Many contributors of the debate about knowledge by testimony concentrate on the problem of justification. In my paper I will stress a different point – the concept of testimony itself. As a starting point I will use the definitional proposal of Jennifer Lackey. She holds that the concept of testimony should be regarded as entailing two aspects – one corresponding to the speaker, the other one to the hearer. I will adopt the assumption that we need to deal with both (...) aspects. Nevertheless, I will show that her concept – which suggests regarding testimony as an act of communication conveying information – is too broad and, therefore, I will end up with a different twofold definition.

The basic tendencies in the conceptual history of the 'subject' within Russian intellectual history are presented. This backgrounds a closer analysis of S. Trubetskoj's concept of 'conciliar consciousness', including the problems and aporiae connected with it. It will be shown that and how this conception depends on assumptions from prekantian metaphysics and therefore ignores the Kantian account of subjectivity.

Arthur Pap’s work played an important role in the development of the analytic tradition. This role goes beyond the merely historical fact that Pap’s views of dispositional and modal concepts were influential. As a sympathetic critic of logical empiricism, Pap, like Quine, saw a deep tension in logical empiricism at its very best in the work of Carnap. But Pap’s critique of Carnap is quite different from Quine’s, and represents the discovery of limits beyond which empiricism cannot go, where there (...) lies nothing other than intuitive knowledge of logic itself. Pap’s arguments for this intuitive knowledge anticipate Etchemendy’s recent critique of the model-theoretic account of logical consequence. Pap’s work also anticipates prominent developments in the contemporary neo-Fregean philosophy of mathematics championed by Wright and Hale. Finally, Pap’s major philosophical preoccupation, the concepts of necessity and possibility, provides distinctive solutions and perspectives on issues of contemporary concern in the metaphysics of modality. In particular, Pap’s account of modality allows us to see the significance of Kripke’s well-known arguments on necessity and apriority in a new light. (shrink)

This paper investigates the relationship between some corpuscularian and Aristotelian strands that run through the thought of the sixteenth-century philosopher and physician Julius Caesar Scaliger. Scaliger often uses the concepts of corpuscles, pores, and vacuum. At the same time, he also describes mixture as involving the fusion of particles into a continuous body. The paper explores how Scaliger’s combination of corpuscularian and non-corpuscularian views is shaped, in substantial aspects, by his response to the views on corpuscles and the vacuum in (...) the work of his contemporary, Girolamo Fracastoro. Fracastoro frequently appears in Scaliger’s work as an opponent against whom numerous objections are directed. However, if one follows up Scaliger’s references, it soon becomes clear that Scaliger also shares some of Fracastoro’s views. Like Scaliger, Fracastoro suggests corpuscularian explanations of phenomena such as water rising in lime while at the same time ascribing some non-corpuscularian properties to his natural minima. Like Scaliger, Fracastoro maintains that there is no vacuum devoid of bodies since places cannot exist independently of bodies (although their opinions diverge regarding how exactly the relevant dependency relation might be explicated). Finally, like Scaliger, Fracastoro connects a continuum view of mixture with a theory of natural minima. (shrink)

Idealist Heresies in Philosophy of Science: Cassirer, Carnap, and Kuhn. As common wisdom has it, philosophy of science in the analytic tradition and idealist philosophy are incompatible. Usually, not much effort is spent for explaining what is to be understood by idealism. Rather, it is taken for granted that idealism is an obsolete and unscientific philosophical account. In this paper it is argued that this thesis needs some qualification. Taking Carnap and Kuhn as paradigmatic examples of positivist and postpositivist philosophies (...) of science it is shown that these accounts share important features with Cassirer's idealist philosophy of science developed in the first half of this century. As it turns out, often Cassirer is more modern than those classical philosophers of (post)posivitist philosophy of science. For instance, Quine's criticism against Carnap's empiricist philosophy of science launched in Two Dogmas of Empiricism is anticipated by Cassirer for several decades. (shrink)

The article considers Cassirer’s philosophy of mathematics in opposition to empiricist theories, Frege’s logicism, and its realism, Hilbert’s formalism and its nominalism, and Brouwer’s intuitionism grounding mathematics in the intuition of time. For Cassirer mathematical objects are purely relational structures and not abstractions of certain characteristics, as is the case with empiricists and Frege. In opposition to logicists, Cassirer argues for the synthetic nature of mathematics. Contrary to Brouwer, he does not ground this in intuition but ascribes to mathematics a (...) purely logical nature and relates it to the purely rational faculty of the spirit. He thus turns away from Hilbert, who takes sensuous objects to be the object of mathematics; he also cannot agree with his formalism, which reduces all progress in mathematics to a mere combination of signs, thus stripping it of all meaning. The article considers these differences in view of the opposition between the cardinal and ordinal theories of number and the introduction of ideal elements. (shrink)

