This paper proposes a biosemiotic conception of theories, as non-intentional organic theories, which is based on an analysis and comparison of philosopher Norwood Russell Hanson’s account of theories and zoologist Jakob von Uexküll’s theory of organisms. It is argued that Hanson’s proposals about scientific theories and their relation to observation are semiotic in nature and that there exists a correspondence between Hanson’s depiction of the relationship between theories, observation, and reality and von Uexküll’s views on the relationship between organisms and (...) their environments. This correspondence supports an account of theories that depicts them as organic extensions of our perceptual physiology. Among the epistemological consequences of this account are the following: The kind of correspondence that is established through theories between a subject and reality is related rather to a subject’s actions than to a faithful representation of every aspect of the world, it suggests a strong emphasis on the creative aspects of knowledge acquisition, and it urges a reassessment of the evolutionary epistemology of theories.

Kelly suggested that it was useful to consider anyone as functioning as a scientist, in the business of applying theories, making hypotheses and predictions and testing them out in the practice of everyday life. One of Charles Peirce’s major contributions was to develop the disciplines of logic and the philosophy of science. We can deepen and enrich our understanding of Kelly’s vision by looking at what Peirce has to say about the process of science. For Peirce, the essence of science (...) was the application of the laws of inference. He developed a much broader concept of logic, elaborating the processes of deduction and induction and adding to these the logic of hypothetical inference, or ‘abduction’, even as Kelly broadened it further in his “departure from classical logic”. Examining the implications of these three forms of inference allows us to elaborate the dynamics involved in the process of construing, ordinacy and the cycles of experience, creativity and decision making. This is the second of a three part series examining the relationship between the work of Peirce and Kelly. The third will include a look at phenomenology, bipolarity, the self, dialogical process and sociological considerations. (shrink)

This paper considers the views of two figures whose work falls on either side of the heyday of American pragmatism, Thomas Reid (1710-96) and Ludwig Wittgenstein (1889-1951). The broad similarities between Reid’s and (the later) Wittgenstein’s views, and in particular their epistemological views, has been well documented. Here, I argue that such similarities extend to the relation in their work between common sense and the presence of elements in their thought that can be considered pragmatist in some important respect. Beginning (...) with Reid, I argue that some specific theses commonly associated with pragmatism – e.g., that meaning, truth, or the justifiedness of a belief in a matter of practical effects or efficacy – clearly run counter to his stated views, and stand in tension with the well-known common sense character of his work. At the same time, however, and as others have noted, other pragmatist themes and ideas – e.g., about the close relations between belief (and doubt) and action, theory and practice, and facts and values – do have a clear precedent in Reid (§2). Most fundamentally, however, Reid’s epistemological views in particular display an adherence to the idea that practice is somehow primary – an idea that’s central to pragmatism ‘broadly conceived’, as Brandom calls it and, according to some others (e.g., Putnam, Cavell), to pragmatism per se. What’s more, once we are clear on the respect(s) in which Reid’s views do incorporate an important pragmatist element, it becomes clear that far from being at odds with, or needing supplementation by, the latter, common sense is in fact inseparable from it (§3). Finally, I turn (§4) to Wittgenstein, and suggest that the same close connection between pragmatist elements and common sense as we find in Reid is present here as well: like Reid, Wittgenstein rejects several ‘narrow’ pragmatist theses; but he too ascribes practice a crucial role. And while he seldom explicitly refers to common sense, the notions of good judgment, and of the reasonable person – hallmarks of common sense, as Reid conceives of it – are at the heart of Wittgenstein’s later epistemological views as well.

El artículo analiza las principales intuiciones de inspiración pragmatista empleadas por el segundo Wittgenstein contra el escepticismo filosófico. Comparte con Peirce una orientación epistemológica antiescéptica que comprende: i) el rechazo de la duda filosófica, ii) el compromiso con certezas y el falibilismo, y iii) la defensa de una visión no intelectualista de la creencia. Con James comparte un enfoque metodológico en el que destaca la forma de deconstruir y replantear los problemas filosóficos. Conocer aquella orientación epistemológica y este enfoque metodológico (...) torna más nítida la aproximación terapéutica con la que combate Wittgenstein el escepticismo filosófico. (shrink)
