We describe an approach to measuring biological information where ‘information’ is understood in the sense found in Francis Crick’s foundational contributions to molecular biology. Genes contain information in this sense, but so do epigenetic factors, as many biologists have recognized. The term ‘epigenetic’ is ambiguous, and we introduce a distinction between epigenetic and exogenetic inheritance to clarify one aspect of this ambiguity. These three heredity systems play complementary roles in supplying information for development. -/- We then consider the (...) evolutionary significance of the three inheritance systems. Whilst the genetic inheritance system was the key innovation in the evolution of heredity, in modern organisms the three systems each play important and complementary roles in heredity and evolution. -/- Our focus in the earlier part of the paper is on ‘proximate biology’, where information is a substantial causal factor that causes organisms to develop and causes offspring to resemble their parents. But much philosophical work has focused on information in ‘ultimate biology’. Ultimate information is a way of talking about the evolutionary design of the mechanisms of development and inheritance. We conclude by clarifying the relationship between the two. Ultimate information is not a causal factor that acts in development or heredity, but it can help to explain the evolution of proximate information, which is. (shrink)

In their considered reviews both Thomas Pradeu and Lindell Bromham introduce important topics not sufficiently covered in our book. Pradeu asks us to enlarge on the epigenetic and ecological context of genes, particularly in the form of symbioses. We use the relationship between eukaryotes and their symbiotic organisms as a welcome opportunity to clarify our concept of the developmental niche, and its relationship to the developmental system. Bromham’s comments reveal that she is primarily interested in identifying macroevolutionary patterns. From her (...) vantage point eco-evo-devo, the study of phenotypic plasticity, epigenetic and exogenetic inheritance, have not yet demonstrated the need for any revolutionary change in evolutionary thought. For us they highlight the extent to which proximate developmental mechanisms can inform ultimate biology. (shrink)

Everyone has heard of ‘epigenetics’, but the term means different things to different researchers. Four important contemporary meanings are outlined in this paper. Epigenetics in its various senses has implications for development, heredity, and evolution, and also for medicine. Concerning development, it cements the vision of a reactive genome strongly coupled to its environment. Concerning heredity, both narrowly epigenetic and broader ‘exogenetic’ systems of inheritance play important roles in the construction of phenotypes. A thoroughly epigenetic model of development (...) and evolution was Waddington’s aim when he introduced the term ‘epigenetics’ in the 1940s, but it has taken the modern development of molecular epigenetics to realize this aim. In the final sections of the paper we briefly outline some further implications of epigenetics for medicine and for the nature/nurture debate. (shrink)

Despite great advances in understanding genetic mechanisms, there still exists a bias toward equating genes with innate modules that determine important developmental events. But genes are equally relevant to understanding developmental plasticity shaped by ecological events. In other words, the term 'genetic inheritance' does not specify ontogenetic mechanisms. Here we present a case history of a species assumed to be under the control of prespecified genetic wiring to direct critical behavioral events such as communication and mating. We show, however, (...) that exogenetic processes stemming from the species's ontogenetic niche provide an alternative view of the flexibility of development especially with respect to behavioral performance.

The idea that development is the expression of information accumulated during evolution and that heredity is the transmission of this information is surprisingly hard to cash out in strict, scientific terms. This paper seeks to do so using the sense of information introduced by Francis Crick in his sequence hypothesis and central dogma of molecular biology. It focuses on Crick's idea of precise determination. This is analysed using an information-theoretic measure of causal specificity. This allows us to reconstruct some of (...) Crick's claims about information in transcription and translation. Crick's approach to information has natural extensions to non-coding regions of DNA, to epigenetic marks, and to the genetic or environmental upstream causes of those epigenetic marks. Epigenetic information cannot be reduced to genetic information. The existence of biological information in epigenetic and exogenetic factors is relevant to evolution as well as to development.

