Hume appeals to a mysterious mental process to explain how to world appears to possess features that are not present in sense perceptions, namely causal, moral, and aesthetic properties. He famously writes that the mind spreads itself onto the external world, and that we stain or gild natural objects with our sentiments. Projectivism is founded on these texts but it assumes a reading of Hume’s language as merely metaphorical. This assumption, however, conflicts sharply with the important explanatory role that “spreading” (...) and “staining” are supposed to play, which, ironically, is the very appeal of Hume’s texts to projectivists. In this paper, I first consider the difficulties readers of Hume have encountered in their attempts to ascertain nature of the key psychological process. I then identify in Hume’s texts novel theoretical resources that allow Hume to produce a satisfying answer to the question of process, that is, an account of the precise nature of the key process. I offer this explanation assuming what I take to be Hume’s austere conception of the elements involved in the process: sense impressions and “internal impressions” lacking intrinsic intentionality. On my reading, the spreading process explains the gap between the meager input and the rich, novel output: causal, moral and aesthetic judgments. (shrink)

Contemporary philosophers frequently assume that Kant never seriously engaged with Spinoza or Spinozism --certainly not before the break of Der Pantheismusstreit, or within the Critique of Pure Reason. Offering an alternative reading of key pre-critical texts and to some of the Critique's most central chapters, Omri Boehm challenges this common assumption. He argues that Kant not only is committed to Spinozism in early essays such as "The One Possible Basis" and "New Elucidation," but also takes up Spinozist metaphysics as Transcendental (...) Realism's most consistent form in the Critique of Pure Reason. (shrink)

In the Introduction to the Treatise Hume very enthusiastically announces his project to provide a secure and solid foundation for the sciences by grounding them on his science of man. And Hume indicates in the Abstract that he carries out this project in the Treatise. But most interpreters do not believe that Hume's project comes to fruition. In this paper, I offer a general reading of what I call Hume's ‘foundational project’ in the Treatise, but I focus especially on Book (...) 1. I argue that in Book 1 much of Hume's logic is put in the service of the other sciences, in particular, mathematics and natural philosophy. I concentrate on Hume's negative thesis that many of the ideas central to the sciences are ideas that we cannot form. For Hume, this negative thesis has implications for the sciences, as many of the texts I discuss make evident. I consider and criticize different proposals for understanding these implications: the Criterion of Meaning and the ‘Inconceivability Principle’. I introduce what I call Hume's ‘No Reason to Believe’ Principle, which I argue captures more adequately the link Hume envisions between his logic, in particular his examination of ideas, and the other sciences.

The paper addresses two difficulties that arise in Treatise 1.2.5. First, Hume appears to be inconsistent when he denies that we have an idea of a vacuum or empty space yet allows for the idea of an “invisible and intangible distance.” My solution to this difficulty is to develop the overlooked possibility that Hume does not take the invisible and intangible distance to be a distance at all. Second, although Hume denies that we have an idea of a vacuum, some (...) texts in Treatise 1.2.5 are taken by interpreters to suggest that Hume nonetheless believes that there are vacuums in nature. I discuss the relevant texts and defend the view that Hume does not in fact countenance belief in vacuums. I conclude by outlining an interpretation of Hume’s intention in the Treatise that allows us to understand his discussion of ideas as having implications for the sciences. (shrink)

With an interest in origins, it is proposed that conflict within the group can be taken as a natural focus for exploring the evolutionary development of human moral communities. Morality today involves social control but also the management of conflicts within the group. It is hypothesized that early manifestations of morality involved the identification and collective suppression of behaviours likely to cause such conflict. By triangulation the mutual ancestor of humans and the two Pan species lived in pronounced social dominance (...) hierarchies, and made largely individualized efforts to damp conflict within the group, exhibiting consolation, reconciliation, and active pacifying intervention behaviour. It is particularly the active interventions that can be linked with social control as we know it. It is proposed that when this process became collectivized, and when language permitted the definition and tracking of proscribed behaviour, full-blown morality was on its way. Because early humans lived in egalitarian bands, a likely candidate for the first behaviour to be labelled as morally deviant is not the incest taboo but bullying behaviour, of the type that egalitarian humans today universally proscribe and suppress.

