We present an investigation into the relation between design princi- ples in Japanese gardens, and their associated perceptual effects. This leads to the realization that a set of design principles described in a Japanese gardening text by Shingen (1466), shows many parallels to the visual effects of perceptual grouping, studied by the Gestalt school of psychology. Guidelines for composition of rock clusters closely relate to perception of visual figure. Garden design elements are arranged into patterns that simplify figure-ground segmentation, while (...) seemingly balancing the visual salience of subparts and the global arrangement. Visual ‘ground’ is analyzed via medial axis transformation (MAT), often associated with shape perception in humans. MAT analysis reveals implicit structure in the visual ground of a quintessential rock garden design. The MAT structure enables formal com- parison of structure of figure and ground. They share some aesthetic qualities, with interesting differences. Both contain naturalistic asymmetric, self-similar, branching structures. While the branching pattern of the ground converges towards the viewer, that of the figure converges in the opposite direction. (shrink)

In the realm of the humanities, Paul Ricoeur (1913–2005) is widely viewed as one of the most influential philosophers of the twentieth century. He published an impressive and comprehensive oeuvre that made an impact on almost all areas of the humanities. By combining the resources and insights of phenomenology and hermeneutics, he developed new perspectives on the text, on metaphor, on narrative, and on personal identity that pervaded theology, history, linguistics, psychoanalysis, ethics,(philosophical) anthropology, cognitive sciences, and so on. In light (...) of his centennial in 2013, the question arises whether his theories have a future and can be extended to capture new phenomena studied in the humanities: What is the impact and meaning of the oeuvre of Paul Ricoeur for the humanities? In particular, one may develop this question as follows: Which of Ricoeur’s major contributions can be expected to remain relevant for the humanities? In what way can we relate Ricoeur’s oeuvre to ideas and methods of other philosophers and scientists? Does Ricoeur’s paradigm of the text still provide a relevant framework for thinking about the basic questions that concern the humanities today? If so, how can we bring Ricoeur’s perspective in a fruitful tension or dialogue with other, competing paradigms? (shrink)

The philosophical point of view of Richard Heinrich Ludwig Avenarius (Habermann) (19.11.1843-18.08.1896) is still little mastered and represented in philosophical thought in modern Russia. However, at the turn of the 19th and 20th centuries, it inspired many minds of that period. The views of Avenarius were studied by Lesevich V.V., Tronin V.V., Gurevich A.V., Chelpanov G.I., Filippov M.M., Viktorov D.V. and others. Due to historical circumstances, the time for an unbiased understanding of the concept of Richard Avenarius (...) has stopped for a century. Until now, the publications of Russian translations of his works exist only in pre-reform spelling. Now it is possible to go forward again to Avenarius, so it is relevant to consider how his philosophical discoveries originally appeared and spread in Russia. (shrink)

In the act of knowing consciousness, the experience (experience) of a thing by another individual is put into it. All the components of the environment that manifest themselves in movement, sound, light, resistance, etc. become a source of introjection in the experience. As a result of animism, what exists outside of man is divided into an external world and an extra-world existence, and knowledge is differentiated into sensuous and non-empirical. The original naive empirical duality becomes a metaphysical dualism.

Investigo la relación filosófica entre Avenarius y Husserl en los años del curso Problemas fundamentales de la fenomenología en relación especial con el concepto natural de mundo. Primero, expongo brevemente los temas fenomenológicos fundamentales: el concepto natural de mundo, la reducción fenomenológica y la unidad del yo. En segundo lugar, sintetizo las ideas básicas de la obra Der menschliche Weltbegriff de Avenarius. En tercer lugar, discuto la coincidencia entre Avenarius y Husserl, poniendo énfasis en la reducción primordial, (...) y planteo las críticas de Husserl a Avenarius, destacando la postura unívoca de Avenarius en contraste con la postura fenomenológica de Husserl. I study the philosophical relationship between Avenarius and Husserl during the years where the later held the lectures The Basic Problems of Phenomenology, taking especially into account the natural concept of the world. First, I expound briefly the basic phenomenological topics of the lectures: the natural concept of the world, the phenomenological reduction and the ego's unity. Second, I tackle the basic ideas of Avenarius' Der menschliche Weltbegriff . Third, I discuss the coincidence between Avenarius and Husserl, paying special attention to the primordial reduction, and also the objections that Husserl made to Avenarius, making a contrast between Avenarius' univocal approach to being and Husserl's phenomenological account.

