Current knowledge of the genetic, epigenetic, behavioural and symbolic systems of inheritance requires a revision and extension of the mid-twentieth-century, gene-based, 'Modern Synthesis' version of Darwinian evolutionary theory. We present the case for this by first outlining the history that led to the neo-Darwinian view of evolution. In the second section we describe and compare different types of inheritance, and in the third discuss the implications of a broad view of heredity for various aspects of evolutionary theory. We end (...) with an examination of the philosophical and conceptual ramifications of evolutionary thinking that incorporates multiple inheritance systems. (shrink)

The autopoietic theory and the enactive approach are two theoretical streams that, in spite of their historical link and conceptual affinities, offer very different views on the nature of living beings. In this paper, we compare these views and evaluate, in an exploratory way, their respective degrees of internal coherence. Focusing the analyses on certain key notions such as autonomy and organizational closure, we argue that while the autopoietic theory manages to elaborate an internally consistent conception of living beings, the (...) enactive approach presents an internal tension regarding its characterization of living beings as intentional systems directed at the environment.

The nature/nurture debate is not dead. Dichotomous views of development still underlie many fundamental debates in the biological and social sciences. Developmental systems theory offers a new conceptual framework with which to resolve such debates. DST views ontogeny as contingent cycles of interaction among a varied set of developmental resources, no one of which controls the process. These factors include DNA, cellular and organismic structure, and social and ecological interactions. DST has excited interest from a wide range of researchers, (...) from molecular biologists to anthropologists, because of its ability to integrate evolutionary theory and other disciplines without falling into traditional oppositions. The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioral development, implications of DST for the philosophy of biology, and critical reactions to DST.

This book addresses universal tendencies of human vowel systems from the point of view of self-organisation. It uses computer simulations to show that the same universal tendencies found in human languages can be reproduced in a population of artificial agents. These agents learn and use vowels with human-like perception and production, using a learning algorithm that is cognitively plausible. The implications of these results for the evolution of language are then explored.

This article presents the first, systematic analysis of the ethical challenges posed by recommender systems through a literature review. The article identifies six areas of concern, and maps them onto a proposed taxonomy of different kinds of ethical impact. The analysis uncovers a gap in the literature: currently user-centred approaches do not consider the interests of a variety of other stakeholders—as opposed to just the receivers of a recommendation—in assessing the ethical impacts of a recommender system.

We locate winning strategies for various ${\mathrm{\Sigma }}_{3}^{0}$ -games in the L-hierarchy in order to prove the following: Theorem 1.

In recent previous work, the authors proposed a new approach extending the framework of statistical mechanics to reparametrization-invariant systems with no additional gauges. In this paper, the approach is generalized to systems defined by more than one Hamiltonian constraint. We show how well-known features as the Ehrenfest–Tolman effect and the Jüttner distribution for the relativistic gas can be consistently recovered from a covariant approach in the multi-fingered framework. Eventually, the crucial role played by the interaction in the definition (...) of a global notion of equilibrium is discussed. (shrink)

How are data science systems made to work? It may seem that whether a system works is a function of its technical design, but it is also accomplished through ongoing forms of discretionary work by many actors. Based on six months of ethnographic fieldwork with a corporate data science team, we describe how actors involved in a corporate project negotiated what work the system should do, how it should work, and how to assess whether it works. These negotiations laid (...) the foundation for how, why, and to what extent the system ultimately worked. We describe three main findings. First, how already-existing technologies are essential reference points to determine how and whether systems work. Second, how the situated resolution of development challenges continually reshapes the understanding of how and whether systems work. Third, how business goals, and especially their negotiated balance with data science imperatives, affect a system’s working. We conclude with takeaways for critical data studies, orienting researchers to focus on the organizational and cultural aspects of data science, the third-party platforms underlying data science systems, and ways to engage with practitioners’ imagination of how systems can and should work.

