The paper takes a fresh look at two essays that Adam Smith wrote at the very beginning of his career. In these essays, Smith explains his philosophy of science, which is social constructivist. A social constructivist reading of Smith strengthens the scholarly consensus that The Wealth of Nations needs to be interpreted in light of the general moral theory he explicates in The Theory of Moral Sentiments, as the two essays and TMS stress the importance of the same concepts: e.g., (...) moral imagination, the socially embedded individual, and humility. The connecting tissue between all three works is made up of sentiments and values. Smith regards the socially embedded human as the agent in all three realms, and humans are always driven by values. Smith not only conceives of economics as an applied moral philosophy, but also bases both research areas on a view of knowledge creation that stresses specific epistemic values. If mainstream economic theory wants to have any claim to Adam Smith, it would have to change not only what it argues but also how it argues. Economists would have to replace the language of mathematics with the language and logic of moral philosophy and give values centre stage. (shrink)

In both the public and the business world, in academe as well as in practice, the ideas of Adam Smith are regarded as the bedrock of modern economics. When present economic conditions and management practices are criticised, Adam Smith is referred to by defenders and detractors of the current status quo alike. Smith, it is believed, defined the essential terms of reference of these debates, such as the rational pursuit of self-interest on part of the individual and the resultant optimal (...) allocation of goods in free markets thanks to the workings of an “invisible hand.” In this article, we question whether this standard view of Smith, the economist, is tenable. We provide an extensive review of the extant secondary literature from economists, business ethicists, and philosophers, comparing their assessments to crucial elements of Smith’s theoretical system. As a result, we show that Smith, far from being an advocate of a value-free or even value-averse conception of economic transactions, stood for a virtue-based and values-oriented model of business. Accordingly, we argue current management education and the pedagogy of business ethics ought to be changed, and certain strategic conclusions drawn for business practice. (shrink)

In the leadership literature of the past 100 years or so, rhetoric has been a topic for a long time and ethics was introduced some 30 years ago. However, the three topics, leadership, rhetoric, and ethics, have not been connected. This is astonishing because when ethical leadership made its comeback, scholars acknowledged the debt that ethical leadership owes to Aristotelian ideas. For Aristotle, leadership, ethics, and rhetoric were inseparable: without ethics, there could neither be good leadership nor rhetoric, and rhetoric (...) was the bridge from leader to follower and back. Aristotle is known as the practical philosopher and we argue that closing this major lacuna in leadership theory, would be beneficial for practice too and would help prevent Theranos-like scandals. The lacuna lies in what some call a Machiavellian view of leadership and rhetoric: both are regarded as amoral tools to achieve given ends. Aristotle would bristle at that idea. Both, leadership and rhetoric, to be good, must aim at the noble. The noble is not dictated by a heroic despot nor by a selfless saint but is understood by a leader because s/he is a socially embedded individual. We argue that leadership should be understood as personal development, that organisational rules must not inhibit virtue, that leadership is more about listening than talking, that synthesising that which is heard is central, and finally, that the common, not the collective, good is the goal of leadership.

This paper argues that economics, over the past 200 years, has become steadily more anti-philosophical and that there are three stages in the development of economic thought. Adam Smith intended economics to be a descriptive social science, rooted in an understanding of the moral and psychological processes of an individual’s decision-making and its connection to society in general. Yet, immediately after Smith’s death, economists made a clean cut and invented a totally new discipline: they switched towards a physicalist understanding of (...) human nature. Humans, like atoms, follow a natural law: they are driven by an emotion (defined as a non-emotion, rationality), namely selfishness. Thus economics became a ‘natural’ science. In the 20th century, the second reinterpretation removed all traces of humanity from the study of economics and declared economics to be a formal science like mathematics and logics. The actor in Phase 3 economics is homo economicus syntheticus, a postulate whose only connection to real humanity is the word homo. The paper asks what the results of this dramatic relocation are and why Phase 3 economics still claims descent from Smithian economics, despite the massive differences. (shrink)

