An analysis of the theory of biodynamic farming is presented. The founder of biological dynamic agriculture, the Austrian Rudolf Steiner, Ph.D., (1861–1925), introduced methods of preparation and use of eight compounds forming the nucleus of his agricultural theory. His instructions were based on insights and inner visions from spiritualistic exercises and not on agricultural experiments. His purpose was to show mankind a form of agriculture that enables not only the production of healthy foods but also the achievement of harmonious interactions (...) in agriculture and a spiritual development of mankind through “cosmic forces” captured in the foods. However, many of his statements are not provable simply because scientifically clear hypotheses cannot be made as his descriptions were unclear and not stringent. Those predictions that can be tested scientifically have been found to be incorrect. It was concluded that Steiner's instructions are occult and dogmatic and cannot contribute to the development of alternative or sustainable agriculture. (shrink)

In this paper, we propose a regularity theory of causation. The theory aims to be reductive and to align with our pre‐theoretic understanding of the causal relation. We show that our theory can account for a wide range of causal scenarios, including isomorphic scenarios, omissions, and scenarios which suggest that causation is not transitive.

Proponents of mechanistic explanations have recently proclaimed that all explanations in the neurosciences appeal to mechanisms. The purpose of the paper is to critically assess this statement and to develop an integrative account that connects a large range of both mechanistic and dynamical explanations. I develop and defend four theses about the relationship between dynamical and mechanistic explanations: that dynamical explanations are structurally grounded, that they are multiply realizable, possess realizing mechanisms and provide a powerful top-down heuristic. Four examples shall (...) support my points: the harmonic oscillator, the Haken–Kelso–Bunz model of bimanual coordination, the Watt governor and the Gierer–Meinhardt model of biological pattern formation. I also develop the picture of “horizontal” and “vertical” directions of explanations to illustrate the different perspectives of the dynamical and mechanistic approach as well as their potential integration by means of intersection points.

We define a formal semantics of conditionals based on _normatively ideal worlds_. Such worlds are described informally by Armgardt (Gabbay D, Magnani L, Park W, Pietarinen A-V (eds) Natural arguments: a tribute to john woods, College Publications, London, pp 699–708, 2018) to address well-known problems of the counterfactual approach to causation. Drawing on Armgardt’s proposal, we use iterated conditionals in order to analyse causal relations in scenarios of multi-agent interaction. This results in a refined counterfactual approach to causal responsibility in (...) legal contexts, which solves overdetermination problems in an intuitively accessible manner. (shrink)

This article presents research into human mental spatial reasoning with orientation knowledge. In particular, we look at reasoning problems about cardinal directions that possess multiple valid solutions , at human preferences for some of these solutions, and at representational and procedural factors that lead to such preferences. The article presents, first, a discussion of existing, related conceptual and computational approaches; second, results of empirical research into the solution preferences that human reasoners actually have; and, third, a novel computational model that (...) relies on a parsimonious and flexible spatio-analogical knowledge representation structure to robustly reproduce the behavior observed with human reasoners.

We put forth an analysis of causation. The analysis centers on the notion of a causal model that provides only partial information as to which events occur, but complete information about the dependences between the events. The basic idea is this: an event causes another just in case there is a causal model that is uninformative on both events and in which the first event makes a difference as to the occurrence of the other. We show that our analysis captures (...) more causal scenarios than the other counterfactual accounts to date. (shrink)

Drawing on recent work in developmental and comparative psychology, this paper argues that demonstratives function to coordinate the interlocutors' joint focus of attention, which is one of the most basic functions of human communication. The communicative importance of demonstratives is reflected in a number of properties that together characterize them as a particular word class: In contrast to other closed-class expressions, demonstratives are universal, they are generally so old that their roots cannot be traced back to other linguistic items, they (...) are among the earliest words that children learn, and they are closely tied to a particular gesture. Moreover, demonstratives play an important role in the organization of discourse and the diachronic evolution of grammar, which arguably is also motivated by their communicative function to establish joint attention.

