This book is about Karl Popper's early writings before he began his career as a philosopher. The purpose of the book is to demonstrate that Popper's philosophy of science, with its emphasis on the method of trial and error, is largely based on the psychology of Otto Selz, whose theory of problem solving and scientific discovery laid the foundation for much of contemporary cognitive psychology. By arguing that Popper's famous defence of the method of falsification as well as his elaboration (...) of an evolutionary theory of knowledge are equally indebted to German psychology, Michel ter Hark challenges the received view of the development of Popper's philosophy. The book concludes with a reinterpretation of Popper's theory of the mind-body problem, emphasizing its contemporary relevance. (shrink)

On the basis of his unpublished thesis ‘Gewohnheit und Gesetzerlebnis in der Erziehung’ a historical reconstruction is given of the genesis of Popper's ideas on induction and demarcation which differs radically from his own account in Unended quest. It is shown not only that he wholeheartedly endorses inductive epistemology and psychology but also that his ‘demarcation’ criterion is inductivistic. Moreover it is shown that his later demarcation thesis arises not from his worries about, on the one hand, Marxism and psychoanalysis (...) and, on the other hand, Einstein's physics, but rather from his urgent preoccupation with providing pedagogy with a psychological foundation, which has its sources in Karl Bühler's cognitive psychology as well as, surprisingly, Adler's Characterology. Aside from Adler some lesser known psychologists, such as Karl Groos, will also be seen to have played a formative role on Popper's early thinking. (shrink)

The aim of this article is to show that one of Popper's key ideas in epistemology, his so-called theory of the searchlight, is derived from early German Denkpsychologie, in particular the theory of schematic anticipations of Otto Selz. With his theory of schematic anticipations Selz intended to replace various forms of association psychology. Likewise Popper's theory of the searchlight aims to replace empiricism in epistemology (the Bucket theory, as he calls it). On the basis of Popper's still unpublished manuscripts on (...) psychology between 1927 and 1931, it is shown that his position became increasingly Selzian. The term "Bucket theory" is used by him for the first time in an article in which he defends Selz, and in his earlier Ph.D. thesis there occur passages which show him in complete agreement with the theory of schematic anticipations. It is argued that Popper's Selzian stance in psychology finally enabled him to develop his characteristic deductive stance in epistemology and philosophy of science. It is also emphasized that Popper never credits Selz for this formative role. (shrink)

This essay sketches the potential implications of Wittgensteinian thought for conceptualizations of socalled fictive mental states, e.g. mental calculating, imagination, pretend play, as they are currently discussed in developmental psychology and philosophy of mind. In developmental psychology the young child's pretend play and make-belief are seen as a manifestation of the command of an underlying individualistic “theory of mind”. When saying “This banana is a telephone” the child's mind entertains simultaneously two mental representations, a primary or veridical representation about the (...) real properties of banana's and a pretend representation. It is the task of psychology to explain how this “double knowledge” does not result in conceptual chaos. Various sorts of internal mechanisms are postulated. In this essay it is argued that the threat of chaos is misconceived, and that the solutions are irrelevant. Following Wittgenstein's sparse remarks about the secondary sense of words, I argue that pretend language does not refer to underlying individual mental representations but to the child's creative transference of words used in one, primary, domain of application to another, secondary domain. The command and use of the secondary domain logically presupposes the command and use of the primary domain. Since the latter domain is necessarily public and social, fictive mental states cannot be dealt with purely individualistically as current mentalism assumes. (shrink)

