The placozoan Trichoplax adhaerens is a tiny hairy plate and more simply organized than any other living metazoan. After its original description by F.E. Schulze in 1883, it attracted attention as a potential model for the ancestral state of metazoan organization, the “Urmetazoon”. Trichoplax lacks any kind of symmetry, organs, nerve cells, muscle cells, basal lamina, and extracellular matrix. Furthermore, the placozoan genome is the smallest (not secondarily reduced) genome of all metazoan genomes. It harbors a remarkably rich diversity of (...) genes and has been considered the best living surrogate for a metazoan ancestor genome. The phylum Placozoa presently harbors three formally described species, while several dozen “cryptic” species are yet awaiting their description. The phylogenetic position of placozoans has recently become a contested arena for modern phylogenetic analyses and view‐driven claims. Trichoplax offers unique prospects for understanding the minimal requirements of metazoan animal organization and their corresponding malfunctions. (shrink)

The placozoan Trichoplax adhaerens has been bridging gaps between research disciplines like no other animal. As outlined in part 1, placozoans have been subject of hot evolutionary debates and placozoans have challenged some fundamental evolutionary concepts. Here in part 2 we discuss the exceptional genetics of the phylum Placozoa and point out some challenging model system applications for the best known species, Trichoplax adhaerens.

The emergentist position that R. Keith Sawyer has formulated, nonreductive individualism, contains three propositions. First, that social characteristics must always be realized in individuals; second, that it is nevertheless possible to understand social properties as irreducible; and third, that therefore it is possible to demonstrate how social properties are able to exercise independent causal influences on individuals and their properties. It is demonstrated that Sawyer is not able to meet an objection that Kim has formulated against the analogous position in (...) the philosophy of mind. In his defense of the claim of irreducibility Sawyer refers to Fodor’s argument about multiple realizability, but this line of argument cannot preserve the claim for downward causation because Fodor’s claim for irreducibility rests on assumptions that are not compatible with a systematic formulation of downward causation. The article proposes a reading of Fodor’s argument that is consistent with individualism but not with nonreductive individualism. (shrink)

The mechanistic view of computation contends that computational explanations are mechanistic explanations. Mechanists, however, disagree about the precise role that the environment – or the so-called “contextual level” – plays for computational explanations. We advance here two claims: Contextual factors essentially determine the computational identity of a computing system ; this means that specifying the “intrinsic” mechanism is not sufficient to fix the computational identity of the system. It is not necessary to specify the causal-mechanistic interaction between the system and (...) its context in order to offer a complete and adequate computational explanation. While the first claim has been discussed before, the second has been practically ignored. After supporting these claims, we discuss the implications of our contextualist view for the mechanistic view of computational explanation. Our aim is to show that some versions of the mechanistic view are consistent with the contextualist view, whilst others are not. (shrink)

Possible-worlds accounts of mental or linguistic content are often criticized for being too coarse-grained. To make room for more fine-grained distinctions among contents, several authors have recently proposed extending the space of possible worlds by "impossible worlds". We argue that this strategy comes with serious costs: we would effectively have to abandon most of the features that make the possible-worlds framework attractive. More generally, we argue that while there are intuitive and theoretical considerations against overly coarse-grained notions of content, the (...) same kinds of considerations also prohibit an overly fine-grained individuation of content. An adequate notion of content, it seems, should have intermediate granularity. However, it is hard to construe a notion of content that meets these demands. Any notion of content, we suggest, must be either implausibly coarse-grained or implausibly fine-grained (or both). (shrink)

According to the standard version of the counterfactual comparative account of harm, an event is overall harmful for an individual if and only if she would have been on balance better off if it had not occurred. This view faces the “preemption problem.” In the recent literature, there are various ingenious attempts to deal with this problem, some of which involve slight additions to, or modifications of, the counterfactual comparative account. We argue, however, that none of these attempts work, and (...) that the preemption problem continues to haunt the counterfactual comparative account. (shrink)

This work is a systematic investigation of a range of solutions offered today for the philosophical problem of mental causation. The premises constituting the problem are analyzed before a survey is developed of the most popular theories on mental causation. It is demonstrated in detail why most of these canonical solutions must be considered deficient. In a third part, the 'new compatibilist's' approach to mental causation is explored, which is characterized by assertion of a non-identity-but-non-distinctness principle. The last part aims (...) to offer an alternative solution to the problem. On the basis of a certain set of counterfactual conditionals, which are jointly taken to provide a definition of 'causal proportionality' that improves the existing definitions, it is shown that a specific, and hitherto widely neglected, version of causal overdeterminationism must be considered the most successful solution to the problem of mental causation.