In der Debatte um den wissenschaftlichen Realismus gewinnt zunehmend der Strukturenrealismus - dessen Auffassung zufolge der Realgehalt wissenschaftlicher Theorien in deren mathematisch-logischer Struktur liegt - an Bedeutung. Die vorliegende Arbeit untersucht diese These anhand der in unserer fundamentalen Physik bedeutsamsten Klasse von Theorien, den Eichtheorien, die durch spezielle lokale Symmetriestrukturen gekennzeichnet sind. Die Arbeit bietet dem Leser in ihren ersten Kapiteln einen Einstieg in die zentralen Themen Symmetrien, wissenschaftlicher Realismus und Eichtheorien. In den im Mittelteil durchgeführten Analysen werden Quanten- und (...) Gravitations-Eichtheorien in konzeptioneller Hinsicht - vor allem bezüglich der zugrundeliegenden Prinzipien - und ontologischer Hinsicht - mit Blick auf die Unterbestimmtheit der Entitäten und verschiedener Lokalitätsannahmen - im Detail untersucht. Resultierend ergibt sich eine Stützung des Strukturenrealismus, jedoch nicht in dessen radikaler ontischer Variante, sondern in der moderateren epistemischen oder allenfalls intermediären Spielart, bei der sowohl Strukturen als auch deren Träger existieren, wobei letzterer jedoch amorph und und mithin epistemisch unverfügbar ist.

We aim to devise a Ramsey test analysis of actual causation. Our method is to define a strengthened Ramsey test for causal models. Unlike the accounts of Halpern and Pearl ([2005]) and Halpern ([2015]), the resulting analysis deals satisfactorily with both over- determination and conjunctive scenarios.

The paper looks at the intersection of extended cognition and social cognition. The central claim is that the mechanisms of shared intentionality can equally be considered as coupling mechanisms of cognitive extension into the social domain. This claim will be demonstrated by investigating a detailed example of cooperative action, and it will be argued that such cases imply that socially extended cognition is not only about cognitive vehicles, but that content must additionally to be taken into account. It is finally (...) outlined how social content externalism can in principle be grounded in socially extended cognition. (shrink)

In this paper, we analyse actual causation in terms of production. The latter concept is made precise by a strengthened Ramsey Test semantics of conditionals: \ iff, after suspending judgement about A and C, C is believed in the course of assuming A. This test allows us to verify or falsify that an event brings about another event. Complementing the concept of production by a weak condition of difference-making gives rise to a full-fledged analysis of causation.

The aim of this paper is to scrutinize active externalism and its repercussions for externalism about mental content. I start from the claim that active externalism is a version of content externalism that follows from the extended cognition thesis as a thesis about cognitive vehicles. Various features of active content externalism are explored by comparison with the known forms of passive externalism – in particular with respect to the multiple realizability of the relevant external content-determining components and with respect to (...) mental causation. A crucial result is that social externalism is already a version of active externalism. I conclude with a first sketch of a general account of meaning inspired by extended cognition: a use theory supplemented by a functional-role account. (shrink)

The well-known formal semantics of conditionals due to Stalnaker Studies in logical theory, Blackwell, Oxford, 1968), Lewis, and Gärdenfors The logic and 1140 epistemology of scientific change, North-Holland, Amsterdam, 1978, Knowledge in flux, MIT Press, Cambridge, 1988) all fail to distinguish between trivially and nontrivially true indicative conditionals. This problem has been addressed by Rott :345–370, 1986) in terms of a strengthened Ramsey Test. In this paper, we refine Rott’s strengthened Ramsey Test and the corresponding analysis of explanatory relations. We (...) show that our final analysis captures the presumed asymmetry between explanans and explanandum much better than Rott’s original analysis. (shrink)