The idea that we acquire knowledge by trial and error has been one of the truly great ideas of the twentieth century. As no reader of his philosophical and autobiographical work could have failed to notice, Karl Popper credits himself for having invented this idea. The theory of trial and error or, in Popper's words, the Searchlight theory of knowledge and mind, is not just a part of Popper's comprehensive philosophy but rather one of its key features. It is at (...) the bottom of some of his most spectacular achievements in methodology, epistemology, the philosophy of biology, and even political philosophy. Indeed, it is put forward at once as a model for the growth of individual knowledge (both human and animal), the growth of life (Darwin's theory of evolution), and the growth of scientific knowledge (philosophy of science). As happens so often with innovative ideas, the Searchlight theory derives much of its glamour from the theory it rejects: the view of the mind being a tabula rasa and sense perception the origin of all (human) knowledge. Popper nicknames this empiricists' view as the Bucket theory since it conceives of the mind as nothing but the conduit for sense-impressions, an empty bucket to be filled by the accumulation and storage of information. 1 In his hands the Bucket theory collapses under the strain of philosophical arguments and scientific facts and is replaced by a theory which maintains that our knowledge of the physical world is drawn from our mind and constructed from the repertoire of knowledge dispositions we already possess. Acquiring dispositions proceeds according to the method of trial and error elimination. This method, Popper contends, consists essentially of three stages: forming a problem or expectation, trying out a number of solutions of the problem, and eliminating or discarding false solutions as erroneous. 2 A key feature of Popper's theory of trial and error elimination, and the reason for speaking of a Searchlight theory of knowledge and mind, is his insistence that problems or expectations take precedence over observations. Observations are always preceded by expectations, points of view, questions or problems which, as a searchlight, illuminate a certain area, thereby enabling the organism or the scientist to know what to observe in the first place. -/- The question arises how and when did Popper come to this theory of the growth of knowledge and mind which was to have such radical implications for the philosophy of science, epistemology, and the philosophy of psychology? My aim in this article is to trace the roots of his theory of the Searchlight. The earliest traces of the theory are to be found in his unpublished dissertation, Zur Methodenfrage der Cognitive psychology (1928). Here I will focus upon this "hasty last minute affair" written in the tradition of early German cognitive psychology and supervised by one of its most outstanding proponents, Karl Bühler. Scrutiny of this manuscript, however, reveals not so much the formative influence of Bühler as that of Otto Selz. Indeed, I will argue that Popper borrowed his crucially important Searchlight theory from Selz. Thus having found the origin of the key notion of his epistemology in psychology, the relation between psychology and philosophy in Popper's work, always fraught with tension, is up for thorough reconsideration.

How does the philosophical problem about mental processes and states and behaviourism arise?—The first step is the one that altogether escapes notice. We talk of processes and states and leave their nature undecided. Sometimes perhaps we shall know more about them—we think. But that is just what commits us to a particular way of looking at the matter. And now the analogy which was to make us understand our thoughts falls to pieces. So we have to deny the yet uncomprehended (...) process in the yet unexplored medium. And now it looks as if we had denied mental processes. And naturally we don’t want to deny them. (shrink)

This chapter focuses on sections iv and v of part II of Wittgenstein’s Philosophical Investigations. In these sections Wittgenstein deals with two closely knit problems: our knowledge of other minds and the subject matter of psychology. The interpretation of Wittgenstein’s treatment of these problems cannot remain confined to these sections, however, as equally important references to these problems occur elsewhere in the Investigations as well as in the Remarks on the Philosophy of Psychology. Moreover, Wittgenstein’s very treatment of the two (...) problems is intertwined with his treatment of some other problems in the philosophy of psychology. For instance, in the context of his discussion of the subject matter of psychology, he points out analogies with problems pertaining to theories of perception. I take these analogies seriously and, therefore, a discussion of perception is interwoven as appropriately. Yet another preliminary remark. Although references to other philosophers and psychologists do not occur in sections iv and v, it does not follow that they were not written in response to others. On the contrary, a substantial part of these (and other) sections is the product of reflecting upon theories produced by Russell, James and Köhler. In my view, the best way to understand Wittgenstein is to involve the standpoints of his adversaries explicitly into the discussion. Otherwise seemingly trivial questions and condensed remarks, gain power and depth when explicitly seen as undermining and reversing dominant theories in philosophy and psychology. (shrink)

