## retroduction and abduction

e 1 ), http://www.commens.org/encyclopedia/article/chiasson-phyllis-abduction-aspect-retroduction, http://www.fordham.edu/halsall/mod/schiller-education.html, In one sense, Peirce tells us that an abductive inference is a response to an anomalous fact that results in a guess (or explanatory hunch) about the probable cause of that fact. H {\displaystyle b} When we combine the prefix “de” (to separate) with the suffix “ductive” (to lead), we have the meaning of deduction as “leading to separation, removal, or negation,” which are the goals and consequences of deductive reasoning. ∴ ∈ The economics of research is, so far as logic is concerned, the leading doctrine with reference to the art of discovery. Peirce’s Theory of Abduction. Thus in practical terms, the abduction/retroduction dilemma has two parts each of which stem from several dichotomous descriptions. O Retrieved from www.door.net/arisbe. Once readied, inductive reasoning is applied to test and evaluate the guess. e known to occur at least whenever a certain character (M) occurs. It has no purpose, unless recreation….” Can we have a norm for a form of logic which depends upon mathematics and ethics, but “has no rules, except this very law of liberty?” Or, is the abduction of musement of another sort than the abduction of critical logic? "[12] After obtaining possible hypotheses that may explain the facts, abductive validation is a method for identifying the most likely hypothesis that should be adopted. one inverted conditional for each value The truth is that the whole fabric of our knowledge is one matted felt of pure hypothesis confirmed and refined by induction. Your reasoning might be that your teenage son made the … This use of abduction is not straightforward, as adding propositional formulae to other propositional formulae can only make inconsistencies worse. {\displaystyle \omega _{Y{\tilde {\mid }}X}} Bloomington, IA.

Love words? {\displaystyle \therefore } ⊚ {\displaystyle \;{\widetilde {\phi }}} Because the looser “rules” of the methodeutic branch of logic allow for a variety of ways to demonstrate these specific and overarching reasoning methods, it is possible to use methodeutic logic to construct models for testing the patterns of action that make up each of the three types of inferences.5, Another good reason for separating these two concepts (abduction from retroduction) is that retroduction cannot be considered without also considering the relational patterns of (and among) all three types as inferences–as well as the relational aspects of the context for which it is being applied. a Inference to the Best Explanation, London: Routledge. Brent, J. H Aesthetics governs ethics, and ethics logic. Deductive reasoning allows deriving It cannot be defined operationally until we clarify some of the confusing contradictions about abductive reasoning with which Peirce left us. {\displaystyle X} When conducting qualitative research, scholars should consider the relation between data collection and analysis as well as between theory and data. CS1 maint: multiple names: authors list (. Normative science rests largely on phenomenology and on mathematics; metaphysics on phenomenology and on normative science” (Peirce, 1903/1955, “A Syllabus of Certain Topics of Logic”, p. 61). He considered his theory of abduction essential to (and even overarching of) his theory of pragmatism (Fann, 1970, p.47). For methodeutic, as the logic of scientific method, norms the logical methods which the construction and testing of hypotheses should occur. In 1911, he wrote, "I do not, at present, feel quite convinced that any logical form can be assigned that will cover all 'Retroductions'. Y Davis, D. (1972).

The “first” science of discovery, according to Peirce, is mathematics–which studies “what is and is not logically possible, without making itself responsible for its actual existence”(Peirce, 1903/1955b, “A Syllabus of Certain Topics of Logic”, p. 60). I am just now trying to get a small book written in which I positively prove just what the justification of each of the three types of reasoning consists in…and showing the real nature of Retroduction. In other cases, no new law is suggested, but only a peculiar state of facts that will "explain" the surprising phenomenon; and a law already known is recognized as applicable to the suggested hypothesis, so that the phenomenon, under that assumption, would not be surprising, but quite likely, or even would be a necessary result.

