To explain the menstrual cycle and menopause, human biologists during the past several decades have developed new models of the evolutionary origins and maintenance of female reproductive patterns that address both ultimate and proximate causation. Hypotheses proposed for these processes generally offer explanations for menstruation or for menopause, but not for both; ultimately, these explanations must be integrated. Reviewing current explanations, this paper offers an energetics-based evolutionary rationale compatible with past adaptations of Homo sapiens and with ecological patterns in (...) small-scale, preindustrial social systems in which food resources vary and sometimes are scarce.

The human brain does not use more energy than the smaller brains of animals of comparable corporal weight. Uniquely, human functions localized largely in parts of the human brain that show greatest size increase over other animals may be mediated primarily by nonsynaptic neurotransmission, with reduced energy cost per kilogram of brain. This may affect the energetic constraints on evolution.

Cosmic rays have been a standard if mysterious phenomenon in astrophysics since the 1930s when experimental physicists first began to detect charged particles with Wilson cloud chambers and with Geiger counters and other electronic detectors. They found that energetic particles were detected even when no radioactive sources were nearby and inferred from the angles of the tracks in the cloud chambers that these particles were coming from the sky.

The energetics controversy is understood variously as energy vs. atoms, thermodynamics vs. statistical mechanics, phenomenalism vs. realism, equations vs. pictures, and especially Ostwald vs. Boltzmann. It is generally thought that at Lübeck in 1895 Boltzmann and Planck demolished energetics, but while its momentum was slowed, energetics in one or more of the above senses still retained supporters as late as the great physics conference at the St. Louis World’s Fair in 1904. Indeed, after Ostwald himself abandoned it (...) in 1908, Ernst Mach began for the first time to defend it. The main emphasis in this paper, however, is on Georg Helm (1851–1923) who had been invited to Lübeck to be the main speaker on energetics. He had adopted his position earlier than Ostwald and his views avoided many of the errors and oversights in Ostwald’s approach. Indeed, Helm could be called the strongest defender of energetics, even if Ostwald was Boltzmann’s main target. Helm was largely Machist in philosophy at that time and did not reify energy. (shrink)

The author assumes that the biological evolution must reflect itself also in the energetic processes of the organism. Several concept are discussed, in view of a characterization of the energetic economy of the organism. Two of these are thought to have particular significance related to evolution: the energetic efficiency and the capacity for energetic production . E is the ratio of the performed useful work to the amount of energy “spent”; P is the ratio of the performed useful work to (...) the product of the mass of the living system and time. An evolution of both E and P during the animal phylogenesis is assumed. The evolution of E is generally evident at the level of more elementary metabolic processes, while that of P at the level of more complex functions or of the organism as a whole. In many cases, the increase of P is associated with a decrease of E. The main evolutionary feature of biological energetic economy is the increase of the capacity for energetic production. This holds true even if the increase of P can be achieved only at the expense of a reduction of the energetic efficiency, of a “waste” of energy, especially in the most highly developed systems of the organism.L'évolution biologique doit se refléter, selon l'avis de l'auteur, aussi dans les processus énergétiques de l'organisme. On discute quelques notions qui pourraient caractériser l'économie énergétique de celui-ci. Deux de celles-ci ont une signification évolutive particulière: le rendement énergétique et la capacité de production énergétique . E est le rapport du travail util effectué à la quantité d'énergie “dépensée”; P est le rapport du travail util effectué au produit de la masse du système vivant avec de le temps. L'auteur considère qu'il y a une évolution des deux grandeurs au cours de la phylogénèse animale. L'évolution d'E se manifeste spécialement au niveau des processus métaboliques élémentaires, tandis que celle de P au niveau des fonctions plus complexes ou de l'organisme entier. Dans beaucoup de cas, l'accroissement de P entraîne une diminution de E. Le trait évolutif principal de l'énergétique biologique c'est l'accroissement de la capacité de production énergétique, même si cela suppose une réduction du rendement, une “dissipation” d'énergie, surtout dans les systèmes les plus développés de l'organisme.Die biologische Evolution soll sich, nach dem Erachten des Verfassers, auch in den energetischen Vorgange des Organismus kundtun. Es werden einige Begriffe erörtert, welche den Energiehaushalt des Organismus kennzeichnen können. Zwei von diesen Begriffen haben eine besondere entwicklungsgeschichtliche Bedeutung: die energetische Leistung und das Vermögen zur Energieproduktion . E ist das Verhältnis der geleisteten nützlichen Arbeit zur verbrauchten Energiemenge; P ist das Verhältnis der nützlichen Arbeit zum Produkt von Masse des lebenden Systems und Zeit. Der Verfasser ist der Meinung, dass es eine Evolution von E und P während der tierischen Phylogenesis gäbe. Die Evolution von E äussert sich meist in der Ebene der elementaren metabolischen Vorgänge, hingegen die von P an komplexeren Funktionen. In zahlreichen Fällen, vermindert E während P wächst. Die evolutive Grundzug der biologischen Energetik ist das Anwachsen der Fähigkeit zur Energieproduktion, sogar wenn dieses nur auf Kosten einer Verminderung der energetischen Leistung, einer „Vergeudung“ der Energie verwirklichen kann.