The aim of this article is to give both a sustained interpretation of Wittgenstein’s obscure remarks on the experience of meaning of language, synthaesthesia and secondary use and to apply his insights to recent philosophical discussions about synthaesthesia. I argue that synthaesthesia and experience of meaning are conceptually related to aspect-seeing. The concept of aspect-seeing is not reducible to either seeing or imaging but involves a modified notion of experience. Likewise, synthaesthesia involves a modified notion of experience. In particular, the (...) concept of synthaesthesia involves a secondary use of ‘experience’ and hence is intrinsically dependent on the primary use of language. Recent discussions tend to overlook this distinction between the primary and secondary use of language. (shrink)

In this article it is argued that Popper's well-known deductive and falsificationistic epistemology is historically rooted in German psychology, notably the work of Otto Selz. Drawing on Popper's early and still unpublished psychological manuscripts it is shown how Otto Selz's psychology of thinking with its emphasis on the guiding role of schematic anticipations gave the impetus to Popper's theory of problem solving, his theory of the Searchlight, and its attendant rejection of empiricism, the so-called Bucket theory of knowledge. In the (...) second part of the article it is argued that Selz's theory of schematic anticipations is rooted in Meinong's Gegenstandstheorie. Because Meinong's theory was partly an attempt to do justice to the objectivity of thinking, this may explain why the anti-psychologist Popper felt nevertheless attracted to the psychology of Selz.

This paper discusses a neglected theme in Wittgenstein’s writings on meaning and psychology from the early 1930s until 1949. Throughout this period Wittgenstein deals with aspects of meaning of words and pictures that cannot be accounted for in dispositional terms but have to be related to experience and perception. Wittgenstein’s reading of William James, I argue, has sharpened his eye for the many pitfalls in coming to terms with this experiential notion of meaning. James’s treatment of experiences of meaning succumbs (...) to the temptation to postulate “meaning-bodies,” bearers of meaning apart from the way and context in which we use the particular words. I argue that the conflation of what Wittgenstein calls the transitive and intransitive use of words is at the root of postulating meaning-bodies. I also argue that contemporary treatments of experiences of meaning are similarly vulnerable to James’s confusion. (shrink)

“Tell me," Wittgenstein once asked a friend, "why do people always say, it was natural for man to assume that the sun went round the earth rather than that the earth was rotating?" His friend replied, "Well, obviously because it just looks as though the Sun is going round the Earth." Wittgenstein replied, "Well, what would it have looked like if it had looked as though the Earth was rotating?” What would it have looked like if we looked at all (...) sciences from the viewpoint of Wittgenstein’s philosophy? Wittgenstein is undoubtedly one of the most influential philosophers of the twentieth century. His complex body of work has been analysed by numerous scholars, from mathematicians and physicists, to philosophers, linguists, and beyond. This volume brings together some of his central perspectives as applied to the modern sciences and studies the influence they may have on the thought processes underlying science and on the world view it engenders. The contributions stem from leading scholars in philosophy, mathematics, physics, economics, psychology and human sciences; all of them have written in an accessible style that demands little specialist knowledge, whilst clearly portraying and discussing the deep issues at hand.

What does it mean to write "This is not a pipe" across a bluntly literal painting of a pipe? René Magritte's famous canvas provides the starting point for a delightful homage by French philosopher and historian Michel Foucault. Much better known for his incisive and mordant explorations of power and social exclusion, Foucault here assumes a more playful stance. By exploring the nuances and ambiguities of Magritte's visual critique of language, he finds the painter less removed than previously thought (...) from the pioneers of modern abstraction. (shrink)

Michel de Montaigne, the inventor of the essay, has always been acknowledged as a great literary figure but has never been thought of as a philosophical original. This book treats Montaigne as a serious thinker in his own right, taking as its point of departure Montaigne's description of himself as 'an unpremeditated and accidental philosopher'. Whereas previous commentators have treated Montaigne's Essays as embodying a scepticism harking back to classical sources, Ann Hartle offers an account that reveals Montaigne's thought (...) to be dialectical, transforming sceptical doubt into wonder at the most familiar aspects of life. This major reassessment of a much admired but also much underestimated thinker will interest a wide range of historians of philosophy as well as scholars in comparative literature, French studies and the history of ideas.