(Fann, 1970, p. 60). 374-375). [60], In addition to inference of function preconditions, abduction has been used to automate inference of invariants for program loops,[61] inference of specifications of unknown code,[62] and in synthesis of the programs themselves.[63]. In Sebeok, T. "The Play of Musement". Abduction, then, would not actually BE musement, or BE the reaction to a surprising fact and an ensuing hunch. Ketner, K. L. (1998). (Peirce, 1905/1955, What Pragmatism Is, p. 258). It could be that the answer to this question resides in some of Peirce’s later writings and existential graphs, which are not yet generally available. One can understand abductive reasoning as inference to the best explanation,[3] although not all usages of the terms abduction and inference to the best explanation are exactly equivalent. ′ Basically, it involves forming a conclusion from the information that is known. The advantage of using subjective logic abduction compared to probabilistic abduction is that both aleatoric and epistemic uncertainty about the input argument probabilities can be explicitly expressed and taken into account during the analysis. No, no! Induction is the reasoning method by which the idea is tested, evaluated, and eventually secured. X E Peirce and the Structure of Abductive Inference. (2001). . 1 Case: These beans are from this bag. Of course, even if we accept this aesthetic-abduction connection, the second aspect to the abduction/retroduction dilemma, which we discussed earlier, arises from Peirce’s statement that methodeutic (which is “nothing but heuretic”) “concerns abduction alone.” The category of methodeutic is supposed to provide the norms for scientific investigation–norms which must include the norms for other forms of inference (deduction and induction) as well as for abduction. [10] The methods are sound and complete and work for full first order logic, without requiring any preliminary reduction of formulae into normal forms. "[39] In 1903 Peirce called pragmatism "the logic of abduction" and said that the pragmatic maxim gives the necessary and sufficient logical rule to abduction in general. In 1910 Peirce made a three-way distinction between probability, verisimilitude, and plausibility, and defined plausibility with a normative "ought": "By plausibility, I mean the degree to which a theory ought to recommend itself to our belief independently of any kind of evidence other than our instinct urging us to regard it favorably. The power of agency is the power to motivate actions and inspire ultimately the shared understanding that characterizes any given society.[57]. {\displaystyle \mathbf {Y} } ) . ~ Even a well-prepared mind guesses oftener wrong than right, but our guesses succeed better than random luck at reaching the truth or at least advancing the inquiry, and that indicates to Peirce that they are based in instinctive attunement to nature, an affinity between the mind's processes and the processes of the real, which would account for why appealingly "natural" guesses are the ones that oftenest (or least seldom) succeed; to which Peirce added the argument that such guesses are to be preferred since, without "a natural bent like nature's", people would have no hope of understanding nature. The two conditions for {\displaystyle b_{X}(x),u_{X},a_{X}(x)\in [0,1]\,\!} with respective variables instead of probabilities, the analyst can express arguments as subjective opinions. Instead, abduction is done at the level of the ordering of preference of the possible worlds. ⊆ Then, once these processes are mastered, individuals can learn to effectively perform and apply each of these methods appropriately for the construction, explication, and evaluation of all sorts of conditional purposes (including hypotheses)–thus mastering the skills of Peirce’s concept of “right reasoning.”. In “Neglected Argument,” Peirce emphasizes that “musement” (the state from which an abductive inference is generated) must be an entirely unfettered process–following only the laws of “Pure Play.” “Now Play, as we all know,” wrote Peirce, “is a lively exercise of one’s powers. X {\displaystyle O} In other words, deduction derives the consequences of the assumed. Charles Peirce’s Guess at the Riddle: Grounds for Human Significance. In formal methods logic is used to specify and prove properties of computer programs. Remember, musement is a sort of speculation that arises during Pure Play–the activity that “has no rules, except this very law of liberty. X {\displaystyle x} Charles S.

