and highlights its rewards. Sullivan also asserts that one must think in the present and the present alone, for his reasoning is that “you cannot in the past,…

    Descartes And Berkeley: The Nature Of Sensible Objects

    In their writings, Descartes and Berkeley argue the nature of sensible objects. Sensible objects are what are perceivable to the mind. The nature of how these objects are perceived and if, what the mind perceives exists is the foundation of both Descartes and Berkeley’s arguments. Are sensible objects distinctly external matter that are perceived by the mind, or are they created within the distinct mind and perceived directly. The arguments are related to Descartes and Berkeley’s different stances on rationalism and empiricism, or if our minds identify knowledge of sensible objects through experience or innate knowledge.…

    Summary Of Think By Simon Blackburn

    In Simon Blackburn’s “Think”, Blackburn argues whether an all good, all knowing, and all powerful entity does exist. I focused on the argument Blackburn posed on Chapter 5, “God”. Blackburn is wrong to claim that the existence of evil suggests an entity who is all-good, all-knowing, and all-powerful does not exist. Simon Blackburn discusses that there is no actual truth to religion since there is no concrete proof that there is even a God. Blackburn brings up the fact that it is not possible for an all good, all knowing, and all powerful to exist.…
