Popper: Three Worlds

This paper aims to critically discuss the versatility of Popper’s theory of three worlds in the analysis of issues related to the ontological status and character of technical artifacts. Despite being discussed over years and hit with numerous criticisms it is still little known that Popper’s thesis has an important bearing on the philosophical characterization of technical artifacts. His key perspectives on the reality, autonomy, and ontological status of artifacts are rarely taken into consideration by scholars known to be engaged (...) in the study of artifacts. This paper consists of two main sections. The first section attempts to present a critical exposition of Popper’s account of reality and autonomy of artifacts. Recent discussions about the longstanding distinction between natural objects and artifacts are brought up and the relevance of Popper’s pluralistic thesis to this debate is pointed out. In addition, attention is drawn towards how to read his notion of the autonomy of artifacts. The primary emphasis of the second section is the ontological position of artifacts. Two separate arguments are posed to challenge the dual ontological status of what Popper called ‘embodied’ World 3 objects or artifacts. The first argument is concerned with the material composition and characteristic features of artifacts. The second one addresses the creative and epistemic value of these artificial products.

El artículo examina la idea popperiana del Mundo 3 como un caso de verdad práctica. El hecho de que Popper hable del conocimiento como de una habilidad práctica da pie a analizar su propuesta en los términos de la filosofía práctica de la ciencia, tal y como ha sido desarrollada por Alfredo Marcos. Este enfoque ofrece una visión más coherente del pensamiento popperiano en el que no cabría distinguir dos etapas incoherentes, una crítica y otra ontológica, sino un mismo pensamiento (...) en el que la relación entre sujeto y objeto de conocimiento no es tan simple como suponen el psicologismo subjetivista ni el objetivismo esencialista (extremos que Popper pretendió evitar siempre).

Ce texte vise à montrer les ressources variées de la thèse des trois mondes de Karl Popper dans l’analyse des questions liées au statut ontologique des artefacts matériels. Bien qu’elle ait été discutée depuis des années, et qu’elle ait fait l’objet de nombreuses critiques, on n’a presque pas remarqué que la thèse de Popper fournit d’excellentes idées pour la description philosophique des artefacts. Ce texte comprend deux sections. Dans la première, on donne un exposé critique des thèses de Popper quant (...) à la réalité et à l’autonomie (partielle) des artefacts. La seconde section présente deux arguments. Le premier se concentre sur la composition et les caractéristiques des artefacts matériels, et le second souligne leurs aspects créatifs et épistémiques.

This paper utilizes the framework of Karl Popper’s 3-world ontology to make the case that forensic science is a specialized coding system that establishes meaningful connections between the world of biology and the world of human society . Forensic science is a cross-disciplinary endeavor that uses scientific methods to determine what transpired in a crime so the legal system can determine how to prosecute the offender. On a Popperian analysis of forensic science, world 1 consists of evidence gathered at the (...) crime scene, which enables investigators to develop a detailed reconstruction of the incident for consideration under the legal and ethical codes of society, which are products of world 3. Understanding forensic science in this way serves two purposes: first, it extends Marcello Barbieri’s code biology into the realm of philosophical considerations in science, law and ethics; and second, it situates forensic science within the larger context of debates in contemporary philosophy of science.

The purpose of this article is to critically assess the ‘three-world theory’ as it is presented—with some slight but decisive differences—by Jürgen Habermas and Karl Popper. This theory presents the philosophy of science with a conceptual and material problem, insofar as it claims that science has no single access to all aspects of the world. Although I will try to demonstrate advantages of Popper’s idea of ‘the third world’ of ideas, the shortcomings of his ontological stance become visible from the (...) pragmatic point of view in Habermas’s theory of communicative acts. With regard to the critique that the three-world theory has met in both its pragmatic and ontological versions, I will take a closer look at John Searle’s naturalistic counter-position. By teasing out some problematic implications in his theory of causation, I aim to show that Searle’s approach is, in fact, much closer to Popper’s than he might think. Finally, while condoning Habermas’s distinction between the natural world and the lifeworld, I will opt for a pragmatically differentiated view of ‘the real’, rather than speaking of different worlds.

