Current philosophical reflections on science have departed from mainstream history of science with respect to both methodology and conclusions. The article investigates how different approaches to reconstructing commitments can explain these differences and facilitate a mutual understanding and communication of these two perspectives on science. Translating the differences into problems pertaining to principles of charity, the paper offers a platform for clarification and resolution of the differences between the two perspectives. The outlined contextual approach occupies a middle ground between mainstream (...) history and sociology of science, bracketing questions of rationality, and individual coherence-maximizing, rationality-centered approaches. It can satisfy those, who believe that science is an epistemically privileged endeavor, and its epistemic content should not be neglected when reconstructing the scientists’ positions. It can also satisfy those who hold that it is naive to believe that the immediate context, e.g. the challenges to a theory, the expectations of the author about his audience, etc., does not affect the position a scientist takes. Its theoretical considerations are exemplified with a close study of the debate following the 1672 publication of Newton's theory of light and colours, also offering a novel reading of the development of his methodological views concerning the demonstrativity of the famous crucial experiment. Although we only show the capacity of the framework to analyze a direct controversy, given that it is hard to think about any scientific text as detached from an argumentative context, this approach has the potential to be a general guide for interpretation.

Olaf Müller’s book develops a new case for underdetermination, and, as he is focusing on theories of a ‘limited domain’, this assumes the containability of the theories. First, the paper argues that Müller’s theory of darkness is fundamentally Newtonian, but for Newton’s optical theory the type of theoretical structure Müller adopts is problematic. Second, the paper discusses seventeenth-century challenges to Newton, changes in the proof-structure of Newton’s optical theory, and how these affect Müller’s reconstruction. Müller’s book provides empirically equivalent theories, (...) yet the historical theories were not empirically equivalent, and the same experiments were used to extract different bodies of evidence to rebut the opponent. Third, Goethe’s multi-layered critique of Newton’s experimental proof is investigated, including his developmental account of prismatic colours, the role of experimental series in rejecting Newton’s observations, and his incorporation of the ‘limited domain’ of prismatic colours in a broader framework. Two key elements of Goethe’s method, polarity and strengthening are discussed in contrast to Müller, who only utilises polarity in his account. Finally Neurath’s attempts to come to grips with the optical controversies and the prism-experiments with ‘blurred edges’ are recalled. Müller also discusses in detail some of these experiments and heavily draws on Quine. Neurath developed Duhem’s and Poincaré’s conventionalist insights and had good reasons to be pessimistic about theory-containment. Their differences provide some additions to the history of the Duhem–Quine thesis. (shrink)

Otto Neurath’s thoroughgoing anti-foundationalism is connected to the recognition that protocol sentences are not inviolable, that is they are fallible and their choice cannot be determined: ‘Poincaré, Duhem and others have adequately shown that even if we have agreed on the protocol statements, there is a not limited number of equally applicable, possible systems of hypotheses. We have extended this tenet of the uncertainty of systems of hypotheses to all statements, including protocol statements that are alterable in principle’. Later historiography (...) has called Neurath’s extension of Duhemian holism the Neurath principle. Based on a study of Neurath’s early works on the history of optics, the paper investigates a previously unnoticed influence on the development of this principle, Neurath’s reading of Goethe’s Theory of colours. The historical and polemical parts of Goethe’s tripartite book provided Neurath with ideal examples for the vertical extension of Duhem’s thesis to observation statements. Moreover, Goethe’s critique of the language of science and his views on the theory-ladenness of observation, as well as on the history of science show strong parallels to many of Neurath’s ideas. These demonstrate the existence of surprisingly direct textual links between Romantic views on science and the development of twentieth-century philosophy of science. Neurath’s usage of Goethe’s examples also indicates that the birth of the Neurath principle is more tightly connected to actual scientific practice than to theory-testing, and that by admitting the theory-ladenness of observation reports and fallibility of protocol statements Neurath does not throw empiricism overboard.Keywords: Otto Neurath; J. W. von Goethe; Holism; Theory-ladenness; Duhem-Quine thesis; Romantic science. (shrink)

Taking the real Newtonian colour circle – and not the one Palmer depicts as Newton's – we don't have to wait 300 years for Palmer to say no to the Lockean aperçu about the inverted spectrum. One of the aims of this historical detour is to show that one's commitment about the “topology” of the colour space greatly affects Palmer's argument.