[57], The question Gell asks in the book is, "how does it initially 'speak' to people?" 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. ∑ You conclude that they are friendsagain. Peirce, C. S. (1903), Harvard lectures on pragmatism, Peirce used the term "intuition" not in the sense of an instinctive or anyway half-conscious inference as people often do currently. 2.2 Revealing the multi-faceted causes of behavior is a complex aspect of research analysis that requires interpretative tools capable of unpacking the association between what people do, and the individual or structural factors encountered in their environment that shape behavioral responses. ), "The Encyclopedia of Philosophy," Macmillan Publishing Co, Inc. & The Free Press, New York. Abduction is performed by finding a set ∑ Primarily, methodeutic is nothing but heuretic and concerns abduction alone…”(Peirce, 1902, MS 175.329-330), [S]ince the whole business of heuretic, so far as its theory goes, falls under methodeutic, there is no kind of argumentation that methodeutic can pass over without notice. Sebeok, T. (1981) "You Know My Method". (Indeed, it turns out that some swans are black.). Fann, K.T. [ {\displaystyle E} Although normative, Peirce placed aesthetics in the position of firstness, overarching (informing) both ethics and logic. [Any] M is P Another significant benefit would be to enable an operational definition of abductive reasoning–one which can be delineated in critical logic with the same clarity as deduction. In another sense, abduction is a type of inference which is mathematically deduced from the categories and cannot be psychological. Cost: A simple but low-odds guess, if low in cost to test for falsity, may belong first in line for testing, to get it out of the way. 2. 447-496). ↩︎. ) You happen to know that Tim and Harry have recently had a terrible rowthat ended their friendship. Rule: All the beans from this bag are white. Rosenthal, S. B. . ~ He wrote: For Peirce, aesthetic denotes a qualitative state–within which one has the “freedom of the will” (as a one-sided affair) only to strive for the ideal (that which will make one’s life beautiful and admirable). (Eds.) ϕ Once a surprising fact is formed into a hunch, deduction and induction interact recursively with abduction to engender a hypothesis. Houser, N. & Kloesel, C. Yet, one cannot help wonder at Schiller’s influence upon the emergence of Peirce’s concept of abduction. subjective deduction denoted by the operator Information and translations of retroduction in the most comprehensive dictionary definitions resource on the web. It would only mean that, in addition to mathematical representations, other means “not admissible in critical logic” are available to this branch of logic for representing qualities and the relations of qualities of the normative sciences–including aesthetics, ethics, and logic. which takes its values from a domain ) being included in the explanations. Critique of arguments in their various modes (deduction, induction, abduction). The requisite restraint generally requires that the abductor intend to prevent the liberation of … Abduction guesses a new or outside idea so as to account in a plausible, instinctive, economical way for a surprising or very complicated phenomenon. This “terminological” violation is only temporary, since Peirce, by selecting the terms “abduction” and “retroduction,” provided us with a terminological justification for applying these terms to distinguish between two levels of concepts. SPV is a sub-series of the Value Inquiry Book Series of Editions Rodopi. X And how can one obey only the “very law of liberty,” yet be circumscribed by ethical norms (as Peirce claimed logic must be)? Once we remove abduction and retroduction from the realm of vagueness and can clearly delineate these processes and their applications for all to see, we can begin to develop effective ways of teaching others how to effectively apply these reasoning processes to all sorts of situations.

