The aim of this research was to determine the degree to which undergraduate students’ learning approach, academic achievement and satisfaction were determined by the combination of an intrapersonal factor (self-regulation) and a interpersonal factor (contextual or regulatory teaching). The hypothesis proposed that greater combined regulation (internal and external) would be accompanied by more of a deep approach to learning, more satisfaction and higher achievement, while a lower level of combined regulation would determine a surface approach, less satisfaction and lower achievement. (...) Within an ex post facto design by selection, 1036 university students completed validated questionnaires using an online tool. Several multivariate analyses were conducted. Results showed that the combination of self-regulation and external regulation can be ordered as levels along a five-point scale or heuristic. These levels linearly determine type of learning approach, academic achievement and satisfaction. Implications are established for quality and improvement of the teaching and learning process at university. (shrink)

The combination of student Self-Regulation (SR) and the context of Regulatory Teaching (RT), each in varying degree, has recently been demonstrated to have effects on achievement emotions, factors and symptoms of stress, and coping strategies. The aim of the present research study is to verify its possible further effects, on academic behavioral confidence and procrastination. A total of 1193 university students completed validated online questionnaires with regard to specific subjects in their degree program. Using an ex post facto design, multivariate (...) analyses and structural equation modeling (SEM) were carried out in order to test the relationships predicted by the model. SR and RT had a significant joint effect in determining the degree of academic behavioral confidence and of procrastination. Academic behavioral confidence also significantly predicted reasons for procrastinating, and these in turn predicted activities of procrastination. Conclusions are discussed, insisting on the combined weight of the two variables in determining academic behavioral confidence, reasons for procrastinating and activities subject to procrastination, in university students. Implications for guidance and educational support of university students and teachers are analyzed. (shrink)

Théologien, historien, philosophe, sociologue et homme politique libéral, Ernst Troeltsch (1865-1923) fait partie du groupe des théologiens protestants allemands appelé " Ecole de l'histoire des religions ". Revendiquant l'héritage de Kant et de Schleiermacher, proche de Max Weber et du néo-kantisme de l'Ecole de Bade, Troeltsch est le théoricien classique du néo-protestantisme. Surtout connu en France comme sociologue de la religion, il est redécouvert aujourd'hui comme philosophe et théologien, éclipsé un temps par Barth, l'existentialisme et Heidegger. Les huit essais rassemblés (...) ici sont écrits à l'horizon d'une réflexion sur le religieux marquée par les sciences humaines et sociales et par une conscience accusée de la pluralité des formes de la religion. Troeltsch y dessine un programme qui inscrit délibérément la théologie dans une perspective historique, tout en s'efforçant d'articuler approche empirique et interrogation touchant les jugements de valeur. Il récuse ainsi toute tentative pour faire valoir un domaine théologique réservé : non seulement le christianisme n'est pas la religion dans sa forme achevée ou " absolue ", mais les tentatives pour déterminer une " essence " du christianisme par-delà ses inscriptions socioculturelles diverses devront également être refusées. En désenclavant la réflexion théologique, Troeltsch oblige à redéfinir son objet et son statut : elle ne sera plus explicitation du croire, mais devra esquisser une théorie du christianisme précisant le statut, la fonction et les limites du religieux dans une modernité marquée par la diversification des instances de rationalisation et de légitimité. Ce faisant, son propos tranche avec les discours théologiques dominants dans la seconde moitié du XXe siècle, tant en protestantisme qu'en catholicisme. Et il ouvre à nouveau la question d'une pertinence sociale et culturelle du religieux et du théologique. A l'heure où les paradigmes modernes se trouvent en profonde interrogation sur eux-mêmes et où la question religieuse fait retour - peut-être pour le meilleur mais souvent pour le pire -, la lecture de Troeltsch peut apporter une contribution bienvenue à un ensemble de questions parmi les plus centrales de notre temps. Publiés pour la première fois en français, les textes présentés ici sont accompagnés d'un important appareil de commentaires historiques aidant le lecteur à reconstituer le contexte et la genèse des débats en cause.

An analysis is briefly presented of the possible causes of the failure of stochastic electrodynamics (SED) when applied to systems with nonlinear forces, on the basis that the main principles of the theory are correct. In light of this analysis, an alternative approach to the theory is discussed, whose postulates allow to establish contact with quantum mechanics in a natural way. The ensuing theory, linear SED, confirms the essential role of the vacuum–particle interaction as the source of quantum phenomena.