The counterfactual comparative account of harm faces problems in cases that involve overdetermination and preemption. An influential strategy for dealing with these problems, drawing on a suggestion made by Derek Parfit, is to appeal to _plural harm_—several events _together_ harming someone. We argue that the most well-known version of this strategy, due to Neil Feit, as well as Magnus Jedenheim Edling’s more recent version, is fatally flawed. We also present some general reasons for doubting that the overdetermination and preemption problems (...) for the counterfactual comparative account can be satisfactorily solved by appealing to plural harm.

The Groundwork of the Metaphysics of Morals is Kant's central contribution to moral philosophy, and has inspired controversy ever since it was first published in 1785. Kant champions the insights of 'common human understanding' against what he sees as the dangerous perversions of ethical theory. Morality is revealed to be a matter of human autonomy: Kant locates the source of the 'categorical imperative' within each and every human will. However, he also portrays everyday morality in a way that many readers (...) find difficult to accept. The Groundwork is a short book, but its argument is dense, intricate and at times treacherous. This commentary explains Kant's arguments paragraph by paragraph, and also contains an introduction, a synopsis of the argument, six short interpretative essays on key topics of the Groundwork, and a glossary of key terms. It will be an indispensable tool for anyone wishing to study the Groundwork in detail. (shrink)

A prominent objection to the counterfactual comparative account of harm is that it classifies as harmful some events that are, intuitively, mere failures to benefit. In an attempt to solve this problem, Duncan Purves has recently proposed a novel version of the counterfactual comparative account, which relies on a distinction between making upshots happen and allowing upshots to happen. In this response, we argue that Purves’s account is unsuccessful. It fails in cases where an action makes the subject occupy a (...) high well-being level though one of the available alternatives would have made it even higher. In fact, it fails even in some cases where each of the available alternatives to the action that was actually performed would have made the subject’s well-being level lower. (shrink)

According to the “deprivation approach,” a person’s death is bad for her to the extent that it deprives her of goods. This approach faces the Lucretian problem that prenatal non-existence deprives us of goods just as much as death does, but does not seem bad at all. The two most prominent responses to this challenge—one of which is provided by Frederik Kaufman (inspired by Thomas Nagel) and the other by Anthony Brueckner and John Martin Fischer—claim that prenatal non-existence is relevantly (...) different from death. This paper criticizes these responses. (shrink)

IntroductionIf we were to identify the beginning of the study of visual argumentation, we would have to choose 1996 as the starting point. This was the year that Leo Groarke published “Logic, art and argument” in Informal logic, and it was the year that he and David Birdsell co-edited a special double issue of Argumentation and Advocacy on visual argumentation . Among other papers, the issue included Anthony Blair’s “The possibility and actuality of visual arguments”. It was also the year (...) that Gail J. Chryslee, Sonja K. Foss and Arthur L. Ranney published their short text on “The construction of claims in visual argumentation” , stating that even though theorists may know a great deal about the process of argumentation, “virtually none of this knowledge is applicable to visual argumentation […] because of the properties that distinguish visual imagery from discursive symbols” .Texts on visual rhetoric have been written as far back as the early 1980s, ..

In this paper, we critically examine Molly Gardner’s favored solution to what she calls “the problem of justified harm.” We argue that Gardner’s view is false and that her arguments in support of it are unconvincing. Finally, we briefly suggest an alternative solution to the problem which avoids the difficulties that beset Gardner’s proposal.