In 1870, Hermann von Helmholtz criticized the Kantian conception of geometrical axioms as a priori synthetic judgments grounded in spatial intuition. However, during his dispute with Albrecht Krause (Kant und Helmholtz über den Ursprung und die Bedeutung der Raumanschauung und der geometrischen Axiome. Lahr, Schauenburg, 1878), Helmholtz maintained that space can be transcendental without the axioms being so. In this paper, I will analyze Helmholtz’s claim in connection with his theory of measurement. Helmholtz uses a Kantian argument that can be (...) summarized as follows: mathematical structures that can be defined independently of the objects we experience are necessary for judgments about magnitudes to be generally valid. I suggest that space is conceived by Helmholtz as one such structure. I will analyze his argument in its most detailed version, which is found in Helmholtz (Zählen und Messen, erkenntnistheoretisch betrachtet 1887. In: Schriften zur Erkenntnistheorie. Springer, Berlin, 1921, 70–97). In support of my view, I will consider alternative formulations of the same argument by Ernst Cassirer and Otto Hölder. (shrink)

Ludwik Fleck is a pioneer of the contemporary social constructionist trend in scientific theory, where his central concept of thinking style has become standard fare. Yet the concept is too often misunderstood and simplified with serious consequences not only for Fleck studies. My essay situates Fleck’s concept of thinking style in the historical context of the 1920s and ‘30s, when the notion of style was first applied to the natural sciences, in order to illustrate the uniqueness of Fleck’s concept among (...) the uses of style by his contemporaries and, finally, to examine the epistemological, methodological, and political consequences of this distinction.

The paper focuses on the epistemology developed by Richard Burthogge, the lesser-known seventeenth-century English philosopher, and author, among other works, of Organum Vetus & Novum (1678) and An Essay upon Reason and the Nature of Spirits (1694). Although his ideas had a minimal impact on the philosophy of his time, and have hitherto not been the subject of a detailed study, Burthogge’s writings contain a highly original concept of idealistic constructivism, anticipating (relatively speaking) Kant’s idealism. At the same time, some (...) interesting implications for the issue of self-interpretation and self-identity can be derived from his account of the mind. At the core of Burthogge’s epistemological position is a remarkable idea of structural and functional similarity between the three human cognitive faculties, that is between reasoning, sensation and imagination. Accordingly, every cognition, intellectual as well as sensuous, contains in its structure an object-directed operation of apprehending and thus can be viewed as an intentional act in a broad sense of the term. An immediate consequence of this claim for both mind and object is that they cannot be reduced to a pure stream of sense data, but on the contrary are to be considered ontologically independent from the content of a cognitive act. Furthermore, an object of cognition is never presented to the mind directly, as it is in itself, but always under the modus concipiendi, a particular form or manner of conceiving, specific to human cognitive powers due to their internal structure. As a result, Burthogge clearly anticipates Kant in claiming that it is impossible to know reality in itself, and in situating human consciousness as if in between two unknowable spheres: the external and internal one. Since these restrictions are imposed not only on external, but also on internal cognition, that is on self-knowledge, they lead to considerable difficulties regarding the mind’s identity. Basically, two principal strategies to address this issue are available in the post-Cartesian framework of seeing the mind as an ontologically independent entity, and both of them appear to be ineffective when employed in Burthogge’s epistemology. First, the mind identity can be grounded in some extra-mental factors, preferably in matter. However, with no access to the external world in itself, and with the scope of knowledge restricted to mental phenomena, the mind’s identity cannot be defined in terms of relationship with the reality of which it knows nothing except that it exits. The second option is to explain personal identity by referring it to the intrinsic properties of the mind. Nevertheless, this strategy also faces insuperable obstacles, and for the same reasons as the former does. Since self-knowledge is no exception to the structural-functional principles imposed on cognition, the mind can also be known only under the subjective conditions of conceiving. It is, therefore, just as unknowable in itself as the external things are. The main purpose of the paper is to explore this aspect of Burthogge’s philosophy. (shrink)