If we accept Popper's idea that the human habitat is described in terms of three worlds, and that there are overlaps between these three worlds, our moral actions and values will also be subject to the same kinds of consideration as a repertoire of behaviours exhibited in a physical environment. We will develop moral habits in a moral habitat and our moral behaviours will also be dependent on the kind of moral habitat in which we find ourselves. There are three (...) main problems to which this analysis leads and on which we will focus in this paper. Firstly, there is the problem of the kind of moral environment—habitat—that we need to provide for human beings if they are to develop the kinds of moral values that we hold to be important. Secondly, there is the question of how we are to develop the kinds of moral habits themselves and thirdly, there is the question of how these moral habits and habitat are to be maintained. If we take Popper seriously then human beings have a crucial responsibility in the creation of a moral third world—that is, a habitat in which human beings can flourish. Schools have an important role as a moral habitat for the inculcation of good moral habits. (shrink)

The first part of this paper is an attempt to offer an overview of Popper's World 3 in the light of philospher Rick Roderick's concerns about the growing excess of information in our times . The first part of the paper tries to place Roderick's important words of caution from "The Self under Siege" into the Popperian cosmology and to investigate the ways in which these views can be seen as fitting in Popper's World 3 framework. The second part of (...) the paper is the extension of one of the most famous World 3 thought experiments. This extension allows us to test some effects of the bearing on the human species as well as to explore the kind of fear that it causes. (shrink)

Este estudo abordará a tese dos três mundos, TTM, de Karl Popper. A TTM como pluralista e interacionista opõe-se ao monismo e a algumas concepções dualistas. Em uma segunda parte, pretendemos enfocar a crítica de Jürgen Habermas quando tenta aplicar a TTM e o M3 (mundo três) na obtençáo de uma justificaçáo da teoria da açáo para a sociologia. Nesta crítica Habermas acaba negligenciando muitos objetivos claros da TTM e do M3 descritos por Popper, principalmente quando náo considera a TTM (...) como uma tese metafísica e como resposta ao problema corpo-mente.

In the first part of the paper, the author presents Popper's theory of the objective knowledge and the three worlds in ten theses with a commentary, showing difficulties and vagueness of Popper's theory and trying to clarify it. The second part comprises discussion with a few Popper's theses. The author especially argues against the thesis about autonomy of the third world, and about epistemology limited to examination of only the objects from the third world. In relation to this, the author (...) shows some defects of Popper's argumentation from Objective Knowledge. The conclusion of the article is a different interpretation and an anew formulation of Popper's theory. (shrink)

Popper's thesis that the growth of knowledge lies in the emergence of problems out of criticism and takes place in an autonomous world of products of the human mind (his so-called world-3) raises two questions: (1) Why does criticism lead to new problems, and (2) Why can only a limited number of tentative solutions arise at a given time? I propose the following answer: Criticism entails an overlooked evolutionary world-3 mechanism, namely, the migration of piece meal conceptual schemes from one (...) research tradition to another. Popper by passed the questions above because he relied very heavily on the selective power of criticism. (shrink)

The problem addressed by this dissertation is the subject matter and methods of social science vis-a-vis the natural sciences and the humanities. It is commonly believed that the methodology of the social sciences is basically the same as that of the natural sciences, but that the subject matter--humanity--overlaps with the humanities. According to that view, the often-discussed gap between science and the humanities affects the social sciences as well. ;This project attempts to redirect our way of looking at this problem (...) by employing a number of strategies. First, it examines the issue as it has been explored by contemporary thinkers. Second, it describes the Verstehen method as employed by Max Weber, Karl Jaspers, and others. Third, it distinguishes between the pedagogical and research aspects of scientific theory and finds the former of unusual significance in the social sciences. That is because they are less tied to prediction and more to intuition than are the natural sciences. Fourth, it employs Karl Popper's Three Worlds metaphysics as a way of validating a revised Verstehen approach to the social sciences. ;The Three Worlds model holds that there are three components of reality: the physical world, the intrapsychic world, and the world of culture or objective knowledge. Aside from validating a verstehende social science, the aforementioned model helps to shed light on a number of contemporary issues in the social sciences including: the relationship between causal connections and meaningful connections, the meaning of "explanation," the interaction between mind and matter, the nature of probability and the nature of economics and other social sciences as disciplines. Despite its usefulness, however, the model is difficult for many to accept. ;The author approves of Popper's rejection of monism in favor of pluralism, but unlike Popper, he insists upon the uniqueness of social science. He also questions Popper's insistence on the lack of interaction between worlds 1 and 3. Like Popper, he rejects the notions of group minds or necessity in human history. Instead, he focuses on the role of individual freedom and consciousness as they interact with culture and uses Popper's model to focus our attention upon the significance of culture in the study of humanity. He views social science as running the gamut from natural science to the humanities and as the cornerstone of contemporary education because of its comprehensiveness in comparison with the natural sciences and the humanities. This will be seen to have far-reaching significance not only for the development of social science research, but for pedagogical and other practical applications as well, despite the fact that the project generally steers clear of value-laden issues. Nevertheless, it affirms the need for axiological and faith commitments for human flourishing. (shrink)

