assess the quality of an inference to the best explanation

This element is a more accessible alternative to drag & drop reordering. For example, Elizabeth Fricker's "Inference to the Best Explanation and the Receipt of Testimony: Testimonial Reductionism Vindicated" provides a clear, accessible and yet very sophisticated defense of a form of IBE-based reductionism about testimonial justification. 73-93. van Fraassen, B. C. 1989. Inference to the Best Explanation is a kind of abductive reasoning identified by Gilbert Harman in 1965. Most of reality cannot be explained. Question 5 1 / 1 pts Using the rules for assessing inferences to the best explanation (in Chapter 6), which of the following is likely the best inference to the best explanation (making normal assumptions) for the following observation: “This milk tastes terrible.” It is probably really milkweed sap that someone put in a milk carton in the fridge Correct! [5] This topic is related to the previous one in so far as one way in which IBE could fail to be fundamental is if it could be reduced to some part of the Bayesian framework. [6] For example, gravitational waves are nowhere to be seen; we know them only through their effects. One morning you enter the kitchen to find a plate and cup on thetable, with breadcrumbs and a pat of butter on it, and surrounded by ajar of jam, a pack of sugar, and an empty carton of milk. A final paper on the epistemic status of IBE is Ali Hasan's "In Defense of Rationalism about Abductive Inference". Philosophy of Science 66: S424-35. Once you do this, you can check to see if the theory meets the min. Induction and Inference to the Best Explanation. Dellsén, F. 2018. The second edition has been substantially enlarged and reworked, with a new chapter on the relationship between explanation and Bayesianism, and an extension and defence of the account of contrastive explanation. It depends upon our coming up with the right explanation as one of the candidates It generally leads us away from scientific explanations Question 11 1 / 1 pts The following is one of the ways (listed in our text) to assess the quality of an inference to the best explanation: Is it indubitably true? Bayesianism and Inference to the Best Explanation. In some of the other papers, IBE is frequently referred to, but it was not clear (to this reviewer at any rate) that the discussion applied specifically to IBE as opposed to any other form of non-deductive reasoning. [8] Although Carter and Pritchard do not say so explicitly, I assume they mean that the ground for doubting IBE would necessarily be a ground for doubting enumerative induction. Many philosophers believe that this describes a paradigm of cogent non-deductive inference rules; indeed, it's becoming increasingly common for philosophers to claim that all cogent non-deductive inferences are, or ultimately reduce to, inferences to the best explanation. Dellsén, F. 2017b. In other areas of our field, the phrase "Inference to the Best Explanation" appears too often to be invoked to use a rather ambiguous set of considerations to support a favored philosophical theory, with only the weakest signs of awareness of the very considerable difficulties involved in justifying, applying or even formulating IBE. Having discussed four papers that concern the relationship between IBE and Bayesianism,[4] I turn now to the related issue of whether IBE is a fundamental or reducible type of non-deductive inference. pts Using the rules for assessing inferences to the best explanation in Chapter, 283 out of 303 people found this document helpful, Using the rules for assessing inferences to the best explanation (in Chapter, 6), which of the following is likely the best inference to the best explanation. Interpretive explanation concerns the meaning of … The following is one of the ways (listed in our text) to assess the quality of an, Which one of the following is most likely, The answer can be found in Section 6.5, “Inference to the Best Explanation,”, With Good Reason: A Guide to Critical Thinking. However, KMR's reduction takes a very different form than Fumerton's. J. Adam Carter and Duncan Pritchard's "Inference to the Best Explanation and Epistemic Circularity" discusses what a justification for IBE would have to be like in order for it not to be objectionably circular. Hasan meets this Ramseyan challenge head on and argues extensively that we do have an awareness of the values of these probabilities in many cases. [1] This measure turns out to entail that one hypothesis H1 has greater explanatory power than another H2, relative to some evidence E, if and only if the likelihood of E is greater on H1 than on H2 (i.e., Pr(E|H1) ˃ Pr(E|H2)). roughly the question of whether IBE is justified, rational, or reliable. However, this last move seems to me to be a mistake, since a 'probability relation' of this kind would simply not satisfy the formal features for something to be a probability function over the relevant