This paper studies Sentence 16 of Porphyry’s Pathways to the Intelligible. It is argued that it should be understood against the background of Plotinus’ discussions of the similes of the waxen block and the aviary from Plato’s Theaetetus. The first part of the paper concentrates on Plotinus’ reception of these similes. In the second part of the paper Plotinus’ discussions of the two similes are used to shed light on Sentence 16, in particular on the term προχείρισις. Furthermore it is (...) argued that Porphyry does not reject Plotinus’ claim that, pace Aristotle, intellection does not require imaging. (shrink)

This paper analyzes the historical context and systematic importance of Kant's hypothetical use of reason. It does so by investigating the role of hypotheses in Kant's philosophy of science. We first situate Kant’s account of hypotheses in the context of eighteenth-century German philosophy of science, focusing on the works of Wolff, Meier, and Crusius. We contrast different conceptions of hypotheses of these authors and elucidate the different theories of probability informing them. We then adopt a more systematic perspective to discuss (...) Kant's idea that scientific hypotheses must articulate real possibilities. We argue that Kant's views on the intelligibility of scientific hypotheses constitute a valuable perspective on scientific understanding and the constraints it imposes on scientific rationality.

Kant’s views on animals have received much attention in recent years. According to some, Kant attributed the capacity for objective perceptual awareness to non-human animals, even though he denied that they have concepts. This position is difficult to square with a conceptualist reading of Kant, according to which objective perceptual awareness requires concepts. Others take Kant’s views on animals to imply that the mental life of animals is a blooming, buzzing confusion. In this article I provide a historical reconstruction of (...) Kant’s views on animals, relating them to eighteenth-century debates on animal cognition. I reconstruct the views of Buffon and Reimarus and show that (i) both Buffon and Reimarus adopted a conceptualist position, according to which concepts structure the cognitive experience of adult humans, and (ii) that both described the mental life of animals as a blooming, buzzing confusion. Kant’s position, I argue, is virtually identical to that of Reimarus. Hence Kant’s views on animals support a conceptualist reading of Kant. The article further articulates the historical antecedents of the Kantian idea that concepts structure human cognitive experience and provides a novel account of how the ideas of similarity and difference were conceptualized in eighteenth-century debates on animal cognition.

Within eighteenth-century debates on animal cognition we can distinguish at least three main theoretical positions: (i) Buffon’s mechanism, (ii) Reimarus’ theory of instincts, and (iii) the sensationalism of Condillac and Leroy. In this paper, I adopt a philosophical perspective on this debate and argue that in order to fully understand the justification Buffon, Reimarus, Condillac, and Leroy gave for their respective theories, we must pay special attention to the theoretical virtues these naturalists alluded to while justifying their position. These theoretical (...) virtues have received little to no attention in the literature on eighteenth-century animal cognition, but figure prominently in the justification of the mechanist, instinctive, and sensationalist theories of animal behavior. Through my philosophical study of the role of theoretical virtues in eighteenth-century debates on animal cognition, we obtain a deeper understanding of how theoretical virtues were conceptualized in eighteenth-century science and how they influenced the justification of theories of animal cognition.

Biology in the Critical Philosophy and the Opus postumum Hein van den Berg. Parts of Chap. 2 have been previously published in Hein van den Berg (2011), “ Kant's Conception of Proper Science.” Synthese 183 (1): 7–26. Parts of Chap.

This article explains Kant’s claim that sciences must take, at least as their ideal, the form of a ‘system’. I argue that Kant’s notion of systematicity can be understood against the background of de Jong & Betti’s Classical Model of Science (2010) and the writings of Georg Friedrich Meier and Johann Heinrich Lambert. According to my interpretation, Meier, Lambert, and Kant accepted an axiomatic idea of science, articulated by the Classical Model, which elucidates their conceptions of systematicity. I show that (...) Kant’s critique of the mathematical method is compatible with his adherence to this axiomatic conception of science. I further show that systematicity furthers traditionally accepted logical ideals of scientific knowledge, which explains why Meier and Kant think that sciences must be ‘systematic’. (shrink)