This paper discusses the relevance of models for cognitive science that integrate mechanistic and computational aspects. Its main hypothesis is that a model of a cognitive system is satisfactory and explanatory to the extent that it bridges phenomena at multiple mechanistic levels, such that at least several of these mechanistic levels are shown to implement computational processes. The relevant parts of the computation must be mapped onto distinguishable entities and activities of the mechanism. The ideal is contrasted with two other (...) accounts of modeling in cognitive science. The first has been presented by David Marr in combination with a distinction of “levels of computation”. The second builds on a hierarchy of “mechanistic levels” in the sense of Carl Craver. It is argued that neither of the two accounts secures satisfactory explanations of cognitive systems. The mechanistic-computational ideal can be thought of as resulting from a fusion of Marr’s and Craver’s ideals. It is defended as adequate and plausible in light of scientific practice, and certain metaphysical background assumptions are discussed. (shrink)

Counterfactual conditionals have been appealed to in various ways to show how the mind can be causally efficacious. However, it has often been overestimated what the truth of certain counterfactuals actually indicates about causation. The paper first identifies four approaches that seem to commit precisely this mistake. The arguments discussed involve erroneous assumptions about the connection of counterfactual dependence and genuine causation, as well as a disregard of the requisite evaluation conditions of counterfactuals. In a second step, the paper uses (...) the insights of the foregoing analyses to formulate a set of counterfactuals-based conditions that are characterized as sufficient to establish singular causal claims. The paper concludes that there are ample reasons to believe that some mental events satisfy all these conditions with respect to certain further events and, hence, that mental events sometimes are causes.

In a recent article, I criticized Anthony L. Brueckner and John Martin Fischer’s influential argument—appealing to the rationality of our asymmetric attitudes towards past and future pleasures—against the Lucretian claim that death and prenatal non-existence are relevantly similar. Brueckner and Fischer have replied, however, that my critique involves an unjustified shift in temporal perspectives. In this paper, I respond to this charge and also argue that even if it were correct, it would fail to defend Brueckner and Fischer’s proposal against (...) my critique. (shrink)

According to epistemic two-dimensionalism, or simply two-dimensionalism, linguistic expressions are associated with two intensions, one of which represents an expression’s a priori implications. The author investigates the prospects of conceptual analysis on the basis of a two-dimensionalist theory of meaning. He discusses a number of arguments for and against two-dimensional semantics and argues that properly construed, two-dimensionalism provides a potent and plausible account of meaning. Against the background of this account, the author then goes on to assess the value of (...) conceptual analysis in philosophical practice, outlining its goals, its promises, but also its limitations.

Aufstieg zum Einen - das ist das Zentrum der Philosophie Plotins und des von ihm ausgehenden Neuplatonismus. Dass solcher Aufstieg zum Einen aber auch schon bei Platon eine zentrale Rolle spielt, gehört zu den wichtigsten Einsichten der neueren Platonforschung.

Es verbindet die erste umfassende Darstellung von Plotins Theorie des Absoluten mit einer Rekonstruktion von Platons Henologie. Dabei arbeitet es die enge Verbindung beider heraus (...) und macht zugleich die bleibende philosophische Relevanz des Themas deutlich. (shrink)

In the context of the Cold War, opinion polling as a method of observation stood for the shift from confrontation and clandestine preparations for a hot or cold civil war towards a competition between systems in the fields of political and cultural attractiveness and economic capabilities. Based on the cases of the West German polling institute Infratest and the East German Institute for Opinion Polling of the Socialist Unity Party, the article highlights the shifts in the external observation and internal (...) self-observation of socialist society with respect to the change in epistemological approaches, research topics, patterns of construction of societal structures and the confluence between political expectations, professional self-understandings and impact on policy-making processes.

This paper considers Habermas’ model of a post‐secular political order in the light of the debate on male circumcision that arose in Germany after a court ruled that male circumcision was an unjustifiable act of bodily harm. Central to this model is the idea that religious reasons can only become effective in central legal institutions when they are translated into secular reasons. My paper demonstrates that there are two distinguishable readings of this proviso. On the one hand, there is a (...) broad reading according to which it is only necessary to reach a conclusion that is in line with the democratic principle stating that all citizens can be regarded as co‐legislators even if non‐generalizable value orientations might then shape the interpretation of fundamental rights (in the case of circumcision, the right to bodily integrity). On the other hand, a truly secular (narrow) reading would avoid the inclusion of non‐generalizable value orientations. The debate on circumcision demonstrates that these two interpretations lead to different and conflicting modes of justification. The broad reading allows for a justification of male circumcision, whereas the narrow reading makes such a justification unlikely. In addition, the filtering function of the proviso is weakened in a broad reading. (shrink)