Fifteen families cooperated in this study. Each consisted of father, mother and two or more children over 14 years of age. The recording of potentials was made by means of standard amplifiers and a Westinghouse oscillograph. An analysis of the records leads the author to conclude that, while no data which indicate a certain relationship between any members of a family on the basis of their electro-encephalographic patterns can be offered, it is justifiable to assume that the resemblances in the (...) patterns, if any exist, are not marked. The problem of whether or not patterns in brain potentials are inherited is not a closed one. Davis' work would definitely indicate that a hereditary factor does exist. Investigations of possible relationships between grandparents and grandchildren are indicated. (PsycINFO Database Record (c) 2016 APA, all rights reserved). (shrink)

In recent years discussions centered around digital inheritance have increased among social media users and across blockchain ecosystems. As a result digital assets such as social media content cryptocurrencies and non-fungible tokens have become increasingly valuable and widespread, leading to the need for clear and secure mechanisms for transferring these assets upon the testators death or incapacitation. This study proposes a framework for digital inheritance using soulbound tokens and the social recovery pallet as a use case in the (...) Polkadot and Kusama blockchain networks. The findings discussed within this study suggest that while soulbound tokens and the social recovery pallet offer a promising solution for creating a digital inheritance plan the findings also raise important considerations for testators digital executors and developers. While further research is needed to fully understand the potential impacts and risks of other technologies such as artificial intelligence and quantum computing this study provides a primer for users to begin planning a digital inheritance strategy and for developers to develop a more intuitive solution.

Discussion of a metaphysical sense of 'inheritance' and cognate notions relevant to fundamentality.

Niche construction theory (NCT) is distinctive for being explicit in recognizing environmental modification by organisms—niche construction—and its legacy—ecological inheritance—to be evolutionary processes in their own right. Humans are widely regarded as champion niche constructors, largely as a direct result of our capacity for the cultural transmission of knowledge and its expression in human behavior, engineering, and technology. This raises the question of how human ecological inheritance relates to human cultural inheritance. If NCT is to provide a conceptual (...) framework for the human sciences, then it is important that the relationship between these two legacies is clear. We suggest that cultural processes and cultural inheritance can be viewed as the primary means by which humans engage in the universal process of niche construction. (shrink)

In most cultures, extramarital sex is highly restricted for women. In most of those cultures, men transfer wealth to their own sons. In some cultures extramarital sex is not highly restricted for women, and in most of those cultures, men transfer wealth to their sisters' sons. Inheritance to sisters' sons ensures a man's biological relatedness to his heirs, and matrilineal inheritance has been posited as a male accommodation to cuckoldry—a paternity strategy—at least since the 15th century. However, longitudinal (...) analysis of the cumulative effect of female extramarital sex indicates that matrilineal inheritance is most advantageous for women and would be more accurately considered a grandmaternity strategy. That is, if the probability that men's putative children are their biological children is less than 1, the probabilistic degree of relatedness between a female and her matrilineal heirs is higher than her corresponding relatedness to her patrilineal heirs. The same holds true for men only if ρ is very low. The upshot is that for moderate levels of female extramarital sex, matrilineal inheritance, relative to patrilineal inheritance, is highly advantageous for women and disadvantageous for men. Consideration of female variance in reproductive success beyond the first generation, and of a man's network of obligation to the inclusive fitness of his relatives, suggests that although the establishment of matrilineal inheritance may require extremely high levels of female extramarital sex, once established, it is likely to be maintained at levels of ρ that reasonably characterize many societies in the ethnographic record. New analysis of previously published data shows a strong association between matrilineal inheritance and moderate to low probability of paternity, and an even stronger relationship between patrilineal inheritance and high probability of paternity.

Organisms inherit various kinds of developmental information and cues from their parents. The study of inheritance systems is aimed at identifying and classifying the various mechanisms and processes of heredity, the types of hereditary information that is passed on by each, the functional interaction between the different systems, and the evolutionary consequences of these properties. We present the discussion of inheritance systems in the context of several debates. First, between proponents of monism about heredity (gene-centric views), holism about (...) heredity (Developmental Systems Theory), and those stressing the role of multiple systems of inheritance. Second, between those analyzing inheritance solely in terms of replication and transmission, and views that stress the multi-generation reproduction of phenotypic traits. A third debate is concerned with different criteria that have been proposed for identifying and delimiting inheritance systems. A fourth controversy revolves around the significance of the “Lamarckian” aspects of some of the inheritance systems that have been identified, such as epigenetic inheritance and behavioral inheritance, that allow the transmission of environmentally induced characters (i.e., “soft inheritance”).