Good book. See this review's final paragraph for my conspiracy theory defending reflectance physicalism.

This critical notice explores the distinction between the justifying and requiring forces of reasons, which Joshua Gert introduced and defended in his book Brute Rationality.

For a symposium on Douglas W. Portmore's Commonsense Consequentialism: Wherein Morality Meets Rationality.

This essay examines the possibility that phenomenological laws might be implemented by a computational mechanism by carefully analyzing key passages from the Prolegomena to Pure Logic. Part I examines the famous Denkmaschine passage as evidence for the view that intuitions of evidence are causally produced by computational means. Part II connects the less famous criticism of Avenarius & Mach on thought-economy with Husserl's 1891 essay 'On the Logic of Signs (Semiotic).' Husserl is shown to reaffirm his earlier opposition to (...) associationist (Humean) and adaptationist (Darwinian) explanations of our thought-machine on the ground that they cannot reconstruct the notion of truth and its syntactic mental preservation in symbolic thought-trains. Part III reveals Husserl's interesting commitment to the idea that descriptive sciences necessarily transform into explanatory sciences on pain of contradicting the essence of science as a rational ideal. Since explanation in relation to phenomenology means causal explanation, and causal explanation in the form of the Denkmaschine accounts for phenomenological intuition, it is inferred that the rationally compelling ideal of explanatory science requires a computationalist reading of the subsequent logical investigations.

In recent years, several philosophers - including Joshua Gert, Douglas Portmore, and Elizabeth Harman - have argued that there is a sense in which morality itself does not treat moral reasons as consistently overriding.2 My aim in the present essay is to develop and extend this idea from a somewhat different perspective. In doing so, I offer an alternative way of formalizing the idea that morality is modest about the weight of moral reasons in this way, thereby making more (...) explicit the connections between this thesis and similar issues in the epistemic sphere. In addition, I discuss how these ideas can transform our thinking about familiar questions in ethics such as the nature of self-effacement, the significance of reflective endorsement, the weight that moral reasons ought to be given in all things consideration, and the plausibility of “indirect” moral theories. Finally, I show that these ideas are compatible even with pictures of morality – such as Kant’s – on which morality might seem to anything but modest about its own importance. In doing so, I stress that it is possible to see morality as modest about the weight of specifically moral reasons, while also seeing all practical reasons as grounded in morality more indirectly – namely, by seeing morality as determining the weight that both moral and non-moral considerations deserve to have in all things considered deliberation.

Reasons-based accounts of our normative conclusions face difficulties in distinguishing between what ought to be done and what is required. This article addresses this problem from a formal perspective. I introduce a rudimentary formalization of a reasons-based account and demonstrate that that the model faces difficulties in accounting for the distinction between oughts and requirements. I briefly critique attempts to distinguish between oughts and requirements by appealing to a difference in strength or weight of reasons. I then present a formalized (...) reasons-based account of permissions, oughts and requirements. The model exploits Joshua Gert (2004; 2007) and Patricia Greenspan’s (2005; 2007; 2010) suggestion that some reasons perform a purely justificatory function. I show that the model preserves the standard entailment relationships between requirements, oughts and permissions. (shrink)