"Theory of modus concipiendi in Richard Burthogge’s Epistemology" The paper focuses on the epistemology of Richard Burthogge, the lesser known seventeenth-century English philosopher and author, among other works, of the Organum Vetus & Novum (1678) and An Essay upon Reason and the Nature of Spirits (1694). Although his ideas had a minimal impact on the philosophy of his time, and have hitherto not been the subject of a detailed study, Burthogge’s writings contain a highly original concept of idealistic constructivism. The (...) most important claim of this approach is that the external objects are never presented to the mind directly, as they are in themselves, but always under the modus concipiendi, a particular form of conceiving or conceptualising, performed by the human cognitive powers (both intellectual and sensuous) in the manner and with the means determined by their structural and functional properties. Thus, Burthogge clearly anticipates Kant in claiming that the external world is unknowable in itself, being accessible to the human mind only through the phenomena that the mind itself co-produces. The paper provides an outline of the theory of modus concipiendi, including its historical context and idealistic consequences, preceded by the brief presentation of Burthogge’s epistemology.

The aim of this paper is to take Galileo's mathematization of nature as a springboard for contrasting the time-honoured empiricist conception of phenomena, exemplified by Pierre Duhem's analysis in To Save the Phenomena , with Immanuel Kant's. Hence the purpose of this paper is twofold. I) On the philosophical side, I want to draw attention to Kant's more robust conception of phenomena compared to the one we have inherited from Duhem and contemporary empiricism. II) On the historical side, I want (...) to show what particular aspects of Galileo's mathematization of nature find a counterpart in Kant's conception of phenomena.------------------------------------------------------------------------------------------ ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- --------------------------------------------------.

From the perspective of Cartesian doubt, this article explores the concept of the limitations of reasoning through the use of the Kantian words 'boundary' and 'barrier' in his Critique of Pure Reason. Hegel's critical dialogue with Kant is presented focusing on the limitation that the latter imposed on reason for the acquisition of the true knowledge of philosophical/metaphysical objects. For this purpose, the Hegelian position is presented from its discussion on the second chapter of the first section of the The (...) Doctrine of Being and references are made to conceptual elements of the Phenomenology of Spirit. (shrink)

In the Appendix to the Transcendental Dialectic, Kant formulates teleological principles, or rather ideas, and explicates them referring to concrete examples of natural science such as chemistry, astronomy, biology, empirical psychology, and physical geography. Despite the increasing interest in the systematic relevance of the Appendix to the Transcendental Dialectic and its importance for Kant’s conception of natural science, the numerous historical sources for the regulative use of reason have not yet been investigated. One that is very central is Maupertuis’ principle (...) of least action. In 1781, Kant transformed teleology into heuristics and methodology, but in doing so, he partially develops a teleology which was disqualified by Maupertuis because its starting point lies in the construction of animals or plants, the structure of the earth, and the immensity of the celestial bodies. Based on Maupertuis’ principle of action, it can be shown that the Appendix forms a systematic interface between Universal Natural History and Theory of the Heavens and Critique of Judgement which allows the reconstruction of Kant’s regulative use of reason and its specific status in the context of natural science and his critical appraisal of Maupertuis.

To explore the relation between mathematical models and reality, four different domains of reality are distinguished: observer-independent reality, personal reality, social reality and mathematical/formal reality. The concepts of personal and social reality are strongly inspired by constructivist ideas. Mathematical reality is social as well, but constructed as an autonomous system in order to make absolute agreement possible. The essential problem of mathematical modelling is that within mathematics there is agreement about ‘truth’, but the assignment of mathematics to informal reality is (...) not itself formally analysable, and it is dependent on social and personal construction processes. On these levels, absolute agreement cannot be expected. Starting from this point of view, repercussion of mathematical on social and personal reality, the historical development of mathematical modelling, and the role, use and interpretation of mathematical models in scientific practice are discussed.

Článek se zabývá pojmem panteismus v období renesance. Ačkoli termín panteismus se objevil až na konci 17. století a později v kontextu tzv. “Pantheismusstreit”, za předchůdce moderního panteistického myšlení byl označen renesanční filosof Giordano Bruno. Následně i Mikuláš Kusánský, a to jakožto pokračovatel myšlení Mistra Eckharta, začal být považován za panteistu. Jak Kusánský, tak Bruno v určitém smyslu obhajovali imanenci božského ve světě, avšak zároveň oba zdůrazňovali rozdíl mezi Bohem a přírodou a připisovali Bohu transcendenci nebo přinejmenším transcendentální aspekty. Toto (...) není v souladu s definicí panteismu v tzv. silném slova smyslu, kdy se tvrdí striktní identita Boha a světa. Zdá se, že pojem renesanční panteismus je konstruktem, který byl vytvořen skrze násilnou aplikaci terminologie osvícenské filosofie na renesanční období. (shrink)