Recent theoretical work has identified a tightly-constrained sense in which genes carry representational content. Representational properties of the genome are founded in the transmission of DNA over phylogenetic time and its role in natural selection. However, genetic representation is not just relevant to questions of selection and evolution. This paper goes beyond existing treatments and argues for the heterodox view that information generated by a process of selection over phylogenetic time can be read in ontogenetic time, in the course of (...) individual development. Recent results in evolutionary biology, drawn both from modelling work, and from experimental and observational data, support a role for genetic representation in explaining individual ontogeny: both genetic representations and environmental information are read by the mechanisms of development, in an individual, so as to lead to adaptive phenotypes. Furthermore, in some cases there appears to have been selection between individuals that rely to different degrees on the two sources of information. Thus, the theory of representation in inheritance systems like the genome is much more than just a coherent reconstruction of information talk in biology. Genetic representation is a property with considerable explanatory utility. (shrink)

Since the discovery of the double helical structure of DNA, the standard account of the inheritance of features has been in terms of DNA-copying and DNA-transmission. This theory is just a version of the old theory according to which the inheritance of features is explained by the transfer at conception of some developmentally privileged material from parents to offspring. This paper does the following things: (1) it explains what the inheritance of features is; (2) it explains how (...) the DNA-centric theory emerged; (3) it clarifies the relation between the DNA-centric theory and the ‘unfolding’ theory of development; (4) it argues that (given what we now know about developmental processes and genetic activity) the DNA-centric theory should be abandoned in favour of a pluralistic (but not holistic) theory of the inheritance of features. According to this pluralistic theory, the reliable reoccurrence of phenotypes must be explained by appealing not only to processes responsible for the reliable reoccurrence of genetic developmental factors but also to processes responsible for the reliable reoccurrence (or persistence) of nongenetic developmental factors.

The prominent philosopher Feng Youlan in the late 1950s devised an 'abstract inheritance method' with which he sought to salvage traditional thought. The debates over this method and what it entailed lasted until the Cultural Revolution. This book is an examination of those debates, and therepercussions arising from them in the discussions on classical Chinese philosophy.

Inheritance is both an unsettled and structuring concept of contemporary life. This paper argues that inheritance is an analytic through which difference comes to matter. Following Casarino’s (2002) discussion of ‘last’ and ‘other’ limits, I show that inheritance both serves as a mechanism through which difference is captured and domesticated into systems of technoscience and law, and that it evidences the inability of these systems to capture fully its alterity. Taking a wide-ranging and interdisciplinary approach, the paper (...) develops an analytic that explores and expands biosocial understandings of inheritance through two ‘limit cases’: first, the search for and reclamation of inheritance dispossessed in the Transatlantic trade in enslaved people; second, questions of queer reproduction and inheritance. The paper concludes by offering an analytic of inheritance not simply as a force of difference but also as a way of orienting political and ethical thought in the Anthropocene. (shrink)

We defend Jaegwon Kim’s ‘causal inheritance’ principle from an objection raised by Jurgen Schröder. The objection is that the principle is inconsistent with a view about mental properties assumed by Kim, namely, that they are second-order properties. We argue that Schröder misconstrues the notion of second-order property. We distinguish three notions of second-order property and highlight their problems and virtues. Finally, we examine the consequence of Kim’s principle and discuss the issue of whether Kim’s ‘supervenience argument’ generalizes to all (...) special sciences or not. (shrink)

Inheritance is the principle that deontic `ought' is closed under entailment. This paper is about a tension that arises in connection with Inheritance. More specifically, it is about two observations that pull in opposite directions. One of them raises questions about the validity of Inheritance, while the other appears to provide strong support for it. We argue that existing approaches to deontic modals fail to provide us with an adequate resolution of this tension. In response, we develop (...) a positive analysis, and show that this proposal provides a satisfying account of our intuitions. (shrink)

