Naturbegriffe beschreiben naturphilosophische Gegenstandsbereiche und fassen Resultate naturphilosophischer Diskurse zusammen. Gehört ihre Bestimmung zu den grundlegenden Aufgaben der Naturphilosophie, so stellt ihre gegenwärtige Vielfalt für die Naturphilosophie eine Herausforderung dar, Von kaum einer wirkungsgeschichtlich bedeutsamen Definition von Natur ist in den letzten Jahrzehnten behauptet worden, ihr komme keine Relevanz für den Diskurs zu. Der Beitrag zeigt Ordnungsstrukturen in der Pluralität der Verwendungsweisen auf und begründet den aktuellen Geltungsanspruch traditioneller Begriffe im Bezug auf spezifische Erfahrungsweisen. Nach einer Einführung beginne ich mit (...) der Unterscheidung von wissenschaftlicher und nichtwissenschaftlicher Naturerfahrung, beziehe auf diese Differenz die Aufgaben der Naturphilosophie und gehe dann mit einer Klassifikation von Naturbegriffen zum exemplarischen Teil über. In diesem diskutiere ich am Beispiel bestimmter Aspekte der Naturbegriffe von Aristoteles und Descartes ihre für die Gegenwart typischen Bedingungen der Verwendung in nichtwissenschaftlicher Erfahrung sowie darüber hinaus vorkommender Verwendungen.

Die Traume und Visionen aus der antiken Literatur, die die romischen Kaiser und ihr Umfeld betreffen, wurden bislang noch nicht auf ihre Bedeutung hin untersucht. Die vorliegende Arbeit schliesst diese Lucke, indem sie das Material von Caesar bis Maurikios analysiert. Dabei ergeben sich spezifische Motive, die besonders mit Traumen und Visionen verbunden sind: Geburt und Kindheit, Verheissung der Herrschaft, Erringung eines Sieges und gottliches Eingreifen, Ausubung der Herrschaft, besondere Befahigung und gottliche Begunstigung, nahendes Ende. Durch den breiten zeitlichen Ansatz gelingt (...) es, fur die Motive unterschiedliche Schwerpunkte auszumachen: Sie stehen alle in der Spannung zwischen einer gezielten Verbreitung zur Schaffung von Akzeptanz und der Literarisierung durch die antiken Autoren. Fur die Behandlung der Thematik waren nicht nur definitorische Vorarbeiten notwendig, sondern auch der mentale Horizont moglicher Rezipienten musste durch die Interpretation von Inschriften, Papyri und Selbstaussagen antiker Autoren in den Blick genommen werden.

Examining developments in two of the central traditions of social and political theory - Marxism and pluralism, this work investigates whether the relation between them is one of progressive convergence.

Im ersten Teil verorte ich den historischen Kontext des Umbruchprozesses der Wissenschaft des 19. Jahrhunderts im Hinblick auf die Physik. Vom Beginn der Neuzeit bis weit ins 20. Jahrhundert hinein war die Physik die Leitwissenschaft in den Naturwissenschaften. Der Wandlungsprozess der auf sie bezogenen Wissenschaftsauffassungen setzt im 19. Jahrhundert bislang unangetastete, von der Antike herrührende Geltungsansprüche außer Kraft. Im zweiten Teil vergleiche ich Nietzsches Charakterisierung der Wissenschaften exemplarisch mit der von Hermann von Helmholtz. Helmholtz kann als ein herausragender Vertreter der (...) Naturforschung des 19. Jahrhunderts angesehen werden. Er entwickelte seine erste bahnbrechende wissenschaftliche Leistung noch ganz im Rahmen einer auf Wahrheit und Einheit fokussierten Wissenschaftsauffassung. Im Verlauf seiner weiteren Arbeiten relativierten sich seine Geltungsansprüche zunehmend. In systematischer Hinsicht näherte sich Helmholtz damit nicht nur der Position an, die Nietzsche immer schon eingenommen hat, sondern er übertraf sie sogar in bestimmter Hinsicht. -/- Im dritten Teil setze ich mich kritisch mit einem Aspekt der Rezeption des historischen Verhältnisses von Nietzsche und Helmholtz auseinander. Helmholtz gehörte zu den wenigen repräsentativen Naturwissenschaftlern, von denen man annimmt, dass ihre Forschungen auf das Denken Nietzsches Einfluss hatten. Bemerkenswerterweise stammen die betreffenden Arbeiten aus der ersten Phase von Helmholtz’ Wissenschaftsauffassung. Während Helmholtz mit seinen Forschungen einen traditionellen Wahrheitsanspruch bestätigt sah, bezog sich Nietzsche auf sie, um sie umgekehrt zur Destruktion dieses Anspruches einzusetzen. Wo der Rezeption diese Konstellation entgangen ist, hat sie dazu beigetragen, die Aktualität von Nietzsches Wissenschaftskritik zu überschätzen. (shrink)

