We invite systematic consideration of the metaphors of cycles and circulation as a long-term theme in the history of the life and environmental sciences and medicine. Ubiquitous in ancient religious and philosophical traditions, especially in representing the seasons and the motions of celestial bodies, circles once symbolized perfection. Over the centuries cyclic images in western medicine, natural philosophy, natural history and eventually biology gained independence from cosmology and theology and came to depend less on strictly circular forms. As potent ‘canonical (...) icons’, cycles also interacted with representations of linear and irreversible change, including arrows, arcs, scales, series and trees, as in theories of the Earth and of evolution. In modern times life cycles and reproductive cycles have often been held to characterize life, in some cases especially female life, while human efforts selectively to foster and disrupt these cycles have harnessed their productivity in medicine and agriculture. But strong cyclic metaphors have continued to link physiology and climatology, medicine and economics, and biology and manufacturing, notably through the relations between land, food and population. From the grand nineteenth-century transformations of matter to systems ecology, the circulation of molecules through organic and inorganic compartments has posed the problem of maintaining identity in the face of flux and highlights the seductive ability of cyclic schemes to imply closure where no original state was in fact restored. More concerted attention to cycles and circulation will enrich analyses of the power of metaphors to naturalize understandings of life and their shaping by practical interests and political imaginations.

According to virtue epistemology, the main aim of education is the development of the cognitive character of students (Pritchard, 2014, 2016). Given the proliferation of technological tools such as ChatGPT and other LLMs for solving cognitive tasks, how should educational practices incorporate the use of such tools without undermining the cognitive character of students? Pritchard (2014, 2016) argues that it is possible to properly solve this ‘technology-education tension’ (TET) by combining the virtue epistemology framework with the theory of extended cognition (...) (EXT) (Clark and Chalmers, 1998). He argues that EXT enables us to consider tools as constitutive parts of the students’ cognitive system, thus preserving their cognitive character from technologically induced cognitive diminishment. The first aim of this paper is to show that this solution is not sufficient to solve the TET. Second, I aim to offer a complementary and more encompassing framework of tool-use to address the TET. Then, I apply it to the educational uses of ChatGPT as the most notable example of LLM, although my arguments can be extended to other generative AI systems. To do so, in Sect. 1.1, I present Pritchard’s framework of cognitive character and virtue epistemology applied in education, to which I am committed in this treatment. In Sects. 2 and 3, I respectively illustrate Pritchard’s (2014) solution to the TET, and I highlight the general limitations of his proposal. Thus, in Sect. 4.1 I characterize ChatGPT as a computational cognitive artifact using Fasoli’s (2017, 2018) taxonomy of cognitive artifacts. In Sect. 4.2, I introduce my proposal, which combines Pritchard’s account of virtue epistemology with Fasoli’s (2017, 2018) taxonomy of cognitive artifacts to address the TET. Finally, in Sect. 5.1, I present some epistemically virtuous uses of ChatGPT in educational contexts. To conclude, I argue in favor of a multidisciplinary approach for analyzing educational activities involving AI technologies such as ChatGPT. (shrink)

Historians and philosophers of science have interpreted the taxonomic theory of Carl Linnaeus as an ‘essentialist’, ‘Aristotelian’, or even ‘scholastic’ one. This interpretation is flatly contradicted by what Linnaeus himself had to say about taxonomy in Systema naturae , Fundamenta botanica and Genera plantarum . This paper straightens out some of the more basic misinterpretations by showing that: Linnaeus’s species concept took account of reproductive relations among organisms and was therefore not metaphysical, but biological; Linnaeus did not favour classification by (...) logical division, but criticized it for necessarily failing to represent what he called ‘natural’ genera; Linnaeus’s definitions of ‘natural’ genera and species were not essentialist, but descriptive and polytypic; Linnaeus’s method in establishing ‘natural’ definitions was not deductive, but consisted in an inductive, bottom-up procedure of comparing concrete specimens. The conclusion will discuss the fragmentary and provisional nature of Linnaeus’s ‘natural method’. I will argue in particular that Linnaeus opted for inductive strategies not on abstract epistemological grounds, but in order to confer stability and continuity to the explorative practices of contemporary natural history.

Prompted by recent recognitions of the omnipresence of horizontal gene transfer among microbial species and the associated emphasis on exchange, rather than isolation, as the driving force of evolution, this essay will reflect on hybridization as one of the central concerns of nineteenth-century biology. I will argue that an emphasis on horizontal exchange was already endorsed by ‘biology’ when it came into being around 1800 and was brought to full fruition with the emergence of genetics in 1900. The true revolution (...) in nineteenth-century life sciences, I maintain, consisted in a fundamental shift in ontology, which eroded the boundaries between individual and species, and allowed biologists to move up and down the scale of organic complexity. Life became a property extending both ‘downwards’, to the parts that organisms were composed of, as well as ‘upwards’, to the collective entities constituted by the relations of exchange and interaction that organisms engage in to reproduce. This mode of thinking was crystallized by Gregor Mendel and consolidated in the late nineteenth-century conjunction of biochemistry, microbiology and breeding in agro-industrial settings. This conjunction and its implications are especially exemplified by Wilhelm Johannsen’s and Martinus Beijerinck’s work on pure lines and cultures. An understanding of the subsequent constraints imposed by the evolutionary synthesis of the twentieth century on models of genetic systems may require us to rethink the history of biology and displace Darwin’s theory of natural selection from that history’s centre.