The essay discusses congruency issues in the biosemiotic approach of the Danish biochemist, Jesper Hoffmeyer. The authors understand Hoffmeyer’s anti-reductionistic approach to be similar to Michael Polanyi’s multi-layered ontology, but suggest that the Polanyian approach has fewer handicaps as a model-building enterprise. We offer a historical review of Hoffmeyer’s polarized narrative of 20th century biology and investigate his central thesis that life and semiosis are coextensive. We argue that Hoffmeyer conflates temporal and spatial features of semiotic systems, his account of (...) emergentism is unclear and the relationship between semiotic evolution and punctuated equilibrium is vague, possibly entailing incongruent metaphysical views.

Different approaches to expertise and argumentation are discussed. After introducing the problem of expertise and its present day significance in a historical context, various connections with the study of arguments are highlighted. The need for and potential of argumentation analysis to contribute to existing research in social epistemology, science studies, and cognitive science, is discussed, touching on the problems of reasoning and argumentation, embodiment, tacit knowledge, expert context versus public context, expert disagreement, persuasion versus justification, and argument analysis as meta-expertise. (...) As the arguments used by experts constitute a boundary object, we presume that a dialogue format is suitable to address central problems of the special issue “Rethinking Arguments from Experts”.

A permissivist framework is developed to include images in the reconstruction of the evidential base and of the theoretical content. The paper uses Newton’s optical theory as a case study to discuss mathematical idealizations and depictions of experiments, together with textual correlates of diagrams. Instead of assuming some specific type of theoretical content, focus is on novel traits that are delineable when studying the carriers of a theory. The framework is developed to trace elliptic and ambiguous message design, and utilizes (...) variegated acceptance as an asset. Newton’s resources allowed for various framing modes and reconstructions, entailing various judgements concerning the theoretical content, the evidence base, and Newton’s use of mathematics. Elliptic presentation of the theory’s proof-structure and ambiguities influenced uptake, contributed to the process of opinion-polarization, and the acceptance/rejection of the theory. The study suggests that the analysed carriers of theoretical content have an argumentative function, and one of their uses is to adjust the burden of proof. (shrink)

The essay focuses on controversies where the debated issues are complex, the exchange involves several participants, and extends over long periods. Examples include the Methodenstreit, the Hering-Helmholtz controversy or the debates over Newton’s or Darwin’s views. In these cases controversies lasted for several generations, and polarisation is a recurring trait of the exchanges. The reconstructions and evaluations of the partly polemical exchanges also exhibit heterogeneity and polarisation. Although I pick an early example of the Newtonian controversies, Darwin’s argument in The (...) Origin of Species can also be variously reconstructed. When scientific controversies that involve complex utterances are investigated, a specific problem arises, as in these situations the protagonist presenting a bundle of claims to a non-unified audience cannot fully control meaning-attribution of his utterances, and, given what we know about individual cognition, the more heterogeneous audience he succeeds in persuading, the less clear the meaning becomes. While the acceptance of a position increases potential for action, the growth in consent comes together with a fuzzy content. To problematise the role of polarisation, the significance of this description with respect to knowledge-production is investigated from both an individual and a social epistemological standpoint to answer the question: How is rhetoric epistemic in cases when at least two views on a given issue are seen as persuasively supported by communities? If engaging in a controversy is a means-to-an-end activity aimed at persuasion, directed at achieving attitude-change in recipients, how does the argumentative goal of an individual translate to epistémé in extended scientific controversies?

