In evolution, large-scale changes that involve the origin of complex new traits occur gradually, in a broad sense of the term. This principle applies to the origin of subjective or felt experience. I respond to difficulties that have been raised for a gradualist view in this area, and sketch a scenario for the gradual evolution of subjective experience, drawing on recent research into early nervous system evolution.

Epistemic absolutism holds that knowledge‐that is ungradable, while epistemic gradualism argues the opposite. This paper purports to remodel the gradualism/absolutism debate. The current model initiated by Stephen Hetherington fails to capture the genuine divergence between the two views, which makes the debate equivocal, and the gradualist side lacks appeal. I propose that the remodeled debate should focus on whether knowledge‐that is a ‘threshold concept’ or a ‘spectrum concept’. That is, whether there is a threshold distinguishing knowledge from non‐knowledge. (...) The reconstructed model enjoys significant advantages as it enables the debate to be more balanced and philosophically interesting. (shrink)

Evolutionary gradualism, the randomness of mutations, and the hypothesis that natural selection exerts a pervasive and substantial influence on evolutionary outcomes are pair-wise logically independent. Can the claims about selection and mutation be used to formulate an argument for gradualism? In his Genetical Theory of Natural Selection, R.A. Fisher made an important start at this project in his famous “geometric argument” by showing that a random mutation that has a smaller effect on two or more phenotypes will have (...) a higher average fitness than a random mutation that has a larger phenotypic effect. Motoo Kimura’s demonstration that a gene’s probability of fixation depends on both the selection coefficient and the effective population size shows that Fisher’s argument for gradualism was mistaken. Here we analyze Fisher’s argument and explain how Kimura’s theory leads to a conclusion that Fisher did not anticipate. We identify a fallacy that reasoning about fitness differences and their evolutionary consequences should avoid. We then distinguish forward-directed from backward-directed versions of gradualism. The backward-directed thesis about a single mutation may be correct, but the forward-directed thesis is not. After that we consider a sequence of random mutations that all affect the same cluster of phenotypes and Allen Orr’s idea that there is an optimal sequence of mutation sizes, moving from larger to smaller as the population approaches a fixed optimum. This provides a likelihood justification for a forward-directed version of gradualism when there is a fixed optimum, but it also provides an argument against forward-directed gradualism if the optimum shifts substantially as the population evolves. Finally, we consider whether genome-wide association studies (GWASs) can furnish empirical evidence that bears on the truth of gradualism. The version of gradualism that GWASs directly bear on concerns the phenotypic effect size of a gene after it arises by mutation and has reached an appreciable frequency, not the phenotypic size of the mutation event itself.

An epistemological orthodox view holds that knowing that p is an absolute ‘yes-or-no’ affair rather than something that comes in degrees. The rising epistemic gradualist theory challenges this orthodoxy by arguing that knowledge-that is a gradable concept. The predominant form of argument for gradualism in the current literature is the argument from component, according to which knowledge is gradable because its various components (e.g., justification, belief, truth) are gradable. I will show that the argument from components involves a non-sequitur: (...) the alleged gradability of knowledge’s components cannot ensure the gradability of knowledge per se. The crux of this logical lacuna lies in that the argument neglects the external gradability of knowledge, viz, there is no clear-cut threshold between knowledge and lack thereof. The lacuna can be mended by seeing knowledge-that as a spectrum concept such that a more complete gradualist picture can be achieved. (shrink)

When reasoning about dependence relations, philosophers often rely on gradualist assumptions, according to which abrupt changes in a phenomenon of interest can only result from abrupt changes in the low-level phenomena on which it depends. These assumptions, while strictly correct if the dependence relation in question can be expressed by continuous dynamical equations, should be handled with care: very often the descriptively relevant property of a dynamical system connecting high- and low-level phenomena is not its instantaneous behavior, but its stable (...) fixed points (those in the vicinity of which it spends most of the time, after comparatively short transitory periods), and stable fixed points can change abruptly as a result of infinitesimal changes of the low-level phenomenon. We illustrate this potential gradualist trap by showing that Chalmers’s fading qualia argument falls in it. (shrink)