This article addresses the question of whether present day individuals can inherit rights to compensation from their ancestors. It argues that contemporary writing on compensatory justice in general, and on the inheritability of rights to compensation in particular, has mischaracterized what is at stake in contexts where those responsible for wrongdoing continually refuse to make reparation for their unjust actions, and has subsequently misunderstood how later generations can advance claims rooted in the past mistreatment of their forebears. In particular, a (...) full consideration of the wrongful character of non-rectification needs to take account of the multiplicity of temporal points at which compensation could have been, but was not, paid, each with potentially significant consequences for the victims of injustice. This has relevance for what is owed to those who have been wrongfully denied compensation for wrongs that caused them direct harm, and can be extended to others, such as their direct heirs, who are likewise affected by non-rectification. This opens the door to the endorsement of potentially extensive contemporary claims on behalf of the heirs of victims of wrongdoing. (shrink)

Isabelle Stengers’ cosmopolitical proposal is an influential attempt by a European philosopher to transform the burdensome legacy of Western thought. Reconsidering her comprehensive engagement with the cosmology of the British mathematician and philosopher Alfred North Whitehead, this article reveals two concepts as foundational to Stengers’ cosmopolitics: civilization and commerce. While not usually associated with a critical political theory, in her development of what we call a commercial political ontology, Stengers explores the modes of inheriting these ostracized notions. By tracing the (...) genealogy of this political ontology back to Pericles’ first explicit defense of persuasion as a requisite for civilization, we argue that Pericles’ famous funeral oration provides the structure for Whitehead’s cosmology, and, ultimately, Stengers’ cosmopolitics. As such, we understand her cosmopolitical proposal as a dress rehearsal of a funeral eulogy for bourgeois society. (shrink)

What might it mean to think of philosophy as being in the condition of modernism -- in which its relation to its own past, and hence its sense of its own future, has become an undismissable problem?

Through detailed re-readings of these authors' most influential texts, as attentive to their specificity as to their family resemblances, Stephen Mulhall reorients our sense of the philosophical work each text aims to accomplish, to engender a critical dialogue betweeen them from which the elements of a new conception of philosophy might emerge, and to uncover that conception's indebtedness to certain fundamental theological preoccupations.

The paper outlines the contours of an organizational perspective on extended inheritance. Based on theoretical studies about biological organization and extended physiology, this perspective allows for the conception of extended biological legacies while keeping a theoretically indispensable distinction between biological systems and their environment. In this context, the line of demarcation between these systems and their surroundings is modelled on an organizational criterion and on the related conceptual distinction between organizational constraints, whose specific role is to harness flows of (...) matter and energy across generations of composite biological systems, and resources exploited by those systems. Biological legacies are restricted to persisting constitutive elements responsible for the reoccurrence of organizational constraints in a given environment. The case of symbiotic transmission is presented as a paradigmatic system illustrating the main proposed conceptual clarifications. (shrink)

A critical reflection on John Woods's new monograph, Truth in Fiction – Rethinking its Logic. I focus in particular on Woods’s world-inheritance thesis (what others have variously called ‘background,’ ‘the principle of minimal departure,’ and ‘the reality assumption,’ and which replaces Woods’s earlier ‘fill-conditions’) and its interplay with auctorial say-so, arguing that world-inheritance actually constrains auctorial say-so in ways Woods has not anticipated.

Daniel Halliday examines the morality of the right to bequeath or transfer wealth, and argues that inheritance is unjust to the extent that it enhances the intergenerational replication of inequality, concentrating opportunities in certain groups.

It is a fact that human subjects rate sentences about typical properties such as “Ravens are black” as very likely to be true. In comparison, modified sentences such as “Feathered ravens are black” receive lower ratings, especially if the modifier is atypical for the noun, as in “Jungle ravens are black”. This is called themodifier effect. However, the likelihood of the unmodified statement influences the perceived likelihood of the modified statement: the higher the rated likelihood of the unmodified sentence, the (...) higher the rated likelihood of the modified one. That means the modifier effect does not fully blockdefault inheritanceof typical properties from nouns to modified nouns. This paper discusses this inheritance effect. In particular, I ask whether it is the direct result of composing concepts from nouns, that is, a bias toward “black” when processing “raven”. I report a series of experiments in which I find no evidence for a direct inheritance from composition. This supports the view that default inheritance is rather an inference than a bias. (shrink)