A classic objection to autonomous weapon systems (AWS) is that these could create so-called responsibility gaps, where it is unclear who should be held responsible in the event that an AWS were to violate some portion of the law of armed conflict (LOAC). However, those who raise this objection generally do so presenting it as a problem for AWS as a whole class of weapons. Yet there exists a rather wide range of systems that can be counted as (...) “autonomous weapon systems”, and so the objection is too broad. In this article I present a taxonomic approach to the objection, examining a number of systems that would count as AWS under the prevalent definitions provided by the United States Department of Defense and the International Committee of the Red Cross, and I show that for virtually all such systems there is a clear locus of responsibility which presents itself as soon as one focuses on specific systems, rather than general notions of AWS. In developing these points, I also suggest a method for dealing with near-future types of AWS which may be thought to create situations where responsibility gaps can still arise. The main purpose of the arguments is, however, not to show that responsibility gaps do not exist or can be closed where they do exist. Rather, it is to highlight that any arguments surrounding AWS must be made with reference to specific weapon platforms imbued with specific abilities, subject to specific limitations, and deployed to specific times and places for specific purposes. More succinctly, the arguments show that we cannot and should not aim to treat AWS as if all of these shared all morally relevant features, but instead on a case-by-case basis. Thus, we must contend with the realities of weapons development and deployment, and tailor our arguments and conclusions to those realities, and with an eye to what facts obtain for particular systems fulfilling particular combat roles.

Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future (...) class='Hi'>systems will need to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent. (shrink)

At the start of the 21st century, Corporate Social Responsibility (CSR) seems to have great potential for innovating business practices with a positive impact on People, Planet and Profit. In this article the differences between the management systems approach of the nineties, and Corporate Social Responsibility are analysed.An analysis is structured around three business principles that are relevant for CSR and management systems: (1) doing things right the first time, (2) doing the right things, and (3) continuous improvement (...) and innovation. Basically CSR is focussing on the second principle, and management systems focus on the first. However, CSR is very likely to build on the management systems as well.From a CSR point of view, the existing generation of management systems with their focus on rational control (= doing things right) can only be of limited use in the development of CSR. However, the preventive rationalities of management systems are important. Values and the principle doing the right things is extremely relevant for CSR. This goes far beyond the present generation of ISO type management systems; opportunities stem from building on TQM approaches like the EFQM Business Excellence model. Continuous improvement and innovation is a permanent challenge underlying the two other business principles, and requires both individual and organisational learning processes. In the present generation of management systems, continuous improvement mainly addresses rational prevention, barely the value aspects of business.For the further development and implementation of CSR, each of the three business management principles are vital. There is a need for a new generation of management systems that addresses the values at stake in strategic decision-making, both at company level and in the behaviour of individuals, while the rationalities of prevention and anticipation are still relevant. In both directions more emphasis for continuous learning and innovation will be needed.CSR is likely to trigger the development of management systems in the directions mentioned. This will support companies to be credible and transparent in improving the performance with respect to people, planet and profit. (shrink)

This study of Western philosophic systems, their types, history, relations, and projected future in the next half century, stems from Robert S. Brumbaugh’s forty-year fascination with the paradox of the many consistent overarching systems of ideas that are nevertheless mutually exclusive. Brumbaugh argues that when we isolate these systems’s patterns and look at them more abstractly, they consistently fall into four main types, and the interaction of these four types of explanation and order is a dominant theme (...) in the history of Western philosophy. In Brumbaugh’s view these four philosophic systems are not, as some critical historians and thinkers have claimed, so different that they are mutually unintelligible, forcing us to make a choice among them that is entirely arbitrary. But neither are they, as a majority of past thinkers and historians have hoped, simply parts of some single "right" or "orthodox" scheme. Their mutual understanding requires a method of transformation that interprets one to another without destroying their diversity. The history of Western philosophy from the fifth century A.D. to the present shows a pattern of alternating revolutions in systematic method and direction of explanation. Brumbaugh feels that the pattern is continuing in a change toward a revised Platonism, just beginning with the twenty-first century. He anticipates that it will be a Platonism of a new texture, one that has matured and learned a great deal in the course of the adventures of its ideas through space and time. (shrink)

The definition of “model of a system” in terms of a homomorphism of the states of the system is evaluated and an alternative definition in terms of sequence generators is proposed. Sequence generators are finite graphs whose points represent complete states of a system. Sequence generators include finite automata and other information processing systems as special cases. It is shown how to define models in terms of a projection operator which applies to any sequence generator which has an output (...) projection and yields a new sequence generator. A model produced by the projection operator is embedded in the system it models. The notion of embedding is discussed informally and some questions raised about the relations of deterministic, indeterministic, and probabilistic models and systems. (shrink)