If any nature of science perspective is to be incorporated in science-related curricula, it is hard to imagine a satisfactory didactic toolkit that neglects the social studies of science, the academic field of study of the institutional structures and networks of science. Knowledge production takes place in a world populated by actors, instruments, and ideas, and various epistemic cultures are responsible for providing the concepts, abstractions, and techniques that slowly trickle down the information pathways to become stabilized in university curricula (...) or ossified in high-school science, losing much of the tacit knowledge along the way that enabled the production of knowledge in the first place. The discussion of the sociology of science and the sociology of scientific knowledge is followed by a short overview of recent approaches in science studies and the studies of expertise. (shrink)

Otto Neurath’s early work on the classification of systems of hypotheses in optics provided some of the key insights of Neurath’s later philosophy of science. The chapter investigates how Neurath developed his theory of theory-classification in response to inconsistencies he stumbled upon while studying the historical theories. Neurath’s empiricism and thoroughgoing fallibilism informed his mapping of the group of theories, locating “elementary notions” of theories and taking into account the “blurred margins” of theories. To replace false dichotomies the project provided (...) a finer-grained analysis of theories and could be utilized to locate unconceived alternatives of a domain. The first sections discuss the close links between Neurath’s optical essays, his notion of an “auxiliary motive,” and his attack on pseudorationalism in the “Lost Wanderers of Descartes” paper. The last sections provide a comparison of the two essays, with an extended table of the elementary notions Neurath listed, and discuss Neurath’s two-tier methodology for historical reconstruction.

ArgumentThe subject of the paper is the shift from an astrology-oriented astronomy towards an allegedly more objective, mathematically grounded approach to astronomy. This shift is illustrated through a close reading of Tycho Brahe's scientific development and the contemporaneous changes in his communicational strategies. Basing the argument on a substantial array of original sources it is claimed that the Danish astronomer developed a new astronomical discourse in pursuit of credibility, giving priority to observational astronomy and natural philosophical questions. The abandonment of (...) astrology in public discourse is primarily explained by Tycho's social position and greater sensibility to controversial issues. Tycho's example suggests that the changes in rhetorical strategies regarding astrology (which happened earlier than changes in astrological belief) should be given more recognition in the history of astronomy.

the Mona Lisa, the Mondscheinsonate, the Chanson d’automne are works of art, the salt shaker on your table, the car in your garage, or the pijamas on your bed are not. the basic question of the metaphysics of works of art is this: what makes a thing a work of art? that is: what sort of property do works of art have in virtue of which they are works of art? or more simply: what sort of property being a work (...) of art is? In this paper we argue that things are works of art in virtue of what they are like, their intrinsic features, that is, in virtue of the fact that they have the perceptual (auditory, visual, etc.) properties they have. In other words: being a work of art supervenes on perceptual-intrinsic features. Currently, this metaphysical view is extremely unpopular within the philosophy of art. It is unpopular because there allegedly exists a knock-down objection to it, the well-known argument from indiscernible counterparts. our thesis implies, among other things, that every perceptual duplicate of a work of art is also a work of art. according to the argument from indiscernible counterparts, however, there could be (or even: there are) indiscernible counterparts such that one of them is a work of art while the other is not. hence things cannot be works of art solely in virtue of what they are like. Our paper divides into three parts. In the first part we state our views. In the second part we defend it against various versions of the argument from indiscernible counterparts. (In doing so our position will become more plausible, we hope). In the final part we provide some meta-reflections on the matter. (shrink)