This article examines how people of color can biologically inherit the deleterious effects of white racism. Drawing primarily on the field of epigenetics, I demonstrate how transgenerational racial disparities are in fact racist disparities that can be manifest physiologically, helping constitute the chemicals, hormones, cells, and fibers of the human body. Epigenetics can be used to demonstrate how white racism can have durable effects on the biological constitution of human beings that are not limited to the specific person who is (...) the target of white racism, but instead extend to that person's offspring. In this way, the field of epigenetics can help philosophers and others understand the transgenerational biological impact of social forces such as white racism. It reveals that the damage done by white racism is more extensive than critical philosophers of race might have realized, and also that interventions against white racism must address not just the economic, geographical, social, and psychological, but also the biological aspects of human existence. In particular, the article examines racist disparities in preterm birth rates and argues that the scope and significance of prenatal care for African American women must be expanded intergenerationally and include wide-scale forms of racial justice.

The semantic concept of information is one of the most important, and one of the most problematical concepts in biology. I suggest a broad definition of biological information: a source becomes an informational input when an interpreting receiver can react to the form of the source (and variations in this form) in a functional manner. The definition accommodates information stemming from environmental cues as well as from evolved signals, and calls for a comparison between information‐transmission in different types of (...) class='Hi'>inheritance systems—the genetic, the epigenetic, the behavioral, and the cultural‐symbolic. This comparative perspective highlights the different ways in which information is acquired and transmitted, and the role that such information plays in heredity and evolution. Focusing on the special properties of the transfer of information, which are very different from those associated with the transfer of materials or energy, also helps to uncover interesting evolutionary effects and suggests better explanations for some aspects of the evolution of communication.

Supersubstantivalism, the view that material objects are identical to their locations, has recently been defended in metaphysics and philosophy of physics. One of the most powerful arguments in its favour is the so-called argument from harmony. There is a certain harmony between material objects and their locations. Necessarily, if material object x is located at a spherical region, x is spherical. Necessarily, if material object x is located at region r, any part of x is located at a part of (...) r. Supersubstantivalism offers a straightforward explanation of such harmony. By contrast, dualism, the view that material objects are distinct from their locations, does not offer any explanation and should regard harmony principles as unexplained coincidences. In this paper I put forward a theory, which I shall call the ‘Inheritance Theory’, that does provide a straightforward explanation of harmony on behalf of dualists. (shrink)

Generalized Darwinism models cultural development as an evolutionary process, where traits evolve through variation, selection, and inheritance. Inheritance describes either a discrete unit’s transmission or a mixing of traits. In this article, we compare classical models of cultural evolution and generalized population dynamics with respect to blending inheritance. We identify problems of these models and introduce our model, which combines relevant features of both. Blending is implemented as success-based social learning, which can be shown to be an (...) optimal strategy. (shrink)

Heritable traits are predominantly encoded within genomic DNA, but it is now appreciated that epigenetic information is also inherited through DNA methylation, histone modifications, and small RNAs. Several examples of transgenerational epigenetic inheritance of traits have been documented in plants and animals. These include even the inheritance of traits acquired through the soma during the life of an organism, implicating the transfer of epigenetic information via the germline to the next generation. Small RNAs appear to play a significant (...) role in carrying epigenetic information across generations. This review focuses on how epigenetic information in the form of small RNAs is transmitted from the germline to the embryos through the gametes. We also consider how inherited epigenetic information is maintained across generations in a small RNA‐dependent and independent manner. Finally, we discuss how epigenetic traits acquired from the soma can be inherited through small RNAs. (shrink)

This essay seeks to establish the sense in which Derrida’s stated indifference to questions of legitimate descent can function as an ethical or political principle, as he argues in “Marx and Sons.” We track Derrida’s response to accusations of a lack of fealty in texts such as “Marx and Sons,” “Biodegradables: Seven Diary Fragments,” and “Limited Inc a b c … ” alongside his problematization of a certain sense of inheritance or heritage. We argue that Derrida reveals the necessity (...) of troubling established legitimate inheritances as an ethical and political first principle. As such, we argue that Derrida’s reading of Marx is not just one faithful reading among others, but an indifference to the paradigm of fealty in inheritance. (shrink)