Many attempts have been made at supporting either one of the allegedly complementary divergence models Phyletic Gradualism and Punctuated Equilibria by patterns found in specific fossil sequences. However, assessing each model's connection with reality via such “individual case histories” appears not to constitute a relevant approach. Instead, in order to correctly establish the possible merits of both concepts, the claims of each have to be verified against general evolutionary theory. This is being pointed out herein by analyzing cladogenesis at (...) the specific level as an example.

This paper responds to Stephen Hetherington's discussion of my ‘Is Fallibility an Epistemological Shortcoming?’ (2004). The Infallibilist skeptic holds that in order to know something, one must be able to rule out every possible alternative to the truth of one’s belief. This requirement is false. In this paper I first clarify this requirement’s relation to our ordinary practice. I then turn to a more fundamental issue. The Infallibilist holds – along with many non-skeptical epistemologists – that Infallibility is epistemically superior (...) to the epistemic position attained when we have (what we ordinarily call) knowledge. This is false, too, as our ordinary practices show. Ordinary epistemic appraisal does not concern our standing on a scale of evaluation which has Infallibility at its apex. For this reason, even if gradualism is correct, it does not show how Infallibilist skepticism can arise out of our ordinary practice. (shrink)

The distinction between the context ofdiscovery and the context of justificationrestricts philosophy of science to the rationalreconstruction of theories, and characterizesscientific discovery as rare, theoreticalupheavals that defy rational reconstruction. Kuhnian challenges to the two contextsdistinction show that non-rational elementspersist in the justification of theories, butgo no further to provide a positive account ofdiscovery. A gradualist theory of discoverydeveloped in this paper shows, with supportfrom ecological cases, that discoveries areroutinely made in ecology by extending modelsto new domains, or by making additions (...) toearlier models. The logic of discovery isphilosophically accessible once it isappreciated that model truth is presumed, evenif counterfactually, in ecologists' applicationof models. A gradualist view shows thatmodels' heuristic power routinely leads todiscoveries. (shrink)

In Darwin’s Black Box, Michael J. Behe argues that, because certain biochemical systems are both irreducibly complex and very complex, it is extremely unlikely that they evolved gradually by Darwinian mechanisms, and so extremely likely that they were intelligently designed. I begin this paper by explaining Behe’s argument and defending it against the very common but clearly mistaken charge that it is just a rehash of William Paley’s design argument. Then I critically discuss a number of more serious objections to (...) the argument. I conclude that, while Behe successfully rules out some Darwinian paths to the biochemical systems he discusses, others remain open. Thus, his argument against Darwinian gradualism (and ipso facto his argument for intelligent design) is at best incomplete. (shrink)

The major tenets of the recent hypothesis of punctuated equilibrium are explicit in Darwin's writing. His notes from 1837–1838 contain references to stasis and rapid change. In the first edition of the Origin (1859), Darwin described the importance of isolation of local varieties in the process of speciation. His views on the tempo of speciation were influenced by Hugh Falconer and also, perhaps, by Edward Suess (1831–1914). It is paradoxical that, although both topics were recorded in his unpublished notes of (...) 1837–1838, the second was not explicitly and fully discussed until the fourth edition of the Origin (1866). While no wholly satisfactory explanation of this paradox suggests itself, it seems probable that Falconer's work on the persistence of fossil species of elephant helped Darwin to see the wider significance of the tempo of evolution for his general theory.