En este artículo queremos investigar la relación entre las filosofías de Edmund Husserl y Richard Avenarius. A pesar de que este tema ha sido prácticamente ignorado por los estudiosos de Husserl, es de suma importancia si uno quiere iluminar los orígenes del pensamiento fenomenológico de Husserl. Nuestra tesis es que el concepto de Husserl de actitud natural y su correlato, el mundo natural -tal y como ellos surgen en diferentes conferencias durante la década de 1910 y especialmente en Ideas (...) I con respecto a la reducción fenomenológica- se derivan de una temprana confrontación con el punto de vista del empiriocriticismo de Avenarius como fue expuesto en su libro Der menschliche Weltbegriff. Con el fin de mantener esta afirmación, discutiremos el acercamiento gradual de Husserl a las teorías del filósofo suizo-alemán así como su última crítica al mismo. Aunque, de hecho, Husserl concibió el punto de vista den Avenarius como un principio valioso, al final de sus reflexiones pone en cuestión algunas de las premisas de la filosofía empiriocriticista.

Introduction to volume containing essays by Simon Blackburn, John Cottingham, Frances Ferguson, Joshua Gert, Peter Goldie, Charles Guignon, Sharon Krause, Christopher Kutz, Daniel Markovits, Elijah Millgram, Martha Nussbaum, and Carol Rovane.

We can often permissibly choose a worse self-interested option over a better altruistic alternative. For example, it is permissible to eat out rather than donate the money to feed five hungry children for a single meal. If we eat out, we do something permissibly partial toward ourselves. If we donate, we go beyond the call of moral duty and do something supererogatory. Such phenomena aren’t easy to explain, and they rule out otherwise promising moral theories. Incommensurability and Ruth Chang’s notion (...) of parity can explain certain small improvement puzzles, but they can’t explain permissible partiality and supererogation. On the other hand, Josh Gert’s distinction between justifying and requiring weight can explain all three phenomena: permissible partiality, supererogation, and the relevant small improvement puzzle. Indeed, this chapter provides a reason to endorse the justifying/requiring weight distinction by showing that it provides the only extant explanation of all three phenomena. (shrink)

Johnston famously argued that the colors are, more or less inclusively speaking, dispositions to cause color experiences by arguing that this view best accommodates his five proposed core beliefs about color. Since then, Campbell, Kalderon, Gert, Benbaji, and others, have all engaged with at least some of Johnston’s proposed core beliefs in one way or another. Which propositions are core beliefs is ultimately an empirical matter. We investigate whether Johnston’s proposed core beliefs are, in fact, believed by assessing the (...) agreement/disagreement of non-philosophers with them. Two experiments are run each with large sample sizes, the second designed to address criticisms of the first. We find that non-philosophers mostly agree with the proposed core beliefs, but that they agree with some more than others. (shrink)

This paper analyses three centuries of developing German-language philosophy journals, from the first journals published in 1665 to those from the first decade of post-WWII recovery. Relying upon two bibliographies of philosophical journals collected in the 1970s, one by Joachim Kirchner and one by Wolfram Hogrebe, Rudolf Kamp, and Gert König, we attained a dataset of 607 journals. To analyse the population of periodicals, we identified three key components: the longevity of each journal and the growth rate and the (...) continuity of the body of the journal population. The most puzzling finding is that there was a rapid growth in the number of journals at the end of the eighteenth century followed by a long decline in numbers that lasted almost a century. This paper analyses the structure of the boom in philosophical periodicals after 1888, followed by the effects of both World Wars, and identifies the communication crisis that occurred at the height of the Weimar Republic.