The SRL vs. ERL theory has shown that the combination of levels of student self-regulation and regulation from the teaching context produces linear effects on achievement emotions and coping strategies. However, a similar effect on stress factors and symptoms of university students has not yet been demonstrated. The aim of this study was to test this prediction. It was hypothesized that the level of student self-regulation (low/medium/high), in interaction with the level of external regulation from teaching (low/medium/high), would also produce (...) a linear effect on stress factors and symptoms of university students. A total of 527 undergraduate students completed validated questionnaires about self-regulation, regulatory teaching, stress factors and symptoms. Using an ex post facto design by selection, ANOVAs and MANOVAs (3 x 3; 5 x 1; 5 x 2) were carried out. The results confirmed that the level of self-regulation and the level of regulatory teaching jointly determined the level of stress factors and symptoms of university students. Once again, a five-level heuristic of possible combinations was configured to jointly determined university students’ level of academic stress. We concluded that the combination of different levels of student regulation levels and regulation from teaching process jointly determines university students’ level of academic stress. The implications for university students’ emotional health, stress prevention and well-being are established. (shrink)

We formulate from first principles a theory of stochastic processes in configuration space. The fundamental equations of the theory are an equation of motion which generalizes Newton's second law and an equation which expresses the condition of conservation of matter. Two types of stochastic motion are possible, both described by the same general equations, but leading in one case to classical Brownian motion behavior and in the other to quantum mechanical behavior. The Schrödinger equation, which is derived here with no (...) further assumption, is thus shown to describe a specific stochastic process. It is explicitly shown that only in the quantum mechanical process does the superposition of probability amplitudes give rise to interference phenomena; moreover, the presence of dissipative forces in the Brownian motion equations invalidates the superposition principle. At no point are any special assumptions made concerning the physical nature of the underlying stochastic medium, although some suggestions are discussed in the last section. (shrink)

We discuss the main results of Linear Stochastic Electrodynamics, starting from a reformulation of its basic assumptions. This theory shares with Stochastic Electrodynamics the core assumption that quantization comes about from the permanent interaction between matter and the vacuum radiation field, but it departs from it when it comes to considering the effect that this interaction has on the statistical properties of the nearby field. In the transition to the quantum regime, correlations between field modes of well-defined characteristic frequencies arise, (...) which coincide with the transition frequencies of quantum mechanics and are therefore directly related with the energy quantization. The Heisenberg equations of motion of (non-relativistic) quantum electrodynamics are thus obtained. After a detailed consideration of the significance of the approximations made, we present a discussion on some of the most delicate or controversial features of quantum mechanics from the perspective provided by the present theory.

A ces mérites, on ajoutera une curiosité insatiable, un goût prononcé pour l'échange et le débat, un refus distingué de l'académisme, un sens exigeant de l'amitié et une méfiance profônde pour les adjectifs... C'est cet édifice de qualités que les élèves, collègues et amis de Michel Troper sont heureux de célébrer en lui offrant ces Mélanges. (shrink)

The aim of the present paper is to provide a logical reconstruction of the Marxian Theory of Value. This reconstruction is based upon the concept of abstract as opposed to that of homogeneous labor.labour is a social relation that holds in a market economy, whenever the profit rate is uniform; it consists in a comparison of the different labors through the exchange relationship. The author proved in a different place that there exists a mathematical representation of abstract labor which is (...) unique up to similarity transformations. The existence of this function -- which is none other than the value function -- is the basis of the present axiomatization, which includes detailed reconstructions of two of the most important models of the theory.

The Value of the Emotional Knowledge Emotional knowledge is a form of self-knowledge which holds great interest for ordinary individuals. It is not obtained by any obligation but rather because we think it is crucial to obtain. In this article it is a matter of demonstrating that emotional knowledge holds an instrumental and a prudential value. By arguing that it can allow a control over our emotions, I shall maintain that emotional knowledge affects individual marginalization or acceptance in society. In (...) addition, this type of knowledge is revealing of our personality by allowing us to identify our affective identities. Finally, I shall defend the idea that emotional knowledge contributes to the conduct of a good life. As such, my hypothesis could be viewed as incompatible with widespread ideas, according to which the knowledge of our own emotions can trigger negative emotional states, e.g. mental rumination, anxiety, that do not contribute to our well-being.