Resumo Recentemente o Hilemorfismo – a visão tradicional, segundo a qual, as substâncias são constituídas pela combinação de forma e matéria – tem sido alvo de renovado interesse. Este artigo centra-se na substância material e sugere que, neste caso, a constituição hilemórfica exige uma noção de forma que deve ser alargada ao conceito de energia, ou ao exercício de uma força. Neste artigo também se defende o gradualismo substancial: se a forma for assim entendida, a substancialidade possui graus, ou seja, (...) as coisas podem ser substâncias em maior ou menor grau. O gradualismo substancial pode iluminar os actuais debates relativos à identificação das partes das substâncias e à compatibilidade entre o hilemorfismo e o categorialismo. Palavras-chave : forma, gradualismo substancial, hilemorfismo, matéria, substânciaHylomorphism, the old traditional view according to which substances are constituted by the combination of form and matter, has recently undergone a renaissance. This essay focuses on material substance, and suggests that in this case the hylomorphic constitution calls for a notion of form which should be understood also as energy, or the exercise of a force. It further argues for substantial gradualism: when form is thus understood, substantiality comes in degrees, i.e. things can be substances to a greater or lesser degree. Substantial gradualism sheds new light on current discussions concerning the identification of the parts of substances and the compatibility between hylomorphism and sortalism.

Classical presentations of the Buddhist path prescribe the cultivation of various good qualities that are necessary for spiritual progress, from mindfulness and loving-kindness to faith and wisdom. Examining the way in which such qualities are described and classified in early Buddhism—with special reference to their treatment in the Visuddhimagga by the fifth-century Buddhist thinker Buddhaghosa—the present article employs a comparative method in order to identify the Buddhist catalog of virtues. The first part sketches the characteristics of virtue as analyzed by (...) neo-Aristotelian theories. Relying on these accounts, the second part considers three lists from early Buddhism as possible catalogs of virtue: the components of ethical conduct, the 37 factors that contribute to awakening, and the wholesome or beautiful mental factors. I then raise the question of why the Buddhist tradition developed several classifications of virtue, whereas the Western tradition of virtue ethics used a single category. Appealing to the connection between the virtues and living well in the eudaimonistic version of virtue ethics, I propose that one of the reasons why Buddhism developed multiple lists of virtues is its pluralistic acceptance of different modalities of living well and associated practices, in MacIntyre’s sense of the term. These modalities and practices are not equal, but are ordered hierarchically. Accordingly, I conclude that Buddhist ethics ought to be seen as a pluralist-gradualist system rather than a universalist theory. (shrink)

According to standard comparativist views, death is bad insofar as it deprives someone of goods she would otherwise have had. In The Ethics of Killing, Jeff McMahan argues against such views and in favor of a gradualist account according to which how bad it is to die is a function of both the future goods of which the decedent is deprived and her cognitive development when she dies. Comparativists and gradualists therefore disagree about how bad it is to die at (...) different ages. In this paper I examine two prominent criticisms of gradualism and show that both misconstrue McMahan. I develop a related criticism that seems to show that a gradualist cannot coherently relate morbidity and mortality. This criticism also fails, but has an instructive implication for how policy-makers setting priorities for health care investments should regard choices between life-saving interventions and interventions against non-fatal diseases in the very young.

It is an issue of already longstanding significance in philosophy of religion after John Hick, that is of differing models of religious consciousness, in the frame of interreligious relations which is tackled in the paper but it is done on the basis of the texts of a concrete philosopher and the narratives around his figure. One of the most eminent Naiyayikas, Udayana, is singled out, as the author of the very renown composition in verse Nyāyakusumaňjali offering arguments for the existence (...) of God in the framework of polemics with the anti-theistic schools and the anti-Buddhist fundamental compendium Ātmatattvaviveka, along with the stories about his very resolute and victorious struggle against Buddhism in the epoch of the latter’s final extirpation from India. The author comes to conclusion that the features of exclusivism, inclusivism and gradualism are detected in his texts and traditions around him and, therefore, any univocal authentication of his attitude to otherwise-minded and those of other faiths is impossible. While participating in the supplantation of Buddhism from India, Udayana displays very resolute exclusivism. When he addresses the educated audience sermonizing his philosophical theism, he uses purely inclusivistic strategy of uncovering implicit knowledge of Īśvara even with those very far removed from the truth. And when he attempts to locate Nyāya on the map of philosophical world-views he uses gradualism as “philosophy of ascent” of the truth from lower to higher levels. As is impossible as well to mark out of his attitudes the so-called pluralism considered by Hick as fundamental advantage of Eastern religions over the Western ones. Comparativistic parallels along with differences and some specification of the main categories of interreligious relations are also offered in the paper. (shrink)