Drawing on Descartes' account of générosité, a reinterpretation of the Cogito is offered, emphasizing the role of the will. The paper's first part focuses on Cartesian ethics. It is argued that Descartes can be viewed as a Stoical thinker rather than a Baconian one. That is, he holds that theoretical contemplation is itself the primary ground of human happiness and tranquility of mind – experienced as the feeling of générosité. The paper's second part draws on the first in accounting for (...) the relation between radical doubt and certainty. By engaging with doubt, it is argued, the meditator comes to experience générosité, assert freedom. This experience is not, then, as argued by some, merely the Cogito's ethical counterpart. It is rather the Cogito's foundation. The meditator's assertion sum follows from – insofar as freedom is, as the definition of générosité asserts, ‘the only thing truly belonging to us', it consists in – the assertion of freedom.

: The question of Kant’s relation to Spinozist thought has been virtually ignored over the years. I analyze Kant’s pre-critical ‘possibility-proof’ of God’s existence, elaborated in the Beweisgrund, as well as the echoes that this proof has in the first Critique, in beginning to uncover the connection between Kant’s thought and Spinoza’s. Kant’s espousal of the Principle of Sufficient Reason [PSR] for the analysis of modality during the pre-critical period committed him, I argue, to Spinozist substance monism. Much textual evidence (...) suggests that he was aware of this commitment. However, by transforming the PSR into a regulative principle the critical Kant has transformed his pre-critical proof into a regulative ideal. He is thereby committed, I argue, to regulative Spinozism. (shrink)

What is the source of normativity in Hume’s account of causal reasoning? In virtue of what are causal beliefs justified for Hume? To answer these questions, the literature appeals, almost invariably, to custom or some feature thereof. I argue, in contrast, that causal beliefs are justified for Hume because they issue from experience. Although he denies experience the title of justifying reason, for Hume experience has normative authority. I offer an interpretation of the source and nature of the normativity of (...) experience in causal reasoning. I argue that the senses and memory have a special, positive status within the mind in virtue of their force and vivacity, which, on my reading, Hume identifies with a sense of presentness and a strong effect on the mind. Hume dignifies the system of memory and the senses with the title of reality because of these features. Causal beliefs are dignified as “realities” because they issue from reality. However, because the imagination can sometimes enhance the force and vivacity of ideas without the help of experience, Hume appeals to coherence and general rules as well. (shrink)

[1.] Husserl-Studien -- 2. Bd. Studien zur Phänomenologie der Epoché.

Kant's attack on metaphysics consists in large part in his attack on a principle that he names the Supreme Principle of Pure Reason. This principle, it is not often noticed, is the Principle of Sufficient Reason [PSR]. In interpreting this principle as such, I argue that Kant's attack on the PSR depends on Kant's claim that existence is not a first-order predicate. If existence isn't what Kant calls a real predicate, the PSR is false. While this constitutes a powerful Kantian (...) argument against dogmatic rationalism, it also poses a problem for Kant. For, as I argue, if the PSR is true, Kant's argument that existence isn't a first-order predicate is false. In this sense, Kant's attack on the PSR is begging the question vis-á-vis radical metaphysicians. Concluding the paper I suggest relying on Kant's 'is'/'ought' distinction in avoiding this circularity, thereby reinforcing the Kantian critique. (shrink)

Disgust is reasoned to operate in conjunction with the immune system to help protect the body from illness. However, less is known about the factors that impact the degree to which individuals invest in pathogen avoidance (disgust) versus pathogen management (prophylactic immunological activity). Here, we examine the role that one’s control over pathogen contact plays in resolving such investment trade-offs, predicting that (a) those from low control environments will invest less in pathogen-avoidance strategies and (b) investment in each of these (...) two strategies will occur in a compensatory fashion (i.e. they will be traded off with one other). Across four studies, we found support for these predictions, using a variety of manipulations and measures. By providing novel insights into how one’s control over pathogen exposure influences disgust sensitivity and immune system activity, the current research poses an important contribution to the literature on disgust, pathogen avoidance, and the immune system.