propositions. Step 3. Inference to the Best Explanation (IBE) is usually employed in the Scientific Realism debates. Oxford: Oxford University Press, pp. Abductively Robust Inference. Concept formulated by Princeton philosopher Gilbert Harman in his paper ‘The Inference to the Best Explanation’, Philosophical Review 74 (1965). Inference to the Best Explanation Richard Johns revised October 2008 Before we can discuss inference to the best explanation, we must be clear on what an explanation is. 2011. The obvious problem with this proposal -- recognized by KMR -- is of course that it is not immediately clear that it amounts to reduction, as opposed to an explication, of IBE. 1. London: Kegan, Paul, Trench, Trubner & Co., pp. Philosophical Quarterly 69: 428-44. Test the theories with the criteria of adequacy. Ramsey, F. P. 1931. The following is one of the ways listed in our text to assess the quality of an inference to the best explanation: Which one of the following is most likely not an inference to the best explanation? Is the following argument deductive or inductive? The data continue to … There are however more uses of IBE, namely as an epistemological theory of testimony and as a means of categorising and justifying the sources of evidence. 1. . To this end, they distinguish two different kinds of rule-circularity: an argument is narrowly rule-circular when it employs the very same inference rule that the argument is meant to justify; by contrast, an argument is widely rule-circular when it employs an inference rule from the same 'epistemic framework' as the one it is meant to justify. The whole purpose of the inference-to-the-best-explanation recipe is to assess the quality of evidence in an argument. ", outlines a case for nevertheless adopting van Fraassen's conception of a Bayesian IBE and using it to replace rather than supplement Bayesian conditionalization. Harman (1965) and Weintraub (2013). You happen to know that Tim and Harry have recently had a terrible rowthat ended their friendship. Bird suggests that internal virtues determine the prior of the hypothesis, i.e. Arguably the idea goes back to Peirce, although Peirce's views are not altogether easy to excavate. This lack of focus on the finer details of IBE specifically may sometimes be frustrating to those readers who are looking for papers devoted to this particular inference rule. Before you can evaluate an explanatory theory, you must express it in a statement that's as clear and specific as possible. This is especially unfortunate since Weintraub, in her contribution to this very volume (more on which below), explicitly refers to and convincingly criticizes Fumerton's position on this issue (pp. 156-198. Cambridge: Cambridge University Press, pp. The Inference to the best explanation. Step 2: Assess the Evidence for the theory. Best Explanations contains several other interesting papers that I can mention only very briefly -- some of which deserve to be widely read and discussed. Studies in History and Philosophy of Science 61: 32-40. After all, any two rules such that there are grounds for doubting each one will have a common ground – e.g., the conjunction of the two previous grounds – that will serve as a ground for doubting both. Utilize the tools of reason assessment for this type of argument in order to present your case for thinking that the argument is inductively weak / fallacious, or that the argument is inductively strong. The course closes by showing how you can use probability to help make decisions of all sorts. [2] The latter comes to much the same thing as Schupbach’s explanatory power, since the expectedness of the evidence, P(E), cancels out in a comparison of two hypotheses’ external virtues relative to the same evidence. Weintraub considers five different arguments for thinking that IBE is not a cogent inference rule, and suggests that only two of these have analogues for enumerative induction. [3] A similar criticism applies to Williamson’s ‘evidential probability’ (Kaplan 2009). Although the idea that IBE can partly be identified with relative likelihoods in this way is familiar and widely endorsed (e.g., Okasha 2000; Dellsén 2018), Schupbach's route to this conclusion is certainly novel and worth further study. Firstly I explore several alternatives to include explanatory considerations in Bayes's Theorem. According to KMR, this inference cannot be described as an instance of IBE, since being in an oxygenated atmosphere intuitively does not 'best explain' the fire. Philosophical Review 74: 88-95. A form of inductive reasoning in which we reasons from premises about a state of affairs to an explanation of that state of affairs: ... Assess the Evidence for the theory. Henderson outlines her 'emergent compatibilism' (see Henderson 2014) according to which the conclusions that would be licensed by IBE are automatically obtained in a Bayesian framework, given certain natural assumptions about distributions of prior probabilities.