In the present paper I investigate the role that analogy plays in eighteenth-century biology and in Kant’s philosophy of biology. I will argue that according to Kant, biology, as it was practiced in the eighteenth century, is fundamentally based on analogical reflection. However, precisely because biology is based on analogical reflection, biology cannot be a proper science. I provide two arguments for this interpretation. First, I argue that although analogical reflection is, according to Kant, necessary to comprehend the nature of (...) organisms, it is also necessarily insufficient to fully comprehend the nature of organisms. The upshot of this argument is that for Kant our understanding of organisms is necessarily limited. Second, I argue that Kant did not take biology to be a proper science because biology was based on analogical arguments. I show that Kant stemmed from a philosophical tradition that did not assign analogical arguments an important justificatory role in natural science. Analogy, according to this conception, does not provide us with apodictically certain cognition. Hence, sciences based on analogical arguments cannot constitute proper sciences. (shrink)

Kant’s teleology as presented in the Critique of Judgment is commonly interpreted in relation to the late eighteenth-century biological research of Johann Friedrich Blumenbach. In the present paper, I show that this interpretative perspective is incomplete. Understanding Kant’s views on teleology and biology requires a consideration of the teleological and biological views of Christian Wolff and his rationalist successors. By reconstructing the Wolffian roots of Kant’s teleology, I identify several little known sources of Kant’s views on biology. I argue that (...) one of Kant’s main contributions to eighteenth-century debates on biology consisted in demarcating biology from metaphysics. Kant rejected Wolffian views on the hierarchy of sciences, according to which propositions specifying the functions of organisms are derived from theological truths. In addition, Kant argued that organic self-organization necessitates a teleological description in order to show that self-organization does not support materialism. By demarcating biology and metaphysics, Kant made a small yet important contribution to establishing biology as a science. (shrink)

Kant is well known for his restrictive conception of proper science. In the present paper I will try to explain why Kant adopted this conception. I will identify three core conditions which Kant thinks a proper science must satisfy: systematicity, objective grounding, and apodictic certainty. These conditions conform to conditions codified in the Classical Model of Science. Kant’s infamous claim that any proper natural science must be mathematical should be understood on the basis of these conditions. In order to substantiate (...) this reading, I will show that only in this way it can be explained why Kant thought (1) that mathematics has a particular foundational function with respect to the natural sciences and (2) as such secures their scientific status.

Recently, the second author, Briseid, and Safarik introduced nonstandard Dialectica, a functional interpretation capable of eliminating instances of familiar principles of nonstandard arithmetic—including overspill, underspill, and generalizations to higher types—from proofs. We show that the properties of this interpretation are mirrored by first-order logic in a constructive sheaf model of nonstandard arithmetic due to Moerdijk, later developed by Palmgren, and draw some new connections between nonstandard principles and principles that are rejected by strict constructivism. Furthermore, we introduce a variant of (...) the Diller–Nahm interpretation with two different kinds of quantifiers, similar to Hernest’s light Dialectica interpretation, and show that one can obtain nonstandard Dialectica by weakening the computational content of the existential quantifiers—a process called herbrandization. We also define a constructive sheaf model mirroring this new functional interpretation, and show that the process of herbrandization has a clear meaning in terms of these sheaf models. (shrink)

In this paper, we analyse conceptions of induction and certainty in Wolff and Crusius, highlighting their competing conceptions of physics. We discuss (i) the perspective of Wolff, who assigned induction an important role in physics, but argued that physics should be an axiomatic science containing certain statements, and (ii) the perspective of Crusius, who adopted parts of the ideal of axiomatic physics but criticized the scope of Wolff’s ideal of certain science. Against interpretations that take Wolff’s proofs in physics to (...) be based on empirical statements that are probable, we show how inductively established statements, coupled with assumptions concerning the uniformity of nature, can be certain according to Wolff. We examine Crusius’ little known work on physics and show that he attacked Wolff, arguing that many statements of physics are probable. We provide a discussion of the reception of methodological rules similar to Newton’s Regulae Philosophandi, discussing different interpretations of such rules. We conclude by briefly hinting at how the debate between Wolff and Crusius provides historical context for understanding Kant’s philosophy of natural science. (shrink)