Since he was so precise in his use of definitive language, the rationale for separating the meanings in this way should begin with an examination of the root meanings of the words “retroduction,” “abduction” (and, while we are at it, for “deduction,” and “induction” as well). If any or all of the above is so, it would not mean that the logic of methodeutic (or of abduction as musing, guessing, or responding to surprise) cannot be represented mathematically. “Logical self-control is a perfect mirror of ethical self-control….”, “Pure Play [from which abductive inferences may result] has no rules, except the very law of liberty.”, first, that it is not psychological because “no such doctrine can be admitted into critical logic,” and, second, that methodeutic logic (which is the logic of scientific method) is nothing but heuretic; that it concerns abduction alone; and that this form of logic may resort “to certain methods not admissible in” speculative grammar or critical logic. Retroduction: ( , it holds that A subjective opinion thus applies to a state variable There, he provides a detailed description of how the abductive process (as musement) engages within and among the three categories (Peirce 1903/1955b, “A Syllabus of Certain Topics of Logic”, pp. Kaptchuk, T. J. Consequently, the conduct of abduction, which is chiefly a question of heuristic and is the first question of heuristic, is to be governed by economical considerations. ) It was Peirce's own maxim that "Facts cannot be explained by a hypothesis more extraordinary than these facts themselves; and of various hypotheses the least extraordinary must be adopted. Abductive reasoning allows inferring Consequently, the art of discovery is purely a question of economics. (Peirce, 1902, MS 175.329-330). Y Yet nearly a century after his death, Peirce’s concept of abduction is still poorly understood. Abduction will lead you to the best explanation. ABDUCTION: Age of the Aggrieved Party: For the offence of Kidnapping, section 361 of IPC lays down that the age of the aggrieved person should be below 16 in case of males and below 18 in case of females. Inductive reasoning allows inferring Given the many possible explanations for the movement of the eight ball, our abduction does not leave us certain that the cue ball in fact struck the eight ball, but our abduction, still useful, can serve to orient us in our surroundings. ⊚ ) .... Any hypothesis, therefore, may be admissible, in the absence of any special reasons to the contrary, provided it be capable of experimental verification, and only insofar as it is capable of such verification. inductive, deductive, abductive. E We might also suspect that the deliberate form of recursive analysis (the interplay of abduction, deduction, and induction), which we are referring to as “retroduction,” might provide the qualities and relations of qualities by which the individual processes within it (abduction, deduction, and induction) can be tested. M In any case, there are some signs that, toward the end of his life, he had begun thinking of the two concepts as intertwined, but distinct. The more familiar form of this word is the adjective, “heuristic.” A heuristic device is a tool (often an analytical tool in the form of a diagram, model, analogy, or metaphor) which helps to show how the qualities and relations of qualities are to be sought for a particular purpose. From this we might infer that “psychological factors” (such as “surprise,” “value,” and other modes dependent upon sense or affect) might be employable as heuristic devices for explaining abduction, while not actually belonging to abduction, to mathematics, or to any of the sciences of discovery. ; they are related by the domain knowledge, represented by a function The secret of the business lies in the caution which breaks a hypothesis up into its smallest logical components, and only risks one of them at a time. Deductive reasoning is used to reach a logical true conclusion. {\displaystyle a} In his memoir of methodeutic, Peirce wrote: So, we now are back to the two parts of our abduction/retroduction dilemma, for we have two claims for abduction: Thus in one sense, Peirce’s notion of abduction is the aesthetic activity of musement. “Retrofit” means choosing to go back and modify an earlier model of something with an improvement of some sort. 2 {\displaystyle x} {\displaystyle T} 0 (Ed.) [34] Like "Deduction, Induction, and Hypothesis" in 1878, it was widely read (see the historical books on statistics by Stephen Stigler), unlike his later amendments of his conception of abduction. can be used to abduce the marginal opinion Methodeutic, or speculative rhetoric, on the conditions for determination of interpretations. {\displaystyle \therefore } Note that the hypothesis ("A") could be of a rule. He regarded economics as a normative science whose analytic portion might be part of logical methodeutic (that is, theory of inquiry).[41]. , their effects are known to be Another type of reasoning, inductive, is also used. It allows any flight of imagination, provided this imagination ultimately alights upon a possible practical effect; and thus many hypotheses may seem at first glance to be excluded by the pragmatical maxim that are not really so excluded. u McKaughan, Daniel J. The “Second Stage” of inquiry is explication and demonstration of the hypothesis (by means of deduction) and the “Third Stage” is comprised of classification, testing, and evaluation. Amsterdam: Editions Rodopi. If surprisingly it stands up to tests, that is worth knowing early in the inquiry, which otherwise might have stayed long on a wrong though seemingly likelier track. ∴ ~ X In the same year, Peirce wrote that reaching a hypothesis may involve placing a surprising observation under either a newly hypothesized rule or a hypothesized combination of a known rule with a peculiar state of facts, so that the phenomenon would be not surprising but instead either necessarily implied or at least likely. The combination of the prefix “retro” (as deliberately “going backward”) with the suffix “ductive” from the Latin ducere (to lead) places the meaning of retroduction as “deliberately leading backward.” This implies that retroduction is intended to be a deliberate and recursive process involving more than the making of an abductive inference. His description of the process of musement in “Neglected Argument,” and the implication that this process is abductive (not retroductive) brings up again the questions of the first part of our abduction dilemma: Perhaps the first two questions above can be answered together. e Bowden, R.