Adam Smith’s is often falsely portrayed as having argued that radical selfishness is a force for the good and that this “invisible hand’ is his market mechanism. This paper argues that Smith’s real market mechanism, the sympathy manoeuvre, is a viable alternative to Schumpeterian and mainstream models of innovation in economics and also could help build a firmer theoretical basis for other approaches such as Responsible Innovation. To Smith all human activity was social and must be understood and explained in (...) terms of the sentiments involved. Discovery, for instance, is driven by three sentiments (wonder, surprise, admiration), economic activities by sympathetic imagination, the need for exchange, the need to better one’s position in life, and the need for gratitude. Through sympathetic imagination, his famous model of the impartial spectator, Smith elegantly connects the individual and society. Smith’s innovation process is thus an exercise in social construction and not a destructive process based on radical selfishness. The paper argues that this social innovation process is a viable alternative to the extant approaches that are essentially asocial and amoral (economism) or ideologically normative (Responsible Innovation).

CST is widely disregarded in the academic and public discourse. This essay argues that this is the case for two related reasons. Firstly, CST is based on the pre-Enlightenment approach to moral philosophy, virtue ethics, while the mainstream in business ethics favours the rule-based approaches consequentialism and deontology and their variants. Secondly, mainstream approaches also have adopted a positivist epistemology where theories represent the Truth that must not be questioned: they have become ideologies. This paper argues that CST, mainly through (...) the virtue ethical doctrine of the mean, is saved from having become an ideology and is much closer to the ideal of science as a self-questioning system than the mainstream in business ethics. This essay explains this counter-intuitive conclusion by tracing the history of CST and embedding it in an epistemic discussion and then suggesting what business ethics could take from CST to regain the all-important discursiveness it once had.

The biggest research programme within business ethics is arguably Corporate Social Responsibility and all its related streams (Corporate Citizenship, Social Justice, etc.) While there seems to be widespread agreement that business ethics is situated between the amoral or even immoral view of Milton Friedman as explicated in his 1970 New York Times paper, and the moral view expounded by R. Edward Freeman, this essay challenges that view. Friedman, maybe owed to his flamboyant writing style and crude and purely rhetorical oversimplifications (...) has been misinterpreted to advocate for managers to be completely amoral maximisers of profitability. This misinterpretation has become common wisdom, despite him clearly stating that the law and the moral standards of surrounding society must limit profit-seeking behaviour. Freeman's stakeholder theory, on the other hand, is seen as being on the other end of the continuum, arguing for selflessness—another misinterpretation, as I argue with Ed Freeman's help. Instead, I suggest that both Friedman and Freeman represent the virtuous mean of the business ethics continuum and not its extremes because they both base their theories on the idea of the free and socially embedded individual. The two vicious ends of the continuum are inhabited by the unreal, atomised, completely a-social and selfish individual on the one end, and by the equally unreal collectivised self-less individual on the other. The mainstream in business ethics has declared the collective and selfless end to be the ideal that must guide practice and research. The selfish and the selfless strawmen have prevented a proper debate in business ethics for too long. (shrink)

Corporate/collective moral responsibility is a thorny topic in business ethics and this paper argues that this is due a number of unacknowledged and connected epistemic issues. Firstly, CSR, Corporate Citizenship and many other research streams that are based on the assumption of collective and/or corporate moral responsibility are not compatible with Kantian ethics, consequentialism, or virtue ethics because corporate/collective responsibility violates the axioms and central hypotheses of these research programmes. Secondly, in the absence of a sound theoretical moral philosophical foundation, (...) business ethicists have based their ideas on legal and political epistemologies, yet still claim to be ethics-based. Thirdly, research is often driven by an intention to prove that a specific social goal is right, not by open and critical inquiry. Finally, today, corporate/collective moral responsibility is widely accepted as the Truth as most researchers are unaware of any issues because they are untrained in philosophy. The paper identifies the confusion about the epistemic basis as a major impediment for delivering a thick concept of the role of corporations as moral agents. Thus, the paper does not argue against corporate or collective agency as such, but points out an obvious but forgotten paradox: corporate and collective personhood cannot, at the moment at least, be epistemologically grounded in the field in which business ethics claims to operate: moral philosophy.