We study whether changes in analyst recommendation ratings systems encouraged by the implementation of NASD 2711 in 2002 are associated with improved objectivity and independence in analyst recommendations. Using recommendations issued during windows surrounding major investment banking events, we show that reductions in analyst optimism following the reforms concentrate in the recommendations of analysts whose employer adopted a three-tier rating system at the time of the reforms, and that this effect is generally stronger for analysts whom the underlying incentives (...) to engage in unethical behaviour is greatest. We also find evidence that adoption of the three-tier system improved the market’s perception of the objectivity of analyst recommendations issued after SEOs, and that for hold and sell-type recommendations this effect was stronger for analysts subject to the greatest potential ethical conflicts. While we find some evidence of a general post-reform increase in the profitability of recommendations issued following equity transactions, this improvement was only conditioned by changes to the rating system in our IPO sample.

Molecular systems orchestrating the biology of the cell typically involve a complex web of interactions among various components and span a vast range of spatial and temporal scales. Computational methods have advanced our understanding of the behavior of molecular systems by enabling us to test assumptions and hypotheses, explore the effect of different parameters on the outcome, and eventually guide experiments. While several different mathematical and computational methods are developed to study molecular systems at different spatiotemporal scales, (...) there is still a need for methods that bridge the gap between spatially‐detailed and computationally‐efficient approaches. In this review, we summarize the capabilities of agent‐based modeling (ABM) as an emerging molecular systems biology technique that provides researchers with a new tool in exploring the dynamics of molecular systems/pathways in health and disease.

In this chapter, it is argued on two different grounds that sentences in natural languages can be seen as systems. First, beyond their linear order, sentences exhibit a syntactic hierarchical structure. Therefore, they are structured entities. Although this structure is usually interpreted as independent of meaning, many semanticists believe that syntactic structure indicates the order in which the meanings of the parts are combined. Second, although the principle of compositionality—which states that the meaning of a sentence is a function (...) of the meanings of the parts of that sentence—is valid in general for natural languages, this principle has been shown to have many exceptions, where interpretation does not proceed bottom-up but top-down, from the meaning of the whole to the meaning of the parts. For this reason, a radical version of the principle of compositionality is untenable; if the whole depends on its parts and the parts on the whole, then the sentence is a system that cannot be dissected into separate parts without losing something essential.

Due to advances in military technology, there has been an outpouring of research on what are known as autonomous weapon systems (AWS). However, it is common in this literature for arguments to be made without first making clear exactly what definitions one is employing, with the detrimental effect that authors may speak past one another or even miss the targets of their arguments. In this article I examine the U.S. Department of Defense and International Committee of the Red Cross (...) definitions of AWS, showing that these definitions are far broader than some recognize, and that they therefore classify a much larger set of weapons as AWS. I then show that these broader views of AWS have implications for what moral and legal rules we might argue should be applied to such systems. I conclude by arguing there is a greater need for precision and clarity within AWS debates, in order to ensure that researchers are discussing the same weapon systems (autonomous or otherwise) when they argue for or against particular points. The purpose of this article is not to defend any specific view of AWS, nor to further any general endorsement or objection to such systems, but rather to show the importance of argumentative clarity in this debate.

The indexing systems used to systematise our knowledge about a domain tend to have an evaluative character: they represent some things as more important, general, complex, or central than others. They are also imperfect and can misrepresent something as more or less important, etc., than it really is. Such distortions mostly result from mistakes made due to lack of time or resources. In some cases they follow systematic patterns which can reveal the implicit judgements and values shared within a (...) community who maintains and uses an index. I focus on the example of PhilPapers, the largest database of philosophy texts available, to show how the arrangement of categories and the way items are assigned to them, can effectively marginalise certain topics, authors, and entire traditions. I draw attention to such issues as: ordering, size and depth of categories, the use of miscellaneous categories, localising indexes in category names, and assigning items to some but not other categories. I suggest that such structuring of the index can have an impact on users, normalising marginalisation and contributing to the perpetuation of inequalities. I conclude by offering some suggestions for improvement which might help our databases flourish and become even more useful. (shrink)

