inductive argument by analogy examples

By contrast, an inductive argument is one such that, if one accepts the truth of the premises, one can doubt the truth of the conclusion. inductive argument: An inductive argument is the use of collected instances of evidence of something specific to support a general conclusion. In response, it might be advised to look for the use of indicator words or phrases as clues to discerning an arguers intentions or beliefs. So, it can certainly be said that the claim expressed in the conclusion of a valid argument is already contained in the premises of the argument, since the premises entail the conclusion. Notice that, unlike intending or believing, claiming and presenting are expressible as observable behaviors. This is of course not meant to minimize the difficulties associated with evaluating arguments. Logically speaking, nothing prevents one from accepting all the foregoing consequences, no matter how strange and inelegant they may be. For example, if I know that one circle with a diameter of 2 . Logic. In a deductive logic, the premises of a valid deductive argument logically entail the conclusion, where logical entailment means that every logically possible state of affairs that makes the premises true must make the conclusion true as well. Stated differently, A deductive argument is one that would be justified by claiming that if the premises are true, they necessarily establish the truth of the conclusion (Churchill 1987). Inductive reasoning is further categorized into different types, i.e., inductive generalization, simple induction, causal inference, argument from analogy, and statistical syllogism. A similar idea is expressed by saying that whereas deductive arguments are demonstrative, inductive arguments outrun their premises (Rescher 1976). If the arguer intends or believes the argument to be one that merely makes its conclusion probable, then it is an inductive argument. Elmhurst Township: The Priestly Fraternity of St. Peter, 2012. The use of words like necessarily, or it follows that, or therefore it must be the case that could be taken to indicate that the arguer intends the argument to definitely establish its conclusion, and therefore, according to the psychological proposal being considered, one might judge it to be a deductive argument. For example, a belief such as It will rain today might be cashed out along the lines of an individuals behavior of putting on wet-weather gear or carrying an umbrella, behaviors that are empirically accessible insofar as they are available for objective observation. Estefana is a woman and has a knack for mathematics. Here are some relevant considerations: Analogical arguments occur very frequently in discussions in law, ethics and politics. Therefore, Dr. Van Cleave should not give Mary an excused absence either. If the argument is weak, cite what you think would be a relevant disanalogy. Inductive reasoning refers to arguments that persuade by citing examples that build to a conclusion. 1 - Andrs built his house without inconveniences, therefore, it is probable that he can build any house without inconveniences. Likewise, Salmon (1963) explains that in a deductive argument, if all the premises are true, the conclusion must be true, whereas in an inductive argument, if all the premises are true, the conclusion is only probably true. The two things being compared here are Bobs situation and our own. 2nd ed. For example, one cannot coherently maintain that, given the way the terms deductive argument and inductive argument are categorized here, an argument is always one or the other and never both. Induction is a method of reasoning that moves from specific instances to a general conclusion. We can refer to these as the " analogues ". It involves finding out the name of the wider category A of things that correctly . A false analogy is a faulty instance of the argument from analogy. Deductive arguments may be said to be valid or invalid, and sound or unsound. Realizing this, Bob decides not to throw the switch and the train strikes and kills the child, leaving his car unharmed. 3: Evaluating Inductive Arguments and Probabilistic and Statistical Fallacies, Introduction to Logic and Critical Thinking (van Cleave), { "3.01:_Inductive_Arguments_and_Statistical_Generalizations" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.02:_Inference_to_the_Best_Explanation_and_the_Seven_Explanatory_Virtues" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.03:_Analogical_Arguments" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.04:_Analogical_Arguments" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.05:_Probability" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.06:_The_Conjunction_Fallacy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.07:_The_Base_Rate_Fallacy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.08:_The_Small_Numbers_Fallacy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.09:_Regression_to_the_Mean_Fallacy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "3.10:_Gambler\'s_Fallacy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_Reconstructing_and_Analyzing_Arguments" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Formal_Methods_of_Evaluating_Arguments" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Evaluating_Inductive_Arguments_and_Probabilistic_and_Statistical_Fallacies" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Informal_Fallacies" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Back_Matter : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "license:ccby", "showtoc:no", "authorname:mvcleave", "argument from analogy" ], https://human.