Rationality and reason are often used as synonyms, although they are very different concepts. In this article we argue that rationality is the concept of reason that has been stripped of its human elements. Ancient and medieval philosophers such as Aristotle and Aquinas stressed that the concept of reason is composed of sensitive, discursive, and moral elements. Post-Enlightenment thinkers instead, building on the works of René Descartes and Isaac Newton, took these out and claimed that rationality must be based on (...) an external logic devoid of value-concepts such as perfection, harmony, meaning and aim (Koyré in From the closed world to the infinite universe, The Johns Hopkins University Press, Baltimore, 1957). The purpose of this essay is to highlight this shift in Western thought and its consequences for management theories. While explaining the ancient concept of reason in contrast with modern rationalism (Klein in: Williamson RB, Zuckerman E (eds) Jacob Klein—lectures and essays, St. John’s College Press, Annapolis, 1985), we aim at raising awareness of the differences between building a research programme (especially in business sciences like economics and management) on rationality or on reason.

In quantum logics, the notions of strong and full order determination and unitality for states on orthomodular posets are well known. These notions are defined for hypergraphs and their state spaces in a consistent manner and the relations between them and to the notions defined for orthomodular posets are discussed. The state space of a hypergraph is a polytope. This polytope is a simplex if and only if every superposition of pure states is a mixture of these same pure states. (...) Isomorphic hypergraphs have convexly isomorphic state spaces. A class of hypergraphs is given whose group of automorphisms is group-isomorphic to the group of convex automorphisms of their state spaces. (shrink)

Business Ethics: A European Review, EarlyView.

We propose an alternative resolution of Simpson's paradox in multiple classification experiments, using a different maximum likelihood estimator. In the center of our analysis is a formal representation of free choice and randomization that is based on the notion of incompatible measurements.We first introduce a representation of incompatible measurements as a collection of sets of outcomes. This leads to a natural generalization of Kolmogoroff's axioms of probability. We then discuss the existence and uniqueness of the maximum likelihood estimator for a (...) probability weight on such a generalized sample space, given absolute frequency data.As a first example, we discuss an estimation problem with censured data that classically admits only biased ad hoc estimators.Next, we derive an explicit solution of the maximum likelihood estimation problem for a large class of experiments that arise from various kids of compositions of sample spaces. We identify the (categorical) direct sum of sample spaces as a representation of “free choice,” and the (categorical) direct product as a representation of “randomization.”Finally, we apply the foregoing discussion to the case of multiple classification experiments in order to show that there is no Simpson's paradox if the difference between free choice and randomization is recognized in the structure of the experiment.A comparison between our new estimator and the “usual” calculation can be summarized as follows: Pooling the data over one classification factor in the “usual” way in fact destroys or ignores the information contained in it, whereas our proposed maximum likelihood estimator is a proper marginal over this factor that “averages out” the information contained in it. The estimators agree with each other in the case of proportional sample sizes. (shrink)

The paper expands on Goshal’s criticism of what management as a scientific discipline teaches and the effects on managerial and societal ethics. The main argument put forward is that the economisation of management has a detrimental effect on the practice of management and on society in large. The ideology of economism is described and analysed from an epistemological perspective. The paper argues that the economisation of management not only introduces the problems of economics (three are identified and discussed) but destroys (...) the very essence of management because economics is focused on efficiency and management should be focused on effectiveness. What is more, the basic axioms of mainstream economics stand in stark contrast to the philosophy of the Enlightenment and therefore endanger the foundations of Western societies. Management theory (via corporate governance) is the Trojan horse carrying economism into society. (shrink)