There are three main kinds of causal connections between two events: the transfer of energy, the transfer of information and the triggering of the transfer of one of them or both. There are also other kinds of causal connections.

Recently, Weisbecker and Goswami presented the first comprehensive comparative analysis of brain size, metabolic rate, and development periods in marsupial mammals. In this paper, a strictly energetic perspective is applied to identify general mammalian correlates of brain size evolution. In both marsupials and placentals, the duration or intensity of maternal investment is a key correlate of relative brain size, but here I show that allomaternal energy subsidies may also play a role. In marsupials, an energetic constraint on brain size in (...) adults is only revealed if we consider both metabolic and reproductive rates simultaneously, because a strong trade‐off between encephalization and offspring production masks the positive correlation between basal metabolic rate and brain size in a bivariate comparison. In conclusion, starting from an energetic perspective is warranted to elucidate relations between ecology, social systems, life history, and brain size in all mammals. (shrink)

This dissertation is meant to interpret Whitehead's basic unit of ontology in energetic terms. The actual entity is to be understood as an oscillating unit of existence that is nothing other than its oscillatory activity. There is nothing substantial underlying it: it is essentially a vibrating entity that has nothing more primary appended to it. Through such vibratory activity, it realizes itself out of its own conative drive and its deeply interrelated adventures with other entities and objects. Energizing actuality makes (...) such entities objectively stubborn, subjectively agentive, massively interrelated to others, and entirely aesthetic in constitution. There are two main ways to analyze this metaphysical energy. This is mirrored by Whitehead's twofold analysis of actuality from the genetic and coordinate perspectives, which itself is an adaptation of James's Pragmatic analysis of experience. The quantum oscillation model of atomicity perfectly matches Whitehead's genetic analysis, and thus the phases of actuality, the poles of existence, and the formation of an atomic unit, are all developed in oscillatory terms. Conversely there is the coordinate analysis, where issues of ontological rhythmicity, identity via agentive repetition, unification via cyclical patternings, and coeval concrescence among entities will be dealt with according to the principles of wave transmission. Each analysis develops important characteristics of actuality, but neither analysis on its own can capture the totality of what actuality is. For such a generic interpretation to occur, unification between the genetic and the coordinate analyses must take place. The energy thesis accomplishes this by adopting the language of energy fields. The actual entity is a field of energy that is both the center of agentive activity that defines the field, and the center of attention of other entities. Whitehead calls this ontologically agentive attention 'concern,' a term that allows Whitehead to be closely compared to Heidegger, whose existential analysis of Dasein will be used to further develop the character of actuality. The aesthetic core of Whiteheadian ontology will be developed by comparing it to Dewey's aesthetic theory of consummatory experience. Together, a fully concerned and consummatory actual entity will stand as the most generic rendering of actuality. (shrink)

In this chapter, we develop the claim that today, in light of the distributed catastrophe called the Anthropocene, the question of ethics first and foremost becomes a question of economy and energy. Supplementing existing ethical approaches to the question of economy and energy, we offer what we understand to be a more fundamental economical interpretation of the Anthropocene by way of Georges Bataille’s philosophical thought on economy. We will argue that inasmuch as it results from what has come to be (...) known as “the great acceleration”, the Anthropocene can be understood as a consequence of an economic consideration of energy that is oriented towards scarcity and utility, which is to say to Bataille’s “restricted economy”. Additionally, we show how for Bataille, such a ‘restricted’ consideration of energy is an ethical affair, since it misunderstands the constitutive abundance of energy associated with “the general economy”, thereby simultaneously and catastrophically misunderstanding the ethos of human existence in servile terms of labour and efficiency. Finally, we investigate how Bataille’s concept of sovereignty seeks to surpass such servility and efficiency by way of a consideration of energy that is oriented towards expenditure. We offer a reinterpretation of the ethics of sovereignty by confronting it with our contemporary deteriorating oikos inhabited in the Anthropocene. We close by arguing that notwithstanding its irrevocable difficulties, the question of ethics in the Anthropocene must be considered as an energetic ethics of sovereignty. (shrink)

The notions of a C-energetic subset and permeable C-value in BCK-algebras are introduced, and related properties are investigated. Conditions for an element t in [0, 1] to be an permeable C-value are provided. Also conditions for a subset to be a C-energetic subset are discussed. We decompose BCK-algebra by a partition which consists of a C-energetic subset and a commutative ideal.