My question is the following: to what extent is ethical anthropocentrism tenable? In a “discourse ethical” perspective I will consider some case-oriented arguments in favor of a paradigmatically unique ethical standing for humans and some arguments in favor of an ethical gradualism between humans and other mammals and between humans and nature, ending with a conclusion in favor of a fair treatment of all moral subjects, human and non-human.

They are correct that punctuated equilibria apply to sexually reproducing organisms and that morphological evolutionary change is regarded as largely (if not exclusively) correlated with speciation events. However, they err in suggesting that we attribute stasis strictly to "developmental constraints," which represent only one of a set of possible mechanisms that we have suggested for the causes of stasis. Others include habitat tracking and the internal structure of species themselves [for example, (2)].

Any knowledge-fallibilist needs to solve the conceptual problem posed by concessive knowledge-attributions (such as ‘I know that p, but possibly not-p’). These seem to challenge the coherence of knowledge-fallibilism. This paper defuses that challenge via a gradualist refinement of what Fantl and McGrath (2009) call weak epistemic fallibilism.

The dissertation has two parts, each dealing with a problem, namely: 1) What is the most adequate account of fuzziness -the so-called phenomenon of vagueness?, and 2) what is the most plausible solution to the sorites, or heap paradox? I will try to show that fuzzy properties are those which are gradual, amenable to be possessed in a greater or smaller extent. Acknowledgement of degrees in the instantiation of a property allows for a gradual transition from one opposite to the (...) other, each intermediate stage constituting an overlap in certain proportion of both contraries. Hence, degrees in the possession of a property give rise to simple contradictions. The reason why I have chosen those two questions is that they provide the main philosophical motivation for a particular brand of an infinite valued and paraconsistent logic. I will claim that Classical logic (CL) is not adequate to handle fuzzy situations, and, being deficient, is in need of being expanded to make room for degrees of truth and weak contradictions. One can hardly deny the importance of the debate, since what is ultimately at stake is what the limits of truth, rationality, intelligibility and possibility are. The main disciplines within which the research moves are the philosophy of language, philosophy of logic, and ontology. (shrink)

In Chapter Five of The Mind Doesn’t Work That Way, Jerry Fodor argues that since it is likely that human minds evolved quickly as saltations rather than gradually as the product of an accumulation of small mutations, evolutionary psychologists are wrong to think that human minds are adaptations. I argue that Fodor’s requirement that adaptationism entails gradualism is wrongheaded. So, while evolutionary psychologists may be wrong to endorse gradualism—and I argue that they are wrong—it does not follow that (...) they are wrong to endorse an adaptationist explanation for how the human mind evolved.

This essay draws on Adam Smith’s moral sentimentalism to critique primatologist Frans de Waal’s gradualist theory of human morality. De Waal has spent his career arguing for continuity between primate behavior and human morality, proposing that empathy is a primary moral building block evident in primate behavior. Smith’s moral sentimentalism—with its emphasis on the role of sympathy in moral virtue—provides the philosophical framework for de Waal’s understanding of morality. Smith’s notion of sympathy and the imagination involved in sympathy is qualitatively (...) different from animal sympathy. I argue that Smithian sympathy includes the ability to represent propositional attitudes and take into account multiple perspectives which are then synthesized into a singular impartial perspective. Furthermore, Smithian moral judgment requires the capacity for emotion regulation and moral self-cultivation, or the ability to shape and control one’s reactive attitudes. Taken together, these capacities far outstrip the capacities of animals, disrupting de Waal’s gradualism. (shrink)