Psychologists and moral philosophers have much to say about self-awareness and so it is no surprise that in leadership research self-awareness also has come to play an important role. For some time now, leadership research has been dominated by psychologists and we argue that their version of the self-awareness is very thin. It is empty of morality and therefore offers only a partial understanding of humanity. That make its conclusions for leadership ineffective and unethical. Psychology-driven approaches to leadership stress effectiveness: (...) leaders make followers work towards a given goal in an effective manner. Self-awareness, to them, is a thorough understanding of one’s strengths, weaknesses, values, how others see one, all with the goal of turning people into followers. Since ethics is excluded, this view of self-awareness lacks a foundational moral concept: respect/dignity and is closer to self-assessment. Building on Immanuel Kant and other German Idealists, Georg Friedrich Wilhelm Hegel proposed a theory of the development of self-awareness that is more holistic as it situates the individual in a social and moral context and thus transcends the purely functional view of the self-other relationship propagated in psychological approaches. We concretely argue that psychological approaches to leadership systematically drive managers into a catastrophic situation that Hegel describes in the Master-Slave Dialectic. Understanding Hegelian self-awareness prevents leaders becoming self-less masters. Truly self-aware leaders heed the warning of the Humanity Formulation of Kant’s Categorial Imperative, namely that they must always treat humanity, whether in their own person or in the person of any other, never merely as a means to an end, but always at the same time as an end. They understand their self, they understand its social and moral dimension, and they see their self-reflected in the other. (shrink)

We identify a normative paradox of responsible management education. Business educators aim to promote social values and develop ethical habits and socially responsible mindsets through education, but they attempt to do so with theories that have normative underpinnings and create actual normative effects that counteract their intentions. We identify a limited conceptualization of freedom in economic theorizing as a cause of the paradox. Economic theory emphasizes individual freedom and understands this as the freedom to choose from available options. However, conceptualizing (...) individuals as profit-maximizing actors neglects their freedom to reflect on the purposes and goals of their actions. We build on the work of pragmatist philosopher John Dewey, who distinguishes between habitualized and creative problem-solving behaviors, conceptualizes knowledge construction as a process of interdependent scientific social inquiry, and understands actors as having the freedom to determine what kind of people they wish to be. We apply pragmatist theory to business education and suggest equipping students with a plurality of theories, supplementing neoclassical economics with other economic perspectives and views from other disciplines on economic behavior. Moreover, we suggest putting students into learning situations that require practical problem solution through interdependent social inquiry, encouraging ethical reflection. In doing so, we contribute by linking the problematic conceptions of freedom identified in economic theorizing to the debate on responsible management education. We conceptualize a pragmatist approach to management education that explicitly re-integrates the freedom to discursively reflect on the individual and societal purpose of business activity and thereby makes existing tools and pedagogies useful for bringing potential freedom back into business.

:In a recent paper in Cambridge Quarterly of Healthcare Ethics on the necessary conditions for morally responsible animal research David DeGrazia and Jeff Sebo claim that the key requirements for morally responsible animal research are an assertion of sufficient net benefit, a worthwhile-life condition, and a no-unnecessary-harm condition. With regards to the assertion of sufficient net benefit, the authors claim that morally responsible research offers unique benefits to humans that outweigh the costs and harms to humans and animals. In this (...) commentary we will raise epistemic, practical, and ethical challenges to DeGrazia and Sebo’s emphasis on benefits in the prospective assessment of research studies involving animals. We do not disagree with DeGrazia and Sebo that, at the theoretical level, the benefits of research justify our using animals. Our contribution intends to clarify, at the practical level, how we should understand benefits in the prospective assessment and moral justification of animal research. We argue that ASNB should be understood as an assessment of Expectation of Knowledge Production in the prospective assessment and justification of animal research. EKP breaks down into two further claims: that morally responsible research generates knowledge worth having and that morally responsible research is designed and executed to produce generalizable knowledge. We understand the condition called knowledge worth having as scientists’ testing a hypothesis that, whether verified or falsified, advances an important interest, and production of generalizable knowledge in terms of scientific integrity. Generalizable knowledge refers to experimental results that generalize to a larger population beyond the animals studied. Generalizable scientific knowledge is reliable, replicable, and accurately descriptive. In sum, morally responsible research will be designed and carefully executed to successfully test a hypothesis that, whether verified or falsified, advances important interests. Our formulation of EKP, crucially, does not require further showing that an experiment involving animals will produce societal benefits. (shrink)

