Are Computers Really Intelligent?

Are Computers Really Intelligent? Are computers really intelligent? Computer Intelligence has been in hot debate since the 1950’s when Alan Turing invented the Turing Test. The argument over the years has taken two forms: strong AI versus weak AI:. That is, strong AI hypothesises that some forms of artificial intelligence can truly reason and solve problems, with computers having an element of self-awareness, but not necessarily exhibiting human-like thought processes. (http://en.wikipedia.org/wiki/Strong_AI). While Weak AI argues that computers can only appear to think and are not actually conscious in the same way as human brains are. (http://www.philosophyonline.co.uk/pom/pom_functionalism_AI.htm). These areas of thinking cause fundamental questions to arise, such as: ‘Can a man-made artefact be conscious?’ and ‘What constitutes consciousness?’ Turing’s 1948 and 1950 papers followed the construction of universal logical computing machines, introducing the prospect that computers could be programmed to execute tasks which would be called intelligent when performed by humans.(Warner 1994: 118). Turing’s idea was to create an imitation-game on which to base the concept of a computer having its own intelligence. A man(A), and a woman (B), are separated from an interrogator, who has to decipher who is the man and who is the woman. As objective is to trick the interrogator, while B tries to help the interrogator in discovering the identities of the other two players.(Goldkind, 1987: 4). Turing asks the question: What will happen when a machine takes the part of A in this game? Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman?’ (Quoted from Goldkind 1987: 4). Turing’s test offered a simple means test for computer intelligence; one that neatly avoided dealing with the mind-body problem. (Millican, P.J.R., 1996: 11). The fact that Turings test did not introduce variables and was conducted in a controlled environment were just some of its shortfalls. Robert French, in his evaluation of the test in 1996, stated the following: ‘The philosophical claim translates elegantly into an operational definition of intelligence: whatever acts sufficiently intelligent is intelligent.’ However, as he perceived, the test failed to explore the fundamental areas of human cognition, and could be passed ‘only by things that have experienced the world as we have experienced it.’ He thus concluded that ‘the Test provides a guarantee not of intelligence but of culturally-oriented human intelligence.’ (Ibid : 12). Turing postulated that a machine would one day be created to pass his test and would thus be considered intelligent. However, as years of research have explored the complexities of the human brain, the pioneer scientists who promoted the idea of the ‘electronic brain’ have had to re-scale their ideals to create machines which assist human activity rather than challenge or equal our intelligence. John Searle, in his 1980 Chinese Room experiment argued that a computer could not be attributed with the intelligence of a human brain as the processes were too different. In an interview he describes his original experiment: Just imagine that youre the computer, and youre carrying out the steps in a program for something you dont understand. I dont understand Chinese, so I imagine Im locked in a room shuffling Chinese symbols according to a computer program, and I can give the right answers to the right questions in Chinese, but all the same, I dont understand Chinese. All Im doing is shuffling symbols. And now, and this is the crucial point: if I dont understand Chinese on the basis of implementing the program for understanding Chinese, then neither does any other digital computer on that basis because no computers got anything I dont have. (Free Inquiry 1998: 39). John Searle does not believe that consciousness can be reproduced to an equivalent of the human capacity. Instead, it is the biological processes which are responsible for our unique make-up. He says that ‘consciousness is a biological phenomenon like any other and ultimately our understanding out it is most likely to come through biological investigation’ (Searle, 1990 :58-59. Quoted from McCarthy, 2001, http://www-formal.stanford.edu/jmc/’). Considered this way it is indeed far fetched to think that the product of millions of years of biological adaptation can be equalled by the product of a few decades of human thinking. John McCarthy, Professor Emeritus of Computer Science at Stanford University advocates the potential for computational systems to reproduce a state of consciousness, viewing the latter as an ‘abstract phenomenon, currently best realized in biology,’ but arguing that consciousness can be realised by ‘causal systems of the righ t structure.’ (McCarthy, 2001, http://www-formal.stanford.edu/jmc/ ) The famous defeat of Garry Kasparov, the world chess champion, in 1997 by IBMs computer, Deep Blue, promoted a flurry of debate about whether Deep Blue could be considered as intelligent. When asked for his opinion, Herbert Simon, a Carnegie Mellon psychology professor who helped originate the fields of AI and computer chess in the 1950s, said it depended on the definition of intelligence used. AI uses two definitions for intelligence: What are the tasks, which when done by humans, lead us to impute intelligence? and What are the processes humans use to act intelligently? Measured against the first definition, Simon says, Deep Blue certainly is intelligent. (http://whyfiles.org/040chess/main3.html). According to the second definition he claims it partly qualifies.(Ibid). The trouble with the latter definition of intelligence is that scientists don’t as yet know exactly what mechanisms constitute consciousness. John McCarthy, Emeritus professor at Stanford University explains that intelligence is the ‘computational part of the ability to attain goals in the world.’ He emphasises that problems in AI arise as ‘we cannot yet characterise in general what computational procedures we want to call intelligent.’ (McCarthy 2003: 3). To date, computers can perform a good understanding of specific mechanisms through the running of certain programs; what McCarthy deems ‘somewhat intelligent.’ (McCarthy 2004: 3). Computing language has made leaps and bounds during the last century, from the first machine code to mnemonic ’words’ In the 90’s the so-called high-level languages were the type used for programming, with Fortran being the first compiler language. Considering the rapid progress of computer technology since it first began over a hundred years ago, it is likely that unforeseeable developments will occur over the next decade. A simulation of the human imagination might go a long way to convincing people of computer intelligence. However, many believe that it is unlikely that a machine will ever equal the intelligence of the being who created it. Arguably it is the way that computers process information and the speed with which they do it that constitutes its intelligence, thus causing computer performance to appear more impressive than it really is. Programs trace pathways at an amazing rate for example, each move in a game of chess, or each section of a maze can be completed almost instantly. Yet the relatively simple process of trying each potential path fails to impress once it’s realised. (Reed, 2003: 09). Thus, the intelligence is not in the computer, but in the program. For practical purposes, and certainly in the business world, the answer seems to be that if it seems to be intelligent, it doesnt matter whether it really is. (Reed 2003: 09). However, computational research will have a difficult task to explore simulation of, or emulation of, the areas of human cognition. Research continues into the relationship between the mathematical descriptions of human thought and computer thought, hoping to create an identical form.(Wagman, M., 1991: 2). Yet the limits of computer intelligence are still very much at the surface of the technology. In contrast, the flexibility of the human imagination that creates the computer can have little or no limitations. What does this mean for computer intelligence? It means that scientists need to go beyond the mechanisms of the human psyche, and perhaps beyond programming, if they are to identify a type of machine consciousness that would correlate with that of a human..