This paper presents and discusses a series of hybridization experiments carried out by Nils Herman Nilsson-Ehle between 1900 and 1907 at a plant breeding station in Svalöf, Sweden. Since the late 1880s, the Svalöf station had been renowned for its ‘scientific’ breeding methods, which basically consisted of an elaborate system of record-keeping through which the offspring of individual plants were traced over generations while being meticulously described. This record system corresponded to a certain breeding technique and certain theoretical convictions . (...) Inspired by Tschermack’s translation of Mendel’s Pisum-paper, Nilsson-Ehle began his experiments in 1900 and published a first, major synthesis of his findings in 1908. If one compares these experiments as documented in the breeding records, with their representations in print, one encounters discrepancies in terms of procedure and presentation of data. This can be explained by the fact that Nilsson-Ehle was obliged to follow the recording and breeding procedures institutionalised at Svalöf, and these procedures, grounded in a taxonomic discourse, left little room for Mendelian hybridisation experiments. The twists and turns that this story takes are analysed in terms of Bachelardian philosophy of science, where the ‘epistemological obstacle’ functions as a central, analytic category. In contrast to Bachelard, however, I will characterise these obstacles as being of an institutional, rather than mental, nature. Thus characterized, moreover, they turn out to have been prerequisites as much as barriers to scientific progress. (shrink)

Many political libertarians argue, or assume, that negative moral duties (duties not to harm others) prevail over positive moral duties (duties to aid others), and that the legal system ought to reflect such pre-eminence. I call into question this strategy for defending a libertarian order. I start by arguing that a successful account of the well-known case of a runaway trolley that is about to kill five innocents unless a passer-by diverts it onto one innocent, killing him, should point to (...) (i) the ex ante advantage to all six of being subject to a policy of redirection of runaway trolleys, and (ii) the causal structure of killing vs. letting-die choices. I then argue that this account of the trolley case entails that legal systems reflecting the relative stringency of negative and positive moral duties should uphold redistributive measures at odds with libertarianism. The assumption that the legal system ought to reflect, through non-causal routes, moral principles and their relative weights leads to either an ideal-theory (in Rawls's sense) assessment of libertarianism or a symbolic account of the relationships between morality and law. Libertarians should undermine this assumption if they hope to offer an all-things-considered case for free markets. (shrink)

The conceptualization of the lifeworld of any species includes a reformation of the matter found in the environment into concepts which make up the species-specific Umwelt. This paper argues that the human agency in conceptualising the Umwelt necessarily transforms what we usually call “nature” into so-called “culture”. Ultimatively, this human activity has two consequences which we cannot escape, but which have an influence not only on our perception of the environment, but also on our theorising about what has been called (...) the “nature-culture divide”, the “semiotic threshold” respectively: First, any environmental perception is at once conceived of in cultural terms. Second, whatever “nature” may be, our including it into the cultural discourse removes it from our immediate cognition. (shrink)

In the United States most people have adopted a worldview based on the core tenets of liberal democracy, capitalism, science, religion and the social sciences. Scientific advances, though, have persuaded many individuals to revise this traditional view and adopt an alternative belief system. Thus some people embrace social democracy, regulated capitalism or a more extreme political philosophy. Others adopt non-theistic religions or break their affiliation with any religion. The latter include naturalists who reject supernatural explanations and take science as the (...) best description of reality. Many people reject the blank slate doctrine and hold that human behaviour results from the interaction of the environment with innate biological factors. (shrink)

Pincione argues that procedural constitutional guarantees of market freedoms best protect individuals from domination. If he is right, Philip Pettit's claim that various forms of state interference with private markets are needed to forestall domination will prove to be unwarranted. Pincione further contends that market freedoms are best protected by procedural rules for political decision-making, as opposed to constitutional guarantees of private property and other substantive rules.Central to his position are claims that the dispersion of economic power precludes domination, and (...) that free entry into markets furthers such dispersion. As against the idea that the state is in a better position to disperse economic power, Pincione argues that the constitutional provisions needed to implement that idea are contestable, and to that extent require interpretive powers that themselves involve domination. Only a constitution that, as a side effect of its procedures for political decision making, generates full private property rights holds out hope of shielding citizens from domination. This is so, because a plurality of suppliers of goods and services is a structural feature of the free market, in a sense of “structural” that matters for measurements of domination based on fairly uncontroversial claims about persons and resources.