This paper contributes to the (re-)conceptualisation of responsible innovation by proposing an evolutionary economic approach that focuses on the role of consumers in the innovation process. After a discussion of the philosophical foundations and ethical implications of this approach, which bears an explanatory potential that has not been adequately considered in previous discussions of responsible innovation, we present a first step towards capturing the important but often neglected role of consumers in innovation processes (including responsible innovation): We propose an agent-based (...) model that incorporates a multidimensional space of characteristics in which new products or services are represented by more than the mere aspect of price and quality. Instead, innovations are denoted by a large set of characteristics, including also negative or harmful ones. The model is used to illustrate that consumers’ heterogeneity and bounded rationality – even if considered in a simple manner – indeed play a crucial role in the creation and diffusion of responsible innovation which can and should be used for further work in this field and for possible extensions of the model.

Successful transitions to a sustainable bioeconomy require novel technologies, processes, and practices as well as a general agreement about the overarching normative direction of innovation. Both requirements necessarily involve collective action by those individuals who purchase, use, and co-produce novelties: the consumers. Based on theoretical considerations borrowed from evolutionary innovation economics and consumer social responsibility, we explore to what extent consumers’ scope of action is addressed in the scientific bioeconomy literature. We do so by systematically reviewing bioeconomy-related publications according to (...) the extent to which consumers are regarded as passive vs. active, and different domains of consumer responsibility. We find all aspects of active consumption considered to varying degrees but observe little interconnection between domains. In sum, our paper contributes to the bioeconomy literature by developing a novel coding scheme that allows us to pinpoint different aspects of consumer activity, which have been considered in a rather isolated and undifferentiated manner. Combined with our theoretical considerations, the results of our review reveal a central research gap which should be taken up in future empirical and conceptual bioeconomy research. The system-spanning nature of a sustainable bioeconomy demands an equally holistic exploration of the consumers’ prospective and shared responsibility for contributing to its coming of age, ranging from the procurement of information on bio-based products and services to their disposal.

The spiders Cupiennius salei and Achaearanea tepidariorum are firmly established laboratory models that have already contributed greatly to answering evolutionary developmental questions. Here we appraise why these animals are such useful models from phylogeny, natural history and embryogenesis to the tools available for their manipulation. We then review recent studies of axis formation, segmentation, appendage development and neurogenesis in these spiders and how this has contributed to understanding the evolution of these processes. Furthermore, we discuss the potential of comparisons of (...) silk production between Cupiennius and Achaearanea to investigate the origins and diversification of this evolutionary innovation. We suggest that further comparisons between these two spiders and other chelicerates will prove useful for understanding the evolution of development in metazoans.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

According to William Alston, we lack voluntary control over our propositional attitudes because we cannot believe intentionally, and we cannot believe intentionally because our will is not causally connected to belief formation. Against Alston, I argue that we can believe intentionally because our will is causally connected to belief formation. My defense of this claim is based on examples in which agents have reasons for and against believing p, deliberate on what attitude to take towards p, and subsequently acquire an (...) attitude A towards p because they have decided to take attitude A. From the possibility of intentional belief, two conclusions follow. First, the kind of control we have over our propositional attitudes is direct; it is possible for us to believe at will. Second, the question of whether what we believe is under our control ultimately depends on whether our will itself is under our control. It is, therefore, a question of the metaphysics of free will.

It was, until recently, accepted that the two classes of acetylcholine (ACh) receptors are distinct in an important sense: muscarinic ACh receptors signal via heterotrimeric GTP binding proteins (G proteins), whereas nicotinic ACh receptors (nAChRs) open to allow flux of Na+, Ca2+, and K+ ions into the cell after activation. Here we present evidence of direct coupling between G proteins and nAChRs in neurons. Based on proteomic, biophysical, and functional evidence, we hypothesize that binding to G proteins modulates the activity (...) and signaling of nAChRs in cells. It is important to note that while this hypothesis is new for the nAChR, it is consistent with known interactions between G proteins and structurally related ligand‐gated ion channels. Therefore, it underscores an evolutionarily conserved metabotropic mechanism of G protein signaling via nAChR channels.Also watch the Video Abstract. (shrink)

P. Churchland argued for the nomological character of action explanation by presenting an alleged law - I call it below L2 - which, according to Churchland, we make use ofimplicitly when explaining rational actions.

