Kelly suggested that it was useful to consider anyone as functioning as a scientist, in the business of applying theories, making hypotheses and predictions and testing them out in the practice of everyday life. One of Charles Peirce’s major contributions was to develop the disciplines of logic and the philosophy of science. We can deepen and enrich our understanding of Kelly’s vision by looking at what Peirce has to say about the process of science. For Peirce, the essence of science (...) was the application of the laws of inference. He developed a much broader concept of logic, elaborating the processes of deduction and induction and adding to these the logic of hypothetical inference, or ‘abduction’, even as Kelly broadened it further in his “departure from classical logic”. Examining the implications of these three forms of inference allows us to elaborate the dynamics involved in the process of construing, ordinacy and the cycles of experience, creativity and decision making. This is the second of a three part series examining the relationship between the work of Peirce and Kelly. The third will include a look at phenomenology, bipolarity, the self, dialogical process and sociological considerations. (shrink)

Modality and Anti-Metaphysics critically examines the most prominent approaches to modality among analytic philosophers in the twentieth century, including essentialism. Defending both the project of metaphysics and the essentialist position that metaphysical modality is conceptually and ontologically primitive, Stephen McLeod argues that the logical positivists did not succeed in banishing metaphysical modality from their own theoretical apparatus and he offers an original defence of metaphysics against their advocacy of its elimination. -/- Seeking to assuage the sceptical worries which underlie modal (...) anti-realism, McLeod provides an original contribution to essentialist epistemology, engaging with current debates about modality and suggesting that standard essentialist approaches to some issues in the philosophies of logic and language require revision. -/- This book offers valuable insights to professional philosophers, postgraduates and advanced undergraduates interested in metaphysics, philosophy of logic or the history of twentieth-century analytic philosophy.

A system of categories is a complete list of highest kinds or genera. Traditionally, following Aristotle, these have been thought of as highest genera of entities (in the widest sense of the term), so that a system of categories undertaken in this realist spirit would ideally provide an inventory of everything there is, thus answering the most basic of metaphysical questions: “What is there?”. Skepticism about the possibilities for discerning the different categories of ‘reality itself’ has led others to approach (...) category systems not with the aim of cataloging the highest kinds in the world itself, but rather with the aim of elucidating the categories of our conceptual system. Thus Kant makes the shift to a conceptualist approach by drawing out the categories that are.. (shrink)

http://dx.doi.org/10.5007/1808-1711.2012v16n1p53 Ratifying Haeckel and contradicting Kant’s negative prophesy, in this paper I try to show that Darwin was, really, the Newton of the blade of grass . Darwin showed how the configurations according to goals of the living beings, could be explained from a naturalistic point of view, without having to postulate the existence of an intentional agent that had arranged or prearranged then. This achievement, nevertheless, was obtained by a way that Kant could not foresee and that Haeckel could (...) not understand: Darwin came there showing that there was more natural science than that Newton, Kant and Haeckel could conceive.

The paper discusses the Kantian legacy in modern views about scientific theories. The aim of this paper is to show how Einstein's philosophy of science, which was inspired by his physics, offers a specialized version of the Kantian synthesis of Empiricism and Rationalism. In modern physical theories Kant's a priori conditions become “constraints,” as shown in Einstein's use of principle theories. Einstein's use of principle theories shows how constraints are used to steer the mapping of the rational onto the empirical (...) elements of scientific theories. (shrink)

This paper asks how we find our way in the hitherto unknown. In search of an answer, the author returns to the three Critiques of Immanuel Kant, noting especially their grounding in the geometric mode of (re)presentation and the thingification processes connected therewith. It is argued that Kant's choice of metaphors in effect makes him more of a geographer than of a philosopher. To understand the taken-for-granted of thought-and-action, the time has therefore come for the writing of a fourth volume (...) entitled A Critique of Cartographical Reason. The focus must there be on the relations between personal pronouns and prepositions, on the one hand, and the powers of tautology, on the other. (shrink)