Here we investigate the classes RCA $^\uparrow_\alpha$ of representable directed cylindric algebras of dimension α introduced by Nemeti[12]. RCA $^\uparrow_\alpha$ can be seen in two different ways: first, as an algebraic counterpart of higher order logics and second, as a cylindric algebraic analogue of Quasi-Projective Relation Algebras. We will give a new, "purely cylindric algebraic" proof for the following theorems of Nemeti: (i) RCA $^\uparrow_\alpha$ is a finitely axiomatizable variety whenever α ≥ 3 is finite and (ii) one can obtain (...) a strong representation theorem for RCA $^\uparrow_\alpha$ if one chooses an appropriate (non-well-founded) set theory as foundation of mathematics. These results provide a purely cylindric algebraic solution for the Finitization Problem (in the sense of [11]) in some non-well-founded set theories. (shrink)

Solar energy has become an integral part of the economy of developed countries, so it is important to monitor the pace of its development, prospects, as well as the largest companies that produce solar panels since the supply of solar energy in a particular country directly depends on them. The study analyzes the shares of Canadian Solar Inc. and First Solar Inc. The purpose of the study is to study the possibility of forecasting the stock price of solar energy companies (...) using neural networks for the purpose of subsequent investment. The recurrent neural network LSTM is used in the article and this approach is based on complexity theory. Machine learning technologies are now being actively implemented in various sectors of the economy and are considered effective. The program used assigns different significance to the data of the last months and the data for the first months of the 1st year. The first year of the last 5 years of the company’s activity is taken as the first year since more distant data no longer have significant significance for the forecast. In the course of the study, a forecast of the stock price of Canadian Solar Inc. and First Solar Inc. for 245 days was obtained. Based on the results obtained, the following conclusions were made: 20 neurons of the network is not enough to make an accurate forecast, but the level of confidence in such a forecast is high enough, neural network forecasts are applicable in investing and are accurate enough to determine medium- and long-term trends, but these forecasts are not applicable for traders. The direction of improving the accuracy of neural network predictions is promising for further research. (shrink)

Continuity as appears to us immediately by intuition differs from its current formalization, the arithmetical continuum or equivalently the set of real numbers used in modern mathematical analysis. Motivated by the known mathematical and physical problems arising from this formalization of the continuum, our aim in this paper is twofold. Firstly, by interpreting Chaitin’s variant of Gödel’s first incompleteness theorem as an inherent uncertainty or fuzziness of the arithmetical continuum, a formal set-theoretic entropy is assigned to the arithmetical continuum. Secondly, (...) by analyzing Noether’s theorem on symmetries and conserved quantities, we argue that whenever the four dimensional space-time continuum containing a single, stationary, asymptotically flat black hole is modeled by the arithmetical continuum in the mathematical formulation of general relativity, the hidden set-theoretic entropy of this latter structure reveals itself as the entropy of the black hole, indicating that this apparently physical quantity might have a pure set-theoretic origin, too.

We will study the class RSA of -dimensional representable substitution algebras. RSA is a sub-reduct of the class of representable cylindric: algebras, and it was an open problem in Andréka [1] that whether RSA can be finitely axiomatized. We will show, that the answer is positive. More concretely, we will prove, that RSA is a finitely axiomatizable quasi-variety. The generated variety is also described. We note that RSA is the algebraic counterpart of a certain proportional multimodal logic and it is (...) related to a natural fragment of first order logic, as well. (shrink)

We study sincere-strategy preference-based approval voting , a system proposed by Brams and Sanver [1] and here adjusted so as to coerce admissibility of the votes , with respect to procedural control. In such control scenarios, an external agent seeks to change the outcome of an election via actions such as adding/deleting/partitioning either candidates or voters. SP-AV combines the voters' preference rankings with their approvals of candidates, where in elections with at least two candidates the voters' approval strategies are adjusted (...) – if needed – to approve of their most-preferred candidate and to disapprove of their least-preferred candidate. This rule coerces admissibility of the votes even in the presence of control actions, and hybridizes, in effect, approval with pluralitiy voting. We prove that this system is computationally resistant to 19 out of 22 types of constructive and destructive control. Thus, SP-AV has more resistances to control than is currently known for any other natural voting system with a polynomial-time winner problem. In particular, SP-AV is the second natural voting system with an easy winner-determination procedure that is known to have full resistance to constructive control, and unlike Copeland voting it in addition displays broad resistance to destructive control.