This collection of essays by Gregor Sebba (1905-1985) reflects the curiosity and insight of his mind. The range of topics is wide, including philosophy and the history of ideas, literature and art; yet there is a single underlying theme - human creativity and the search for truth - pursued along paths as diverse as Greek tragedy, Eric Voegelin's concept of order in history, and the poetry of Rainer Maria Rilke and T.S.Eliot.

There is increasing evidence for the wide‐spread existence of functionally redundant genetic pathways in developmental processes. However, both their significance and manner of evolution are still matters of debate. I will argue here that redundancy of gene actions may, in fact, be a necessary requirement for the development and evolution of complex life forms. One can view development as a process that transmits information from the egg to the adult organism. Transmission of information is, however, always an error‐prone process, which (...) can only be safeguarded by including redundancies in the message. Molecular examples for well analysed redundant processes indicate that redundancies may best be understood within a conceptual framework of overlaps between different gene functions. (shrink)

Die Entwicklung von HeImholtz' Mechanismus ist durch einen Wandel im Geltungsanspruch gekennzeichnet und läßt sich in einer noch sehr groben Übersicht in zwei Perioden einteilen. Auf die erste Periode bis etwa zum Ende der 60er Jahre werde ich im ersten Teil meines Beitrages eingehen. Hier rekonstruiere ich umrißhaft die empiristische Begründung, die Helmholtz für den Wahrheitsanspruch seiner Naturauffassung gegeben hat. Im zweiten Teil werde ich dann die wichtigsten Merkmale der im Verlauf der 70er Jahre hervortretenden Hypothetisierungstendenz charakterisieren. Abschliessend will ich (...) in einem dritten Teil zeigen, wie Helmholtz auf der Grundlage seines gewandelten Wissenschaftsverständnisses das Programm einer mechanistischen Naturerklärung mit großem wirkungsgeschichtlichen Einfluß weiter verfolgt hat.

Ich thematisiere die beiden Konzeptionen als Varianten der wissenschaftlichen Weltsicht. Der Reiz des Vergleichs liegt aber weniger in den Gemeinsamkeiten als vielmehr in den Differenzen und den dabei hervortretenden Desideraten der beiden Konzeptionen. Heisenberg versteht sein Schichtenmodell nicht wie Hartmann als Fortsetzung und Zusammenfassung vorangehender philosophischer Bemühungen, sondern als einen Bruch mit den Hauptströmungen der philosophischen Tradition. In der geschichtlichen Entwicklung der Versuche um eine Bestimmung der Weltstruktur sieht er statt einer Generaltendenz, die langfristig auf eine Annäherung an die Wahrheit (...) hinausläuft, tiefgreifende Diskontinuitäten zwischen den aufeinanderfolgenden epochalen Thematisierungsmöglichkeiten. Heisenbergs Motivation für die Suche nach einer Weltordnung ist den Intentionen von Hartmann damit geradezu entgegengesetzt. Er fragt nicht nach einer epochenübergreifenden Orientierung, sondern nach einer epochenspezifischen Charakterisierung der Welt, deren zukünftig möglicher Geltungsverlust zum Maßstab neuer historischer Umbruchsphasen wird. -/- Die Desiderate der beiden Schichtenkonzeptionen gehen teils auf die nachfolgende Entwicklung der einzelwissenschaftlichen Erkenntnis, teils auf den seitherigen Wandel der auch alltagspraktisch wirksamen kulturellen Selbstverständlichkeiten zurück. Einige Schwächen könnten durch Anpassung an veränderte Wissensbedingungen behoben werden. In diesem Zusammenhang schlage ich die Einführung zweier neuer Schichten vor: Die subatomare Schicht der Quantenobjekte und die Schicht der in kosmischen Dimensionen wirksamen Materie- und Energieformen. Es lassen sich aber auch grundlegende Bedenken formulieren, die in Richtung einer Ordnung der Wirklichkeit weisen, die keiner Schichtenauffassung mehr folgt. (shrink)