EU regulations explicitly preclude recirculation aquaculture systems (RAS) for aquaculture grow-out from organic certification because they are not close enough to nature (Regulation (EEC) No. 710/2009). Meanwhile, according to another EU regulation, one criterion for organic food production is its contribution to sustainable development (Regulation (EEC) No. 834/2007). Against this background, one might argue that in spite of their distance to nature RAS are innovative solutions to sustainability issues in food production. The paper will deal with the claim that (...) RAS for aquaculture could be one innovative solution to sustainability issues. In this respect, the picture is ambivalent. In the past, the organic movement (OM) has searched for innovative alternatives to industrial forms of agriculture and food production that are non-sustainable. Hence, the majority of the OM does not feel fit to support industrial RAS, even though one might argue that these systems comply with many of the European OM’s founding principles. While there are potential positive effects for a sustainable development, we might still regard these systems as techno-scientific solutions to social problems. This paper discusses innovation narratives related to RAS from the perspective of post-normal innovation critique. It first presents potential contribution to a more sustainable food sector. It then contrasts these arguments within critical assessments of innovation narratives for sustainable development. Finally, the paper concludes by discussing moral challenges of RAS for the OM’s self-conception. (shrink)

The education systems can be analysed by using the distinction along different types of welfare regimes. Esping-Andersen (1990) described the Scandinavian universalistic, Continental corporatist, and Anglo-Saxon liberal models. The purpose of the paper is a comparative analysis of the development of educational systems in the Baltic states. We used the PISA 2012 survey data and compared the Baltic countries with three “old” EU member states: UK representing the Anglo-Saxon liberal model, Germany for the Continental corporatist model and Finland (...) as an example of the Scandina­vian model. PISA 2003, 2006 and 2009 data were used for a retrospective analysis of countries’ performance. We considered four aspects of the organization of the national school systems: human and material resources in schools, leadership and the level of school autonomy, assessment, school selectivity and ability grouping. We found that three Baltic states do not represent a single Central and Eastern European model. (shrink)

Evolutionary systems biology (ESB) aims to integrate methods from systems biology and evolutionary biology to go beyond the current limitations in both fields. This article clarifies some conceptual difficulties of this integration project, and shows how they can be overcome. The main challenge we consider involves the integration of evolutionary biology with developmental dynamics, illustrated with two examples. First, we examine historical tensions between efforts to define general evolutionary principles and articulation of detailed mechanistic explanations of specific traits. (...) Next, these tensions are further clarified by considering a recent case from another field focused on developmental dynamics: stem cell biology. In the stem cell case, incompatible explanatory aims block integration. Experimental approaches aim at mechanistic explanation while dynamical system models offer explanation in terms of general principles. We then discuss an ESB case in which integration succeeds: search for general attractors using a dynamical systems framework synergizes with the experimental search for detailed mechanisms. Contrasts between the positive and negative cases suggest general lessons for achieving an integrated understanding of developmental and evolutionary dynamics. The key integrative move is to acknowledge two complementary aims, both relevant to explanation: identifying the space of possible dynamic states and trajectories, and mechanistic understanding of causal interactions underlying a specific phenomenon of interest. These two aims can support one another in a joint project characterizing dynamic aspects of evolving lineages. This more inclusive project can lead to insights that cannot be reached by either approach in isolation. (shrink)

Defining a composition operation on sets of formulas one obtains a many-sorted algebra which satisfies the superassociative law and one more identity. This algebra is called the clone of formulas of the given type. The interpretations of formulas on an algebraic system of the same type form a many-sorted algebra with similar properties. The satisfaction of a formula by an algebraic system defines a Galois connection between classes of algebraic systems of the same type and collections of formulas. Hypersubstitutions (...) are mappings sending pairs of operation symbols to pairs of terms of the corresponding arities and relation symbols to formulas of the same arities. Using hypersubstitutions we define hyperformulas. Satisfaction of a hyperformula by an algebraic system defines a second Galois connection between classes of algebraic systems of the same type and collections of formulas. A class of algebraic systems is said to be solid if every formula which is satisfied is also satisfied as a hyperformula. On the basis of these two Galois connections we construct a conjugate pair of additive closure operators and are able to characterize solid classes of algebraic systems. (shrink)