Viewed from an evolutionary standpoint, emotions can be understood as situation-specific patterns of energy consumption related to behaviors that have been selected by evolution for their survival value, such as environmental exploration, flight or fight, and socialization. In the present article, the energy linked with emotions is investigated by a strictly energy-based simulation of the evolution of simple autonomous agents provided with random cognitive and motor capacities and operating among food and predators. Emotions are translated into evolving patterns of energy (...) consumption related to situation-specific behaviors. As a result, a variety of behaviors resembling emotions emerge, each with a specific pattern of energy consumption. There is little difference between emotion-like behaviors on individual and collective levels. The fact that these patterns evolve under a strictly energetic selection regime indicates the interesting role and adaptive advantage of emotions as situation-specific energy savers. Although gained through an approach characterized by a highly reduced complexity, these findings support a quantitative understanding of emotions that may improve the existing qualitative approaches and could have far-reaching implications for further research on and conceptualization of emotions and their interactions with cognition.

A semiótica ontológica de Peirce retomou o sentido de práxis racional de Aristóteles em seu sentido compartilhado da função de mediação do Interpretante lógico. O artigo está dividido em três partes. A primeira delineia a conceitualização de Ivo Assad Ibri da semiose de Peirce com relação à diferença entre o Interpretante emocional e o lógico, em especial com relação ao primeiro nos modos “degenerados” de fixação de crença e conduta; a segunda parte explica a conceitualização inicial de Peirce daquela doutrina (...) em seu tratamento do “Homem-signo” em “Some Consequences of Four Incapacities” ; a terceira parte apresenta a Ética a Nicômaco de Aristóteles como a origem clássica da trajetória principal da semiose de Peirce, ao correlacionar o conceito de teleologia de desenvolvimento de Peirce com o conceito paralelo de caráter disposicional ativo de Aristóteles energizado pela média ética como o interpretante pragmatista da conduta.

The extreme sexual size dimorphism in spiders has motivated studies for many years. In many species the male can be very small relative to the female. There are several hypotheses trying to explain this fact, most of them emphasizing the role of energy in determining spider size. The aim of this paper is to review the role of energy in sexual size dimorphism of spiders, even for those spiders that do not necessarily live in high foliage, using physical and allometric (...) principles. Here we propose that the cost of transport or equivalently energy expenditure and the speed are traits under selection pressure in male spiders, favoring those of smaller size to reduce travel costs. The morphology of the spiders responds to these selective forces depending upon the lifestyle of the spiders. Climbing and bridging spiders must overcome the force of gravity. If bridging allows faster dispersal, small males would have a selective advantage by enjoying more mating opportunities. In wandering spiders with low population density and as a consequence few male–male interactions, high speed and low energy expenditure or cost of transport should be favored by natural selection. Pendulum mechanics show the advantages of long legs in spiders and their relationship with high speed, even in climbing and bridging spiders. Thus small size, compensated by long legs should be the expected morphology for a fast and mobile male spider. (shrink)

This essay has three interrelated goals: first, to sketch the basic contours of Georg Helm's energetic theory; second, to describe his attempt in his Grundzüge der mathematischen Chemie. Energetik der chemischen Erscheinungen (1894) to apply that theory to the (then) burgeoning new field of physical chemistry. This is of some interest historically, since Helm's work is the most sophisticated attempt to develop the whole of physical chemistry mathematically from an energetic point of view. Nevertheless, it is seriously flawed technically. Moreover, (...) that development is inconsistent with Helm's considered way of thinking about energy and energetic change. So a third goal of the essay is to explain his mature conception of the goal of energetics. I begin with a brief introduction to Helm and energetics, and end with some general conclusions about the success of Helm's mathematische Chemie. (shrink)

At the turn of the twentieth century, Helm and Ostwald were the most prominent supporters of so-called ‘energetics’, which aimed to unify all physics by employing the sole concept of energy, without relying on mechanical models. This paper argues that Cassirer's interest in the history of the energy principle and the energetic controversy is entangled with the main themes of his philosophy of physics up to the 1920s: the opposition between the a priori and the a posteriori and the (...) substance-concept and the function-concept. These interwoven motifs are not always easy to disentangle. The paper suggests that Cassirer's interpretation of the energy principle can serve as a guiding thread that runs through Cassirer's philosophy of physics up to the 1920s. (shrink)