[citation needed] Under this principle, an explanation is valid if it is the best possible explanation of a set of known data. Deductive reasoning is applied to explicate the guess and ready it for testing. Today abduction remains most commonly understood as induction from characters and extension of a known rule to cover unexplained circumstances. I perform an abduction when I so much as express in a sentence anything I see. Yet, at the same time, he described abduction/retroduction as comprising one entire branch of logic. In various writings in the 1900s[25][40] he said that the conduct of abduction (or retroduction) is governed by considerations of economy, belonging in particular to the economics of research. For example, given that "Wikis can be edited by anyone" ($${\displaystyle a_{1}}$$) and "Wikipedia is a wiki" ($${\displaystyle a_{2}}$$), it follows that "Wikipedia can be edited by anyone" ($${\displaystyle b}$$). Peirce used the terms: abduction and retroduction interchangeably for two concepts–one overarching the other. bringing a new idea (or hypothesis) up from the region where “all things swim” in the continuum by means of abduction (beginning with an aesthetic inference, which by following the “form” of abduction in Peirce’s critic, becomes a logical inference); using deduction to explicate and demonstrate aspects of that idea.

As to what one ought to desire, it is…what he will desire if he sufficiently considers it, and that will be able to make his life beautiful, admirable.

How can the logic of scientific method “concern abduction alone,” if abduction is only one of three forms of logical inference? Given the truth of the assumptions, a valid deduction guarantees the truth of the conclusion. This can also be called reasoning through successive approximation. being an explanation of into two components, one of which is a normal logic program, used to generate C. S.

Therefore, based upon their Latin derivations (to which Peirce was partial, as he was for Greek roots) our four terms have the following meanings: A big question (one which this writer cannot answer) is why would Peirce, who was otherwise meticulous in his use of terminology, apply the terms “retroduction” (which according to its Latin roots should mean deliberately “leading backward”) and “abduction” (which should mean “leading away from”) interchangeably? Additionally, we might also reasonably suspect that, when taken as a whole, Peirce’s methodeutic, which is (“nothing but heuretic and concerns abduction alone”) might provide the method by which the recursive analytical process of “retroduction” can itself be tested. X Peirce writes that: Peirce’s division of normative science is comprised of aesthetics, ethics, and logic (in that order), with ethics dependent upon aesthetics for its ideals, and logic dependent upon ethics for its principles of conduct. , Below, 'M' stands for a middle; 'P' for a predicate; 'S' for a subject. X 83) also illustrated retroduction as a five-step procedure, this supports Chiasson's (2001) conclusion of abduction as a narrower concept and a part of retroduction. = ~ "A Syllabus of Certain Topics of Logic'" (1903 manuscript), Peirce, C. S., "On the Logic of Drawing History from Ancient Documents", dated as. As Gell reasons in his analysis, the physical existence of the artwork prompts the viewer to perform an abduction that imbues the artwork with intentionality. e produces the set of inverted conditionals The pattern of actions of abductive reasoning must be known and well-tested before we can effectively identify the qualities and relations among qualities of the overarching pattern of retroductive reasoning. This process, unlike deductive reasoning, yields a plausible conclusion but does not positively verify it. Ithica, N. Y.: Cornell University Press. So, let us take up the latter assertion first. New York: Dover Publications. Note that categorical syllogisms have elements traditionally called middles, predicates, and subjects. A common assumption is that the effects of the hypotheses are independent, that is, for every In “A Neglected Argument for the Reality of God,”(Peirce, 1908/1958, pp. However, abduction has been largely neglected by nurse scholars. Abduction is then the process that picks out some member of {\displaystyle O} In 1908 Peirce described this plausibility in some detail. . a satisfying these two conditions, some other condition of minimality is usually imposed to avoid irrelevant facts (not contributing to the entailment of But among justifiable hypotheses we have to select that one which is suitable for being tested by experiment. {\displaystyle M} Ketner, K.