The article traces out the history of the evolution in meaning of the phenomenological reduction in husserl's writings. The starting point is husserl's conviction that what is lacking most to philosophy as well as to science is a truly rigorous scientific method. Already in the "logical investigations" (1901) the phenomenological reduction is presented as the core of this method. But here this reduction is understood as a deliberate restriction or limitation of the mind to what is adequately perceived in an (...) "adequately fulfilling intuition" within the immanence of consciousness, Excluding any transcendence. In his lectures on "the idea of phenomenology" a significant expansion of the notion of reduction begins to appear. There is still the insistence on the absolutely given, But this now begins to include a certain "real transcendence" extending beyond the sphere of "real immanence to consciousness." this change appears first in his published works in the "ideas" of 1913.

Research studies on Corporate Social Responsibility often focus on revealing corporate leaders’ attitudes toward various issues of CSR. The position of the present paper is that to understand CSR, we must grasp the collaborative perspective of CSR, and discern the attitudes of community leaders as well as corporate leaders. To this end, the study compares attitudes of community leaders with those of corporate leaders in three localities in Israel. The study examines various issues of CSR, highlighting the benefits to both (...) community and corporation of reciprocal relations. Results from t‐tests confirmed significant differences between the groups. Some important implications for CSR particularly in terms of collaboration between community and corporation are discussed.

Hume’s views concerning the existence of body or external objects are notoriously difficult and intractable. The paper sheds light on the concept of body in Hume’s Treatise by defending three theses. First, that Hume’s fundamental tenet that the only objects that are present to the mind are perceptions must be understood as methodological, rather than metaphysical or epistemological. Second, that Hume considers legitimate the fundamental assumption of natural philosophy that through experience and observation we know body. Third, that many of (...) the contradictions and difficulties that interpreters attribute to Hume’s concept of body should be attributed instead, as Hume does, to every system of philosophy.

In his discussion of our idea of time in the Treatise, Hume makes the perplexing claim that unchanging objects cannot be said to endure. While Hume is targeting the Newtonian conception of absolute time, it is not at all clear how his denial that unchanging objects are in time fits with this target. Moreover, Hume diagnoses our belief that unchanging objects endure as the product of a psychological fiction, but his account of this fiction is also riddled with puzzling claims (...) about our experience of unchanging objects. In this paper, we argue that Hume’s claims are a lot less baffling and indeed, much more sophisticated than they appear. We do so by considering his arguments as a response to Locke’s specific approach to the concept of absolute time. (shrink)

Scholars commonly assume that Kant never seriously engaged with Spinoza or Spinozism. However, in his later writings Kant argues several times that Spinozism is the most consistent form of transcendental realism. In the first part of the paper, I argue that the first Antinomy, debating the age and size of the world, already reflects Kant's confrontation with Spinozist metaphysics. Specifically, the position articulated in the Antithesis ? according to which the world is infinite and uncreated ? is Spinozist, not Leibnizian, (...) as commonly assumed. In the second part of the paper, I raise the chief Spinozist challenge to the Antinomy, arising from Spinoza's reliance on a cosmological `totum analyticum' ? an infinite whole which is prior to its parts. In conclusion, I begin to elaborate a defence of the Kantian position, confronting Spinoza's infinite whole with Kant's account of the absolutely infinite in his discussion of the sublime. (shrink)