The Ontology of Many-Worlds: Modality and Time Essays -- Compare Contr

The Ontology of Many-Worlds: Modality and Time ABSTRACT: There are two types of theories regarding many worlds: one is modal, while the other is temporal. The former regards reality as consisting of many possible worlds, while the latter holds that reality consists of many momentary worlds, which are usually called moments. I compare these two theories, paying close attention to the concept of transworld identity and compare trans-possible world identity with trans-momentary world identity (or transmoment identity). I characterize time from the point of many-worlds view, believing this to be one of the best ways of grasping the reality of time. First, I show that there is reason to adopt the many-worlds view because transworld identity is meaningful for both of them, while it is not for space. Second, I argue that transmoment identity is different from transpossible world identity concerning reality. The former is a realistic relation, while the latter is not. Thus, I find that the reality of time is in the relation of transmomen t identity. Such a view, I contend, has merit on the basis that it recognizes the reality of time in a sense that is not true of space. Introduction There are two kinds of theories of many-worlds; the one is modal and the other temporal. The former regards the reality as consisting of many possible worlds, while the latter as consisting of many momentary worlds, which usually are called 'moments'. (1) In this paper I make a comparison between modal and temporal theories of many-worlds, especially paying attention to the concept of transworld identity and so making a comparison between trans-possible-world identity and trans-momentary-world identity (or trans-moment identity abbreviately). (2... ... for the present argument. (5) Kaplan's theory of direct reference does not necessarily presuppose the ontology of many-worlds. So my critcism is not directed for his theory itself but for its application to the ontological explanation of trans-moment identity.

Abraham Lincoln: Issued the Emancipation Proclamation Essay

Many may say eh made things worse, but i beg to argue. Abraham Lincoln is the reason for the civil war people say, but look where it got us! The union won, and the slaves are free. During the Civil war (1861-1865) many actions occurred. When Lincoln was elected President in 1861 South Carolina seceded followed by 6 other sates, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas. Four other states threatened to secede as well. Then a month after the 7 seceded they formed a Government. Later on March 4th when Lincoln was elected he said that he didn’t want to take away slavery from the states that already had slavery existing and common in their state. He also said that he would not deal or except secession either. Fort Sumter started the Civil war. See more: Is the Importance of being earnest a satirical play essay Lincoln was sending supplies to Fort Sumter and told them before hand so they would be aware. When they got there South Carolina feared a trick, so they said they would take the supplies then surrender, but his offer was not taken, and thats when the first shot was fired. April 12, 1861 the Civil War had begun. On January 27th, 1862 Lincoln allowed the Union to launch unified aggressive action against the Confederacy. January 1863 Lincoln issued the Emancipation Proclamation that freed the slaves in the states that were still in rebellion on January 1st 1863. The Gettysburg Battlefield was dedicated as a national cemetery, this was a huge war. Over 54 thousand soldiers were killed. The south wasn’t strong enough, and the North succeeded. On April 7th 1865 General Grant called upon General Lee to surrender. Lee sent home his troops and the Civil War ended. Many battles were fought and the Union won over the Confederate. On April 14th President Abraham Lincoln was assassinated by John Wilkes Booth. John was obsessed with avenging the Confederate defeat.

Public Health Campaign For Fight Hiv / Aids - 864 Words

Core question: Imagine you are a fledgling medical anthropologist in Africa. What are the key points in your public health campaign to fight HIV/AIDS? HIV is a virus that causes the disease of AIDS that damages your immune system. HIV is manageable, but cannot be cured. There are many ways to prevent HIV from happening. Some of the ways to prevent HIV is to be tested, being tested is the safest way not to transmit the virus and it can prevent infection to others. Another way is to get educated, getting involved in programs that teaches about HIV/AIDS can educate people to prevent it. 1. Think back to the information we covered last week on ethnocentrism. How does our understanding of HIV/AIDS in Africa tend to be ethnocentric? [5 pts.] Many ethnocentric people tend to believe that Africans are HIV positive because of the way that they are living. Some might think that Africans have most HIV because of their race, and they might think that they are rapist, also they might think of the many off and on relationships. This is a wrong way of thinking because these ethnocentric people are not educated about African culture, Africans are sometimes born with the disease and they are poor and cannot treat there disease. 2.