As is well-known, David Lewis’ counterfactual theory of causation is subject to serious counterexamples in ‘exceptional’ cases. What has not received due attention in the literature so far is that Lewis’ theory fails to provide necessary and sufficient conditions for causation in ‘ordinary’ cases, too. In particular, the theory suffers from the ‘problem of large causes’. It is argued that this problem may be fixed by imposing a minimization constraint, whilst this solution brings along substantial costs as well. In particular, (...) a precise formulation of minimization requires defining an ‘essential part of an event’ and/or an ‘essential subevent’. Although the possibility of such a definition is ultimately left open, some doubts are raised on whether the counterfactualists’ resources are fit for this purpose, and whether the challenge can be met without substantially departing from Lewis’ intention, which was to provide a reductive account of causation.

In a recent Utilitas article, Neil Feit argues that every person occupies a well-being level of zero at all times and possible worlds at which she fails to exist. Views like his face the problem of the subject': how can someone have a well-being level in a scenario where she lacks intrinsic properties? Feit argues that this problem can be solved by noting, among other things, that a proposition about a person can be true at a possible world in which (...) neither she nor the proposition exists. In this response, we argue that Feit has not solved the problem of the subject, and also raise various related problems for his approach. (shrink)

Many philosophers maintain that artworks, such as statues, are constituted by other material objects, such as lumps of marble. I give an argument against this view, an argument which appeals to mereological simples.

John Martin Fischer and Anthony L. Brueckner have argued that a person’s death is, in many cases, bad for him, whereas a person’s prenatal non-existence is not bad for him. Their suggestion relies on the idea that death deprives the person of pleasant experiences that it is rational for him to care about, whereas prenatal non-existence only deprives him of pleasant experiences that it is not rational for him to care about. In two recent articles in The Journal of Ethics, (...) I have objected that it is irrelevant what it is in fact rational for the person to care about. Fischer and Brueckner have replied to my critique. In this paper I respond to their latest pair of replies. (shrink)

In this paper we explore the potential bearing of the extended mind thesis—the thesis that the mind extends into the world—on epistemology. We do three things. First, we argue that the combination of the extended mind thesis and reliabilism about knowledge entails that ordinary subjects can easily come to enjoy various forms of restricted omniscience. Second, we discuss the conceptual foundations of the extended mind and knowledge debate. We suggest that the theses of extended mind and extended knowledge lead to (...) a bifurcation with respect to the concepts of belief and knowledge. We suggest that this conceptual bifurcation supports a form of pluralism about these concepts. Third, we discuss whether something similar can be said at the metaphysical level. (shrink)

Several attractive principles about prudential concern and moral responsibility seem to speak against animalism.

Predictive policing has become a new panacea for crime prevention. However, we still know too little about the performance of computational methods in the context of predictive policing. The paper provides a detailed analysis of existing approaches to algorithmic crime forecasting. First, it is explained how predictive policing makes use of predictive models to generate crime forecasts. Afterwards, three epistemologies of predictive policing are distinguished: mathematical social science, social physics and machine learning. Finally, it is shown that these epistemologies have (...) significant implications for the constitution of predictive knowledge in terms of its genesis, scope, intelligibility and accessibility. It is the different ways future crimes are rendered knowledgeable in order to act upon them that reaffirm or reconfigure the status of criminological knowledge within the criminal justice system, direct the attention of law enforcement agencies to particular types of crimes and criminals and blank out others, satisfy the claim for the meaningfulness of predictions or break with it and allow professionals to understand the algorithmic systems they shall rely on or turn them into a black box. By distinguishing epistemologies and analysing their implications, this analysis provides insight into the techno-scientific foundations of predictive policing and enables us to critically engage with the socio-technical practices of algorithmic crime forecasting.

According to popular belief, big data and machine learning provide a wholly novel approach to science that has the potential to revolutionise scientific progress and will ultimately lead to the ‘end of theory’. Proponents of this view argue that advanced algorithms are able to mine vast amounts of data relating to a given problem without any prior knowledge and that we do not need to concern ourselves with causality, as correlation is sufficient for handling complex issues. Consequently, the human contribution (...) to scientific progress is deemed to be non-essential and replaceable. We, however, following the position most commonly represented in the philosophy of science, argue that the need for human expertise remains. Based on an analysis of big data and machine learning methods in two case studies—skin cancer detection and protein folding—we show that expert knowledge is essential and inherent in the application of these methods. Drawing on this analysis, we establish a classification of the different kinds of expert knowledge that are involved in the application of big data and machine learning in scientific contexts. We address the ramifications of a human-driven expert knowledge approach to big data and machine learning for scientific practice and the discussion about the role of theory. Finally, we show that the ways in which big data and machine learning both influence and are influenced by scientific methodology involve continuous conceptual shifts rather than a rigid paradigm change.