The following analysis consider one of the most recognized movies in the history of Cinema, “A Clockwork Orange”, identifying and examining the elements of the narration, which characterize it as a satire. However, this assertion lead to ask, which type of satire represent the Film. To structure these characterizations will be allude the Satire Theory of Friedrich Schiller, which works to delimitate not only the satirical elements of the story, but the mode the movie takes to become a critic to (...) the society. This will show how the Movie operate as a moralizing reflection, whose originality lies in the employment of the Satire to carry out this reflection. (shrink)

The state of computing science and, particularly, software engineering and knowledge engineering is generally considered immature. The best starting point for achieving a mature engineering discipline is a solid scientific theory, and the primary reason behind the immaturity in these fields is precisely that computing science still has no such agreed upon underlying theory. As theories in other fields of science do, this paper formally establishes the fundamental elements and postulates making up a first attempt at a theory in this (...) field, considering the features and peculiarities of computing science. The fundamental elements of this approach are informons and holons, and it is a general and comprehensive theory of software engineering and knowledge engineering that related disciplines (e.g., information systems) can particularise and/or extend to take benefit from it (Lakatos’ concepts of core theory and protective belt theories).

A theory of collective violence must explain both why it is collective and why it is violent. Whereas my earlier work addresses the question of why collective violence is violent, here I apply and extend Donald Black's theory of partisanship to the question of why violence collectivizes. I propose in general that the collectivization of violence is a direct function of strong partisanship. Strong partisanship arises when third parties support one side against the other and are solidary among themselves. Such (...) support occurs when third parties are socially close to one side and remote from the other and when one side has more social status than the other. Third parties are solidary when they are intimate, culturally homogeneous, and interdependent. I focus in particular on lynching: Lynching is a joint function of strong partisanship toward the alleged victim and weak partisanship toward the alleged offender. Unequal strong partisanship appears in both classic lynchings and communal lynchings across societies and history. Where partisanship is weak or strong on both sides, lynching is unlikely to occur. Evidence includes patterns of lynching in various tribal societies, the American South, imperial China, and medieval Europe. (shrink)

Le dernier Foucault a donné à Platon et au platonisme un rôle très important dans le surgissement de la culture ancienne de soi et dans ce qu’il a appelé « l’esthétique de l’existence ». Mais sa position en rapport à Platon et au platonisme est très complexe et ambigüe. Foucault se déplace d’un anti-platonisme d’allure nietzschéenne dont le thème général serait « la vérité du pouvoir », à une position que l’on pourrait nommer « platonicienne », où le thème « (...) le pouvoir de la vérité » apparaît. Il s’agirait d’un déplacement d’une position anti-philosophique à une autre position philosophique où Foucault chercherait un concept de philosophie à la valeur transhistorique en référence à Platon et dans son extrême radicalisation dans le cynisme. Cette clé platonicienne du dernier Foucault pourrait jeter un peu plus de lumière sur le projet général d’une « ontologie de l’actualité ». (shrink)

Arguments are given in favor of a stochastic theory of quantum mechanics, clearly distinguishable from Brownian motion theory. A brief exposition of the phenomenological theory of stochastic quantum mechanics is presented, followed by a list of its main results and perspectives. A possible answer to the question about the origin of stochasticity is given in stochastic electrodynamics by assigning a real character to the vacuum radiation field. This theory is shown to reproduce important quantum mechanical results, some of which are (...) presented explicitly to illustrate its potentialities. Finally the main problems and some perspectives of research within stochastic electrodynamics are discussed. (shrink)

The origin of the wave properties of matter is discussed from the point of view of stochastic electrodynamics. A nonrelativistic model of a charged particle with an effective structure embedded in the random zeropoint radiation field reveals that the field induces a high-frequency vibration on the particle; internal consistency of the theory fixes the frequency of this jittering at mc2/ħ. The particle is therefore assumed to interact intensely with stationary zeropoint waves of this frequency as seen from its proper frame (...) of reference; such waves, identified here as de Broglie's phase waves, give rise to a modulated wave in the laboratory frame, with de Broglie's wavelength and phase velocity equal to the particle velocity. The time-independent equation that describes this modulated wave is shown to be the stationary Schrödinger equation (or the Klein-Gordon equation in the relativistic version). In a heuristic analysis appled to simple periodic cases, the quantization rules are recovered from the assumption that for a particle in a stationary state there must correspond a stationary modulation.Along an independent and complementary line of reasoning, an equation for the probability amplitude in configuration space for a particle under a general potential V(x) is constructed, and it is shown that under conditions derived from stochastic electrodynamics it reduces to Schrödinger's equation. This equation reflects therefore the dual nature of the quantum particles, by describing simultaneously the corresponding modulated waveand the ensemble of particles. (shrink)

