Our brains make up a series of signs and are engaged in making or manifesting or reacting to a series of signs: through this semiotic activity they are at the same time engaged in “being minds.” An important effect of this semiotic activity of brains is a continuous process of “externalization of the mind” that exhibits a new cognitive perspective on the mechanisms underlying the semiotic emergence of abductive processes of meaning formation. I consider this process of externalization interplay critical (...) in analyzing the relation between meaningful semiotic internal resources and devices and their dynamical interactions with the externalized semiotic materiality suitably stocked in the environment. The last part of the paper will describe some aspects of this interplay between external diagrammatization and internal recapitulation showing the specificity of their co-evolution. (shrink)

In philosophy of science, the literature on abduction and the literature on styles of thinking have existed almost totally in parallel. Here, for the first time, we bring them together and explore their mutual relevance. What is the consequence of the existence of several styles of scientific thinking for abduction? Can abduction, as a general creative mode of inference, have distinct characteristic forms within each style? To investigate this, firstly, we present the concept of abduction; secondly we analyze what is (...) understood by styles of thinking; thirdly, we give some comments on abduction and styles of thinking by analyzing examples of scientific discovery or innovation within each style. We develop a case-based comparative investigation of creative aspects of abductive reasoning with examples drawn from different styles of scientific thinking and doing as understood by the Crombie/hacking tradition. We argue that abduction, as a general mode of reasoning, can have a variety of specific expressions enabled and constrained by the styles of scientific thinking. Finally, we draw some conclusions on the relationship between abduction and styles of thinking suggesting that scientific discovery is a dynamical goal-directed activity within the scientific community that benefits from distinct styles of thinking and doing research.

The paper seeks to explain in what sense pragmatism was for Peirce a doctrine of logic. It is argued that pragmatism is a doctrine of logic for Peirce because its maxim, the pragmatic maxim, is a maxim of the methodeutic of abduction, i.e., concerns the method of selecting hypotheses for experimental testing. The paper also connects this idea to Peirce’s 1913 thesis according to which pragmatism contributes to the security but not to the uberty of reasoning. The connection consists in (...) that by excluding hypotheses that cannot be tested, the maxim renders the whole process of reasoning more secure, while any explanatory hypotheses is “uberous” in Peirce’s sense as any other.

In this article, I compare two varieties of abduction as reconstructive models for analysing discovery. The first is 'Hansonian abduction', which is based on N. R. Hanson's formulations of abduction. The other is 'Harmanian abduction', the Inference to the Best Explanation (IBE) model, formulated especially by Gilbert Harman. Peter Lipton has analysed processes of discovery on the basis of his developed form of Harmanian abduction. I argue that Hansonian abduction would, however, be a more apt model for this purpose. As (...) an example, I reconstruct, in a Hansonian manner, Ignaz Semmelweis's research on childbed fever and compare it to the IBE reconstruction of Lipton. I argue that Hansonian abduction is in accordance with Lipton's aim of taking into account the distinction between actual and potential explanations on the one hand, and between likely and lovely explanations on the other. I maintain that a developed version of Hansonian abduction combined with loveliness gives an important, new conceptual means for analysing processes of discovery. (shrink)

This account will demonstrate that the element of surprise is a fundamental device in establishing double consciousness regimes; it further shows how such dialogic paradigms foster abductive inferences by filtering out irrelevant percepts/antecedents. The account sets up Peirce’s Pheme to be the primary device which shocks interpreters’ sensibilities – starting them on a course to question conflicting principles between ego and non-ego. The natural disposition of surprise to instantaneously deliver insight into which antecedents are relevant to vital, anomalous consequences demonstrates (...) its indispensability in generating logical and semiotic advances. For Peirce, vividness, as an element of surprise in Secondness, is largely responsible for the nuts and bolts of how surprise facilitates logic; its means to activate searches for plausible antecedents makes vividness the prime candidate. The success of vividness at turning the mind of interpreters to new ways of explaining the consequence largely hinges upon the external properties of the unexpected consequence – not merely objects’ instantaneity, but their striking characteristics, as well. Even though vividness is external, it produces internal responses, in the form of a war against feelings. In this way, double consciousness paradigms are initiated, which, in turn, call for hypothesis generation. (shrink)

In this paper we maintain that abductive inferential processes should be embedded to a more general outlook on human cognition. Abduction has clear a.nities to the so-called interrogative model of inquiry in which inquiry and reasoning are conceptualized as a dialogue. We think, in addition, that dialogicality must be broadened to a “trialogical” framework which means a threefold relationship with mediating artefacts where the inquirer, other inquirers , and the object of knowledge are inextricably bound up with each other in (...) long term processes of inquiry. Seen from this perspective Peirce's semeiotic pragmatism has close connections to modern ideas about distributed cognition; also to Pera's dialectical model of science, and Davidson's theory of triangulation concerning human mind, cognition, and knowledge.