What are we, most fundamentally? Two topical answers to this question are discussed and rejected and a more evolutionary account is offered. Lynne Baker argues that we are persons: beings with a first-person perspective. Persons form a separate ontological category, with persistence conditions that are different from those of the body. Eric Ol-son, by contrast, claims that we are human organisms. No psychological property is definitive of what we are. Our persistence conditions are those of the human organism. In a (...) more evolutionary approach to the notion of personhood, it is argued that we are indeed, most fundamentally, beings with a first-person perspective. But such a perspective is not definitive of personhood. It is precisely living organisms that have it, and cannot fail to have it. There is no separate ontological category of persons. (shrink)

Epistemic absolutism is an orthodox view that propositional knowledge is an ungradable concept. Absolutism is primarily grounded in our ungradable uses of “knows” in ordinary language. This paper advances a thorough objection to the linguistic argument for absolutism. My objection consists of two parts. Firstly, arguments for absolutism provided by Jason Stanley and Julien Dutant will be refuted respectively. After that, two more general refutation-strategies will be proposed: counterevidence against absolutism can be found in both English and non-English languages; the (...) linguistic argument for absolutism is subject to a methodological mistake as the linguistic usages of “knows” cannot accurately reflect its conceptual nature. Therefore, we should give epistemic gradualism, as opposed to absolutism, a more serious consideration. (shrink)

In philosophy, as in any other theoretical endeavor, it is not rare to find conflicting but equally well grounded positions. Besides defending one of the positions and criticizing the other, philosophers can opt for pursuing other, more sophisticated, approaches aimed at incorporating the insights, intuitions, and arguments from both sides of the debate into a unified theory: Dialetheism, Analetheism, Gradualism, Pluralism and Relativism. The purpose of this article is to present each strategy's basic argumentative structure, relative strengths, and challenges, (...) trying to determine in which situations one is more appropriate than the others. Despite substantial differences between them, all four options have deep structural similarities; and which option is better for which dilemma or paradox will depend ultimately on a combination of epistemological, linguistic, and metaphysical factors.

In psychiatry there is no sharp boundary between the normal and the pathological.

Part II encompasses historical and recent philosophical positions on gradualist approaches to health and disease. Part III approaches the vagueness of present psychiatric classification systems, and the debates concerning their revisions by scrutinizing controversial categories, such as posttraumatic stress disorder, and the difficulties of day-to-day diagnostic and therapeutic practice. Part IV finally focuses on social, moral, and legal implications that arise when being mentally ill is a matter of degree. (shrink)

Gradual progress, the need for a balance of the forces under the State’s power, and the balance between State and society are vital for the preservation of freedom.

Species are thought by many to be important units of evolution. In this paper, I argue against that view. My argument is based on an examination of the role of species in the synthetic theory of evolution. I argue that if one adopts a gradualist view of evolution, one cannot make sense of the claim that species are units in the minimal sense needed to claim that they are units of evolution, namely, that they exist as discrete entities over time. (...) My second argument is directed against an appeal to Eldredge and Gould's theory of punctuated equilibria to support the claim that species are units of evolution. If one adopts their view, it may be possible to identify discrete temporal entities that can plausibly be termed species, but there is no reason to claim that those entities are units of evolution. Thus, on two plausible interpretations of the role of natural selection in the process of evolution, species are of no special importance. I then consider some of the reasons why species have been thought to be important evolutionary units by many contemporary evolutionary biologists. Finally, I discuss briefly the implications of this conclusion for evolutionary biology. (shrink)

In this paper, I focus on four main points: I delineate what I see as the strength and relevance of transcendental-pragmatics within the intellectual setting in the post-war period.