The ideal of value free science states that the justification of scientific findings should not be based on non-epistemic (e.g. moral or political) values. It has been criticized on the grounds that scientists have to employ moral judgements in managing inductive risks. The paper seeks to defuse this methodological critique. Allegedly value-laden decisions can be systematically avoided, it argues, by making uncertainties explicit and articulating findings carefully. Such careful uncertainty articulation, understood as a methodological strategy, is exemplified by the current (...) practice of the Intergovernmental Panel on Climate Change (IPCC). (shrink)

Gregor Moder’s Hegel and Spinoza: Substance and Negativity is a lively entry into current debates concerning Hegel, Spinoza, and their relation. Hegel and Spinoza are two of the most influential philosophers of the modern era, and the traditions of thought they inaugurated have been in continuous dialogue and conflict ever since Hegel first criticized Spinoza. Notably, eighteenth- and nineteenth-century German Idealists aimed to overcome the determinism of Spinoza’s system by securing a place for the freedom of the subject within (...) it, and twentieth-century French materialists such as Althusser and Deleuze rallied behind Spinoza as the ultimate champion of anti-Hegelian materialism. This conflict, or mutual rejection, lives on today in recent discussions about materialism. Contemporary thinkers either make a Hegelian case for the productiveness of concepts of the negative, nothingness, and death, or in a way that is inspired by Spinoza they abolish the concepts of the subject and negation and argue for pure affirmation and the vitalistic production of differences. Hegel and Spinoza traces the historical roots of these alternatives and shows how contemporary discussions between Heideggerians and Althusserians, Lacanians and Deleuzians are a variation of the disagreement between Hegel and Spinoza. Throughout, Moder persuasively demonstrates that the best way to read Hegel and Spinoza is not in opposition or contrast but together: as Hegel and Spinoza. (shrink)

The principle of performative contradiction. On the epistemological significance of the dialogue form in Plato's "Euthydemus". - In this study, an analysis of the section 285d-288a of Plato's "Euthydemus" shall show two things: (1) The sophistic model of a world in which there is no contradiction, in which every linguistic utterance is true and every action correct, has no semantic inconsistencies, but can only be rejected with the help of the principle of performative contradictions. (2) It is precisely these performative (...) contradictions that make it necessary for Plato to philosophize not in treatises but in dialogues; in other words, that the philosophical relevance of the Platonic form of dialogue can be seen, among other things, in the fact that - in contrast to philosophical forms of representation such as the treatise, the essay, and a henology as reconstructed and represented by the Tübingen School - it permits the representation of performative reflections and performative contradictions.

How does microbiota research impact our understanding of biological individuality? We summarize the interdisciplinary summer school on "Microbiota, Symbiosis and Individuality: Conceptual and Philosophical Issues" (July 2019), which was supported by a European Research Council starting grant project "Immunity, DEvelopment, and the Microbiota" (IDEM). The summer school centered around interdisciplinary group work on four facets of microbiota research: holobionts, individuality, causation, and human health. The conceptual discussion of cutting-edge empirical research provided new insights into microbiota and highlights the value of (...) incorporating into meetings experts from other disciplines, such as philosophy and history of science.

Gap genes stand at the top of the zygotic segmentation hierarchy in Drosophila. Their expression domains are set up by a combination of maternal regulatory signals and interactions among themselves. In addition, these regulatory pathways are partially redundantly specified by the maternal and zygotic genomes, or by multiple zygotic gene products. The gap genes code for transcription factors which exert their function by foming short‐range morphogenetic gradients; differential concentrations of these transcription factors can either act as activators or as repressors (...) for the expression domains of neighbouring genes. It is possible to view the gap genes as a system of genes that subdivides the embryo by forming an activation‐repression cascade proceeding from anterior towards posterior. (shrink)