In the Critique of Pure Reason, Kant conceives of general logic as a set of universal and necessary rules for the possibility of thought, or as a set of minimal necessary conditions for ascribing rationality to an agent . Such a conception, of course, contrasts with contemporary notions of formal, mathematical or symbolic logic. Yet, in so far as Kant seeks to identify those conditions that must hold for the possibility of thought in general, such conditions must hold a fortiori (...) for any specific model of thought, including axiomatic treatments of logic and standard natural deduction models of first-order predicate logic. Kant's general logic seeks to isolate those conditions by thinking through – or better, reflecting on – those conditions that themselves make thought possible. (shrink)

The paper is a preliminary examination of the origin and role of psychological perception or “feeling” of dignity in human beings. Following Ayala's naturalistic account of morality, a sense of emotional dignity is seen as an outcome of processes of natural selection, cultural evolution, and above all a need for social inclusion. It is suggested that the existence of emotional dignity as part of a human species-related continuum provides an explanation of why we treat those in a persistent vegetative state, (...) the severely and hopelessly mentally impaired, the senile demented, cadavers and archaeological remains with dignity and respect. For older Europeans, dissonance between physical and mental abilities, unfamiliarity with social and cultural changes and relative proximity to death may influence their emotional dignity and hence vulnerability.

I argue that, by the time of his essay "Concerning the Ultimate Ground of the Differentiation of Directions in Space" (1768), Kant had come to question the status of the Principle of Sufficient Reason as a result, at least in part, of his recognition of the existence of incongruent counterparts. Though Kant's argument against absolute space based on the existence of incongruent counterparts has been much discussed in recent years, its importance as a useful benchmark by which to judge the (...) direction of Kant’s thinking during this period has gone unnoticed. This paper is a modest attempt to remedy this deficiency. (shrink)

From the late 1790s to the early 1890s, Scottish scholars contributed, as translators, commentators, or critics to the ‘reception’ of Kant's philosophy in Britain. The discussion here considers particularly the work of Richardson, Semple, Gillies, MacVicar, Ferrier, Meiklejohn, and Hastie, and attempts to assess the character, quality, and value of their contributions to Kantian scholarship. An important question throughout is whether – and if so, how far and why – the work of Scottish Kantians can be meaningfully discussed apart from (...) their English contemporaries – one relevant consideration being the distinctive rôle of philosophy in the Scottish M.A. curriculum.

En el “Prólogo” a sus Primeros principios metafísicos de la ciencia de la naturaleza, Kant sostiene que la psicología empírica, a diferencia de la física matemática y la química flogística, no es una ciencia de la naturaleza. Este artículo se propone ofrecer una interpretación de las razones por las cuales Kant atribuye este estatus a la psicología empírica. Mostraré, por un lado, que la psicología empírica no posee un carácter científico en sentido propio como la física matemática porque los fenómenos (...) internos no pueden presentarse a priori como movimientos en el espacio; y, por el otro, que esta psicología no posee un carácter científico en sentido impropio como la química flogística porque no es posible realizar experimentos ni observaciones rigurosas en el dominio del sentido interno. La psicología empírica es una mera descripción natural, sistemática y clasificatoria, de los fenómenos del sentido interno. (shrink)

A comprehensive survey of Martin-Löf's constructive type theory, considerable parts of which have only been presented by Martin-Löf in lecture form or as part of conference talks. Sommaruga surveys the prehistory of type theory and its highly complex development through eight different stages from 1970 to 1995. He also provides a systematic presentation of the latest version of the theory, as offered by Martin-Löf at Leiden University in Fall 1993. This presentation gives a fuller and updated account of the system. (...) Earlier, brief presentations took no account of the issues related to the type-theoretical approach to logic and the foundations of mathematics, while here they are accorded an entire part of the book. Readership: Comprehensive accounts of the history and philosophy of constructive type theory and a considerable amount of related material. Readers need a solid background in standard logic and a first, basic acquaintance with type theory. (shrink)