European Journal of Political Theory, Volume 21, Issue 3, Page 491-513, July 2022. This article is an exercise in theory-building about the stories that justify, feed upon, and reproduce systems of oppression. I argue that emotional narratives contribute to the constitution and reproduction of systems of oppression, and that different emotional narratives constitute different forms of oppression. I examine two of these emotional narratives: a narrative articulated around pity and a narrative that draws on fear. I propose that the former (...) prevails when those in power do not perceive the members of the oppressed group as posing a threat to their power structure, in turn inducing low-intensity charitable state action. Conversely, narratives that deploy fear prevail when the group in power believes that the oppressed group presents a threat to their power structure, in turn eliciting high-intensity repressive state action. While narratives of pity recur to the infantilization of the members of the disadvantaged group, narratives of fear animalize them. (shrink)

Even though Patrick Suppes made important contributions to utility theory, his final views on economic choice are quite critical of the expected-utility theories of rational choice. The aim of the present paper is to expose in a unified way his final views on economic choice and freedom. These views are part of his conception of causality and rationality.

The aim of the present paper is to attack some of the conceptual problems that arise when the framework of mathematical learning theory is applied to the description of the behavior of the firm, in setting prices and production quotas, in a competitive market. The goal is to depict the process by which the firm fixes prices and production quotas as a stochastic learning process. A solution to such problems is proposed which is based on statistical-decision concepts. The conceptualization of (...) the behavior of the firm by means of concepts pertaining to mathematical learning theory gives rise to certain mathematical problems, which are formulated here in rather precise terms.

Herman Dooyeweerd ( 1985 ) argued that among the modalities making up the fabric of reality a specifically economic one is to be found. The aim of the present paper is to discuss the texture of such a modality and how it both differentiates and intertwines with others. For an updated brief, albeit cogent and analytically lucid presentation of the Law Framework ontology, see Clouser ( 2009 ). Dooyeweerd’s view entails that the proper object of economics is irreducible to that (...) of other disciplines, but a non-reductionist view of the object of economics presupposes that the nuclear meaning of that discipline has been clearly delimited: this is required in order to determine its nature and separate identity as a scientific discipline. By ‘the nuclear meaning of a discipline’ I understand a pre-theoretical delimitation of its field of research, such as that of the field of physics, characterized by the laws governing force and energy. Within one and the same field there may be many theories, theories competing to explain the same phenomena, or dealing with phenomena so different that it is nearly impossible to trace conceptual connections among them. This last situation calls for a unified-field theory. In the second section of this paper I will attempt to defend a rather commonly accepted definition of the field of economics that sees this discipline as a science of choice. In the third I will show how the analytical conception it involves can be naturally complemented with a classificatory one. According to a classificatory conception, the aggregated social-level phenomena, patterns and regularities economic theories usually deal with, are economic in that sense, even though they are not prima facie cases of individual behavior, or are unintended consequences of aggregated individual choices. In the fourth I will discuss the meaning of the most general, supra-arbitrary economic laws—the modal laws of economics. In the final section I will offer a non-reductionist view of economics that nevertheless takes into account its intertwining with other spheres. (shrink)

Herman Dooyeweerd’s classical characterization of the meaning-kernel of the economic modality runs as follows:the sparing or frugal mode of administering scarce goods, implying an alternative choice of their destination with regard to thesatisfaction of different human needs.My first aim in this paper is to show that Dooyeweerd’s characterization of the meaning-kernel of the economic modality naturallyleads to neoclassical economic theory. In order to do this, I will provide an argument that, departing from Dooyeweerd’s definitionof the meaning-kernel of the economic modality, (...) concludes in a logical reconstruction of neoclassical economictheory . The fundamental law of this theory will turn out to be thus, naturally, a formulation of thefundamental modal law of economics. The second aim of the paper is epistemological since it discusses the methodological problem of the empirical claim of the theory. It is my hope that this discussion will clarify the limits of NET and provide a reply to the objections raised against it by Reformed scholars like Goudzwaard. (shrink)