Peirce in the double sense of searching for explanatory instances and providing an explanation is a kind of complement for usual argumentation. Abduction as an Aspect of Retroduction. For a “surprising fact” to be noticed and for a subsequent “guess” as to its cause to be made according to normative principles (without any reference to psychology), there must be a normative category which (though seeming psychological) is dependent upon mathematics, as are all of the normative sciences. x {\displaystyle a_{Y}} O Peirce, C. S. (1902). Abductive validation is the process of validating a given hypothesis through abductive reasoning. X [Neglected Argument] is the First Stage of scientific inquiry, resulting in a hypothesis of the very highest plausibility….” His “Neglected Argument,” then, is comprised of the deliberate and recursive use of abduction, deduction, and induction, for engendering “…a hypothesis of the very highest plausibility [the hypothesis of the reality of God] whose ultimate test must lie in its value in the self-controlled growth of a man’s conduct of life” (Peirce, 1908/1958, pp. A side benefit of being able to define abductive reasoning in this way will be the ability to clear up the confusion between abduction and induction, allowing us to clearly delineate inductive reasoning as well. H For, such psychological attitudes as “musement,” “guessing,” or “surprise,” would be heuristic devices for representing the qualities of abduction. Abduction is the answer to this conundrum because the tentative nature of the abduction concept (Peirce likened it to guessing) means that not only can it operate outside of any pre-existing framework, but moreover, it can actually intimate the existence of a framework. {\displaystyle \omega _{X}=(b_{X},u_{X},a_{X})\,\!} Charles S. Peirce Selected Writings: Values in a Universe of Chance (P. Weiner, Ed.). X For, as you will see, the key to the “normative” nature of Peirce’s notion of abduction resides in the category of aesthetics. This is the introductory episode for a series on Child Abduction, trafficking and judicial kidnap. During this time, Chiasson gave many workshops and published three articles for scholarly journals: Educational Leadership, Journal of Learning Disabilities, Proceedings of the 1983 Systems Sciences Convention. Peirce, "On the Logic of Drawing Ancient History from Documents". Abductive planning with the event calculus. The most direct application of abduction is that of automatically detecting faults in systems: given a theory relating faults with their effects and a set of observed effects, abduction can be used to derive sets of faults that are likely to be the cause of the problem. b Abduction, deduction and induction 5 the scientific community. (special issue on abductive inference), Santaella, Lucia (1997) "The Development of Peirce's Three Types of Reasoning: Abduction, Deduction, and Induction", 6th Congress of the. In the philosophy of science, abduction has been the key inference method to support scientific realism, and much of the debate about scientific realism is focused on whether abduction is an acceptable method of inference. But what other conditions ought it to fulfill to be good? These methods have also been extended to modal logic. , Peirce on Abduction. Her book, Peirce’s Pragmatism: A Dialogue for Educators, has been accepted for publication as the first volume in the Studies in Pragmatism and Values Series. Nor is there any freedom to do right if one has neglected the proper discipline…. For Peirce tells us that an abductive inference cannot be in any way psychological, and is “deduced mathematically from the categories.” (Peirce, 1902, “Memoir 24”), In a fourth apparent contradiction, Peirce tells us that methodeutic, the third category of logic (and which is the logic of scientific method), is “nothing but heuretic and concerns abduction alone.” (Peirce, 1902, “Memoir 27”). Since mathematics is the “first science” of discovery, it depends upon no other of the sciences of discovery and informs them all. a Philadelphia: John Benjamins Publishing Company. X Nashville: Vanderbilt University Press. . a (1961). These parameters satisfy Thus the aesthetic provides the “norm” (as the “admirable” ideal) for other norms and, as such, is the only “norm” that can be obeyed at the same time as obeying the “very law of liberty” (or “freedom of the will”). b Between 1976 and 1980, she and Dr. Davis tested the reliability of her model by means of a non-verbal assessment. [38] In 1903 he offered the following form for abduction:[17]. {\displaystyle H'\subseteq H} entails {\displaystyle a} [citation needed]. Style: Viable Construct of Thought Patterning. A familiar example of abduction is a detective's identification of a criminal by piecing together evidence at a crime scene. {\displaystyle T} A particular individual may use the same reasoning method for all three of these activities, or a different method for each.) , where Peirce and Value Theory. Peirce’s Neglected Argument lends credibility to the proposition that one meaning of abduction (the one here referred to as “retroduction”) includes the processes of deduction and induction, as well as abduction, for its performance. Peirce held that all deduction can be put into the form of the categorical syllogism Barbara (AAA-1). Four of these apparently dichotomous descriptions follow: Adding to the confusion is Peirce’s identification of logic as one of three branches of normative science (aesthetics and ethics are the other two), meaning that the category of logic provides the norms (standards, rules, methods) by which each of the methods of reasoning are to be performed.

Ph.D. dissertation, University of Arizona, Tucson.