The aim of this paper is to develop and defend an Attentional View of bodily awareness, on which attention is necessary for bodily awareness. The original formulation of the Attentional View is due to Marcel Kinsbourne. First, I will show that the Attentional View of bodily awareness as formulated by Kinsbourne is superior to other accounts in the literature for characterizing the relationship between attention and bodily awareness. Kinsbourne’s account is the only account in the literature so far which can (...) accommodate key neurological diseases such as personal neglect. Second, when I consider Kinsbourne’s view in more detail, I will argue that Kinsbourne’s Attentional View faces problems because it is too reductive. Kinsbourne deviates from the standard taxonomy on which there is a body schema and a body image. Instead he reduces the body image to the neural representation of the body in the somatosensory cortex, the body schema and attentional shifts. I will present two challenges to Kinsbourne’s view which demonstrate that Kinsbourne’s reduction of the body image is unsuccessful. Finally, I will present a revised version of the Attentional View that is both empirically adequate and philosophically satisfactory. (shrink)

By means of multi-agent simulations, it investigates the truth and consensus-conduciveness of controversial debates. The book brings together research in formal epistemology and argumentation theory.

Advancements in scientific research and technological development influence the practice of organ donation and organ transplantation. Many SRTD governance discourses put forward the need for multi-stakeholder engagements. We posit that staff employed by organ procurement organizations have a stake in the discussions around SRTD applicable to ODOT because SRTD is one factor that shapes ODOT and because staff are involved in ODOT education and awareness raising while acting as a nexus between donors and the public. Therefore, we performed a content (...) analysis of eight semi-structured in-depth interviews with staff of one Canadian organ procurement organization to ascertain the views that staff had on the use of SRTD in ODOT in general; specific SRTD envisioned to be used in the future in ODOT namely xenotransplantation, embryonic and non-embryonic stem cells, cloning, bionic/artificial organs, and 3-D printed organs; and the emerging ability of SRTD applicable in ODOT to enhance bodily abilities beyond the normal. We found that staff had views on the topics covered in this study, and staff acknowledged that they do not possess sufficient knowledge to be able to engage meaningfully in governance discussions of the SRTD covered and to educate others on these SRTDs. We recommend implementing continuous education for the staff on SRTD envisioned to be applied in ODOT as a capacity-building measure to enable their participation in the governance discussions of these SRTDs and to enhance their ability to educate others on ODOT applicable SRTD.

We discuss, within the framework provided by a recently developed variational method, transposition-invariant field equations for unified field theories. Systems that are, in addition, invariant under Weyl-type gauge transformations or lambda transformations are derived. It is found that in a weak field limit two of the systems contain the equations of general relativity and the covariant Maxwell equations for a charge-free region.

Gregor Betz explores the following questions: Where are the limits of economics, in particular the limits of economic foreknowledge? Are macroeconomic forecasts credible predictions or mere prophecies and what would this imply for the way economic policy decisions are taken? Is rational economic decision making possible without forecasting at all?

In this article, I engage with three overlapping expressions of the increasingly postsecular cast of social and cultural theory. These currents — guided, respectively, by genealogical critique, neo-vitalist social philosophy and postcolonial anti-historicism — seek to problematize the frame of previous radical theorizing by exposing definite connections between the epistemological and political levels of secular understanding, and by assuming that the nature of those linkages counts heavily against secularism. As well as offering an interpretive overview of these contributions, I suggest (...) that they are traversed by a number of conceptual flaws and inconsistencies. The tensions, I argue, stem from the fact that in spite of appearing to be driven by a strong anti-secular thrust, these positionings remain thoroughly intra-secular in character. This needs to be more emphatically acknowledged if the ‘postsecular turn’ is to be productive. (shrink)

When does a human being begin to exist? Barry Smith and Berit Brogaard have argued that it is possible, through a combination of biological fact and philosophical analysis, to provide a definitive answer to this question. In their view, a human individual begins to exist at gastrulation, i. e. at about sixteen days after fertilization. In this paper we argue that even granting Smith and Brogaard's ontological commitments and biological assumptions, the existence of a human being can be shown to (...) begin much earlier, viz., with fertilization. Their interpretative claim that a zygote divides immediately into two substances and therefore ceases to exist is highly implausible by their own standards, and their factual claim that there is no communication between the blastomeres has to be abandoned in light of recent embryological research.