THE MIND-BODY PROBLEM: A GUIDE TO THE CURRENT DEBATE (EDITED BY RICHARD WARNER AND TA D E U S Z SZUBKA) contains recent essays by the key players in the the field of the Mind-Body problem: Searle, Fodor, Problem Honderich, Nagel, McGinn, Stich, Rorty and others. But there are a few interesting exceptions, for example Edelman, Popper, Putnam and Dennett. Nevertheless, these thinkers do get a mention here and there, and nearly all the exciting topical issues are dealt with, including (...) externalism, functionalism, intentionality, Turing computational models, and the relationship between these philosophical problems and psychology. I am particularly struck by the tendency to engage in an evasive stratagem when it comes to stating the physicalist thesis. Instead of a clear definitive position about what kind of physical science would achieve the hoped-for reduction, what I found was variations on Lewis's claim that the reduction would be effected by a "unified body of scientific theories of the sort we now accept". Materialism used to be a clear doctrine: a clockwork Universe of impenetrable particles. But materialism transcended itself. First through Hobbes' and Leibniz's criticisms of Descartes, then Newton's demolition of the Cartesian idea that matter was essentially extension by introducing gravity (action at a distance) and then through the field theories of Faraday and Maxwell, and more recently through Einstein's work, which undermined the "substance" view of matter, something that remained permanent while other changes occurred. I contrast the perspectives of the Churchlands with those of Donald T. Campbell, Karl Popper and other evolutionary and emergentist views. -/- . (shrink)

Popper's third world includes a variety of contents of scientific, poetical, and philosophical thought, as well as standards and values. This heterogeneous construction has been associated by Popper with Frege's drittes Reich. The author discussed the problem of legitimizing such a comparison.

Abstract This paper aims to analyse Karl Popper's conception of ?three worlds?, and especially the problem of world 3?the world of objective knowledge. Firstly, I try to explain Popper's turn to ontological questions which I link to his antipsychologism and to issues raised by the development of logic after World War II. I then consider Popper's concept of the autonomy of world 3 and his attempt to introduce world 3 as a world of knowledge without a knowing subject. I conclude (...) that Popper did not succeed in unifying his central idea of autonomy of knowledge with the requirement of the creative role of the critical subject carrying out the evolution of knowledge. I see the core of this contradiction especially in his co?existing ideas of the timeless existence of world 3 and the elimination of the subject from it. The attempt to desubjectivize the realm of objective knowledge leads to a philosophically unbalanced standpoint which presupposes a creative subject and at the same time neglects it. Finally, I question Popper's account of the growth of world 3. Popper considers only cognitive motivations, and excludes a broad range of motivating factors which originate in the problems which we face in our lives, and affect our cognitive interests in world 3.

Popper suggests human thought and ideas exist in a world of their own, transcending our thought processes and the material world. Theories, and other human ideological creations such as values, institutions and works of art, develop independently of those who work on them, and have a causal effect on them. What Popper suggests in support of his Platonism does not show that our theories are autonomous in any non trivial way. Also the picture of an abstract world of ideas causally (...) affecting our thought processes is fraught with difficulty. (shrink)

Popper’s three world doctrine, it has been argued by Peyerahend and Krige, is a rejection of the type of critical dualism of facts and norms articulated in The Open Society. Peyerabend argues further that world 3 acts as a methodological prison designed to restrict the free decision of the individual theoretical scientist. It is my position that Popper's concept of world 3 is not a rejection of critical dualism but rather an attempt to allow for the existence of free normative (...) decisions within the context of a binding tradition. The key to understanding this move is the notion of an objective norm. Specifically I argue that Popper's pluralistic epistemology is based on a traditional many-levelled semantics developed originally to combat psychologism and used now to place the issue of the choice of methodological norms within the framework of a theory of tradition.