Naturalism is a worldview that rejects supernatural events and affirms that a complete account of reality can be given by entities and processes that occur in the natural world. It has a political, moral and spiritual dimension compatible with the Humanist Manifesto. In this paper, I present a description of naturalism based on recent developments in physics and biology. In my view, naturalism is based on scientific realism and accepts indeterminism as postulated by quantum mechanics. Because I cannot prove that (...) only physical entities populate the world, I embrace methodological rather than ontological naturalism. I believe that complex systems exhibit behaviors such as emergence and chaos that can only be explained by non-reductive physicalism. We do not know the origin of life or the universe but there are many plausible theories under investigation. The theory of evolution is the best explanation we have for the amazing variety and complexity in the living world. It is unclear how brain events cause mind events; I suspect that mind is an emergent property of neural circuits in the brain. Religious beliefs have a socialevolutionary origin; I am an agnostic who rejects positive atheism and agrees that science may be compatible with Deism, pantheism and some liberal religions. (shrink)

Studying the Belgian military and foreign policy from 1934 till 1937, one can conclude to the following working hypotheses. The conflict between the King and the Cabinet about the competency over military policy and military command has had a large influence on the acute phase of the Question Royale 1940-1950.The policy of independence of 1936 which has been imputed later on to the King and for which He has been blamed, is rather contained in the military and foreign policy of (...) the successive Belgian governments from 1930 on, inspired by Paul Hymans, minister of foreign affairs at that time.

Let Mn♯ denote the minimal active iterable extender model which has n Woodin cardinals and contains all reals, if it exists, in which case we denote by Mn the class-sized model obtained by iterating the topmost measure of Mn class-many times. We characterize the sets of reals which are Σ1-definable from R over Mn, under the assumption that projective games on reals are determined:1. for even n, Σ1Mn=⅁RΠn+11;2. for odd n, Σ1Mn=⅁RΣn+11.This generalizes a theorem of Martin and Steel for L, (...) that is, the case n=0. As consequences of the proof, we see that determinacy of all projective games with moves in R is equivalent to the statement that Mn♯ exists for all n∈N, and that determinacy of all projective games of length ω2 with moves in N is equivalent to the statement that Mn♯ exists and satisfies AD for all n∈N.

Most attempts at parliamentary reform in Belgium are prompted by the desire to support a Parliament which is being marginalized by political actors such as the government and the parties. These efforts are inspired by traditional constitutional thinking. Initially parliaments were designed as democratie bodies which should challenge the aristocratie government. Nowadays, parliament has quite another function. It has to facilitate the political information and to counteract the incompetence of citizens who are willing but unable to participate in an increasingly (...) complex political system.Reform should aim at restoring the significance ofpublic debates in parliament.In order to be informative these debates should focus on important issues of the political agenda and catch the attention of the general public. Within the constraints of our political system it should be possible to upgrade the early debates on budget allocations and the late debates on the evaluation of public policy effectiveness.

The hypothesis to explain the often puzzling variability of political language in Parliament is that phenotypical elements of political speech such as emotionality, hostility, and oratorical style can be explained by structuralelements, that is by various aspects of the issues under debate.The data led us to criticize the more common cultural hypothesis, which would explain the variations of political language by linking it to the political culture of the members of parliament. As a result the evolutionof political language would be (...) a global one, appearing in all policy domains. This was by no means the case. The evolution of political language between 1950 and 1970 is on the contrary a strongly differentiated one.The structural hypothesis performs much better both for the short- and for the medium-term variations. The expression of hostility during parliamentary debates can be explained satisfactorily by the stakes of the game. The expression of emotion seems to stem both from these stakes and from the level of aggregation of the issue. Finally, various aspects of oratorical style, such as the invocation of values, the principled motivation of proposals and the deductive logic used to legitimize the position taken, all seem to be derived from the level of aggregation and, most of the time, from the ideological contents of the issue as well. As a result we get a profile of political language which is rather tightly controlled by the opportunities and the necessities of the political agenda and much less by all kinds of extraneous factors.

A political science program at the licenciate level is currently offered by the Department of the Political and the Social Sciences at the Universitaire Instelling Antwerpen. It was able to do so with the cooperation of staff-members of other departments and other institutes of the University of Antwerp. The prÓgram is mainly focused on international polities and more specifically on European integration, North-South and East-West relations, as seen from the perspective of Belgian and West-European policy-makers. lts methodology is multidisciplinary and (...) encompasses politological and juridical as well as historical and economical perspectives. In the wake of the first encouraging from the student population, the Department has decided to strenghten further this Political Science branch of its program. It intends to invest more in full-time academie personnel and to add some more theoretical background courses to the present courses which emphasize mainly practical knowledge. Last but not least, it has initiated what it hopes shall be a new tradition of empirical research into the political culture and behaviour of international and supranational policy makers. (shrink)