One of the main problems of Plato's unwritten doctrine has to do with whether his theory of principles has a strictly dualistic or rather a more monistic character. The thesis of this essay is that Plato combines monism and dualism in a particular fashion. Both the dialogues and the testimony of the unwritten doctrine reveal that in Plato's metaphysics the One is the genuinely absolute principle; Plato's second principle, the Many, is not a second absolute - otherwise it would dissolve (...) the very concept of the absolute. Instead, Plato conceives the principle of multiplicity itself as a unity, therefore as in some - in any event ineffable - way as being derived or having emanated from the absolute One. The One itself is wholly transcendent and thus ineffable, knowable neither by reason nor by intellective intuition. Nonetheless, being and knowledge are constituted by the coordination of the One and the Many, for which reason the latter is a principle. Hence, Plato's metaphysics combine a monistic ascent to the absolute with a dualistic derivation of being, a combination made necessary because the One transcends not only all being, but also all knowledge.

By formalizing the problem of mental causation, we first prove rigorously that the premises of the problem are jointly incompatible. Before the background of the formalizations, we clarify and assess the anti-physicalist argument by Scott Sturgeon and the supervenience argument by Jaegwon Kim. We demonstrate that, contrary to what has sometimes been contended, the negation of the non-identity premise of Kim's version of the supervenience argument is not tantamount to the claim that all mental events are identical to physical events, (...) that a premise implicitly invoked by Kim is actually required for the validity of the first stage of his supervenience argument, that precisely this premise makes an epiphenomenalism with respect to mental events an impossible position, and that there are good reasons to believe in the falsity of this implicit premise which in turn shows that Sturgeon's critique of the supervenience argument is substantive.

Just as some illnesses and injuries are worse than others, so some deaths appear to be worse than others. This is so not only for the fairly trivial reason that those deaths that are bad are worse than those deaths that are not bad: less trivially, some bad deaths seem to be worse than other bad deaths. For instance, whereas it may well be bad for an eighty-year-old to die, it is likely to be even worse for a forty-year-old, and (...) still worse for a twenty-year-old. Supposing that the badness of death does indeed vary in this way, what factor or factors does it vary *with*? The example just given indicates that age is one such factor: in particular, the earlier one’s death occurs, the worse it is. For a number of reasons, however, things are more complicated—though not quite as complicated as some philosophers have suggested. (shrink)

A pure time preference is a preference for something to occur at one point in time rather than another, merely because of when it occurs in time. Such preferences are widely regarded as paradigm examples of irrational preferences. However, Rosemary Lowry and Martin Peterson have recently argued that, for instance, a pure time preference to go to the opera tonight rather than next month may be rationally permissible, even if the amounts of intrinsic value realized in both cases are identical. (...) In this reply, we argue that Lowry and Peterson's argument is unsuccessful. (shrink)

In a recent article, Joyce L. Jenkins challenges the common belief that desire satisfactionists are committed to the view that a person's welfare can be affected by posthumous events. Jenkins argues that desire satisfactionists can and should say that posthumous events only play an epistemic role: though such events cannot harm me, they can reveal that I have already been harmed by something else. In this response, however, we show that Jenkins's approach collapses into the view she aims to avoid.

The essay developes the principles of the antique resp. medieval ars memorativa, which was a skill of memorizing large amounts of varying informations. Then the parsonian theory of society is analysed and it is shown, that it is constructed according to the same principles. Hence it follows the thesis, that at least special kinds of sociological (and psychological) theories can be considered as modernized forms of the old ars memorativa. The author defends this thesis against a set of nearby objections. (...) It is not tried to prove the historical truth of thesis, i.e. to show, that the tradition of theoretical literature indeed roots in the tradition of antique resp. medieval ars memorativa. In any case an examination of this question might yield new insight in the prehistory of theoretical thought. (shrink)