The article proposes to further develop the ideas of the Extended Evolutionary Synthesis by including into evolutionary research an analysis of phenomena that occur above the organismal level. We demonstrate that the current Extended Synthesis is focused more on individual traits (genetically or non-genetically inherited) and less on community system traits (synergetic/organizational traits) that characterize transgenerational biological, ecological, social, and cultural systems. In this regard, we will consider various communities that are made up of interacting populations, and for which the (...) individual members can belong to the same or to different species. Examples of communities include biofilms, ant colonies, symbiotic associations resulting in holobiont formation, and human societies. The proposed model of evolution at the level of communities revises classic theorizing on the major transitions in evolution by analyzing the interplay between community/social traits and individual traits, and how this brings forth ideas of top-down regulations of bottom-up evolutionary processes (collaboration of downward and upward causation). The work demonstrates that such interplay also includes reticulate interactions and reticulate causation. In this regard, we exemplify how community systems provide various non-genetic ‘scaffoldings’, ‘constraints’, and ‘affordances’ for individual and sociocultural evolutionary development. Such research complements prevailing models that focus on the vertical transmission of heritable information, from parent to offspring, with research that instead focusses on horizontal, oblique and even reverse information transmission, going from offspring to parent. We call this reversed information transfer the ‘offspring effect’ to contrast it from the ‘parental effect’. We argue that the proposed approach to inheritance is effective for modelling cumulative and distributed developmental process and for explaining the biological origins and evolution of language.

That there is a heritable or familial component of susceptibility to chronic non‐communicable diseases such as type 2 diabetes, obesity and cardiovascular disease is well established, but there is increasing evidence that some elements of such heritability are transmitted non‐genomically and that the processes whereby environmental influences act during early development to shape disease risk in later life can have effects beyond a single generation. Such heritability may operate through epigenetic mechanisms involving regulation of either imprinted or non‐imprinted genes but (...) also through broader mechanisms related to parental physiology or behaviour. We review evidence and potential mechanisms for non‐genomic transgenerational inheritance of ‘lifestyle’ disease and propose that the ‘developmental origins of disease’ phenomenon is a maladaptive consequence of an ancestral mechanism of developmental plasticity that may have had adaptive value in the evolution of generalist species such as Homo sapiens.

Inherited wealth will be of increasing importance in years to come. Yet inheritance taxation is unpopular, and part of this unpopularity is due to family concerns. Such taxation is seen by many as morally problematic because it is taken to violate important family values. In this article, we explore five family arguments against inheritance taxation: firstly, whether we have a right to benefit our children; secondly, whether it is a virtue to benefit one's children; thirdly, whether children have (...) a right to their parent's belongings, due to common ownership; fourthly, whether inheritance taxation may impair a vital sense of continuity and belonging; and lastly, an argument from incentives that appeals specifically to the relation between parents and children. We conclude that none of the arguments provide strong objections against a moderate or even a high inheritance tax rate, at least not when special provisions are made for things like family houses or farms. However, since the arguments all introduce concerns that should be assigned some weight, it would be unjust to abolish inheritance entirely. (shrink)

Inheritance diagrams are directed acyclic graphs with two types of connections between nodes: x → y and x ↛ y . Given a diagram D, one can ask the formal question of “is there a valid path between node x and node y?” Depending on the existence of a valid path we can answer the question “x is a y” or “x is not a y”. The answer to the above question is determined through a complex inductive algorithm on (...) paths between arbitrary pairs of points in the graph. This paper aims to simplify and interpret such diagrams and their algorithms. We approach the area on two fronts. Suggest reactive arrows to simplify the algorithms for the winning paths. We give a conceptual analysis of inheritance diagrams, and compare our analysis to the “small” and “big sets” of preferential and related reasoning. In our analysis, we consider nodes as information sources and truth values, direct links as information, and valid paths as information channels and comparisons of truth values. This results in an upward chaining, split validity, off-path preclusion inheritance formalism of a particularly simple type. We show that the small and big sets of preferential reasoning have to be relativized if we want them to conform to inheritance theory, resulting in a more cautious approach, perhaps closer to actual human reasoning. We will also interpret inheritance diagrams as theories of prototypical reasoning, based on two distances: set difference, and information difference. We will see that some of the major distinctions between inheritance formalisms are consequences of deeper and more general problems of treating conflicting information. It is easily seen that inheritance diagrams can also be analysed in terms of reactive diagrams - as can all argumentation systems. AMS Classification: 68T27, 68T30. (shrink)