The program of “neurophenomenal structuralism” is presented as an agenda for a genuine structuralist neuroscience of consciousness that seeks to understand specific phenomenal experiences as strictly relational affairs. The paper covers a broad range of topics. It starts from considerations about neural change detection and relational coding that motivate a solution of the Newman problem of the brain in terms of spatiotemporal relations. Next, phenomenal quality spaces and their Q-structures are discussed. Neurophenomenal structuralism proclaims a homomorphic mapping of the structures (...) of self-organized neural maps in the brain onto Q-structures, and it will be demonstrated how this leads to a new and special version of structural representationalism about phenomenal content. A methodological implication of neurophenomenal structuralism is that it proposes measurement procedures that focus on the relationships between different stimuli (as, for instance, similarity ratings or representational geometry methods). Finally, it will be shown that neurophenomenal structuralism also has strong philosophical implications, as it leads to holism about phenomenal experiences and serves to reject inverted qualia scenarios.

Background: Informed consent is a legal as well as ethical prerequisite in clinical research. For dementia research, informed consent can be a problem if subjects with dementia, whose capacity for understanding and thus also decision making might be limited, are to be exam- ined. This might result in exclusion of dementia patients from research, as capacity for understanding and decision making are often equated with the ability for rational decision making. However, this valuation has been criticized at times for attaching (...) too much impor- tance to the cognitive aspect of decision making. -/- Methods: This qualitative study investigates the actual consent procedure of a clini- cal research study in Germany with regard to dementia patients’ subjective and objective understanding of informed consent information. Research participants were ten dementia patients, who volunteered in two clinical research studies, as well as their caregivers. Data were collected by use of semi-structured interviews. -/- Results: It was determined that the patients’ comprehension of informed consent infor- mation was rather limited. However, a number of patients were quite aware of this. In con- trast, all caregivers claimed to have fully understood the provided information, while their objective comprehension was also incomplete. Several participants indicated that they did not attach much importance to the information given in the consent procedure and that their consent did not primarily depend on this information. Rather, participation in the research study for them seemed to be more of a problem-focused coping strategy for dealing with their diagnosis of dementia. -/- Conclusion: For research ethics these results raise the question whether the currently prevailing emphasis on the cognitive aspect of autonomous decision making, i.e., compre- hension, may be too one-sided, and to what extent the “volitional” aspect in giving consent should be given greater consideration.

The paper has three parts. In the first part ExtOSR, an extended version of Ontic Structural Realism, will be introduced. ExtOSR considers structural properties as ontological primitives, where structural properties are understood as comprising both relational and structurally derived intrinsic properties or structure invariants. It is argued that ExtOSR is best suited to accommodate gauge symmetry invariants and zero value properties. In the second part, ExtOSR will be given a Humean shape by considering structures as categorical and global. It will (...) be laid out how such structures serve to reconstruct non-essential structural kinds and laws. In the third part Humean structural realism will be defended against the threat of quidditism. (shrink)

This book aims to lay bare the logical foundations of tractable reasoning. It draws on Marvin Minsky's seminal work on frames, which has been highly influential in computer science and, to a lesser extent, in cognitive science. Only very few people have explored ideas about frames in logic, which is why the investigation in this book breaks new ground. The apparent intractability of dynamic, inferential reasoning is an unsolved problem in both cognitive science and logic-oriented artificial intelligence. By means of (...) a logical investigation of frames and frame concepts, Andreas devises a novel logic of tractable reasoning, called frame logic. Moreover, he devises a novel belief revision scheme, which is tractable for frame logic. These tractability results shed new light on our logical and cognitive means to carry out dynamic, inferential reasoning. Modularity remains central for tractability, and so the author sets forth a logical variant of the massive modularity hypothesis in cognitive science. (shrink)

Previous studies have shown that multiple reference frames are available and compete for selection during the use of spatial terms such as “above.” However, the mechanisms that underlie the selection process are poorly understood. In the current paper we present two experiments and a comparison of three computational models of selection to shed further light on the nature of reference frame selection. The three models are drawn from different areas of human cognition, and we assess whether they may be applied (...) to a reference frame selection by examining their ability to account for both existing and new empirical data comprising acceptance rates, response times, and response time distributions. These three models are the competitive shunting model, the leaky competing accumulator model, and a lexical selection model. Model simulations show that only the LCA model satisfactorily accounts for the empirical observations. The key properties of this model that seem to drive its success are its bounded linear activation function, its number and type of processing stages, and its use of decay. Uncovering these critical properties has important implications for our understanding not only of spatial term use, in particular, but also of conflict and selection in human cognition more generally.