According to this alternative interpretation, L2 is not a law, but, it indicates the general form of complete action explanations. I shall argue that this alternative interpretation is (...) more acceptable than Churchland 's interpretation of L2 as a law. Moreover, if the alleged law is interpreted as the general form of action explanations, then Churchland 's article even transforms itself into a confirmation ofthe non-nomological character of action explanation.

In this paper, we trace the conceptual history of the term ?metamathematics? in the nineteenth century. It is well known that Hilbert introduced the term for his proof-theoretic enterprise in about 1922. But he was verifiably inspired by an earlier usage of the phrase in the 1870s. After outlining Hilbert's understanding of the term, we will explore the lines of inducement and elucidate the different meanings of ?metamathematics? in the final decades of the nineteenth century. Finally, we will investigate the (...) earlier occurrences and come to the conclusion that the conceptual prehistory of the Hilbertian notion of metamathematics dates back to 1870, whereas the history of the word starts in 1799 at the latest.

The length of resolution proofs is investigated, relative to the model-theoretic measure of Herband complexity. A concept of resolution deduction is introduced which is somewhat more general than the classical concepts. It is shown that proof complexity is exponential in terms of Herband complexity and that this bound is tight. The concept of R-deduction is extended to FR-deduction, where, besides resolution, a function introduction rule is allowed. As an example, consider the clause P Q: conclude P) Q, where a, f (...) are new function symbols extending Herbrand's universe. P ()Q from Q) and Skolemization).

The generalization properties of algebraically closed fields $ACF_p$ of characteristic $p > 0$ and $ACF_0$ of characteristic 0 are investigated in the sequent calculus with blocks of quantifiers. It is shown that $ACF_p$ admits finite term bases, and $ACF_0$ admits term bases with primality constraints. From these results the analogs of Kreisel's Conjecture for these theories follow: If for some $k$ , $A(1 + \cdots + 1)$ ( $n$ 1's) is provable in $k$ steps, then $(\forall x)A(x)$ is provable.

Die Philosophie des Neuplatonismus zwischen Porphyrios, Jamblich und Syrian ist uns nur sehr lückenhaft bekannt. Schließen können wir diese Lücke nur mit Hilfe von Autoren wie des römischen Rhetors Marius Victorinus, der sich nach seiner Konversion zum Christentum daranmachte, mit Hilfe der von ihm vorher in Rom gelehrten Philosophie die christliche Trinitätslehre zu verteidigen. Wir wir seit den bahnbrechenden Arbeiten von P. Hadot über Marius Victorinus wissen, hat sich Victorinus dabei einer Form des Neuplatonismus bedient, die nachplotinisch ist. Aber während (...) P. Hadot diese Lehre als die des Plotinschülers Porphyrios nachzuweisen versucht, kommt die vorliegende Studie zu dem Ergebnis, dass sie nach Porphyrios und wahrscheinlich auch nach Jamblich anzusetzen ist.

Gottlob Frege’s Grundgesetze der Arithmetik (Basic Laws of Arithmetic, Vol. I/II; 1893/1903) is a modern classic. Since the 1930s it has belonged to an exclusive class of only eleven works in the history of symbolic logic, which contain the ‘first appearance of a new idea of fundamental importance’ [Church, 1936, p. 122], and its author is the only one whose other major works — Begriffsschrift (1879) and Die Grundlagen der Arithmetik (1884) — also belong to this distinguished group. Together with (...) the seminal paper ‘Über Sinn und Bedeutung’ these three monographs represent the essential contributions to one of the most fascinating foundational projects in mathematics, then and now. For decades Frege struggled with the question, ‘how are we to apprehend logical objects, in particular, the numbers? What justifies us in acknowledging numbers as objects?’ [Frege, 2013, ‘Afterword’, p. 265]. His favourite answer, for a long time, was that arithmetic is a complex branch of logic. But since there is no logicism without logic, Frege started in Begriffsschrift with the invention of a nearly perfect formalization of higher-order classical predicate logic. To discover how far we can get in arithmetic by analytic means alone, it was even necessary to clarify the semantic character of the concept of number. This was done in a marvellous way by Frege five years later, in Grundlagen. The next step was nothing less than the complete execution of his logicist project, a monumental undertaking; and it is well known that here Frege failed, due to Russell’s derivation of the antinomy in 1902. But, despite the contradiction, Grundgesetze contains Frege’s legacy to logicism, which became more and more attractive. (shrink)