Within moral psychology, theories focusing on the conceptualization and empirical measurement of people’s morality in terms of general moral values –such as Moral Foundation Theory- (implicitly) assume general moral values to be relevant concepts for the explanation and prediction of behavior in everyday life. However, a solid theoretical and empirical foundation for this idea remains work in progress. In this study we explore this relationship between general moral values and daily life behavior through a conceptual analysis and an empirical study. (...) Our conceptual analysis of the moral value-moral behavior relationship suggests that the effect of a generally endorsed moral value on moral behavior is highly context dependent. It requires the manifestation of several phases of moral decision-making, each influenced by many contextual factors. We expect that this renders the empirical relationship between generic moral values and people’s concrete moral behavior indeterminate. Subsequently, we empirically investigate this relationship in three different studies. We relate two different measures of general moral values -the Moral Foundation Questionnaire and the Morality As Cooperation Questionnaire- to a broad set of self-reported morally relevant daily life behaviors (including adherence to COVID-19 measures and participation in voluntary work). Our empirical results are in line with the expectations derived from our conceptual analysis: the considered general moral values are poor predictors of the selected daily life behaviors. Furthermore, moral values that were tailored to the specific context of the behavior showed to be somewhat stronger predictors. Together with the insights derived from our conceptual analysis, this indicates the relevance of the contextual nature of moral decision-making as a possible explanation for the poor predictive value of general moral values. Our findings suggest that the investigation of morality’s influence on behavior by expressing and measuring it in terms of general moral values may need revision. (shrink)

This paper analyzes Immanuel Kant’s views on mechanical explanation on the basis of Christian Wolff’s idea of scientific demonstration. Kant takes mechanical explanations to explain properties of wholes in terms of their parts. I reconstruct the nature of such explanations by showing how part-whole conceptualizations in Wolff’s logic and metaphysics shape the ideal of a proper and explanatory scientific demonstration. This logico-philosophical background elucidates why Kant construes mechanical explanations as ideal explanations of nature.

Using Althaus-Reid’s Indecent Theology as a methodology, this article contributes to reflections on the contextuality and physical dimension of Dutch theology: its relation to the Protestant white bodies of its practitioners and its support of and contributions to colonial power and colonial racializing discourse. We do this in a context of a ‘return to decency’ in political discourse in which ‘our’ Calvinist roots are evoked to construct a ‘shared’ past. Using two case studies, we analyse how the in/decent is constructed (...) in the Netherlands. As secularism is more ‘vanilla’ and Calvinism more indecent than is usually assumed, engagement with indecent texts and untidy roots of Calvinism is needed to re-member both the violent character of Calvinist hermeneutics, as well as its potential for indecent readings.

In this essay Luc Van den Berge and Stefan Ramaekers take the idea of “scientific parenting” as an example of ambiguities that are typical of our late-modern condition. On the one hand, parenting seems like a natural thing to do, which makes “scientific parenting” sound like an oxymoron; on the other hand, a disengaged stance informed by the latest scientific findings is uncritically demanded of parents, as such an approach is conceived of as a panacea. Instead of taking sides in (...) this discussion, the authors seek a way to make sense of it, drawing upon the work of Charles Taylor, who offers a striking account of our contingent modern condition as well as of our ontological human constitution. They focus particularly on two examples Taylor gives where the contingent self-understanding does not coincide with our timeless human features. This opens a space for what might be considered paradoxes in our late-modern Western culture. This essay thus confronts Taylor's philosophy with the new parenting discourse to reveal how our moral horizons have evolved. Following this approach, the authors both expand on Taylor's thinking about our late modernity and at the same time try to assess the new scientific parenting discourse. (shrink)

A nucleus is an operation on the collection of truth values which, like double negation in intuitionistic logic, is monotone, inflationary, idempotent and commutes with conjunction. Any nucleus determines a proof-theoretic translation of intuitionistic logic into itself by applying it to atomic formulas, disjunctions and existentially quantified subformulas, as in the Gödel–Gentzen negative translation. Here we show that there exists a similar translation of intuitionistic logic into itself which is more in the spirit of Kuroda’s negative translation. The key is (...) to apply the nucleus not only to the entire formula and universally quantified subformulas, but to conclusions of implications as well. (shrink)

How can we best reconstruct the origin of a notion, its development, and possible spread to multiple fields? We present a pilot study on the spread of the notion of conceptual scheme. Though the notion is philosophically important, its origin, development, and spread are unclear. Several purely qualitative and competing historical hypotheses have been offered, which rely on disconnected disciplinary traditions, and have never been tested all at once in a single comprehensive investigation fitting the scope of its subject matter. (...) As a step toward such an investigation, we trace the use of the bigram “conceptual scheme” in about 42,000 US journal articles in social sciences from 1888-1959 by using a novel method combining a quantitative procedure aided by basic computational techniques with qualitative elements informed by Betti and van den Berg (2014)’s ‘model approach to the history of ideas’.