Husserl’s theory of fulfilment conceives of empty acts, such as symbolic thought, and fulfilling acts, such as sensory perceptions, in a strict parallel. This parallelism is the basis for Husserl’s semantics, epistemology, and conception of truth. It also entails that any true proposition can be known in principle, which Church and Fitch have shown to explode into the claim that every proposition is _actually_ known. I assess this logical challenge and discuss a recent response by James Kinkaid. While Kinkaid’s proposal (...) saves one direction of the parallel for semantics, it gives up the parallelism for truth. I spell out a different response which meshes naturally with Husserl’s account of meaning. If the parallelism is restricted to a class of basic propositions, the truth of non-basic propositions can be defined inductively, without leading to the paradox. I then discuss objections that have been raised against a similar proposal by Dummett. The result is that exegetically plausible and popular interpretations of Husserl’s correlationism are indeed challenged by Church and Fitch. But when taking into account the ‘logical adumbration’ of propositional blindspots, truth and possible fulfilment can be connected without paradox. (shrink)

A widespread view of the natural sciences holds that their historical development was accompanied by a constantly widening gap between them and magic. Originally closely bound up with magic, the sciences are supposed to have distanced themselves from it in a long-drawn-out process, until they attained their present magic-free form. I would like, in this essay, to discuss some arguments in support of this plausible view. To this end, I shall begin with a definition of magical and scientific concepts of (...) nature. To exemplify the gap which, over several epochs, widened between the magical and the scientific understanding of nature, I would like to examine two concepts in natural science, both assumed by physics. The first concept I select is Aristotle's concept of physis. It was fundamental to the emergence of physics, and sets its mark on thought in this field right up to the beginning of the modern period. The distinctive characteristic of the second concept of nature is negative, consisting in the elimination of the Aristotelian distinction between physis and techne. I consider Galileo Galilei to be a trail-blazer for this anti-magical position, as well as a co-founder of experimental science with his mechanical and astronomical works. As a conclusion I will say something of the relationship of magic to concepts of nature typical of the following period, both in physics and other natural sciences. (shrink)

Gregor Paul, Philosoph an der Universität Karlsruhe, will zeigen, “dass ein Krieg gegen den Terrorismus unmöglich wäre, wenn man gültiger Argumentation folgte”. Die Frage ist, ob es einen „gerechten Krieg“ überhaupt gibt – eine alte Frage, auf die nicht nur in der abendländischen Philosophie unterschiedliche Antworten gegeben worden sind. Paul lässt hier die alte chinesische Philosophie zu Wort kommen. An den Beispielen der Kriege in Afghanistan und Irak wie dem sogenannten Krieg gegen den Terrorismus zeigt Paul, wie für deren (...) “Gerechtigkeit” nicht nur nicht offen argumentiert, sondern eine notwendige allseitige Diskussion verhindert wurde. Erst eine solche offene Diskussion würde das Gewicht der Argumente zeigen und Paul ist überzeugt, dass die Argumente für Kriege jeglicher Art vor dem Forum der Vernunft als zu leicht befunden würden.

The overall goal of this target article is to demonstrate a mechanism for an embodied cognition. The particular vehicle is a much-studied, but still widely debated phenomenon seen in 7–12 month-old-infants. In Piaget's classic “A-not-B error,” infants who have successfully uncovered a toy at location “A” continue to reach to that location even after they watch the toy hidden in a nearby location “B.” Here, we question the traditional explanations of the error as an indicator of infants' concepts of objects (...) or other static mental structures. Instead, we demonstrate that the A-not-B error and its previously puzzling contextual variations can be understood by the coupled dynamics of the ordinary processes of goal-directed actions: looking, planning, reaching, and remembering. We offer a formal dynamic theory and model based on cognitive embodiment that both simulates the known A-not-B effects and offers novel predictions that match new experimental results. The demonstration supports an embodied view by casting the mental events involved in perception, planning, deciding, and remembering in the same analogic dynamic language as that used to describe bodily movement, so that they may be continuously meshed. We maintain that this mesh is a pre-eminently cognitive act of “knowing” not only in infancy but also in everyday activities throughout the life span. Key Words: cognitive development; dynamical systems theory; embodied cognition; infant development; motor control; motor planning; perception and action. (shrink)