We study sincere-strategy preference-based approval voting (SP-AV), a system proposed by Brams and Sanver [1] and here adjusted so as to coerce admissibility of the votes (rather than excluding inadmissible votes a priori), with respect to procedural control.

SP-AV combines the voters' preference rankings with their approvals of candidates, where in elections with at least two candidates (...) the voters' approval strategies are adjusted – if needed – to approve of their most-preferred candidate and to disapprove of their least-preferred candidate.

We prove that this system is computationally resistant (i.e., the corresponding control problems are NP-hard) to 19 out of 22 types of constructive and destructive control. Thus, SP-AV has more resistances to control than is currently known for any other natural voting system with a polynomial-time winner problem. In particular, SP-AV is (after Copeland voting, see Faliszewski et al.

Plato claimed that the regular solids are the building blocks of all matter. His views, commonly referred to as the geometric atomistic model, had enormous impact on human thought despite the fact that four of the five Platonic solids can not fill space without gaps. In this paper we quantify these gaps, showing that the errors in Plato’s estimates were quite small. We also develop a mean field approximation to convex honeycombs using a generalized version of Plato’s idea. This approximation (...) not only admits to view convex mosaics in$$d=3$$d=3dimensions as a continuum but we also find that it is quite accurate, showing that Plato’s geometric intuition may have been remarkable.

Deindustrialization is a major burden on workers’ health in many countries, calling for theoretically informed sociological analysis. Here, we present a novel neoclassical sociological synthesis of the lived experience of deindustrialization. We conceptualize industry as a social institution whose disintegration has widespread implications for the social fabric. Combining Durkheimian and Marxian categories, we show that deindustrialization generates ruptures in economic production, which entail job and income loss, increased exploitation, social inequality, and the disruption of services. These ruptures spill over to (...) the field of social reproduction, generating material deprivation, job strain, fatalism, increased domestic workload, anomie, community disintegration, and alienation. These ruptures in social reproduction are sources of psychosocial stress, through which deindustrialization gets embodied as ill health and dysfunctional health behavior. We substantiate this framework through the extensive qualitative thematic analysis of 82 life history interviews in Hungary’s rust belt. (shrink)

The uniform halting problem (UH) can be stated as follows.Give a decision procedure which for any given Turing machine (TM) will decide whether or not it has an immortal instantaneous description (ID).An ID is called immortal if it has no terminal successor. As it is generally the case in the literature (see e.g. Minsky [3, p. 118]) we assume that in an ID the tape must be blank except for some finite numbers of squares. If we remove this restriction the (...) UH becomes the immortality problem (IP). The UH should not be confused with the initialised uniform halting problem (whether or not a TM has an immortal ID when started in a specified state) which can easily be shown to be undecidable (see e.g. Minsky [3, p. 151]).

ABSTRACTThis paper argues that Machiavelli's method, his inductive and comparative use of history and experience for political analysis, and his fashioning of historical-political analysis as ‘science’, played an important and still unrecognised role in his reception in the sixteenth century. It makes the case that Machiavelli's inductive reasoning and stress on historia and experientia offered a model for scientific method that open-minded sixteenth-century scholars, eager to understand, organise and augment human knowledge, could fit to their own epistemology. By focusing on (...) the question of method—a crucial issue for sixteenth-century contemporaries—the paper offers more than a key to the understanding of Machiavelli's positive reception. It also helps in apprehending the crucial importance of Lucretius to Machiavelli's scholarship; the role of the late Renaissance fascination with historia in his reception; and the breadth of appropriation of his method exactly in the decades when anti-Machiavellianism became official politics all over Europe. These claims are sustained through the cases of Machiavelli's early translators and promulgators; the French legal humanists and historiographers; the Swiss, Italian and French scholars engaging with medicine, Paracelsism and astronomy; the authors of political maxims from all over Europe; and finally Francis Bacon.