The connection between stochastic electrodynamics (SED) and the quantum theory of matter is further explored. The main result is that the Fokker-Planck-like equation of SED can be recast into the form of a Schrödinger equation with radiative corrections, when the system is close to a state of equilibrium. The phase-space distribution can be written as Wigner's pseudo-distribution plus corrections due to the nonlinearity of the external force and to radiative effects. The radiative corrections predicted by the theory, namely the Lamb (...) shift and the decay of excited atomic states, coincide with those predicted by QED. Moreover, the theory offers a clear physical interpretation of these phenomena as due to the coupling of the electric dipole of the system with the zero-point radiation field and to radiation reaction, respectively.

The self- vs. external-regulation behavior theory, SR-ER Theory model has postulated the Self-Regulation /Non or De-Regulation/Dys-regulation continuum in the person and in their context. The model also generates a behavioral heuristic that allows us to predict and explain the variability of other dependent behavioral variables in a range of scenarios. Consequently, the objective of this study was to validate the different scales prepared on the basis of the theory presented. A total of 469 students voluntarily completed at different times the (...) five questionnaires presented, to give a total of 1,385 completed questionnaires. Using an ex post facto design, descriptive, correlational, confirmatory factorial analysis, reliability, and concurrent validity analyses were carried out. The scales were analyzed individually and as a whole. The results showed the acceptable structure of scale and consistent levels of reliability. The five levels generated by the SR-NR-DR combinatory heuristic that arises from the theoretical model determined significant differences in the levels of the variables analyzed for each psychological context. We discuss the theoretical implications and the implications for the assessment and improvement of the behaviors analyzed in function of the personal and contextual regulation levels evaluated.

Economists have long grappled with the problem of how economic theories relate to empirical evidence: how can abstract mathematized theories be used to produce empirical claims? How are such theories applied to economic phenomena? What does it mean to "test" economic theories? This book introduces, explains, and develops a structural philosophy of economics which addresses these questions and provides a unifying philosophical/logical basis for a general methodology of economics. The book begins by introducing a rigorous view of the logical foundations (...) and structure of scientific theories based upon the work of Alfred Tarski, Patrick Suppes, Karl Marx, and others. Using and combining their methods, the book then goes on to reconstruct important economic theories - including utility theory, game theory, Marxian economics, Sraffian economic theory, and econometrics - proving all the main theorems and discussing the key claims and the empirical applicability of each theory. Through these discussions, this book presents, in a systematic fashion, a general philosophy of economics grounded in the structural view. Offering rigorous formulations of important economic theories, A Structuralist Theory of Economics will be invaluable to all readers interested in the logic, philosophy, and methodology of economics. It will also appeal particularly to those interested in economic theory. (shrink)

The aim of the dissertation is to show that the logical foundations of the Marxian Theory of Value are reasonably sound. The first chapter presents a concise history of MTV and formulates in a detailed way the problem of foundations in MTV. This is the problem of proving the existence of labor-values in a general economy in which joint products, alternative techniques, and heterogeneous labor are allowed. ;In the second chapter the problem is tackled through the demonstration that there is (...) a measurement of abstract labor in such general systems, where abstract labor is understood as a binary relation over the set of labor expenditures induced by a system of prices, in a commodity economy, that satisfies certain properties. It is also shown that whenever the rate of profit is uniform the price system satisfies such properties. ;Using the results of the second chapter, in the last chapter an axiomatization of MTV is provided and two of the most typical models of MTV are reconstructed in terms of abstract labor in a very detailed way. The first of these is the classical Leontief model and the second one is a more general model due to John K. Roemer. The conclusion of the dissertation is that the foundations of MTV are as sound as those of Neo-classical Economics. (shrink)