This is the third of a series of essays on the development and reception of Wilhelm Ostwald’s energetics. The first essay described the chemical origins of Ostwald’s interest in the energy concept and his motivations for seeking a comprehensive science of energy. The second essay and the present one discuss his various attempts, beginning in 1891 and extending over almost 3 years, to develop a consistent and coherent energetic theory. A final essay will consider reactions to this work and (...) Ostwald’s replies, and will also seek to evaluate his program of research. Ostwald’s project—to reconstruct physics and chemistry “as a pure energetics”—is worth attending to for several reasons: first, because Ostwald did ground-breaking work in chemistry (he was awarded a Nobel Prize in 1909 for his studies in catalysis and rates of reaction); second, because an important school of physical chemistry formed around him at Leipzig, a school that promoted his ideas; and, finally, because he was a prominent and vigorous participant in debates at the end of the nineteenth century concerning the proper course of physical theory.

Esta investigação ilustra como o Interpretante energético de Peirce facilita a conscientização entre os usuários de signos. Peirce caracteriza o Interpretante energético/existencial como “empenho” e “esforço”. Por forçar a atenção e a progressão da ação, o Interpretante energético destaca as relações de signos atomísticos/pontuais de causa e efeito apresentando junções entre os eventos: começo, meio e fim. A Primeiridade e a Terceiridade subjacentes perpetuam ainda mais o componente pontual presente nas relações de ação, operacional quando o esforço produz resistência contra (...) um sentimento/força oposta. O esforço é, no entanto, apenas um lado do Interpretante energético de Peirce; o lado oposto ocorre quando os elementos externos têm um papel mais ativo na destruição de crenças/ações anteriores. Os Interpretantes energéticos podem inibir, ou seja, resultar em atenção a um estímulo, enquanto ignoram outro. No entanto, inibir/resistir conscientemente a uma força introduz o controle além de si mesmo—reflexos do outro sobre os atos conscientes de um agente. Essa influência entre interlocutores satisfaz a máxima de Peirce de um “lugar comum para ficar”, demonstrando compreensão mútua do efeito próprio do signo. De fato, os Interpretantes energéticos podem resultar em um efeito de tal proporção sobre um ou ambos os interlocutores que uma mudança de hábito se materialize. Assim, os Interpretantes energéticos condensam a perfectividade exercida por esforços particulares, sugerindo a probabilidade de seu sucesso discursivo. (shrink)

The use of organic farming technologies has certain advantages in some situations and for certain crops such as maize; however, with other crops such as vegetables and fruits, yields under organic production may be substantially reduced compared with conventional production. In most cases, the use of organic technologies requires higher labor inputs than conventional technologies. Some major advantages of organic production are the conservation of soil and water resources and the effective recycling of livestock wastes when they are available.

: In several works Teresa Brennan examines how, contrary to social notions of the separate and contained self, all that exists in the natural world is connected energetically. She identifies a "foundational fantasy" whereby the ego comes into existence and is maintained by the notion that it controls the mother. The effects of this fantasy are socially oppressive and, in the technological era, environmentally disastrous. My examination of narratives and images in ancient myth, popular culture, literature, and art suggest ways (...) to counteract the destructive fantasy through re-symbolization of the relation to what Brennan understands as the original/living nature, which is correlated to the mother's body.

Psychological studies (Proffitt, 2006) have demonstrated that what one sees is influenced by one's goals, physiological state, and emotions. These studies demonstrate that there is a positive correlation between the physical demands (energetic cost) and perceived valence (emotional cost) of a task and the appearance of slant and egocentric distance in the environment. The studies are compelling. However, one can question whether their results are due to changes in the way participants perceived the orientation and extent of their environment or (...) are instead artifacts of the way they judged the difficulty of expected tasks in particular contexts. We asked participants to sketch the rough spatial layout of several paintings as accurately as possible. In this type of task participants continuously compare what they have drawn against what they perceive. Therefore, participants performance can be interpreted as a means to directly measure of the spatial metric of perception. We chose two paintings by Andrew Wyeth as target images: “Christina's World” and “Winter, 1946.” Participants were asked to draw the spatial arrangement of the key features of the scene depicted in the target painting twice: prior to being presented with biographical information about the subject of the painting condition; and then again after being told the biographical information that altered the perceived task demands or emotional valence of the events they depicted. We predicted that participants' drawings would differ in the two conditions indicating that: change in the energetic or emotional costs of the depicted action would cause them to perceive the depicted orientation of hills as steeper and distance between key landmarks as longer. Results from the energetic cost condition support this prediction. We will discuss our results and the suggestion that these types of effects reflect a role for motor simulation in perception (Witt, 2005). (shrink)