Proponents of the standard evolutionary biology paradigm explain human “altruism” in terms of either nepotism or strict reciprocity. On that basis our underlying nature is reduced to a function of inclusive fitness: human nature has to be totally selfish or nepotistic. Proposed here are three possible paths to giving costly aid to nonrelatives, paths that are controversial because they involve assumed pleiotropic effects or group selection. One path is pleiotropic subsidies that help to extend nepotistic helping behavior from close family (...) to nonrelatives. Another is “warfare”—if and only if warfare recurred in the Paleolithic. The third and most plausible hypothesis is based on the morally based egalitarian syndrome of prehistoric hunter-gatherers, which reduced phenotypic variation at the within-group level, increased it at the between-group level, and drastically curtailed the advantages of free riders. In an analysis consistent with the fundamental tenets of evolutionary biology, these three paths are evaluated as explanations for the evolutionary development of a rather complicated human social nature.

Hume appeals to different kinds of certainties and necessities in the Treatise. He contrasts the certainty that arises from intuition and demonstrative reasoning with the certainty that arises from causal reasoning. He denies that the causal maxim is absolutely or metaphysically necessary, but he nonetheless takes the causal maxim and ‘proofs’ to be necessary. The focus of this paper is the certainty and necessity involved in Hume’s concept of knowledge. I defend the view that intuitive certainty, in particular, is certainty (...) of the invariability or necessity of relations between ideas. Against David Owen and Helen Beebee, I argue that the certainty involved in intuition depends on the activity of the mind. I argue, further, that understanding this activity helps us understand more clearly one of Hume’s most important theses, namely that experience is the source of a distinct kind of certainty and of necessity.

Understanding aging and how it affects an organism's lifespan is a fundamental problem in biology. A hallmark of aging is stem cell senescence, the decline of functionality, and number of somatic stem cells, resulting in an impaired regenerative capacity and reduced tissue function. In addition, aging is characterized by profound remodeling of the immune system and a quantitative decline of adequate immune responses, a phenomenon referred to as immune‐senescence. Yet, what is causing stem cell and immune‐senescence? This review discusses experimental (...) studies of potentially immortal Hydra which have made contributions to answering this question. Hydra transcription factor FoxO has been shown to modulate both stem cell proliferation and innate immunity, lending strong support to a role of FoxO as critical rate‐of‐aging regulator from Hydra to human. Constructing a model of how FoxO responds to diverse environmental factors provides a framework for how stem cell factors might contribute to aging. (shrink)

Hunter-gatherer punishment involves costs and benefits to individuals and groups, but the costs do not necessarily fit with the assumptions made in models that consider punishment to be altruistic – which brings in the free-rider problem and the problem of second-order free-riders. In this commentary, I present foragers' capital punishment patterns ethnographically, in the interest of establishing whether such punishment is likely to be costly; and I suggest that in many cases abstentions from punishment that might be taken as defections (...) by free-riders are actually caused by social-structural considerations rather than being an effect of free-rider genes. This presentation of data supplements the ethnographic analysis provided by Guala. (shrink)

The last few decades have witnessed intense debates in Hume scholarship concerning Hume’s account of causation. At the core of the “old–new Hume” debate is the question of whether causation for Hume is more than mere regularity, in particular, whether Hume countenances necessary connections in mind-independent nature. This chapter assesses this debate against the background of Hume’s “foundational project” in the Treatise. The question of the role and import of Hume’s account of the idea of cause is examined and compared (...) with Hume’s treatment of other ideas. (shrink)

Living organisms are exposed to numerous influencing factors. This holds also true for their infrastructures that are processing and transducing information like endocrine networks or nerval channels. Therefore, the ability to compensate for noise is crucial for survival. An efficient mechanism to neutralise disturbances is instantiated in form of parallel complementary communication channels exerting antagonistic effects at their common receivers. Different signal processing types share the ability to suppress noise, to widen the system’s regulation capacity, and to provide for variable (...) gains while leaving the transferred signal to a large extent unchanged.

