Resumo: Muitos trabalhos em história da filosofia, eminentemente em história da filosofia medieval, são marcados por uma oposição metodológica entre três abordagens: a ênfase na estrutura interna de um pensamento; a ênfase na investigação de um tema ou conceito; a ênfase na inserção de um pensamento em seu contexto histórico-filosófico. No entanto, é possível defender a aproximação dessas três abordagens, e mesmo a combinação delas, em vista de um ganho de inteligibilidade dos pensamentos estudados. É o que pretende o presente (...) artigo, procurando apontar para a artificialidade da oposição entre as três abordagens e defendendo um modelo comunicacional que a supere.: Many works in history of philosophy, especially in the history of medieval philosophy, are marked by a methodological opposition between three approaches: an emphasis on the internal structure of a thought, an emphasis on investigating a theme or concept, and an emphasis on the place of a thought in its historical-philosophical context. However, it is possible to defend the approximation of these three approaches, and even their combination, aiming at greater intelligibility of the thoughts under investigation. This article aims to point out the artificiality of the opposition between the three approaches and to defend a communicational model that overcomes it. (shrink)

One of the many research projects of Jaakko Hintikka was entitled “Logical tools for human thinking and their history”. This is in fact an apt summary of the lifetime work of this master logician who developed several new methods and systems in mathematical and philosophical logic, among them distributive normal forms, model sets, possible-worlds semantics, epistemic logic, doxastic logic, inductive logic, semantic information, game-theoretical semantics, interrogative approach to inquiry, and independence-friendly logic. He applied them to study problems in philosophy of (...) language, formal epistemology, and philosophy of science. He combined systematic work with novel interpretations of important historical figures like Aristotle, Leibniz, Kant, Peirce, and Wittgenstein. Hintikka was one of the most cited analytic philosophers, and he influenced logic and philosophy also as a successful teacher and the long-time editor of the journal Synthese. (shrink)

In his classic study,The Great Chain of Being, Arthur Lovejoy delineated a complex set of concepts and assumptions which referred to the perfection of God and the fullness of creation. In attempting to distil the basic or ‘unit idea’ which constituted this pattern of thought, he focused on the assumption that ‘the universe is aplenum formarumin which the range of conceivable diversity ofkindsof living things is exhaustively exemplified’. He called this the ‘principle of plenitude’. Lovejoy argued that this idea implied (...) two others—continuity and gradation—and that together these reflected a pre-occupation with the ‘necessity of imperfection in all its possible degrees’, a concern which had pervaded Western thought since Plato and gave rise to the powerful ontology known as the ‘great chain of being’.

The issue which I wish to address in this paper is the widespread tendency in Anglophone philosophy to insist on a separation between the history of philosophy and the history of ideas or intellectual history. This separation reflects an anxiety on the part of philosophers lest the special character of philosophy will be dissolved into something else in the hands of historians. And it is borne of a fundamental tension between those who think of philosophy's past as a source of (...) ideas and arguments of interest to the present, and those who hold that the philosophy of the past should be studied on its own terms, in relation to its immediate context, without reference to the present. The challenge, then, is to re-historicise the history of philosophy, and to keep the philosophers onside. (shrink)

The ontological argument fails because of an operator order switch between (1) “necessarily there is an perfect being” and (2) “there is a being which necessarily is perfect”. Here (1) is trivially true logically but (2) problematic. Since Kant's criticisms were directed at the notion of existence, not at the step from (1) to (2), they are misplaced. They are also wrong, because existence can be a predicate. Moreover, Kant did not anticipate Frege's claim that “is” is ambiguous between existence, (...) predication, identity, and class‐inclusion. To restore the ontological argument, an extra premise is needed to the effect that it is known who the existentially perfect being is. The question is raised whether Kant could have meant the failure of this extra premise by his thesis that existence is not a real predicate. (shrink)

Carnap's philosophy is examined from new viewpoints, including three important distinctions: (i) language as calculus vs language as universal medium; (ii) different senses of completeness: (iii) standard vs nonstandard interpretations of (higher-order) logic. (i) Carnap favored in 1930-34 the "formal mode of speech," a corollary to the universality assumption. He later gave it up partially but retained some of its ingredients, e.g., the one-domain assumption. (ii) Carnap's project of creating a universal self-referential language is encouraged by (ii) and by the (...) author's recent work. (iii) Carnap was aware of (iii) and occasionally used the standard interpretation, but was not entirely clear of the nature of the contrast. (shrink)

We propose a new method for the history of ideas that has none of the shortcomings so often ascribed to this approach. We call this method the model approach to the history of ideas. We argue that any adequately developed and implementable method to trace continuities in the history of human thought, or concept drift, will require that historians use explicit interpretive conceptual frameworks. We call these frameworks models. We argue that models enhance the comprehensibility of historical texts, and provide (...) historians of ideas with a method that, unlike existing approaches, is susceptible neither to common holistic criticisms nor to Skinner's objections that the history of ideas yields arbitrary and biased reconstructions. To illustrate our proposal, we discuss the so-called Classical Model of Science and draw upon work in computer science and cognitive psychology. (shrink)