English summary: In this volume, Holger Gutschmidt has gathered together several studies on the concept of the idea and its relationship to the notion of justification in selected 17th century theories. His main focus is on the philosophy of Rene Descartes, who introduced the concept of the idea into modern epistemology. He devotes further chapters to Antoine Arnauld as well as to the logic of Port Royal, Spinoza, and finally Leibniz. The study of the concept of the idea in (...) the context of its function within theories of knowledge and justification has brought about a series of new research results as well as corrections to existing research. German description: Holger Gutschmidt versammelt in diesem Band mehrere Untersuchungen zur Konzeption der Idee und ihrer Beziehung zum Begrundungsbegriff in ausgewahlten Theorien des 17. Jahrhunderts. Sein Hauptaugenmerk liegt auf der Philosophie Rene Descartes', der den Ideenbegriff in die neuzeitliche Erkenntnistheorie einfuhrt. Weitere Kapitel widmet er Antoine Arnauld sowie der Logik von Port Royal, Spinoza und schliesslich Leibniz. Die Untersuchung der Ideenkonzeption vor dem Hintergrund ihrer Funktion in den jeweiligen Theorien der Erkenntnis und der Begrundung fuhrt zu einer Reihe von neuen Forschungsresultaten und Korrekturen der bisherigen Forschungssituation. Der Autor beschaftigt sich unter anderem mit dem Thema der von Descartes eingefuhrten sogenannten objektiven Ideen, dem Verhaltnis von Idee und Begriff, der Seinsart von Ideen, der Funktion der Idee von Gott, dem direkten Realismus.

Platonic Patterns is a reprint collection of many of Holger Thesleff's studies in Plato—spanning from 1967 to 2003. It includes three books, four articles and a new introduction by the author, which sets the general outline of his interpretation of Plato. Whereas much of the scholarship on Plato has tended to operate within the frame of one language and/or a single school of thought, Thesleff constructively combines several discoveries and theories of various scholars with his own research, focusing on (...) how Plato can be understood in his own context. The work represents small but significant breakthroughs in research on Plato from an internationally inclusive standpoint. Having previously been published mainly in Finland by scholarly societies, availability outside the Nordic countries has, up until now, been minimal. Thesleff employs his singular expertise of Greek language and literature to make innovative contributions to the study and interpretation of Plato. He thematically stresses the significance of the less overt elements found in Plato's dialogues, such as Plato's use of humor and his linguistic expression, while taking into account the chronology and/or the intended audience.

Did Goethe devise an empirically viable theory of classical ray optics? Or can we at least make use of his ideas to propose one? And if so, does this confront us with an intriguing case of theory underdetermination? In this paper, which is mainly a comment on the recent work of Olaf Müller, I shall address these three questions and argue for ‘no, yes, no’. This is in contrast to Müller, who has recently launched a vivid defense of Goethe-style ray (...) optics :569–573, 2015b; Z Philos Forsch 69:588–598, 2015c; Br J Hist Philos 24:322–346, 2016). Müller aims to give an almost positive answer to all three questions: ‘perhaps, yes, yes’. My overall line of argument will be that the rather restricted regime of classical geometrical optics of spectral colors allows at best for a weak form of transient theory underdetermination that, in turn and more straightforwardly, also allows for a structuralist reading in terms of two structurally equivalent formulations of one and the same theory. However, extending any of the rivaling models of ray optics other than Newton’s beyond the mentioned regime and embedding them into physics in total—especially in view of thermodynamics—leads to a contradiction. Hence, Newton’s theory is confirmed as the only consistent theoretical interpretation of ray optics. (shrink)