The notions of conservation and relativity lie at the heart of classical mechanics, and were critical to its early development. However, in Newton’s theory of mechanics, these symmetry principles were eclipsed by domain-specific laws. In view of the importance of symmetry principles in elucidating the structure of physical theories, it is natural to ask to what extent conservation and relativity determine the structure of mechanics. In this paper, we address this question by deriving classical mechanics—both nonrelativistic and relativistic—using relativity and (...) conservation as the primary guiding principles. The derivation proceeds in three distinct steps. First, conservation and relativity are used to derive the asymptotically conserved quantities of motion. Second, in order that energy and momentum be continuously conserved, the mechanical system is embedded in a larger energetic framework containing a massless component that is capable of bearing energy. Imposition of conservation and relativity then results, in the nonrelativistic case, in the conservation of mass and in the frame-invariance of massless energy; and, in the relativistic case, in the rules for transforming massless energy and momentum between frames. Third, a force framework for handling continuously interacting particles is established, wherein Newton’s second law is derived on the basis of relativity and a staccato model of motion-change. Finally, in light of the derivation, we elucidate the structure of mechanics by classifying the principles and assumptions that have been employed according to their explanatory role, distinguishing between symmetry principles and other types of principles that are needed to build up the theoretical edifice.

This article is concerned with the ways in which bodies and subjects are enacted and negotiated in the encounter between client and practitioner within specialized kinesiology – a specific complementary and alternative medical practice. In the article we trace the ideas of connections and disconnections, which are conceptualized and practised within kinesiology. We attempt to come to grips with these specific notions of relatedness through the introduction of the concept ‘energetic kinship’ and to relate them to more general discussions about (...) the nature of subjects, bodies and social identity in late modern society. We argue that through the particular approach to the body as a prime locus of knowledge on which kinesiological treatment practices are based, kinesiology offers clients an alternative understanding of being-in-the-world. The understanding of the body as the locus of knowledge might, on the one hand, potentially alleviate the individual from the weight of a late modern focus on self-responsible, rational and autonomous individuality, while, on the other hand, it simultaneously supports this understanding. Hence, we argue that kinesiology operates with a subject which is both inherently related and individual at the same time, and that these particular understandings may be appealing in a world in which health and illness are increasingly seen as a question of individual responsibility. The article was written on the basis of interviews and participant observation among kinesiological teachers and practitioners in Denmark. (shrink)

The article reconstructs and critically discusses the energetic metaphysics of Dimitar Vatsov, which may be regarded as an important event in the philosophical life in Bulgaria. The article consists of two parts. The first part situates Vatsov's project in the context of the contemporary development of metaphysics and presents the evolution and logic of its realization, emphasizing the central ideas of actuality, energy, and codification. The second part presents a series of critical observations on the realization of the project, related (...) to conceptual ambiguities and problematic theoretical moves. It is argued that the modal aspects of energetic metaphysics need conceptual clarification and theoretical justification. The article also aims to provoke a broader discussion on the state and future of metaphysical research in Bulgarian philosophy. (shrink)

This inquiry illustrates how Peirce’s Energetic Interpretant facilitates consciousness-raising between sign users. Because it forces attention and progression of action, the Energetic Interpretant highlights perfective aspectual characteristics, namely atomistic/punctual cause-effect sign relations by featuring junctures between events: beginning, middle, end. For example, the stops and starts of events are influenced by the nature of the action, in addition to the agent’s idiosyncratic preferences and predilections. The Thirdness underlying it further perpetuates the punctual component present in action relations, operational when effort (...) produces resistance against an opposing force. Because effort can materialize physically, or internally, it demonstrates the continued primacy of Peirce’s categories in fostering certain consequences. Energetic Interpretants can inhibit, i.e., attention to one stimulus, while ignoring another. Nonetheless, consciously inhibiting/resisting a force introduces control beyond the self—another’s reflections upon the conscious acts of an agent. This influence between interlocutors satisfies Peirce’s maxim of a “common place to stand”, demonstrating mutual comprehension of the sign’s proper effect. In fact, Energetic Interpretants may result in an effect of such proportion upon either or both interlocutors that a habit-change materializes. As such, Energetic Interpretants epitomize the perfectivity exercised by particular efforts, intimating the likelihood of their discursive success. Inherent in punctual events is the element of surprise, which ultimately hastens the kind of habit-change especially exhibited in Peirce’s double consciousness —self talking to self or other. (shrink)
