For example, if you wanted to argue that students should not be given cumulative final exams, then you would need to provide reasons for why that should be the case. Some possible reasons (i.e. premises): Studies show that cumulative exams do not adequately test what the student knows, but rather simply what the student can remember. A good test allows a student to demonstrate what they know. To the extent that cumulative final exams are meant to demonstrate a students mastery of a subject (and stand as proof of that mastery), these tests promote memorization over skills. No one defines mastery as simple recall rather, mastery involves the ability to apply knowledge in new and unexpected ways based upon knowledge of principles and method. Four premises that relate to the value and effectiveness of cumulative final exams are presented as a means of proving the conclusion that these type of final exams should not be used. Most people have a pretty strong intuitive grasp of what counts as an argument. The real sticking point, however, involves the ability to evaluate and formulate good arguments. So, the real question is this a good argument? Evaluating Arguments In order to evaluate an argument, one must be aware of some specific and important terms that involve types of arguments. Inductive arguments Arguments that follow from specific experiences to general principles. For example Every panda bear I have seen has been black and white. Therefore, all panda bears are black and white. Inductive arguments involve attempts to step up from experiences to the level of general rule.Deductive arguments Arguments that follow from general principles to specific experiences. For example All panda bears are black and white. Therefore, the panda bear at the zoo is black and white. Deductive arguments involve attempts to step down from general rules to the level of specific entities or examples.Evaluating inductive arguments Because of the nature of these arguments, one can only evaluate them as strong or weak. Strong inductive argument conclusion based upon many experiences, with little or no variation. Ex. In the argument above, it would be a strong argument if I had seen thousands of panda bears over many years, and perhaps even set about systematically studying them. Weak inductive argument conclusion based upon few experiences, with wide variation. Ex. I have only seen one or two pandas in my life.Evaluating Deductive arguments Because of the nature of these arguments, one can evaluate them as in/valid, and un/sound. Validity refers to whether the conclusion follows from the premises. The above example is valid because, assuming the premise is true, the conclusion necessarily follows. Consider the following argument: All pandas are pink and purple, therefore the panda at the zoo is pink and purple. Is this argument valid? Yes, because the proper conditions apply assuming true, does it follow. Validity is a formal distinction, attending to its form, not its truth value. Soundness, on the other hand, deals with truth value. A sound argument has all true premises thus, the first example is a sound argument, whereas the second isnt.Real world applications: Inductive arguments are commonly found in scientific study and also in dorm room chatter. Sample size, likely bias, and source are important factors for consideration.Real world applications: Most arguments you will write will likely follow some deductive pattern, where you attempt to establish true premises which necessarily lead to a conclusion.True or False: The following argument is a deductive argument. "Suppose that justice is the harmonious state of the soul. Because anger is not a harmonious state of the soul, then anger is not a just emotion." The following argument is an inductive argument. "It is a fact that Augustine, Aquinas, Descartes, and Pascal believed in God, and they were philosophers. Therefore, all philosophers probably believe in God. The following deductive argument is valid. "Because philosophy is critical thinking about principles of right thought and right ation, it follows that dogmatic thinking is unphilosophical thought because dogmatic thinking is uncritical thinking." The following argument is a sound deductive argument. "Either space and time are absolute or relative. Einstein has argued persuasively that space and time are not absolute. Therefore, space and time are relative." Choose the correct answer for the following Is the following argument (a) deductive or (b) inductive? All the students in this class are county residents, and all county residents get a tuition discount. Therefore, all the students in this class are getting a tuition discount. Is the following argument (a) deductive or (b) inductive? Every time Prof. Mulder gave a quiz last semester, he wore a tie. Therefore, I expect him to wear a tie Thursday, because he is giving a quiz on Thursday. Is the following deductive argument (a) valid or (b) invalid? Christmas is always on a Thursday. Therefore, the day after Christmas is always a Friday. Is the following inductive argument (a) strong or (b) weak? The Cambridge Dictionary of Philosophy says that William James was born in New York City in 1842. Therefore, William James was born in New York City in 1842. Pleasantville is two miles from Bean Town. Bean Town is two miles from Capital City. It follows necessarily that Pleasantville