It is widely agreed that fiction is necessarily incomplete, but some recent work postulates the existence of universal fictions—stories according to which everything is true. Building such a story is supposedly straightforward: authors can either assert that everything is true in their story, define a complement function that does the assertoric work for them, or, most compellingly, write a story combining a contradiction with the principle of explosion. The case for universal fictions thus turns on the intuitive priority we assign (...) to the law of non-contradiction. My goal in this paper is to show that our critical and reflective literary practices set constraints on story-telling which preclude universal fictions. I will raise four stumbling blocks for universal fictionalists: the gap between saying and making true, our actual interpretive reactions to story-level contradictions, the criteria we accept for what counts as a story in our literary practices, and the undesirability of the universal fictionalist’s closure principles.

The premise that every work belongs to an art-kind has recently inspired a kind-centred approach to theories of art. Kind-centred analyses posit that we should abandon the project of giving a general theory of art and focus instead on giving theories of the arts. The main difficulty, however, is to explain what makes a given kind an art-kind in the first place. Kind-centred theorists have passed this buck on to appreciative practices, but this move proves unsatisfactory. I argue that the (...) root of this dissatisfaction stems not from the act of kicking the can down the road, but from not kicking it far enough. The missing ingredient, I argue, is a notion of convention which does the work of marking the difference between art and non-art for a given physical medium. (shrink)

It is widely believed, among philosophers of literature, that imagining contradictions is as easy as telling or reading a story with contradictory content. Italo Calvino’s The Nonexistent Knight, for instance, concerns a knight who performs many brave deeds, but who does not exist. Anything at all, they argue, can be true in a story, including contradictions and other impossibilia. While most will readily concede that we cannot objectually imagine contradictions, they nevertheless insist that we can propositionally imagine them, and regularly (...) do, simply by entertaining a text which prompts us to do so. I argue that this narrative does not bear scrutiny for two main reasons. First, because propositional imagining is beside the point, where truth in fiction is concerned; evaluating truth in fiction engages the cognitive architecture in ways that prohibit the mobilization of merely propositional imagination to that end. And second, because it is not obvious, given the strategies usually suggested, that we ever propositionally imagine contradictions in the first place—in fact, it seems we go out of our way to avoid directly imagining them.

Schopenhauer’s invective is legendary among philosophers, and is unmatched in the historical canon. But these complaints are themselves worthy of careful consideration: they are rooted in Schopenhauer’s philosophy of language, which itself reflects the structure of his metaphysics. This short chapter argues that Schopenhauer’s vitriol rewards philosophical attention; not because it expresses his critical take on Fichte, Hegel, Herbart, Schelling, and Schleiermacher, but because it neatly illustrates his philosophy of language. Schopenhauer’s epithets are not merely spiteful slurs; instead, they reflect (...) deep-seated theoretical and methodological commitments to transparency of exposition. (shrink)

‘Philosophical dialogue’ indicates both a form of philosophical inquiry and its corresponding literary genre. In its written form, it typically features two or more characters who engage in a discussion concerning morals, knowledge, as well as a variety of topics that can be widely labelled as ‘philosophical’. Our philosophical dialogue takes place in Krakow, Poland. It is a rainy morning and two strangers are waiting at a tram stop. One of them is dressed neatly, and cannot stop fidgeting with his (...) closed umbrella. The other was caught unprepared by the morning downpour and water is dripping from his worn, soaked jacket.