In their introduction to the recent excellent volume Plato & Hesiod, the editors G.R. Boys-Stones and J.H. Haubold observe that when we think about the problematic relationship between Plato and the poets, we tend to narrow this down to that between Plato and Homer. Hesiod is practically ignored. Unjustly so, the editors argue. Hesiod provides a good opportunity to start thinking more broadly about Plato's interaction with poets and poetry, not in the least because the ‘second poet’ of Greece represents (...) a different type of poetry from Homer's heroic epics, that of didactic poetry. What goes for Plato and Hesiod goes for Proclus and Hesiod. Proclus , the productive head of the Neoplatonic school in Athens, took a great interest in poetry to which he was far more positively disposed than Plato had ever been. He wrote, for example, two lengthy treatises in reaction to Socrates' devastating criticism of poetry in the Republic as part of his commentary on that work in which he tries to keep the poets within the Platonic pale. This intriguing aspect of Proclus' thought has, as one might expect, not failed to attract scholarly attention. In Proclus' case too, however, discussions tend to concentrate on his attitude towards Homer . To some extent this is only to be expected, since much of the discussion in the Commentary on the Republic centres on passages from Homer. Proclus did not, however, disregard Hesiod: we still possess his scholia on the Works and Days, now available in a recent edition by Patrizia Marzillo. (shrink)

HENDRIK VAN DEN BERG argues that Rand's claim that evidence of capitalism's success is "incontrovertible" cannot be confirmed using familiar annual GDP per capita figures. This article argues that annual GDP per capita cannot logically represent individual welfare because it measures an annual income flow while individuals judge their welfare by their lifetime income. Data are available to measure an economy's capacity to enhance individual lifetime welfare. Not only does this measure come closer to Rand's focus on the individual, (...) it also suggests that the past 200 years of capitalist development have raised individual welfare even more than the familiar, but misleading, annual GDP measures show.

This paper argues that pre‐departure language requirements for family reunification are unjustified. Such requirements are assumed to safeguard (1) the non‐instrumental cultural interests of citizens of the receiving society and (2) the instrumental language interests of both citizens and immigrants, for democratic life and political participation. The paper explores nationalist and multiculturalist arguments for implementing post‐arrival integration to ensure a shared public language but contends that such arguments cannot justify pre‐departure language requirements. In addition, instrumental language interests for democratic political (...) life fall empirically short and place undue burdens on immigrants. The case of family reunification poses a unique moral problem, given the vital interest in living with one's family. The paper argues that the linguistic interests of the receiving state, in general, do not outweigh the claim to family reunification. (shrink)

The publication of Frank Furedi's Paranoid Parenting in 2001 was trend-setting in the sense that it addresses parents directly in a way that is intended to be both critical and supportive, by helping parents to look through a sociological lens at their alleged predicament. Furedi's hope is that this will lead to the restoration of parental self-confidence, which he claims to be sorely lacking in contemporary (Western?) society. I argue that such a project would be more likely to succeed if (...) one were to hold a less dim view of the way both parents and other individuals are connected with their own society. By introducing a cultural-hermeneutical perspective on human agency, based on a specific reading of Heidegger and Taylor, I suggest a more constructive way to reconnect parents with the ongoing conversations in their communities and to conceptualise parenting support.

The nonstandard stroboscopy method links discrete-time ordinary difference equations of first-order and continuous-time, ordinary differential equations of first order. We extend this method to the second order, and also to an elementary, yet general class of partial difference/differential equations, both of first and second order. We thus obtain straightforward discretizations and continuizations, even avoiding change of variables. In fact, we create intermediary objects: partial difference equations with S-continuous solutions, which have both discrete and continuous properties.

