Realism in Action is a selection of essays written by leading representatives in the fields of action theory and philosophy of mind, philosophy of the social sciences and especially the nature of social action, and of epistemology and philosophy of science. Practical reason, reasons and causes in action theory, intending and trying, and folk-psychological explanation are some of the topics discussed by these leading participants. A particular emphasis is laid on trust, commitments and social institutions, on the possibility of grounding social notions in individual social attitudes, on the nature of social groups, institutions and collective intentionality, and on common belief and common knowledge. Applications to the social sciences include, e.g., a look at the Erklären-Verstehen controversy in economics, and at constructivist and realist views on archeological reconstructions of the past

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

Ilkka Niiniluoto, a distinguished philosopher of science, has been a tirelesspokesman for scientific realism and reason more generally. Trained in the tradition of the Finnish school of inductive logic he has refined the notion of truthlikeness (verisimilitude) to make the realist idea scientific progress mathematically exact. Niiniluotos main technical works are included in his books Is Science Progressive? (1984) and Truthlikeness (1987), but his most recent general defense of scientific realism culminated in his Critical Scientific Realism (1999). Niiniluoto is, since 1981, Professor of Theoretical Philosophy at the University of Helsinki, and since 2003 the Rector of the University. He has for a long time been one of the most prominent public intellectuals in Finland. This Festschrift brings about a selection of philosophical essays on Niiniluotos philosophy by prominent member of the international community. The contributions are grouped around three themes. The first ones deal with philosophy of logic, the philosophy of language, and the philosophy of mathematics, and the second group consists of papers on induction, truthlikeness, and scientific progress. The third part collects essays on the history of logical empiricism, the ontology of social groups, and the dispute between theism and atheism. This book is a tribute to Ilkka Niiniluoto on his 60th birthday, and it also contains Niiniluoto's replies to comments, queries and criticisms.

The article addresses the methodological debate within archaeology over its self-understanding and cognitive profile. Is archaeology an interpretative humanities discipline or rather a natural science? More specifically, should it view the human past as an expression of (series of) essentially symbolic human strivings or should it rather turn to the exact sciences for a model? The paper portrays inquiry in general and in archaeology specifically in terms of questions and answers. The fundamental idea is that the big research questions proposed by archaeologists fall squarely within the humanities. However, when searching for answers it uses an increasingly wide variety of methods, models and tools from the natural sciences. The paper also addresses fundamental epistemological, methodological and ontological issues over the credentials and nature of our knowledge of the past. How do archaeologists who are often inclined to adopt a realist stance towards the human past deal with the variety of constructivist challenges? How do values and non-epistemic considerations enter the scene? To count as a respectable science is archaeology forced to maintain that facts should be allowed to speak for themselves? And what can and should count as a fact? What would it mean to make things talk? The article ends with a brief note on the nature of archaeology as a discipline or interdiscipline, and on how it aspires to go beyond brute physical and behavioral facts.

In the middle of a conference on the logic of science, an eminent biologist once said: “Does it not bother you guys that we scientists do not use any logic at all.” This statement was meant to be a friendly provocation, but there also was a serious message. Scientists often say that the logical analyses are exercises in formal logic and fail to illuminate what the scientists are doing, actual scientific practice. This recurring complaint, although not completely as I will suggest, has not gone unnoticed in the philosophy of science. Indeed, the current trend in analytic philosophy of science as well as in teaching the method of science has been away from logic as a means of illuminating scientific inquiry.

Doren Recker has criticized the prevailing accounts of Darwin's argument for the theory of natural selection in the Origin of Species. In this note I argue that Recker fails to distinguish between a deductive short argument for the principle of natural selection, and a non-deductive, long argument which aims at establishing that the principle has explanatory power in the various domains of application. I shall try to show that the semantic view of theories, especially in its structuralist form, makes it easy to distinguish between the two arguments and to explain how Darwin's long argument counts as one argument. I also raise a question about Recker's views on Darwin's mid-Victorian background, arguing that Newton's First Rule of Reasoning was not just a constraint on hypotheses involving unobservables, but a general request to keep conjecture and certainty apart

Detectives and scientists are in the business of reasoning from observations to explanations. This they often do by raising cunning questionsduring their inquiries. But to substantiate this claim we need to know how questions arise and how they are nurtured into more specific hypotheses. I shall discuss what the problem is, and then introduce the so-called interrogative model of inquiry which makes use of an explicit logic of questions. On this view, a discovery processes can be represented as a model-based game in which an inquirer subjects a source of information to a series of strategically organized questions. Strategic principles and why-questions are especially important in heuristical reasoning. Why-questions have their own peculiar nature among questions. They indicate that the inquirer's expectations are somehow disappointed, and that is cognitively challenging. In a finished argument why-questions can be omitted, but in the search for more specific questions they are highly important. As a detetective example I shall analyze Sherlock Holmes reasoning in Silver Blace, the scientific one is A.R. Wallace's discovery of the principle of natural selection. In both of these examples the meaning of questions, especially of well-chosen why-questions, of strategic principles, and of highly structured background knowledge come to the fore. Good questions frequent those who have orderly expectations, based on experience and expertise (detectives!) or highly structured background theories (scientists!).