The agricultural lands established by emirs, caliphs, and high-ranking officials in al-Andalmade significant contributions to the development of agriculture. These areas essentially served as research and experimentation centers, where new plant species were tested, and different seeds and plants were cultivated. Through these areas, trials of new species brought from different regions were conducted, and their production was subsequently expanded. With the attention and support given to agriculture in al-Andalus, irrigation systems also advanced, leading to an increase in crop (...) variety, improved product quality, and enhanced productivity. The use of new agricultural techniques was another key characteristic of the period. The development of irrigation techniques and the expansion of irrigated farming became defining features of this era. What were the most important techniques used by the Muslims during this period? Did the Muslims in al-Andalus establish a typical and just legal framework for the equitable distri-bution of water resources and the resolution of disputes surrounding them? Who were the prominent scholars in the field of agriculture and irrigation in al-Andalus, and what legacy and works did they leave behind? This article seeks to answer these and similar questions, addressing the functionality of agricultural and irrigation policies in al-Andalus. (shrink)

Developmental Systems Theory (DST) emphasises the importance of non-genetic factors in development and their relevance to evolution. A common, deflationary reaction is that it has long been appreciated that non-genetic factors are causally indispensable. This paper argues that DST can be reformulated to make a more substantive claim: that the special role played by genes is also played by some (but not all) non-genetic resources. That special role is to transmit inherited representations, in the sense of Shea (2007: Biology (...) and Philosophy, 22, 313-331). Formulating DST as the claim that there are non-genetic inherited representations turns it into a striking, empirically-testable hypothesis, driving the sort of investigations that are only now beginning to appear in the scientific literature. DST’s characteristic rejection of a gene vs. environment dichotomy is preserved, but without dissolving all potentially explanatory distinctions into an interactionist causal soup, as some have alleged.

Context is an important construct in many domains of cognition, including learning, memory, and emotion. We used dynamical systems methods to demonstrate the episodic nature of experience by showing a natural separation between the scales over which within-context and between-context relationships operate. To do this, we represented an individual's emails extending over about 5 years in a high-dimensional semantic space and computed the dimensionalities of the subspaces occupied by these emails. Personal discourse has a two-scaled geometry with smaller within-context (...) dimensionalities than between-context dimensionalities. Prior studies have shown that reading experience and visual experience have a similar two-scaled structure. Furthermore, the recurrence plot of the emails revealed that experience is predictable and hierarchical, supporting the constructs of some influential theories of memory. The results demonstrate that experience is not scale-free and provide an important target for accounts of how experience shapes cognition. (shrink)

One relatively neglected challenge in ethical artificial intelligence (AI) design is ensuring that AI systems invite a degree of emotional and moral concern appropriate to their moral standing. Although experts generally agree that current AI chatbots are not sentient to any meaningful degree, these systems can already provoke substantial attachment and sometimes intense emotional responses in users. Furthermore, rapid advances in AI technology could soon create AIs of plausibly debatable sentience and moral standing, at least by some relevant (...) definitions. Morally confusing AI systems create unfortunate ethical dilemmas for the owners and users of those systems, since it is unclear how those systems ethically should be treated. I argue here that, to the extent possible, we should avoid creating AI systems whose sentience or moral standing is unclear and that AI systems should be designed so as to invite appropriate emotional responses in ordinary users.

The article analyzes the possibilities and limitations of artificial intelligence. The article considers the subjectivity of artificial intelligence, determines its necessity for solving intellectual problems depending on the possibility of representing the real world as a deterministic system. Methodological limitations of artificial intelligence, which is based on the use of big data technologies, are stated. These limitations cause the impossibility of forming a holistic representation of the objects of cognition and the world as a whole. As a tool for deterministic (...) description of the universe it is proposed to use empirical-metaphysical general theory of systems, which is an extension of existing general theories of systems due to ontological justification of the phenomenon of isomorphism and definition of a limited set of laws, rules, patterns and primitives of forms and relations of objects in the universe. The distinction of natural (human) and artificial intelligence is considered, including the realization of multisystem integration of intelligence in physical, biological, social and spiritual systems. A philosophically grounded approach to ensuring the evolutionary properties of artificial intelligence is formulated, based on the inclusion of non-equilibrium mechanisms through which stability is realized.