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fhuman.libretexts.org%2FBookshelves%2FPhilosophy%2FIntroduction_to_Logic_and_Critical_Thinking_(van_Cleave)%2F03%253A_Evaluating_Inductive_Arguments_and_Probabilistic_and_Statistical_Fallacies%2F3.03%253A_Analogical_Arguments, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), 3.2: Inference to the Best Explanation and the Seven Explanatory Virtues, http://www.givewell.org/giving101/Yorther-overseas, status page at https://status.libretexts.org. 18. If the argument is determined to be sound, then its conclusion is ceteris paribus worth believing. Therefore, Socrates is mortal. Therefore, Socrates eats olives. An inductive argument is one whose premises are claimed to provide only some less-than-conclusive grounds for accepting the conclusion (Copi 1978; Hurley and Watson 2018). An analogical argument is an explicit representation of a form of analogical reasoning that cites accepted similarities between two systems to support the conclusion that some further . Inductive reasoning refers to arguments that persuade by citing examples that build to a conclusion. Gabriel is already an adult and is not circumcised. Kreeft, Peter. 10. Plausible Reasoning. But those things are a bit out of the scope of this beginner's . Introduction to Philosophy: Classical and Contemporary Readings. Even if bananas and the sun appear yellow, one could not conclude that they are the same size. One day Bob parks his car and takes a walk along a set of train tracks. All of these proposals entail problems of one sort or another. For example, the rule implicit in this argument might be something like this: Random sampling of a relevant populations voting preferences one week before an election provides good grounds for predicting that elections results. By contrast, the basic distinctions between deductive and inductive arguments seem more solid, more secure; in short, more settled than those other topics. 4. Pedro attends mass regularly. The neighbors parrot imitates the sounds it hears. However, this psychological approach does place logical constraints on what else one can coherently claim. They are just too polymorphic to be represented in purely formal notation. Inductive Arguments Words like "necessary" or "it must be the case . Water is not a living being. However, upon closer analysis these other approaches fare no better than the various psychological approaches thus far considered. Question: Assignments 1. Rather, they should be informally . Example of Inductive Reasoning. If it would, one can judge the argument to be strong. Furthermore, there is no reason to suppose that it is some other type, unless it isnt really an argument at all, since no one intends or believes anything about how well it establishes its conclusion. Likewise, some arguments that look like an example of a deductive argument will have to be re-classified on this view as inductive arguments if the authors of such arguments believe that the premises provide merely good reasons to accept the conclusions as true. The Power of Critical Thinking: Effective Reasoning about Ordinary and Extraordinary Claims. Ultimately, the deductive-inductive argument distinction should be dispensed with entirely, a move which is no doubt a counterintuitive conclusion for some that nonetheless can be made plausible by attending to the arguments that follow. Moreover, a focus on argument evaluation rather than on argument classification promises to avoid the various problems associated with the categorical approaches discussed in this article. Consider the following argument: All As are Bs. Miriam Tortoledo was bitten by an Aedes aegypti mosquito. On a similar note, the same ostensible single argument may turn out to be any number of arguments if the same individual entertains different intentions or beliefs (or different degrees of intention or belief) at different times concerning how well its premises support its conclusion, as when one reflects upon an argument for some time. Inductive reasoning is much different from deductive reasoning because it is based upon probabilities rather than absolutes. 1. The consequences of accepting each proposal are then delineated, consequences that might well give one pause in thinking that the deductive-inductive argument distinction in question is satisfactory. 7. However, this tactic would be to change the subject from the question of what categorically distinguishes deductive and inductive arguments to that of the grounds for deciding whether an argument is a good one a worthwhile question to ask, to be sure, but a different question than the one being considered here. Strictly speaking, arguments, consisting of sentences lacking cognition, do not reason (recall that earlier a similar point was considered regarding the idea of arguments purporting something). In short, one does not need a categorical distinction between deductive and inductive arguments at all in order to successfully carry out argument evaluation.. Inductive reasoning involves drawing a general conclusion from specific examples. To give an analogy is to claim that two distinct things are alike or similar in some respect. What is the maximum amount of dollars that I can pass without declaring from the US to Mexico. Deductive Forms: An Elementary Logic. Analogical Arguments. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. So in general, when we make use of analogical arguments, it is important to make clear in what ways are two things supposed to be similar. They concern individuals mental states, specifically their intentions, beliefs, and/or doubts. Today during the storm, thunder was heard after the lightning. C H A P T E R 13 Inductive Reasoning f it looks like a duck, walks like a duck, and quacks like a duck, then it's a duck. Evaluating arguments can be quite difficult. Paul Edwards. If the first step in evaluating an argument is determining which type of argument it is, one cannot even begin. Here is an ethical argument that is an argument from analogy.1 Suppose that Bob uses his life savings to buy an expensive sports car. The bolero Perfidia speaks of love. Finally, it is distinct from the purporting view, too, since whether an argument can be affected by acquiring additional premises has no evident connection with what an argument purports to show. This is an essential tool in statistics, research, probability and day-to-day decision-making. [2], The process of analogical inference involves noting the shared properties of two or more things, and from this basis inferring that they also share some further property. These are all interesting suggestions, but their import may not yet be clear. The taco truck is not here. By contrast, he mentions that With inductive arguments, the conclusion contains information that goes beyond what is contained in the premises. Such a stance might well be thought to be no problem at all. From all of this data you make a conclusion or as the graphic above calls it, a "General Rule." Inductive reasoning allows humans to create generalizations about . Moreover, there appears to be little scholarly discussion concerning whether the alleged distinction even makes sense in the first place. By using induction, you move from specific data to a generalization that tries to capture what . 11. 2. Remarkably, not only do proposals vary greatly, but the fact that they do so at all, and that they generate different and indeed incompatible conceptions of the deductive-inductive argument distinction, also seems to go largely unremarked upon by those advancing such proposals. Becoming Logical: An Introduction to Logic. Birds are animals and they need oxygen to live. Eight equals itself (8 1 = 8). These types of inductive reasoning work in arguments and in making a hypothesis in mathematics or science. You and I are both human beings, so the color you experience when you see something green probably has the exact same quality. If person A believes that the premise in the argument Dom Prignon is a champagne; so, it is made in France definitely establishes its conclusion (perhaps on the grounds that champagne is a type of sparkling wine produced only in the Champagne wine region of France), then according to the psychological approach being considered, this would be a deductive argument. This is a false analogy because it fails to account for the relevant differences between a rabbit and animals that fly. Analogy: "a comparison between two things, typically for the purpose of explanation or clarification" Inductive reasoning: "the derivation of g. Vol. All Renaissance paintings are applied chiaroscuro. Some approaches focus on the psychological states (such as the intentions, beliefs, or doubts) of those advancing an argument. To argue by analogy is to argue that because two things . Examples should be sufficient, typical, and representative to warrant a strong argument. 19. 108-109. Therefore, the next race I will run will probably be a world record. However, for this proposal to categorically distinguish deductive from inductive arguments, it must be the case both that all deductive arguments embody logical rules, and that no inductive arguments do. Saylor Academy, Saylor.org, and Harnessing Technology to Make Education Free are trade names of the Constitution Foundation, a 501(c)(3) organization through which our educational activities are conducted. First, a word on strategy. But naturally occurring objects like eyes and brains are also very complex objects. Nala is an orange cat and she purrs loudly. For example, suppose that I have always owned Subaru cars in the past and that they have always been reliable and I argue that the new car Ive just purchased will also be reliable because it is a Subaru. Alternatively, the use of words like probably, it is reasonable to conclude, or it is likely could be interpreted to indicate that the arguer intends only to make the arguments conclusion probable. 13. In a false analogy, the objects may have some similarities, but they do not both have property X. This fact might not be evident from examining the account given in any specific text, but it emerges clearly when examining a range of different proposals and approaches, as has been done in this article. An argument from analogy is weakened if it is inadequate in any of the above respects. Higher-level induction Your examples of inductive argument patterns should not be expressed in premise form. Along the way, it is pointed out that none of the proposed distinctions populating the relevant literature are entirely without problems. New York: Random House, 1941. How does one distinguish the former type of argument from the latter, especially in cases in which it is not clear what the argument itself purports to show? The analogies above are not arguments. 5. At least in this case, adding a premise makes a difference. Claudia is a woman and has a knack for mathematics. 5th ed. 9. Therefore, on this proposal, this argument would be inductive. Moreover, her discussion, while perceptive, does not engage the issue with the level of sustained attention that it deserves, presumably because her primary concerns lay elsewhere.