This is a comprehensive study of the Derveni Papyrus. The papyrus, found in 1962 near Thessaloniki, is not only one of the oldest surviving Greek papyri but is also considered by scholars as a document of primary importance for a better understanding of the religious and philosophical developments in the fifth and fourth centuries BC. Gábor Betegh aims to reconstruct and systematically analyse the different strata of the text and their interrelation by exploring the archaeological context; the interpretation of (...) rituals in the first columns of the text; the Orphic poem commented on by the author of the papyrus; and the cosmological and theological doctrines which emerge from the Derveni author's exegesis of the poem. Betegh discusses the place of the text in the context of late Presocratic philosophy and offers an important preliminary edition of the text of the papyrus with critical apparatus and English translation.

The current confrontation between Russia and Ukraine raises essential problems regarding ethics and laws of war. It also presents an opportunity to compose an ethics case study to analyze the idea of a just war. The present-day war of Russia’s aggression toward Ukraine can hardly be analyzed ethically. We lean back to the seminal ideas of just war theorists to argue that war must be waged in a manner that is consistent with moral and ethical principles, such as proportionality, discrimination, (...) and respect for the rights of non-combatants. This article emphasizes the relationship between war and politics, and the belief that military forces should be used rationally and calculatedly. Wars have influenced the development of the modern world history. The fall of the Soviet Union led to 30 years of peace; however, the ideas of its creators returned to contemporary Russian thinking. We attempt to draw conclusions based on the past to enable conflict to end peacefully and a balance to be restored. (shrink)

The concept of the “End of History” was originally developed by G. W. F. Hegel in the Phenomenology of the spirit in 1806 (Hegel, 2018). The concept can be closely related to a utopia, the completion of the work of philosophers, and the creation of a perfect framework of the finished system of ideas. Hegel had a lot of influence on Western philosophy with the development of this idea and on Marx, who obviously thought of history in dialectic terms. However, (...) he developed the idea of “communism”, which would have been a state of humankind very similar to the concept of Hegel, with no class differences and no opiates of the people—and no place for further development (Marx & Engels, 2002). The “End of History” is based on this theoretical viewpoint that mankind has reached the final and most advanced form of societal development. However, the theorists and their intellectual followers both have to realize a painful way that the phenomenon can only be attained preliminarily. It proves to be a utopia. (shrink)

Recent work in social and cultural studies of science and technology has shown that the ‘epistemic dependence’ of laypeople on experts is not a relation of blind trust, but typically and necessarily involves critical assessment of expert testimonies. Normative epistemologists have suggested a number of criteria, mostly of contextual nature since expert knowledge means restricted cognitive access to some epistemic domain, according to which non-experts can reliably evaluate expert claims; while science studies scholars have concentrated on how laypeople can come (...) to warranted decisions about technical matters on non-technicalgrounds. Instead of addressing the problem transcendentally (how such decisions are possible) or normatively (how such decisions should be reached), this paper contrasts the recommendations available in the literature with the empirical findings of a rough case study concerning the public reaction to the H1N1 vaccine issue. Awareness of how lay people do come to such decisions may inform and refine normative philosophical investigations. (shrink)

The common cause principle says that every correlation is either due to a direct causal effect linking the correlated entities or is brought about by a third factor, a so-called common cause. The principle is of central importance in the philosophy of science, especially in causal explanation, causal modeling and in the foundations of quantum physics. Written for philosophers of science, physicists and statisticians, this book contributes to the debate over the validity of the common cause principle, by proving results (...) that bring to the surface the nature of explanation by common causes. It provides a technical and mathematically rigorous examination of the notion of common cause, providing an analysis not only in terms of classical probability measure spaces, which is typical in the available literature, but in quantum probability theory as well. The authors provide numerous open problems to further the debate and encourage future research in this field. (shrink)