We propose an extension of Aczel's constructive set theory CZF by an axiom for inductive types and a choice principle, and show that this extension has the following properties: it is interpretable in Martin-Löf's type theory. In addition, it is strong enough to prove the Set Compactness theorem and the results in formal topology which make use of this theorem. Moreover, it is stable under the standard constructions from algebraic set theory, namely exact completion, realizability models, forcing as well as (...) more general sheaf extensions. As a result, methods from our earlier work can be applied to show that this extension satisfies various derived rules, such as a derived compactness rule for Cantor space and a derived continuity rule for Baire space. Finally, we show that this extension is robust in the sense that it is also reflected by the model constructions from algebraic set theory just mentioned. (shrink)

We propose a new method for the history of ideas that has none of the shortcomings so often ascribed to this approach. We call this method the model approach to the history of ideas. We argue that any adequately developed and implementable method to trace continuities in the history of human thought, or concept drift, will require that historians use explicit interpretive conceptual frameworks. We call these frameworks models. We argue that models enhance the comprehensibility of historical texts, and provide (...) historians of ideas with a method that, unlike existing approaches, is susceptible neither to common holistic criticisms nor to Skinner's objections that the history of ideas yields arbitrary and biased reconstructions. To illustrate our proposal, we discuss the so-called Classical Model of Science and draw upon work in computer science and cognitive psychology. (shrink)

People often say that humans are omnivores in order to justify eating meat as normal and veganism as abnormal. The is one of the arguments that vegetarians and vegans encounter when meat-eaters try to defend the moral acceptability of body parts on their plate. When responding to this argument, the position of the vegan is similar to the atheist who time and again is confronted with the same fallacious arguments in support of the existence of god(s). Veganism and atheism are (...) both ethical default positions. Similarly, not killing other people is also a default position. (shrink)

The monetary theories in Philip Cantillon's The Analysis of Trade (1759) differ in important respects from those found in Richard Cantillon's much more famous Essai sur la nature de Commerce en general (1759). Contrary to the received opinion that the Analysis was a poor translation of the Essai, it is argued in this paper that many of these differences are due to the fact that Philip based his book on an earlier draft of his cousin's great work. Comparisons between the (...) two texts allow us to assess, for the first time, how Richard Cantillon's developed his ideas on the quantity theory of money, the price-specie-flow mechanism and the determination of the interest rate.

In this paper I provide some critical comments on Schulting’s Kant’s Radical Subjectivism (2017). I will focus on two aspects of Schulting’s reading of Kant: his reading of Kant as a coherentist and his reading of Kant as a conceptualist. I will argue that it is not clear whether Kant accepts a form of coherentism and I will discuss reflections of Kant on animals that may be difficult to square with a conceptualist reading of Kant.

Social media makes an important contribution to a rapidly changing world in which various domains of meaning are described anew. The evolving nature and dynamic character of social media therefore provides for a rich praxis terrain with which to interact from a practical theological orientation. More specifically associated with the theme of this contribution, the social media sphere also provides an excellent space not only to rethink but also to reenact expressions of dignity in society. The research is facilitated from (...) a practical theological orientation, with particular focus on a normative dimension as embodied in aspects of dignity. Through the use of an interdisciplinary approach and methodology, some contours of dignity specifically associated with South African politics as well as the so-called Charlie Hebdo attacks in 2015 in Paris expressed on the social media platform, Twitter, are described and discussed. From this empirical analysis, description and discussion, a practical theological reflection is offered in which aspects of dignity associated with a normativity function are described. Some practical theological perspectives contributing to future relevant tweeting on dignity are also formulated and provided in conclusion. (shrink)

Within the empirical study of moral decision making, people’s morality is often identified by measuring general moral values through a questionnaire, such as the Moral Foundations Questionnaire provided by Moral Foundations Theory (MFT). However, the success of these moral values in predicting people’s behaviour has been disappointing. The general and context-free manner in which such approaches measure moral values and people’s moral identity seems crucial in this respect. Yet, little research has been done into the underlying notion of self. This (...) article aims to fill this gap. Taking a phenomenological approach and focusing on MFT, we examine the concept of moral self that MFT assumes and present an improved concept of moral self for the empirical study of morality. First, we show that MFT adopts an essentialist concept of moral self, consisting of stable moral traits. Then, we argue that such a notion is unable to grasp the dynamical and context sensitive aspects of the moral self. We submit that Ricoeur’s narrative notion of identity, a self that reinterprets itself in every decision situation through self-narrative, is a viable alternative since it is able to incorporate context sensitivity and change, while maintaining a persisting moral identity. Finally, we argue that this narrative concept of moral self implies measuring people’s morality in a more exploratory fashion within a delineated context. (shrink)

In this paper we investigate Accardi's claim that the "quantum paradoxes" have their roots in probability theory and that, in particular, they can be evaded by giving up Bayes' rule, concerning the relation between composite and conditional probabilities. We reach the conclusion that, although it may be possible to give up Bayes' rule and define conditional probabilities differently, this contributes nothing to solving the philosophical problems which surround quantum mechanics.