Many proteins responsible for genome maintenance interact with one another via short sequence motifs. The best known of these are PIP motifs, which mediate interactions with the replication protein PCNA. Others include RIR motifs, which bind the translesion synthesis protein Rev1, and MIP motifs, which bind the mismatch repair protein Mlh1. Although these motifs have similar consensus sequences, they have traditionally been viewed as separate motifs, each with their own target protein. In this article, we review several recent studies that (...) challenge this view. Taken together, they imply that these different motifs are not distinct entities. Instead, there is a single, broader class of motifs, which we call “PIP‐like” motifs, which have overlapping specificities and are capable of binding multiple target proteins. Given this, we must reassess the role of these motifs in forming the network of interacting proteins responsible for genome maintenance. (shrink)

Nach wissenschaftlichen Schätzungen gibt es auf diesem Planeten Menschen seit etwa einer halben Million Jahre. Gleichwohl drohen die überall um sich greifenden, scheinbar aus den verschiedensten Quellen sich nährenden Vorstellungen universaler Entwicklung der Behauptung, daß solche Wesen—Menschen—wirklich existieren, den Boden zu entziehen. Denn diese Behauptung muß bedeuten, daß mit dem Auftreten von Menschen—als Wesen eigener Art—ein ihnen spezifisch eigenes, zuvor ungekanntes Wirkungsvermögen in die Welt eingetreten ist und, soweit es reicht und sich auswirkt, die Wirklichkeit dieser Welt verändert hat. Solche (...) Veränderungen der Welt im Wirkungsbereich des Menschen und in Folge seiner insbesondere auf seine Wissenschaft sich stützenden Wirksamkeit scheinen ja auch sichtbar genug. Doch gerade im Namen dieser ihrer Wissenschaft wollen moderne Menschen diese Veränderungen eher nur der Entwicklung zuschreiben als einem geheimnisvollen Wirkungsvermögen ganz eigenartiger Wesen, die da mitten unter uns unter dem Namen von “Menschen” existierten, ja denen man gar uns selber zurechnen wollte.

Levinas' Heidegger-Kritik, der in seinem Totalité et Infini zweifellos grundlegende Bedeutung zukommt, stürzt zunächst in Verwirrung : der Begriff der Totalität, in dem nach Levinas Heideggers ontologisches Denken befangen bleibt, scheint nur ein solcher für das Sein des Seienden als solchen und im Ganzen zu sein, Levinas' Idee eines diese Totalität transzendierenden „Unendlichen” aber eher Heideggers Gedanken des Seins selbst nahezukommen ; der Unterschied zwischen Totalität und Unendlichem, den Levinas begründet, scheint fast ein Gleiches zu bedeuten wie die „ontologische Differenz” (...) bei Heidegger, hinwiederum aber bleibt für Levinas das Sein offenbar die bloße Totalität des Seienden, indessen es ein Seiendes par excellence, nämlich der Andere ist, das unendlich die Totalität übersteigt, auf die alle Ontologie das Sein des Seienden reduziert. Aber die reduktiven Tendenzen in Heideggers ontologischem Denken, auf die Levinas kritisch hinweist, sind in der Tat unverkennbar ; sie finden ihren schärfsten Ausdruck in Heideggers ausdrücklicher Zurückweisung der Ethik als einer eigenständigen philosophischen Aufgabe. Die zur Debatte stehenden Positionen lassen sich klären im Rückgang auf Husserl : dessen Denken scheint zwiegespalten zwischen der Reduktionsforderung, die hervorgeht aus dem Verlangen nach einem absolut Gegebenen als „adäquat” Gegebenem, und dem Festhalten an der Gegebenheit auch von solchem, was nie adäquat gegeben sein kann, als einer „originären”. Vielleicht trifft es zu, daß Heidegger bei all seiner Kritik am Begriff der Wahrheit als Adäquation doch aufs entschiedenste Husserls Tendenz zum Rückgang auf adäquate Gegebenheit, also die Tendenz der Reduktion vertieft hat, indessen Levinas -nach dem Vorgange von Merleau-Ponty -strenger auf dem eigenen Rechtsgrund des inadäquat Gegebenen als eines Ursprünglichen besteht. Hier geht es vor allem um die „Gegebenheit” des Anderen, die nach Levinas in primärer und originärer Weise ein moralisches Verhalten fordert -auch und gerade schon da, wo es sich „zunächst” um die „bloße Erkenntnis” des Anderen handelt. So ist es schließlich Levinas' Idee, daß überhaupt die Ethik die philosophische Funktion der notwendigen Selbstkritik aller Philosophie hat, in der diese ihre Geschlossenheit durch das Ausbleiben des Anderen unendlich in Frage zu stellen aufgefordert ist. Mag Levinas' Heidegger-Kritik in gewissem Sinne selbst sich auf einen Gedanken gründen, der Heideggers Idee der ontologischen Differenz verwandt ist, mögen ohne den Blick auf diese Idee die Streitfragen undeutlich bleiben, die jene Kritik aufwirft, es sind doch Fragen, die in ein Dunkel eindringen, das der „ontologischen” Aufhellung sich bislang entzogen hat.