In most computational ontologies, information inheritance is based on the taxonomic relation is_a. A given type inherits from other type only if the latter subsumes the former. We assume, however, that inheritance can be related, not only to the taxonomic relation, but also to the meronymic relationship between parts and wholes. The main aim of this paper is to organise upper-level ontologies associated with lexical information by taking into account part-whole subsumption. As we consider that parts may subsume (...) wholes under specific conditions, ontologies can be defined in terms of systems in which wholes inherit information from its parts. In this article, we describe how part-whole subsumption and, then, meronymic inheritance can be used to deal with type mismatch and metonymic interpretation of polysemous nouns. For this purpose, we attempt to merge old assumptions from both formal ontology and lexical semantics into a homogeneous framework. (shrink)

This article provides a survey of key topics on just inheritance taxation. It does so by first presenting the main arguments in the debate. Here, I distinguish between arguments in the academic literature and the various arguments which have proven important in the public debate. Secondly, I outline four influential proposals when it comes to how inheritance should be taxed. Finally, I examine a recent controversy and point towards a number of themes that have not been sufficiently discussed.

Slavery harmed the slaves but not their descendants since slavery brought about their existence. The descendants gain the slaves’ claims via inheritance. However, collecting the inheritance-based claim runs into a number of difficulties. First, every descendant usually has no more than a portion of the slave’s claim because the claim is often divided over generations. Second, there are epistemic difficulties involving the ownership of the claim since it is unlikely that a descendant of a slave several generations removed (...) would have retained the claim of inheritance given the loss of wealth and disinheritance that often characterizes families. There are also problems in determining the amount of inheritance. This is in part because of the problems of calculating in the effects of offsets, especially crime-related offsets, which are owed by a significant portion of the descendants. Even if this inheritance claim can be established with sufficient confidence certain entities may not be asked to pay it. The federal government does not owe compensation since as a historical matter it permitted but did not cause enslavement. The beneficiaries of slavery do not owe compensation since merely receiving the benefit of an unjust activity does not by itself generate a debt of compensation. When combined these problems constitute an overwhelming case against reparations. (shrink)

Review of Francoise Baylis, Altered Inheritance: CRISPR and the Ethics of Human Genome Editing (2019).

What role does non-genetic inheritance play in evolution? In recent work we have independently and collectively argued that the existence and scope of non-genetic inheritance systems, including epigenetic inheritance, niche construction/ecological inheritance, and cultural inheritance—alongside certain other theory revisions—necessitates an extension to the neo-Darwinian Modern Synthesis (MS) in the form of an Extended Evolutionary Synthesis (EES). However, this argument has been challenged on the grounds that non-genetic inheritance systems are exclusively proximate mechanisms that serve (...) the ultimate function of calibrating organisms to stochastic environments. In this paper we defend our claims, pointing out that critics of the EES (1) conflate non-genetic inheritance with early 20th-century notions of soft inheritance; (2) misunderstand the nature of the EES in relation to the MS; (3) confuse individual phenotypic plasticity with trans-generational non-genetic inheritance; (4) fail to address the extensive theoretical and empirical literature which shows that non-genetic inheritance can generate novel targets for selection, create new genetic equilibria that would not exist in the absence of non-genetic inheritance, and generate phenotypic variation that is independent of genetic variation; (5) artificially limit ultimate explanations for traits to gene-based selection, which is unsatisfactory for phenotypic traits that originate and spread via non-genetic inheritance systems; and (6) fail to provide an explanation for biological organization. We conclude by noting ways in which we feel that an overly gene-centric theory of evolution is hindering progress in biology and other sciences. (shrink)