This article argues that the social constructivist paradigm falls into the same dualistic trap as biological essentialism when attempting to respond to questions of gender and sexuality. I argue that social constructivism, like biological determinism, presumes a ‘split’ world, where subjective lived experiences are separated from the world of socio-cultural forces. Following a phenomenological approach, grounded in Merleau-Ponty’s ontological view of the body, this article attempts to move beyond the dualistic metadiscourses of social constructivism in maintaining that identity is a (...) fully embodied process. I see gender and sexuality as necessarily embodied and corporeally constituted. In the light of this, I propose an understanding of gender and sexuality that focuses on the centrality of the body as open project. This approach sees gender and sexuality as embodied processes that are enmeshed with the complex fabric of lived everyday experiences and concurrent socio-cultural and historical processes. Drawing on real-life examples, I conclude that gender and sexual embodiment are not one-dimensional according to a binary system of male versus female. Rather, given the documented experience of the indeterminacy and ambiguity of human existence, there are a variety of possible embodiments of humankind. (shrink)

We show that Martin Hyland's effective topos can be exhibited as the homotopy category of a path category EFF. Path categories are categories of fibrant objects in the sense of Brown satisfying two additional properties and as such provide a context in which one can interpret many notions from homotopy theory and Homotopy Type Theory. Within the path category EFF one can identify a class of discrete fibrations which is closed under push forward along arbitrary fibrations (in other words, this (...) class is polymorphic or closed under impredicative quantification) and satisfies propositional resizing. This class does not have a univalent representation, but if one restricts to those discrete fibrations whose fibres are propositions in the sense of Homotopy Type Theory, then it does. This means that, modulo the usual coherence problems, it can be seen as a model of the Calculus of Constructions with a univalent type of propositions. We will also build a more complicated path category in which the class of discrete fibrations whose fibres are sets in the sense of Homotopy Type Theory has a univalent representation, which means that this will be a model of the Calculus of Constructions with a univalent type of sets.

Chervenak and McCullough, authors of the most acknowledged ethical framework for maternal–fetal surgery, rely on the ‘ethical–obstetrical’ concept of the fetus as a patient in order to determine what is morally owed to fetuses by both physicians and the women who gestate them in the context of prenatal surgery. In this article, we reconstruct the argumentative structure of their framework and present an internal criticism. First, we analyse the justificatory arguments put forward by the authors regarding the moral status of (...) the fetus qua patient. Second, we discuss the internal coherence and consistency of the moral obligations those authors derive from that concept. We claim that some of the dilemmas their approach is purported to avoid, such as the debate about the independent moral status of the fetus, and the foundation of the moral obligations of pregnant women (towards the fetuses they gestate) are not, all things considered, avoided. Chervenak and McCullough construct the obligations of physicians as obligations towards entities with equal moral status. But, at the same time, they assume that the woman has an independent moral status while the moral status of the fetus is dependent on the decision of the woman to present it to a physician for care. According to the logic of their own argumentation, Chervenak and McCullough implicitly admit a different moral status of the woman and the fetus, which will lead to different ascription of duties of the physician than those they ascribed.

This article focuses on maternal-fetal surgery (MFS) and on the concept of clinical equipoise that is a widely accepted requirement for conducting randomized controlled trials (RCT). There are at least three reasons why equipoise is unsuitable for MFS. First, the concept is based on a misconception about the nature of clinical research and the status of research subjects. Second, given that it is not clear who the research subject/s in MFS is/are, if clinical equipoise is to be used as a (...) criterion to test the ethical appropriateness of RCT, its meaning should be unambiguous. Third, because of the multidisciplinary character of MFS, it is not clear who should be in equipoise. As a result, we lack an adequate criterion for the ethical review of MFS protocols. In our account, which is based on Chervenak and McCullough's seminal work in the field of obstetric ethics, equipoise is abandoned. and RCT involving MFS can be ethically initiated when a multidisciplinary ethics review board (ERB), having an evidence-based assessment of the risks involved, is convinced that the value of answering the research hypothesis, for the sake of the health interests of future pregnant women carrying fetuses with certain congenital birth defects, justifies the actual risks research participants might suffer within a set limit of low/manageable.
