Popper: Epistemology, Misc

Entender algo sobre un mundo que se nos presenta de modo desordenado e incompleto constituye buena parte de la tarea de la filosofía y de la ciencia. La racionalidad, los modelos, y el mundo social introducen preocupaciones propias de la filosofía de la ciencia en general y de la epistemología de la economía en particular. Los aportes de Popper, Lawson, Mäki, Hayek y Cartwright se expresan en estos trazos como intentos abiertos para alcanzar a comprender nuestro mundo.

Karl Popper presenta al realismo como su posición acerca del conocimiento, distinguiéndola del instrumentalismo y del esencialismo. Ataca del primero la consideración meramente instrumental de las teorías científicas. Del segundo, critica que sostenga la posibilidad de establecer la verdad definitiva de las teorías, y que éstas describen esencias. El instrumentalismo coincide con Popper en que no hay conocimiento de esencias a través de las teorías científicas, pero de ello infiere que las teorías son meros instrumentos. Popper señala que el carácter (...) meramente instrumental de las teorías las vuelve irrefutables. Porque un instrumento de predicción no puede ser refutado (cf. Popper (1972a, p. 149)). Además, el instrumentalismo no puede explicar el interés del científico por la verdad. Su esencialismo modificado, toma del esencialismo que “el científico aspira a una verdadera descripción del mundo o de algunos de sus aspectos, y a una explicación verdadera de los hechos observables” (Popper, 1972a, p. 150). Pero agrega que no es posible saber con certeza si sus hallazgos son verdaderos. Resaltar el carácter conjetural de las teorías científicas no implica disminuir la aspiración del científico a describir algo real. (shrink)

In this chapter, I argue that Karl Popper was a communitarian philosopher. This will surprise some readers. Liberals often tout Popper as one of their champions. Indeed, there is no doubt that Popper shared much in common with liberals. However, I will argue that Popper rejected a central, though perhaps not essential, pillar of liberal theory, namely, individualism. This claim may seem to contradict Popper's professed methodological individualism. Yet I argue that Popper was a methodological individualist in name only. In (...) fact, methodological individualism faded from Popper's vocabulary as he moved institutions and situational analysis more firmly to centre-stage. Popper's focus on institutions and situations constitutes what I call his communitarianism. If my interpretation is correct, then theorists in the socio logy of scientific knowledge and communitarian epistemology should reconsider their long-standing distrust of Popper's philosophy. Indeed, they may have much to gain by treating Popper as a friend rather than a foe. (shrink)

The relevance of the Popperian heritage to the internalism-externalism issue is explored. First, the nature of the controversy between Popper and his disciples, Watkins and Zahar, about basic statements is discussed. Popper's resistance to Watkins' and Zahar's elaborations is suggested to be motivated by his implicit antiinternalist attitude that is misnamed by him as antipsychologism. Next, instead of a conventionalist, an externalist reading of Popper's mention about the role of a „scientific jury” in accepting basic statements is offered. It is (...) doubtful, however, whether Popper can be considered an externalist, for he rejects the concept of justified belief altogether. Still, it is suggested that future elaboration of his ideas may help to explain away the circularity apparent in Goldman's reliabilism and arrive at a more tenable form of externalism. (shrink)

The Myth of the Framework, Popper attacks the doctrine that truth is relative to one's intellectual background. The same collection refers to his "situational analysis." This article explores the implications of both for spatial planning. Spatial planners have to justify proposals. The article first summarizes earlier work on planning methodology evolving around the rationality principle and the implications for it of Popper's work for how to do this. It then discusses the notion of the definition of the decision situation, which (...) flows from this principle. This, of course, implies taking a leaf out of Popper's book where he discusses situational analysis. The article then gives an account of the author's work on Dutch planning doctrine, relating it to the definition of decision situations in planning and confronting it with Popper's strictures against The Myth of the Framework. The conclusion is that, whereas in the sciences that are after explain ing reality in terms of universal laws, Popper's argument holds, in planning it does not. Planning is about the search for the right course of action. In it, Popper's concern with fighting relativism and what he calls "justification" is misplaced. The quality of decisions depends on the position and the concerns of the decision taker. Relativism is in-built and so is the need to justify decisions. (shrink)

Scholars Karl R. Popper and Thomas S. Kuhn developed new frameworks that helped shape practical science policies and contributed to a greater understanding of the power and limitations of science. Popper did not accept induction as a method of arriving at scientific conclusions and rejected the justification of scientific theories and hypotheses. On the other hand, Kuhn advocated the progress of science and accepted some principles of scientific practices, including law, theory, instrumentation and application. -/- .

Karl Popper attempted to give an account of scientific research as the rational pursuit of the truth about nature without any appeal to what he took to be the fictitious notion of non-demonstrative or inductive support. Deductive inference can be seen to be inference enough for science, he claimed, once we appreciate the power of data to refute theory. Many of the standard objections to Popper's account purport to show that his deductivism actually entails a radical scepticism about the possibility (...) of scientific knowledge. Some of these objections appear unanswerable in the context of the traditional analysis of knowledge as justified true belief; but this is neither a conception of knowledge that Popper himself accepted nor one that is currently in fashion. Reliabilism, the view that knowledge is a true belief generated by a reliable method, is now a popular replacement for the traditional analysis and one that is closer to Popper's own conception of knowledge. My aim in this essay is to consider in brief compass the prospects of a reliabilist reading of Popper's account of science. Such a reading makes it possible to turn some of the standard objections and helps to show which of Popper's views should be accepted and which rejected. (shrink)

The question of objectivity asks how we can bridge the gap between ourselves and the world outside us. It is the epistemological manifestation of the problem of alienation. This dissertation is in two parts. The first part develops a notion of basic objectivity using the philosophy of Thomas Aquinas. The second part attempts to show the relationship between this notion of objectivity and the contemporary scientific methodology and world view, as interpreted in the works of Karl Popper. ;The key to (...) a basic objectivity lies in an experiential recognition that at the most fundamental level the self and the world are indistinguishable. The true "critical" question concerns, not bridging the gap, but an examination of the grounds for maintaining such a distinction. It terms of Thomistic psychology, objectivity can be considered a habit or disposition by which the self measures and is measured by the world in the mode of their common being. ;Many of the differences between Aquinas and Popper are terminological, historical, or due to different emphases of interest. A common language can best be established at the level of formal logic. Popper has worked his way out of many of the positions characteristic of the modern period and in fact, on several issues, stands closer to Aquinas than to most of his contemporaries. As compared to Aquinas, Popper's greatest deficiencies are poor technique in the art of defining, and the lack of a systematic utilization of the notion of principles. His main contributions are his emphasis on theory and on a methodology for the growth of conjectural knowledge. (shrink)