is four miles from Capital City. Deductive; valid Deductive; invalid Inductive; strong Inductive; weak Is the following argument (a) deductive or (b) inductive? Anne is either in her office or teaching in the classroom, but shes not in her classroom. Therefore, shes in her office. Is the following argument (a) deductive or (b) inductive? The Encyclopedia of Philosophy states that Bertrand Russell was a famous English philosopher. Therefore, Russell was a philosopher. Types of argument (a reminder): Inductive going from specific experiences to a general rule (concluding that certain experiences generate a rule of thumb or idea that should be followed); premises will include specific examples Deductive going from a general rule to a specific application (concluding that a specific thing should be done in a specific case); premises will include some general principle Types of arguing (forms of argument used to generate support for the conclusion): Analogy arguing that the issue at hand is very similar to an issue that is less controversial (can involve comparison and contrast) e.g. buying a new television is like volunteering to have your brains sucked out of your head. Definition carefully defining controversial terms in the hopes of at least explaining how it is being used in the specific context of the argument e.g. terrorism is defined as threatening the health and well-being of an innocent group of people as a means of affecting political change Hypothetical example creating a fictitious, but possible, case that extends the application of a rule and helps explain the ways the author intends to apply it (related to argument from analogy). e.g. imagine, for instance, that there was an extraterrestrial in the class. Wouldnt you shoot it if it even looked like it was threatening you? After all, who knows what its thinking? The same goes for bears that might enter your campsite. Factual support citing studies or numbers that lend credibility to the argument (can involve validation of cause/effect relationships) e.g. according to a study published in the Journal of the American Medical Association, fad diets like Atkins lead to long term liver and kidney damage (34). Appeals to authorities citing arguments made by other people in an effort to bolster own account e.g. as Thomas Jefferson notes, an informed populace is vital to any democracy (113). Preemptive critique bringing up likely objections to current argument and then responding e.g. people might object to the TV media being responsible for educating people about the issues. After all, so the argument goes, the media is a business that responds to market demand. This argument, however, ignores the fact that stations were granted the use of public airwaves, for free, on the condition that they devote some programming to the public good. All of these types of argument can be combined and used in various ways, but they represent means of supporting an argument. Also remember, as we looked at earlier, that certain means of arguing can be problematic (i.e. people may commit fallacies). For example, while people may try to use analogies to prove their case, you have to evaluate whether the analogy holds. The same goes for the strength of the inductive argument, the validity of the source and authority, and the usefulness of the definition. You need to be able to identify these forms of argument, even as you begin to think about using them yourself. For the argument that you brought in, first locate the conclusion that the author attempts to put forward. Is the conclusion reached inductively or deductively? Then, list the major premises that the author uses to support his/her argument, and use the list above to identify the type of support the premise is offering. Finally, I want you to evaluate the strength of the premise (is it a fallacy or not)? Continue list on separate piece of paper. Conclusion (write here in own words): Inductive or Deductive? Explain. Premise 1 Content: Type: Strength: Premise 2 Content: Type: Strength: Logical Fallacies: Hasty generalization Governor Turner is prejudiced against Catholics. During his first week in office, he appointed three people all Protestants. False Cause There are more churches in NYC than in any other city in the nation, and more crimes are committed in NYC than anywhere else. So, if we are to eliminate crime, we must abolish the churches. False Dichotomy Either I continue smoking, or Ill get so fat and anxious that youll hate me. Ad hominem Pearsons argument in favor of the theory of evolution should be discounted. Pearson is a cocaine-snorting sex pervert and, according to some reports, a member of the Communist Party. Straw man Fred says that the government taxes the average citizen too much. Fred wants to abolish government altogether, obviously. Without government, however, there would be no law and order. Freds argument is absurd. Begging the question Professors are highly intelligent people, because if they werent highly intelligent, they wouldnt be professors. Weak analogy No one would buy a pair of shoes without trying them on. Why should anyone expect to get married without premarital sex? Slippery slope If I give my money to this one panhandler, pretty soon the street will be full of them, and Ill have to give them all money and then no one will want to work and I will be broke. I must keep my money.
