Charles Sanders Peirce has been characterized as the greatest American philosophic genius. He is the creator of pragmatism and one of the founders of modern logic. James, Royce, Schroder, and Dewey have acknowledged their great indebtedness to him. A laboratory scientist, he made notable contributions to geodesy, astronomy, psychology, induction, probability, and scientific method. He introduced into modern philosophy the doctrine of scholastic realism, developed the concepts of chance, continuity, and objective law, and showed the philosophical significance of the theory (...) of signs and mathematical logic. The present series is the first published edition of his systematic works. (shrink)

In this important new work, Haack develops an original theory of empirical evidence or justification, and argues its appropriateness to the goals of inquiry. In so doing, Haack provides detailed critical case studies of Lewis's foundationalism; Davidson's and Bonjour's coherentism; Popper's 'epistemology without a knowing subject'; Quine's naturalism; Goldman's reliabilism; and Rorty's, Stich's, and the Churchlands' recent obituaries of epistemology.

Embodied agents use bodily actions and environmental interventions to make the world a better place to think in. Where does language fit into this emerging picture of the embodied, ecologically efficient agent? One useful way to approach this question is to consider language itself as a cognition-enhancing animal-built structure. To take this perspective is to view language as a kind of self-constructed cognitive niche: a persisting though never stationary material scaffolding whose critical role in promoting thought and reason remains surprisingly (...) ill-understood. It is the very materiality of this linguistic scaffolding, I suggest, that is responsible for some key benefits. By materializing thought in words, we create structures that are themselves proper objects of perception, manipulation, and thought. (shrink)

Andy Clark has argued that language is “in many ways the ultimate artifact” (Clark 1997, p.218). Fuelling this conclusion is a view according to which the human brain is essentially no more than a patterncompleting device, while language is an external resource which is adaptively fitted to the human brain in such a way that it enables that brain to exceed its unaided (pattern-completing) cognitive capacities, in much the same way as a pair of scissors enables us to “exploit our (...) basic manipulative capacities to fulfill new ends” (Clark 1997, pp.193-4). How should we respond to this bold reconceptualization of our linguistic abilities? First we need to understand it properly. So I begin by identifying and unpacking (and making a small “Heideggerian” amendment to) Clark’s main language-specific claims. That done I take a step back. Clark’s approach to language is generated from a theoretical perspective which sees cognition as distributed over brain, body, and world. So I continue my investigation of Clark’s incursion into linguistic territory by uncovering and illustrating those key ideas from the overall distributed cognition research programme which are particularly relevant in the present context. I then use this analysis as a spring-board from which to examine a crucial issue that arises for Clark’s account of language, namely linguistic inner rehearsal. I argue that while there is much to recommend in Clark’s treatment of this issue, some significant difficulties remain to be overcome. Via this critique of Clark’s position, alongside some proposals for how the revealed problems might be addressed, I hope to edge us that bit closer to a full understanding of our linguistic abilities.

In this paper I aim to show that the creation and manipulation of written vehicles is part of our cognitive processing and, therefore, that writing transforms our cognitive abilities. I do this from the perspective of cognitive integration: completing a complex cognitive, or mental, task is enabled by a co-ordinated interaction between neural processes, bodily processes and manipulating written sentences. In section one I introduce Harris’ criticisms of ways in which writing has been said to restructure thought (Goody 1968; McLuhan (...) 1962, 1964; Ong 1982). This will give us a preliminary idea about possible pitfalls for a cognitive integrationist account. The second section outlines, firstly, how integrated cognitive systems function. Secondly, the model is applied to a hybrid mental act where writing allows us to complete complex cognitive tasks. The final section outlines the sense in which, following Harris, there is “a more realistic picture of how writing restructures thought” [Harris, R., 1989. How does writing restructure thought? Language and Communication 9 (2/3) 99–106] that is concealed by the ‘romantic fantasies’ of theorists such as the above. This picture is one of writing providing an autoglottic space in which a new form of theoretical thinking becomes prevalent. The cognitive integrationist understands this in terms of the nature of the written vehicles and how we manipulate them. (shrink)

In Supersizing the Mind, Andy Clark argues that the human mind is not bound inside the head but extends into body and environment.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

This book consolidates and extends the authors’ work on the connection between iconicity and abductive inference. It emphasizes a pragmatic, experimental and fallibilist view of knowledge without sacrificing formal rigor. Within this context, the book focuses particularly on scientific knowledge and its prevalent use of mathematics. To find an answer to the question “What kind of experimental activity is the scientific employment of mathematics?” the book addresses the problems involved in formalizing abductive cognition. For this, it implements the concept and (...) method of iconicity, modeling this theoretical framework mathematically through category theory and topoi. Peirce's concept of iconic signs is treated in depth, and it is shown how Peirce's diagrammatic logical notation of Existential Graphs makes use of iconicity and how important features of this iconicity are representable within category theory. Alain Badiou’s set-theoretical model of truth procedures and his relational sheaf-based theory of phenomenology are then integrated within the Peircean logical context. Finally, the book opens the path towards a more naturalist interpretation of the abductive models developed in Peirce and Badiou through an analysis of several recent attempts to reformulate quantum mechanics with categorical methods. Overall, the book offers a comprehensive and rigorous overview of past approaches to iconic semiotics and abduction, and it encompasses new extensions of these methods towards an innovative naturalist interpretation of abductive reasoning.

For some time, it seemed that one had to choose between two sharply different theories of epistemic justification, foundationalism and coherentism. Foundationalists typically held that some beliefs were certain, and, hence, basic. Basic beliefs could impart justification to other, non-basic beliefs, but needed no such support themselves. Coherentists denied that there are any basic beliefs; on their view, all justified beliefs require support from other beliefs. The divide between foundationalism and coherentism has narrowed lately, and Susan Haack attempts to synthesize (...) these competing accounts into a view she calls "foundherentism.". (shrink)