Can Marxist-Leninist philosophy disregard dialectical materialism, the analysis of material and social contradictions, the need to overcome and resolve them in the service of revolutionary transformation? ‘Does the lecturer acknowledge that the philosophy of Marxism is dialectical materialism’, as Lenin asked Bogdanov one day in May 1908? What had 'official Soviet Marxism' really become, capable of combining ideological dictatorship with militant philosophical ignorance, in turn justified by the achievements of modern science, skilfully used as an instrument of domination and preservation (...) of the established order? How can one conceptually dominate reality and its contradictions, knowing well that knowledge is never neutral but is class-based? These questions are answered by Evald Ilyenkov, one of the greatest Marxist philosophers of the 20th century, re-examining Lenin's Materialism and Empiriocriticism at the end of the 1970s with a text entitled Leninist Dialectics and the Metaphysics of Positivism, still unpublished in Italy, and identifying in the revolutionary leader an exceptional theoretical ally. Just as Lenin had had to fight the attacks promoted by the theories of Bogdanov, who approached the empirio-criticism of Mach, Avenarius and Berman, seeing it as dogmatic and reactionary materialism directed against the natural sciences, so Ilyenkov fought against the penetration of positivism into Soviet politics and philosophy, criticizing the rejection of the dialectic only functional to the technocratic project of building 'socialism' in the Brezhnev era, a disguised heir of the empirio-criticism denounced by Lenin as the natural metaphysical conclusion to the logic of positivism.

This article examines the meaningful intervention that Gert-Jan Van der Heiden’s recent book, The Voice of Misery: A Continental Philosophy of Testimony, makes in the developing field of the philosophy of testimony. I argue that this intervention is accomplished through a phenomenological investigation into the nature of the testimonial object and of the demand that it makes upon one who bears witness. In taking such an approach, I argue, Van der Heiden initiates an ontological turn in the field of (...) testimonial theory, shifting the conversation away from a debate about the conditions in which belief in testimony is justified – a debate that has in many ways defined the field for philosophers in the Anglo-American tradition. I suggest that Van der Heiden’s account is helpful in demonstrating that, in many cases, doing justice to a testimonial object requires an epistemic-ethical attitude other than belief. The article concludes by developing a few questions for Van der Heiden based on my interpretation of his project, including to what extent his phenomenology of testimony can account for how often our receptivity to testimony depends on the default trust that we have in others by virtue of our fundamental immersion in social life.

This paper begins with a response to Josh Gert’s challenge that ‘on a par with’ is not a sui generis fourth value relation beyond ‘better than’, ‘worse than’, and ‘equally good’. It then explores two further questions: can parity be modeled by an interval representation of value? And what should one rationally do when faced with items on a par? I argue that an interval representation of value is incompatible with the possibility that items are on a par (a (...) mathematical proof is given in the appendix). I also suggest that there are three senses of ‘rationally permissible’ which, once distinguished, show that parity does distinctive practical work that cannot be done by the usual trichotomy of relations or by incomparability. In this way, we have an additional argument for parity from the workings of practical reason. (shrink)

On a ‘comparative’ conception of practical reasons, reasons are like ‘weights’ that can make an action more or less rational. Bernard Gert adopts instead a ‘toggle’ conception of practical reasons: something counts as a reason just in case it alone can make some or other otherwise irrational action rational. I suggest that Gert’s conception suffers from various defects, and that his motivation for adopting this conception – his central claim that actions can be rational without there being reasons (...) for them – does not require adoption of the toggle conception. The more intuitive comparative conception of reasons for action can accommodate the insight. (shrink)

In this paper I reply to two sets of criticisms—a first from Joshua Gert, and a second from Keith Allen—of the relationalist view of color developed and defended in my book, The Red and the Real: An Essay on Color Ontology.

Diese Arbeit zeichnet die Schwierigkeit nach, die Franz Brentano zwischen der Begruendung der Sittlichkeit aus moralischem Gefuehl und der Begruendung aus Vernunftgruenden zeitlebens gehabt hat: Die Eroerterung eines Gefuehls verwandelt dieses unweigerlich in ein Konzept der Kommunikation, das nicht nur rationaler, vielmehr noch oeffentlicher Diskussion zugaenglich wird. Beschraenkt man aber die Quelle des moralischen Gefuehls UND den Verstand auf ein individuelles Subjekt, geraet man mit der Untersuchung der Evidenz der sittlichen Erkenntnis in die naemlichen Aporien wie Franz Brentano.