Insbesondere von LEIBNIZ her der Prägung der Grundbegriffe nach gehend, in denen sich die neuzeitliche "Metaphysik der Subjektivität" begründet hat, geriet.der Verfasser in Verlegenheit, als er das Ver hältnis des Begriffs des "Subjekts" (subjectum) zu dem der "Substanz" (substantia) zu fassen suchte. Nicht nur bedeutet, wie bekannt, das Wort subjectum im "Mittelalter" etwas anderes als das Wort "Subjekt" in der "Neuzeit", sondern auch jenes Verhältnis, erwies sich, ist zumal in der theologischen Ontologie der Hochscholastik, aber auch noch in der Begrifflichkeit (...) der ersten "Systeme" der neuzeitlichen Metaphysik, ein anderes, als es der heutigen, seit KANTs Zeiten sich verbreitenden Meinung geläufig ist.! Für THOMAS VON AQUINO stehen zusammen: 2 pati, recipere, subjectum esse. Es war unumgänglich, auf ARISTOTELES zurückzugehen, der jenen Begriff des U7t"OXe:LfLe:VOV, von dem sich der des subjectum und so auch der des Subjekts herleitet, zuerst geprägt hat. Hier wiederum konnte es nicht ausbleiben, daß seine den "Begriff und die Ontologie des Subjekts" betreffenden Studien den Verfasser in andere Fragen verwickelten, die eine selbständige Untersuchung erforderten.

Interpreters have found it exceedingly difficult to understand how Hume could be right in claiming that his two definitions of ‘cause’ are essentially the same. As J. A. Robinson points out, the definitions do not even seem to be extensionally equivalent. Don Garrett offers an influential solution to this interpretative problem, one that attributes to Hume the reliance on an ideal observer. I argue that the theoretical need for an ideal observer stems from an idealized concept of definition, which many (...) interpreters, including Garrett, attribute to Hume. I argue that this idealized concept of definition indeed demands an unlimited or infinite ideal observer. But there is substantial textual evidence indicating that Hume disallows the employment of idealizations in general in the sciences. Thus Hume would reject the idealized concept of definition and its corresponding ideal observer. I then put forward an expert-relative reading of Hume’s definitions of ‘cause’, which also renders both definitions extensionally equivalent. On the expert-relative reading, the meaning of ‘cause’ changes with better observations and experiments, but it also allows Humean definitions to play important roles within our normative practices. Finally, I consider and reject Henry Allison’s argument that idealized definitions and their corresponding infinite minds are necessary for expert reflection on the limitations of current science.