Perhaps the gradualist position on abortion has re-emerged repeatedly because it corresponds to pastoral experienceAt one level David Albert Jones’s paper is very successful. Despite the high reputation of the late Gordon Dunstan, first as a mediaeval historian, then as an ethicist of considerable influence within the Anglican church, and finally as a pioneer medical ethicist, his crucial 1984 article appears to be overdrawn. Some caution is now needed before endorsing his claim that the Christian tradition according the embryo the (...) full moral status of a human person from conception is “virtually a creation of the later nineteenth century”. Dr Jones produces a wealth of historical scholarship to challenge it.At another level, however, Dr Jones is not concerned about nuancing a historical claim but about demonstrating that “licensing destructive research on human embryos for the sake of medical progress…cannot be justified…on the basis of the Christian tradition”.1 Unfortunately there is quite a large gap between these two claims. Manifestly “the Christian tradition” is not a unified tradition even within Jones’s own historical account.

In this article, we analyze and reject two versions of the content‐argument against animal beliefs, namely, the ontological argument from Davidson and the epistemological argument from Stich.

Appealing to reason rather than religious belief, this book is the most comprehensive case against the choice of abortion yet published. This _Second Edition_ of _The Ethics of Abortion _critically evaluates all the major grounds for denying fetal personhood, including the views of those who defend not only abortion but also post-birth abortion. It also provides several justifications for the conclusion that all human beings, including those in utero, should be respected as persons. This book also critiques the view that (...) abortion is not wrong even if the human fetus is a person. _The Ethics of Abortion _examines hard cases for those who are prolife, such as abortion in cases of rape or in order to save the mother’s life, as well as hard cases for defenders of abortion, such as sex selection abortion and the rationale for being "personally opposed" but publically supportive of abortion. It concludes with a discussion of whether artificial wombs might end the abortion debate. Answering the arguments of defenders of abortion, this book provides reasoned justification for the view that all intentional abortions are ethically wrong and that doctors and nurses who object to abortion should not be forced to act against their consciences. Updates and Revisions to the Second Edition include: -A response to Alberto Giubilini’s and Francesca Minerva’s now famous 2012 article, "After-Birth Abortion" in the _Journal of Medical Ethics _ -Responses to new defenses of Judith Jarvis Thomson’s violinist argument -The addition of a new chapter on gradualist views of fetal moral worth, including Jeff McMahan’s Time-Relative Interest Account -The addition of a new chapter on the conscience protection for health care workers who are opposed to abortion -Responses to many critiques of the first edition, including those made by Donald Marquis, David DeGrazia, and William E.

Ernst Mayr has argued that Darwinian theory discredited essentialist modes of thought and replaced them with what he has called "population thinking". In this paper, I characterize essentialism as embodying a certain conception of how variation in nature is to be explained, and show how this conception was undermined by evolutionary theory. The Darwinian doctrine of evolutionary gradualism makes it impossible to say exactly where one species ends and another begins; such line-drawing problems are often taken to be the (...) decisive reason for thinking that essentialism is untenable. However, according to the view of essentialism I suggest, this familiar objection is not fatal to essentialism. It is rather the essentialist's use of what I call the natural state model for explaining variation which clashes with evolutionary theory. This model implemented the essentialist's requirement that properties of populations be defined in terms of properties of member organisms. Requiring such constituent definitions is reductionistic in spirit; additionally, evolutionary theory shows that such definitions are not available, and, moreover, that they are not needed to legitimize population-level concepts. Population thinking involves the thesis that population concepts may be legitimized by showing their connections with each other, even when they are not reducible to concepts applying at lower levels of organization. In the paper, I develop these points by describing Aristotle's ideas on the origins of biological variation; they are a classic formulation of the natural state model. I also describe how the development of statistical ideas in the 19th century involved an abandoning of the natural state model. (shrink)