Two claims are essential to foundationalist theories of knowledge. First, that there are directly evident propositions; secondly, that, in justifying a particular knowledge claim, one ultimately arrives at a directly evident proposition making another proposition evident. In this dissertation, both claims are being defended. ;In defense of the first claim, a week definition of a proposition's being directly evident is suggested. Any attack against foundationalism rejecting the first claim must show that there are no contingent directly evident propositions in the (...) sense of this definition. According to the thesis of privileged access, what a man believes about his mental states is directly evident, or, according to different versions of this thesis, self-presenting, infallible, self-evident, indubitable, or incorrigible. Rejecting a number of objections to it, the thesis of privileged access in all of its versions is being defended. In defense of the second claim, an account of prima facie evidence is set forth, incorporating definitions of the concepts "e tends to make h evident," "i defeats the evidence e provides for h," and "e makes h prima facie evident for S." It is claimed that, if a proposition p is made prima facie evident for a person S, then there is no ground on which it is reasonable for S to doubt that p is true. ;Furthermore, two epistemic principles are being offered. The first lays down the conditions under which evidence is generated, asserting that evidence is generated in virtue of a person's being in a psychological state. The second lays down the conditions under which evidence is transmitted from a directly to an indirectly evident proposition, asserting that evidence is transmitted from a directly to an indirectly evident proposition if the former bears to the latter the relation of "e making h prima facie evident.".

In lieu of an abstract, here is a brief excerpt of the content:From Dilthey to Mead and Heidegger: Systematic and Historical Relations MATTHIASJUNG FOR TODAY'S READER, G. H. Mead's lectures on Movements of Thought in the Nineteenth Century offer a surprise: Mead, despite having attended his lectures from 1889 to 1891, does not mention the name of Wilhelm Dilthey, who nowadays is regarded as one of the classical authors of nineteenth-century philosophy. Mead's lectures lack any sign of awareness concerning the (...) hermeneutic tradition, represented by such names as Friedrich Schlegel, Schleiermacher, Droysen and, of course, Dilthey. Nevertheless it is, as I would like to show in the following pages, quite obvious that Mead's own philosophical conception shows some striking parallels with Dilthey's thought, which can be explained partly through direct influence, partly through the similarity of the questions both tried to answer. For Mead's missing reference to the mentioned tradition, I see two complementary explanations. Firstly, the philosophical importance of the hermeneutic tradition in nineteenth-century philosophy was mainly a retrospective matter. Only after 1927, when Martin Heidegger published Being and Time, did philosophical interest in hermeneutics begin; and then it took thirty-three years more till Hans-Georg Gadamer's Truth and Method brought about a historical interest in the development of hermeneutic thought. Secondly, Mead's own passion for the development of science may have forced him to neglect these philosophical movements, which seemed to resist the autocracy of (natural) science. Wilhelm Dilthey's thought, especially around the year 189o, can systematically be interpreted as a common starting-point for two of the most important directions of contemporary philosophy: pragmatism and hermeneutics. It is but a small exaggeration to say that G. H. Mead drew out the pragmatic, Martin Heidegger the hermeneutic consequences of Dilthey's concept of [661 ] 662 JOURNAL OF THE HISTORY OF PHILOSOPHY 33:4 OCTOBER ~995 Seelenleben, understood as a "best~indige Wechselwirkung zwischen unserem Eigenleben und dem Milieu. ''1 Mead's phase-model of acting, his whole idea of understanding meaning as the result of a social process, are paralleled and partly anticipated by Dilthey, as is Heidegger's conception of Dasein as "beingin -the-world" and his attempt to understand the inner historicity of life.2 In pointing this out, I do not want to claim that Mead was conscious of the systematic relation of his theories to Dilthey's work; nevertheless I will argue that Dilthey's ideas may have served as a source of inspiration and, furthermore, that this inspiration was made possible through some important similarities in the systematic architecture of both hermeneutics and pragmatism.3 I begin by working out the historical dimension, which Hans Joas characterized as "Meads biographische Abkunft von Dilthey"4 (section l). After that, I will sketch Dilthey's philosophical position around 189o in order to show how he works to transform the German tradition of "philosophy of consciousness" into a new concept of interaction between the life-processes of detranscendentalized subjects and their environment (section 2). Having done this, I will be ready to discuss the parallels between Mead's pragmatic approach to the life-process and Dilthey's work (section 3). Finally, the early Heidegger's and Mead's transformations of "philosophy of consciousness" will briefly be interpreted as different ways of overcoming the inherent problems of Dilthey 's attempt (section 4). Between April 23, 1889 and October ~4, 1891 G. H. Mead was registered at the Humboldt-University of Berlin.5 During this period Wilhelm Dilthey, who had come from Breslau to Berlin in 1882, gave the following lectures: "Geschichte der neueren Philosophie"; "Geschichte und System der P/idagogik "; "Logik und Erkenntnistheorie"; "Psychologie als Erfahrungswissen- ' Wilhelm Dilthey, DichterischeEinbildungskraft und Wahnsinn, in GesammelteSchriften, Bd. VI (Stuttgart/G6ttingen: Teubner/Vandenhoeck &Ruprecht, 1962),95. 9In Sein und Zeit (cited from the 15th edition, Tfibingen: Niemeyer, 1979),Heidegger refers frequently to Dilthey: 46, 47, 2o5, 2~ 249, 376f-, 385, 397-4o4 9The two most important sources concerning his early reception of Dilthey'swork are the lecture from the summer semester of 192o,Phi~nomenologieder Anschauung und des Ausdrucks, ed. C. Strube (Frankfurt: Klostermann, 1993) and the "Kasseler Vortr~ge," given in 1925 under the title "Wilhelm Diltheys Forschungsarbeit und der... (shrink)