Colonization has traditionally been studied as a monological and definitive period. This article seeks to problematize its analysis by means of the so-called ‘philosophy of desire’ and ‘rhizomatic thinking’, enriching them, in methodological terms, by the Actor-Network-Theory. In this vein, an alternative explanation of the colonial regime is offered by emphasizing how it assembled several worlds—Indigenous and Europeans—guided by a desiring-production that put originary accumulation before anything else; a standpoint that also enables a discussion about the network of colonial education (...) deployed in the Audiencia de Quito, which can be evidenced by a revision of some actions of the Augustinian order during the sixteenth century. In conclusion, education was deeply related to colonial assemblage that was continuously deterritorializing the ‘New World’ and the indigenous cultures that inhabited it. (shrink)

We revisit the nonrelativistic problem of a bound, charged particle subject to the random zero-point radiation field, with the purpose of revealing the mechanism that takes it from the initially classical description to the final quantum-mechanical one. The combined effect of the zpf and the radiation reaction force results, after a characteristic time lapse, in the loss of the initial conditions and the concomitant irreversible transition of the dynamics to a stationary regime controlled by the field. In this regime, the (...) canonical variables x, p become expressed in terms of the dipolar response functions to a set of field modes. A proper ordering of the response coefficients leads to the matrix representation of quantum mechanics, as was proposed in the early days of the theory, and to the basic commutator x^,p^=iħ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\left[ {\hat{x}},{\hat{p}}\right] =i\hbar $$\end{document}.

We report a scanning tunnelling microscopy investigation of the emission of dislocations around nanoindentations in the form of dislocation arrangements previously called hillocks , consisting of two pairs of Shockley partial dislocations, each encompassing a stacking fault. The spatial arrangement and size distribution of hillocks around the nanoindentation traces are studied. We show that standard dislocation theory for an isotropic continuum can be used to describe the stability of the hillocks, their size and spatial distribution and the broadening of the (...) corresponding extended dislocations near the surface. A model is proposed in which hillocks originate from the split into dislocations partials of primary perfect dislocation loops punched into the crystal by the scanning tunnelling microscope tip. This model implies the operation of a novel dislocation mechanism involving long-range transport of matter across the surface. (shrink)

Quand, en 1938, au cri de "Penser nous devons", Virginia Woolf exhorta les femmes à résister à leur assimilation "dans la procession des fils des hommes cultivés", elle ne pouvait pas imaginer qu'à peine trente ans plus tard les interventions féministes sur les savoirs scientifiques allaient non seulement prolonger la lutte pour l'égalité d'accès au savoir, mais inaugurer une critique approfondie des contenus des savoirs. Du dedans des disciplines académiques, cette lutte illumina en profondeur ce que Woolf avait déjà compris (...) : la noble idée du savoir désintéressé sert de justification pour les pires exclusions et injustices. Cet ouvrage propose un parcours original des chemins par lesquels la pensée féministe contesta le caractère "neutre" du savoir, depuis les politiques des mouvements jusqu'aux épistémologies alternatives du standpoint feminism anglo-américain.

Aristotle’s influence on D’Arcy Thompson was praised by Thompson himself and has been recognized by others in various respects, including the aesthetic and normative dimensions of biology, and the multicausal explanation of living forms. This article focuses on the relatedness of organic forms, one of the core problems addressed by both Aristotle’s History of Animals (HA), and the renowned chapter of Thompson’s On Growth and Form (G&F), “On the Theory of Transformations, or the Comparison of Related Forms.” We contend that, (...) far from being an incidental inspiration stemming from Thompson’s classicist background, his translation of HA played a pivotal role in developing his theory of transformations. Furthermore, we argue that Thompson’s interpretation of the Aristotelian method of comparison challenges the prevailing view of Aristotle as the founder of “typological essentialism,” and is a key episode in the revision of this narrative. Thompson understood that the method Aristotle used in HA to compare animal forms is better comprehended as a “method of transformations,” leading to a morphological arrangement of animal diversity, as opposed to a taxonomical classification. Finally, we examine how this approach to the relatedness of forms lay the foundation for a causal understanding of parts and their interconnections. Although Aristotle and Thompson emphasized distinct types of causes, we contend that they both differ in a fundamental sense from the one introduced by Darwin’s theory of natural selection, which was formulated as a solution to the species problem rather than the form problem. We conclude that Thompson’s interpretation of Aristotle’s approach to form comparison has not only impacted contemporary scholarship on Aristotle’s biology, but revitalized a perspective that has regained significance due to the resurgence of the problem of form in evo-devo.