ntroduction Since China’s gradualist reform started in the early 1980s, its governance record has been relatively successful. Despite a large number of severe challenges, the government in Beijing has managed outstanding economic performance and large-scale social transformation (Naughton 2007). Overall, the regime seems to enjoy relatively high levels of public support (Gilley 2006; Wang 2009), and a reform and state-building process controlled by the ruling Chinese Communist Party looks set to continue for the next ten to 20 years. One key (...) element of the Chinese political or governing system is management of its Party and government officials, or “cadres” in its own terminology. We argue that the Party-state’s personnel management features a meritocratic system that has so far largely evaded scholarly attention. This system retains strong influences from the Confucian scholar-official tradition of China’s imperial past, as well as the Leninist “vanguard party” tradition that was established in the revolutionary and Maoist eras. In recent years, however, this system has paid increasing attention to nurturing managerial competence for the purpose of administering a modern economy and a modern society. How the Party attempts to strike a balance between political loyalty and professional competence is the focus of this study. We will examine several aspects of the Chinese cadre management system. These include the formal rules, institutions, and actual practices regarding (1) recruitment, (2) development, and (3) promotion of officials. From this analysis we will understand how political loyalty and professional competence are defined and measured in the Party’s personnel regime, and how a balance is sought between the two. We will also look at the changes that are taking place in the relative importance, or weights, of these two criteria as the Party-state tries to build a modern governance machine. We find that while political reliability and commitment still feature prominently when the Party staffs the state and party bodies, rapid economic development and social changes have amplified the need for capable and competent managers and administrators, in order to deliver successful governance. Whereas in the past political loyalty played a crucial role for officials’ success within the state ranks, today professional competence has become more central. Whether this trend will continue, to a future state in which political loyalty becomes almost irrelevant, will be discussed toward the end of the chapter. (shrink)

This paper examines whether there are moral differences between the mitochondrial replacement techniques that have been recently developed in order to help women afflicted by mitochondrial DNA diseases to have genetically related children absent such conditions: maternal spindle transfer and pronuclear transfer. Firstly, it examines whether there is a moral difference between MST and PNT in terms of the divide between somatic interventions and germline interventions. Secondly, it considers whether PNT and MST are morally distinct under a therapy/creation optic. Finally, (...) it investigates whether there is a moral difference between MST and PNT from a human embryo destruction point of view. I conclude, contra recent arguments, that regarding the first two points there is no moral differences between PNT and MST; and that regarding the third one MST is morally preferable to PNT, but only if we hold a gradualist account of the moral value of human embryos where zygotes have slight moral value.

There are many questions we can ask about time, but perhaps the most fundamental is whether there are metaphysically interesting differences between past, present and future events. An eternalist believes in a block universe: past, present and future events are all on an equal footing. A gradualist believes in a growing block: he agress with the eternalist about the past and the present but not about the future. A presentist believes that what is present has a special status. My first (...) claim is that the familiar ways of articulating these views result in there being no substantive disagreement at all between the three parties. I then show that if we accept the controversial truthmaking principle, we can articulate a substantive disagreenment. Finally, I apply this way of formulating the debate to related questions such as the open future and determinism, showing that these do not always line up in quite the way one would expect. (shrink)

Of two contending models for eukaryotic evolution the “archezoan“ has an amitochondriate eukaryote take up an endosymbiont, while “symbiogenesis“ states that an Archaeon became a eukaryote as the result of this uptake. If so, organelle formation resulting from new engulfments is simplified by the primordial symbiogenesis, and less informative regarding the bacterium‐to‐mitochondrion conversion. Gradualist archezoan visions still permeate evolutionary thinking, but are much less likely than symbiogenesis. Genuine amitochondriate eukaryotes have never been found and rapid, explosive adaptive periods characteristic of (...) symbiogenetic models explain this. Mitochondrial proteomes, encoded by genes of “eukaryotic origin“ not easily linked to host or endosymbiont, can be understood in light of rapid adjustments to new evolutionary pressures. Symbiogenesis allows “expensive” eukaryotic inventions via efficient ATP generation by nascent mitochondria. However, efficient ATP production equals enhanced toxic internal ROS formation. The synergistic combination of these two driving forces gave rise to the rapid evolution of eukaryotes.Also watch the Video Abstract. (shrink)