The meaning and validity of Kant’s Kant’s doctrine of schematism remains contested until today. In neo-Kantianism and post-War transcendental philosophy, Kant’s schematism of the pure concepts of understanding is transformed drastically. Kant’s thesis of heterogeneity is overcome by taking it back into the internal relationships of the structure of cognition. The spontaneity of thought, performing schematizations, is retained, but Kant’s project of conceiving of the foundations of knowledge in the fashion of a theory of apperception of the I as well (...) as the externality of the given and the determination of the given that goes along with it is sublated by an objective order of validity-noematic constitution and regulation. Kant’s doctrine of schematism, then, shows to be methodology. (shrink)

The paper is devoted to an overview of Cassirer’s work both as historian of philosophy and historian of science. Indeed, the “intelletcual cooperation” between history of philosophy and history of science represents an essential feature of Cassirer’s style of philosophizing: while the roots of a wide exploration stretching from Renaissance thought to modern physics go back to the Neo-Kantianism of the Marburg School, the results of a similar cross-fertilization of research fields have deeply contributed to shaping new standards of inquiry. (...) Cassirer’s relationship with the Warburg milieu in Hamburg and late in his life with the American intellectual scenario are surely worthy of closer investigation. Distinguished scholars such as Meyerson, Brunschvicg, Burtt, Koyré, Metzger, Lovejoy, Kristeller, have disussed, appreciated, critizised Cassirer’s still today fascinating studies devoted to Pico della Mirandola, Galileo, Newton, Leibniz, to mention but a few. To explore some of these aspects focusing both on affinities and differences within a cosmpolitian intellectual community can provide a better understanding of philosophy and history of science in the first half of 20th century. Cassirer’s legacy requires, therefore, a new assessment. (shrink)

Whenever one reads internal histories of psychology what is covered is the establishment of a lab by Wundt in 1879 as the initiating act and then the breakaway movements of the 20th Century are discussed: Behaviorism, Gestalt Theory, Psychoanalysis, and most recently the Cognitive revival. However, Aron Gurwitsch described a perspective noted by Cassirer and first developed by Malebranche, which dates the founding of psychology at the same time as that of physics in the 17th Century. This external perspective shows (...) the dependency of psychology upon the concepts, methods and procedures of physics and the natural sciences in general up until the present time. Gurwitsch argues that this approach has blocked the growth of psychology and has assured its status as a minor science. He argued that the everyday Lifeworld achievements of subjectivity are the true subject matter of psychology and that a phenomenological approach to subjectivity could give psychology the authenticity it has been forever seeking but never finding as a naturalistic science. Some clarifying thoughts concerning this phenomenologically grounded psychology are offered, especially the role of desire. The assumption of an external perspective toward the history of psychology fostered the insights about psychology’s scientific role. (shrink)

The founders of the Marburger Schule of Neo-Kantianism, Hermann Cohen and Paul Natorp, laid an emphasis upon a Platonic understanding of mathematics and logic as the paradigmatic epistemological basis of philosophy. Their successors, namely Ernst Cassirer and Nicolai Hartmann, made obvious, however, that new biological thinking can have a strong influence on ontology as well as on the theory of knowledge. They could show that biology was no longer to be treated as a metaphysical system in that pejorative meaning of (...) metaphysics which Kant had so severely been opposing. Against the anti-realistic approach of the older neo-Kantians who wanted to eliminate Kant's thing-in-itself (Ding an sich), both Cassirer and Hartmann returned to a form of realism by way of Hegel's philosophical results and reflections on his method. This makes clear that their realism is still to be taken as a more of less monistic idealism. However, considering that modern biology as an antimetaphysical force became influential in their system for the first time and that it did so in two different but - on second thoughts - complementary ways, it becomes clear that it was necessary to change the paradigms of any neo-Kantian philosophy. Cassirer proved this by his development as a philosopher with a strong historical impetus while Hartmann as a more systematical philosopher only pointed in that direction. (shrink)

On 11thOctober 2007, at the first international conference on Integrated History and Philosophy of Science (&HPS1) hosted by the Center for Philosophy of Science in Pittsburgh, Ernan McMullin (University of Notre Dame) portrayed a rather gloomy scenario concerning the current relationship between history and philosophy of science (HPS), on the one hand, and mainstream philosophy, on the other hand, as testified by a significant drop in the presence of HPS papers at various meetings of the American Philosophical Association (APA).
