Most have con- 8 cluded that no logic of discovery exists and, moreover, that a rational model 9 of discovery is impossible. In short, scientific discovery is irrational and there 10 is no reasoning to hypotheses.
Today abduction remains most commonly understood as induction from characters and extension of a known rule to cover unexplained circumstances.
Sherlock Holmes uses this method of reasoning in the stories of Arthur Conan Doylealthough Holmes refers to it as deductive reasoning. The hypothesis is framed, but not asserted, in a premise, then asserted as rationally suspectable in the conclusion.
Thus, as in the earlier categorical syllogistic form, the conclusion is formulated from some premise s. But all the same the hypothesis consists more clearly than ever in a new or outside idea beyond what is known or observed.
Induction in a sense goes beyond observations already reported in the premises, but it merely amplifies ideas already known to represent occurrences, or tests an idea supplied by hypothesis; either way it requires previous abductions in order to get such ideas in the first place. Induction seeks facts to test a hypothesis; abduction seeks a hypothesis to account for facts.
Note that the Abduction and hypothesis withdrawal in science essay "A" could be of a rule. It need not even be a rule strictly necessitating the surprising observation "C"which needs to follow only as a "matter of course"; or the "course" itself could amount to some known rule, merely alluded to, and also not necessarily a rule of strict necessity.
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.
Inhe wrote, "I do not, at present, feel quite convinced that any logical form can be assigned that will cover all 'Retroductions'. For what I mean by a Retroduction is simply a conjecture which arises in the mind.
Consider what effects, that might conceivably have practical bearings, we conceive the object of our conception to have.
Then, our conception of these effects is the whole of our conception of the object.
It is a method for fruitful clarification of conceptions by equating the meaning of a conception with the conceivable practical implications of its object's conceived effects.
Peirce held that that is precisely tailored to abduction's purpose in inquiry, the forming of an idea that could conceivably shape informed conduct. In various writings in the s   he said that the conduct of abduction or retroduction is governed by considerations of economy, belonging in particular to the economics of research.
He regarded economics as a normative science whose analytic portion might be part of logical methodeutic that is, theory of inquiry. Stechiology, or speculative grammar, on the conditions for meaningfulness. Classification of signs semblances, symptoms, symbols, etc.
Logical critic, or logic proper, on validity or justifiability of inference, the conditions for true representation. Critique of arguments in their various modes deduction, induction, abduction. Methodeutic, or speculative rhetoric, on the conditions for determination of interpretations.
Methodology of inquiry in its interplay of modes. Peirce had, from the start, seen the modes of inference as being coordinated together in scientific inquiry and, by the s, held that hypothetical inference in particular is inadequately treated at the level of critique of arguments.
That is Peirce's outline of the scientific method of inquiry, as covered in his inquiry methodology, which includes pragmatism or, as he later called it, pragmaticismthe clarification of ideas in terms of their conceivable implications regarding informed practice.
Classification of signs[ edit ] As early as Peirce held that: Hypothesis abductive inference is inference through an icon also called a likeness. Induction is inference through an index a sign by factual connection ; a sample is an index of the totality from which it is drawn.

Deduction is inference through a symbol a sign by interpretive habit irrespective of resemblance or connection to its object. InPeirce wrote that, in abduction: In Peirce described this plausibility in some detail.
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.
In Peirce made a three-way distinction between probability, verisimilitude, and plausibility, and defined plausibility with a normative "ought": The phrase "inference to the best explanation" not used by Peirce but often applied to hypothetical inference is not always understood as referring to the most simple and natural hypotheses such as those with the fewest assumptions.Philosophy of Science.
Abduction and Hypothesis Withdrawal in Science.
Lorenzo Magnani University of Pavia, Pavia, Italy [email protected] ABSTRACT: This paper introduces an epistemological model of scientific reasoning which can be described in terms of abduction, deduction and induction. The aim is to emphasize the significance of abduction in order to illustrate the problem-solving process and to .
A good hypothesis starts with a clear research question. What is the role of abduction in arriving at clear research questions? Are there any inherent dangers in using this approach, strategic guessing, to explore research questions for inquiry?

A new abstraction paradigm aimed at unifying the different perspectives and providing some design insights for future ones is proposed here: the aim is to emphasize the significance of abduction in order to illustrate the problem solving process and to propose a unified epistemological model of .
These three kinds of reasoning are Abduction, Induction, and Deduction. [—] All the ideas of science come to it by the way of Abduction. Abduction consists in studying facts and devising a theory to explain them.
Its only justification is that if we are ever to understand things at all, it must be in that way.