Of late, evidentiality has received great attention in formal semantics. In this paper I develop ‘evidentiality-informed’ truth conditions for modal operators such as must and may . With language data drawn from Luoping Nase (a Tibeto-Burman language spoken in the P.R. of China and belonging to the Yi Nationality), I illustrate that epistemic modals clash with clauses articulating first-hand information. I then demonstrate that existing models such as Kratzer’s graded possible-worlds semantics fail to provide accurate truth conditions for modals tagging (...) clauses with first-hand information. As a remedy I propose a fuzzy version of possible-worlds semantics with various grades of belief and knowledge. In addition to preserving the expressive power of graded possible-worlds semantics, the fuzzy model will be shown to supply appropriate truth conditions for epistemic modals appended to evidential clauses (i.e. clauses expressing first-hand information).

In this rejoinder, we respond to two commentaries on the study by Greiff, S.; Stadler, M.; Sonnleitner, P.; Wolff, C.; Martin, R. Sometimes less is more: Comparing the validity of complex problem solving measures. Intelligence 2015, 50, 100–113. The study was the first to address the important comparison between a classical measure of complex problem solving (CPS) and the more recent multiple complex systems (MCS) approach regarding their validity. In the study, we investigated the relations between one classical microworld as (...) the initially developed method (here, the Tailorshop) with three more recently developed multiple complex systems (MCS; here, MicroDYN, Genetics Lab, and MicroFIN) tests. We found that the MCS tests showed higher levels of convergent validity with each other than with the Tailorshop even after reasoning was controlled for, thus empirically distinguishing between the two approaches. The commentary by Kretzschmar and the commentary by Funke, Fischer, and Holt expressed several concerns with how our study was conducted, our data was analyzed, and our results were interpreted. Whereas we acknowledge and agree with some of the more general statements made in these commentaries, we respectfully disagree with others, or we consider them to be at least partially in contrast with the existing literature and the currently available empirical evidence.