From birth to 15 months infants and caregivers form a fundamentally intersubjective, dyadic unit within which the infant’s ability to recognize gender/sex in the world develops. Between about 18 and 36 months the infant accumulates an increasingly clear and subjective sense of self as female or male. We know little about how the precursors to gender/sex identity form during the intersubjective period, nor how they transform into an independent sense of self by 3 years of age. In this Theory and (...) Hypothesis article I offer a general framework for thinking about this problem. I propose that through repetition and patterning, the dyadic interactions in which infants and caregivers engage imbue the infant with an embodied, i.e., sensori-motor understanding of gender/sex. During this developmental period (which I label Phase 1) gender/sex is primarily an intersubjective project. From 15 to 18 months (which I label Phase 2) there are few reports of newly appearing gender/sex behavioral differences, and I hypothesize that this absence reflects a period of developmental instability during which there is a transition from gender/sex as primarily inter-subjective to gender/sex as primarily subjective. Beginning at 18 months (i.e., the start of Phase 3), a toddler’s subjective sense of self as having a gender/sex emerges, and it solidifies by 3 years of age. I propose a dynamic systems perspective to track how infants first assimilate gender/sex information during the intersubjective period (birth to 15 months); then explore what changes might occur during a hypothesized phase transition (15 to 18 months), and finally, review the emergence and initial stabilization of individual subjectivity-the period from 18 to 36 months. The critical questions explored focus on how to model and translate data from very different experimental disciplines, especially neuroscience, physiology, developmental psychology and cognitive development. I close by proposing the formation of a research consortium on gender/sex development during the first 3 years after birth. (shrink)

If someone assaults you, should they get a milder penalty if they are rich than if they are poor? We wouldn't dream of passing a law that formalized such an arrangement. But the design of our legal systems in the US, UK, and elsewhere, which permits people with sufficient money to pay for better lawyers, means that wealth often does make a difference to legal outcomes. Justice, then, depends not only on the substance of the laws we pass, but (...) on the design of the system that administers and enforces them. Philosophers and legal theorists, however, have paid relatively little attention to what justice demands of the general design and structure of the legal system. Equal Justice argues among other things that market principles should not determine access to legal resources. If, for example, a large corporation sues a small startup, either the corporation has to use a law firm of the quality that the startup can afford or--which would be preferable, given the corporation's in-house lawyers--the startup would be given a subsidy to afford a top firm. The author builds on this core idea of equal access to resources to work out how the court system and the legal profession should be structured in order to ensure a generally just legal system.

This research was designed to understand better the patterns of agricultural intensification and transformation occurring in Africa south of the Sahara using the Ghanaian case. The paper examines changes in farming systems and the role of various endogenous and exogenous factors in driving the conversion of arable lands to agricultural uses in four villages within two agro-ecologically distinct zones of Ghana: the Guinea Savannah and Transition zones. Using historical narratives and land-cover maps supplemented with quantitative data at regional levels, (...) the research shows that farming has intensified in the villages, as farmers increased their farm size in response to factors such as population growth, market access, and changing rural lifestyle. The overall trend suggests a gradual move toward intensification through increasing use of labor-saving technologies rather than land-saving inputs—a pattern that contrasts with Asia’s path to its Green Revolution. The findings in this paper provide evidence of the dynamism occurring in African farming systems; hence, they point toward a departure from stagnation narratives that have come to prevail in the debate on agricultural transformation and intensification in Africa south of the Sahara. We conclude that it is essential for future research to expand the scope of this work, while policies should focus on lessons learned from these historical processes of genuine change and adaptation.

Both natural and engineered systems are fundamentally dynamical in nature: their defining properties are causal, and their functional capacities are causally grounded. Among dynamical systems, an interesting and important sub-class are those that are autonomous, anticipative and adaptive (AAA). Living systems, intelligent systems, sophisticated robots and social systems belong to this class, and the use of these terms has recently spread rapidly through the scientific literature. Central to understanding these dynamical systems is their complicated (...) organisation and their consequent capacities for re- and self- organisation. But there is at present no general analysis of these capacities or of the requisite organisation involved. We define what distinguishes AAA systems from other kinds of systems by characterising their central properties in a dynamically interpreted information theory. (shrink)
