Abduction and hypothesis withdrawal in science essay

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.

Introduction Philosophical reflection on scientific discovery occurred in different phases. Prior to the s, philosophers were mostly concerned with discoveries in the broadest sense of the term, that is, with the analysis of successful scientific inquiry as a whole.

Philosophical discussions focused on the question of whether there were any discernible patterns in the production of new knowledge.

Because the concept of discovery did not have a specified meaning and was used in a very broad sense, almost all seventeenth- and eighteenth-century treatises on scientific method could potentially be considered as early contributions to reflections on scientific discovery.

Different elements of scientific inquiry were specified. Most importantly, the generation of new knowledge was clearly and explicitly distinguished from its validation, and thus the conditions for the narrower notion of discovery as the act or process of conceiving new ideas emerged.

It was further argued that conceiving a new idea is a non-rational process, a leap of insight that cannot be captured in specific instructions. Justification, by contrast, is a systematic process of applying evaluative criteria to knowledge claims. Advocates of the context distinction argued that philosophy of science is exclusively concerned with the context of justification.

The assumption underlying this argument is that philosophy is a normative project; it determines norms for scientific practice. Given these assumptions, only the justification of ideas, not their generation, can be the subject of philosophical normative analysis.

Discovery, by contrast, can only be a topic for empirical study. By definition, the study of discovery is outside the scope of philosophy of science proper. The introduction of the context distinction and the disciplinary distinction that was tied to it spawned meta-philosophical disputes.

For a long time, philosophical debates about discovery were shaped by the notion that philosophical and empirical analyses are mutually exclusive. They also maintained that it is a legitimate task for philosophy of science to develop a theory of heuristics or problem solving.

But this position was the minority view during much of 20th-century philosophy of science. Philosophers of discovery were thus compelled to demonstrate that scientific discovery was in fact a legitimate part of philosophy of science.

Philosophical reflections about the nature of scientific discovery had to be bolstered by meta-philosophical arguments about the nature and scope of philosophy of science. Today, however, there is wide agreement that philosophy and empirical research are not mutually exclusive.

Not only do empirical studies of actual scientific discoveries inform philosophical thought about the structure and cognitive mechanisms of discovery, but researches in psychology, cognitive science, artificial intelligence and related fields have become an integral part of philosophical analyses of the processes and conditions of the generation of new knowledge.

Several natural and experimental philosophers, notably Bacon, Descartes, and Newton, expounded accounts of scientific methods for arriving at new knowledge. They are relevant because philosophers of science have frequently presented 17th-century theories of scientific method as a contrast class to current philosophies of discovery.

The distinctive feature of the 17th- and 18th-century accounts of scientific method is that the methods are taken to have probative force Nickles This means that those accounts of scientific method function as guides for acquiring new knowledge and at the same time as validations of the knowledge thus obtained Laudan ; Schaffner 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?

Notwithstanding this fact, it is sometimes necessary to construct ways of rejecting the unfalsifiable hypothesis at hand by resorting to some external forms of negation, external because we want to avoid any arbitrary and subjective elimination, which would be rationally or epistemologically unjustified.