Motivated by the known mathematical and physical problems arising from the current mathematical formalization of the physical spatio-temporal continuum, as a substantial technical clarification of our earlier attempt (Etesi in Found Sci 25:327–340, 2020), the aim in this paper is twofold. Firstly, by interpreting Chaitin’s variant of Gödel’s first incompleteness theorem as an inherent uncertainty or fuzziness present in the set of real numbers, a set-theoretic entropy is assigned to it using the Kullback–Leibler relative entropy of a pair of Riemannian (...) manifolds. Then exploiting the non-negativity of this relative entropy an abstract Hawking-like area theorem is derived. Secondly, by analyzing Noether’s theorem on symmetries and conserved quantities, we argue that whenever the four dimensional space-time continuum containing a single, stationary, asymptotically flat black hole is modeled by the set of real numbers in the mathematical formulation of general relativity, the hidden set-theoretic entropy of this latter structure reveals itself as the entropy of the black hole (proportional to the area of its “instantaneous” event horizon), indicating that this apparently physical quantity might have a pure set-theoretic origin, too.

Based on the existence of polysemy (e.g., lunch can refer to both food and events), it is argued that central tenets of externalist semantics and Fodorian concept atomism, an externalist theory on which words lack semantic structure, are unsound. We evaluate the premise that these arguments rely on—that polysemous words have separate, finer‐grained senses. We survey the evidence across psychology and linguistics and argue that it shows that polysemy does not exist, at least not in this “sense”. The upshot is (...) that if polysemy does not exist, it cannot pose a problem for atomism or externalism. (shrink)

Posicionando-se como “filósofo natural” no tratamento das paixões, Descartes dá início a uma secularização dos afetos ou emoções. Nisso ele é seguido por Spinoza. Em ambos os casos a abordagem filosófica dos afetos tem como consequência desvinculá-los da perspectiva moral, secularizando as emoções: separadas da moral, sua explicação desvincula-se ao mesmo tempo da religião, já que a moral encontra seus fundamentos no deus transcendente. Nesse ponto, Spinoza vai mais longe que Descartes, na secularização das emoções, pois nele o deus é (...) naturalizado, Deus sive natura. A generosidade, por exemplo, não depende mais de um deus dotado de boa vontade, mas sim do exercício natural do homem dotado de razão como parte da Natureza racionalizada. De modo que nem mesmo o amor intelectual de Deus seria substituto do impulso moral religioso: em Spinoza, tal amor, assim como a generosidade e a amizade, inscrevem-se na ordem necessária da natureza, não dependendo de uma vontade livre divina, mas também não se reduzindo a uma vontade humana.

Let be a countable first order structure and endow the universe of with the discrete topology. Then the automorphism group of becomes a topological group. A tuple of automorphisms is defined to be weakly generic iff its diagonal conjugacy class (in the algebraic sense) is dense (in the topological sense) and the ‐orbit of each is finite. Existence of tuples of weakly generic automorphisms are interesting from the point of view of model theory as well as from the point of (...) view of finite combinatorics.The main results of the present work are as follows. In Theorem 2.6 we characterize the existence of tuples of weakly generic automorphisms with the aid of the profinite topology of free groups. In Corollary 2.12 we will show that if has finite topological rank r (and satisfies a further, mild technical condition) then the existence of a weakly generic tuple in implies the existence of weakly generic tuples in for all natural number. Finally, in Theorem 3.2 we show that if is a countable model of an ℵ0‐categorical, simple theory in which all types over the empty set are stationary and has a pair of weakly generic automorphisms then it has tuples of weakly generic automorphisms of arbitrary finite length.At the technical level we will combine elementary investigations about the profinite topology of free groups with the results of [11] about topological ranks of the automorphism groups of some structures.