In the debate about the moral status of human embryos, it is not always clear which arguments are actually disputed. This book offers students and researchers, but also laypersons interested in the current debate, the opportunity to inform themselves about the current state of discussion and to learn about the most important arguments in a clear and concise form. These arguments are as follows: Since embryos as members of the species homo sapiens sapiens are human beings, they possess dignity (species (...) argument); embryos develop continuously, i.e. without morally relevant incisions, into adult human beings possessing dignity (continuum argument); embryos are identical with adult human beings possessing dignity (identity argument); embryos have the potential to become human beings, and this potential is without restriction worth protecting (potentiality argument). These arguments are each represented by a pro position and a contra position and defended or criticized. In an accompanying contribution by the editors, the four arguments in context are reconstructed, evaluated, and supported by new arguments. (shrink)

Im vorliegenden Artikel geht Gregor Paul von einer Redeweise aus, die gerade im Zusammenhang mit interkulturellen Themen ziemlich häufig anzutreffen, in sehr vielen Fällen wohl wenig überlegt, in ihren Konsequenzen aber alles andere als harmlos ist – von der Rede über eine “andere Logik” in “anderen Kulturen” oder insbesondere über eine “östliche Logik”. Diese Rede hält Paul für unbegründet, für verhängnisvoll, und für falsch. Er identifiziert gängige Argumente und versucht, diese zu widerlegen. Im Folgenden bringt Paul einerseits Argumente für (...) die Universalität von logischen Gesetzten und detaillierte Belege für deren Annahme vor allem in Texten der chinesischen Tradition. (shrink)

The cosmological relevance of emptiness—that is, space without bodies—is not yet sufficiently appreciated in natural philosophy. This paper addresses two aspects of cosmic emptiness from the perspective of natural philosophy: the distances to the stars in the closer cosmic environment and the expansion of space as a result of the accelerated expansion of the universe. Both aspects will be discussed from both a historical and a systematic perspective. Emptiness can be interpreted as “coming” in a two-fold sense: whereas in the (...) past, knowledge of emptiness, as it were, came to human beings, in the future, it is coming, insofar as its relevance in the cosmos will increase. The longer and more closely emptiness was studied since the beginning of modernity, the larger became the spaces over which it was found to extend. From a systematic perspective, I will show with regard to the closer cosmic environment that the Earth may be separated from the perhaps habitable planets of other stars by an emptiness that is inimical to life and cannot be traversed by humans. This assumption is a result of the discussion of the constraints and possibilities of interstellar space travel as defined by the known natural laws and technical means. With the accelerated expansion of the universe, the distances to other galaxies (outside of the so-called Local Group) are increasing. According to the current standard model of cosmology and assuming that the acceleration will remain constant, in the distant future, this expansion will lead first to a substantial change in the epistemic conditions of cosmological knowledge and finally to the completion of the cosmic emptiness and of its relevance, respectively. Imagining the postulated completely empty last state leads human thought to the very limits of what is conceivable. (shrink)

The paper deals with the question of the structure of knowledge and the precise relationship between propositional "knowledge that" and dispositional "knowledge how." In the first part of my essay, I provide an analysis of the term 'knowing how' and argue that the usual alternatives in the recent epistemological debate – knowing how is either a form of propositional or dispositional knowledge – are misleading. In fact it depends on the semantic and pragmatic context of the usage of this term (...) whether 'knowing how' refers to a type of dispositional knowledge, to propositional knowledge, or to a hybrid form of both. Only in the first case, can one say that dispositional know how cannot be reduced to any form of propositional knowledge. Yet, this case is the most interesting one to consider in the investigation of the nature of knowledge, if one assumes that knowing that p presupposes "having found out that p." Having found something out, however, presupposes certain acts of epistemic inquiry and corresponding epistemic abilities. Examined more carefully, it is shown that the dispositional knowledge-how is a necessary condition for propositional knowledge-that, hence propositional knowledge-that is a species of the dispositional knowledge-how. Accordingly, dispositional knowledge has to be understood as being at the very core of our notion of knowledge, including propositional knowledge. (shrink)

This chapter goes into crucial questions related to the impact of technology on our privacy, our personal identity and our social relationships. While technology often seems extremely convenient in helping us remember things and share our experiences with others, this episode shows that it can have highly undesirable side‐effects as well. Technologies like the grain put inevitable pressures not only on privacy and trust but also on our ability to create and tell our life stories. In this chapter, we show (...) how getting to know each other's entire history and achieving full transparency about ourselves and others will likely destroy crucial and valuable aspects of our social lives.
