Throughout more than two millennia philosophers adhered massively to ideal standards of scientific rationality going back ultimately to Aristotle’s Analytica posteriora . These standards got progressively shaped by and adapted to new scientific needs and tendencies. Nevertheless, a core of conditions capturing the fundamentals of what a proper science should look like remained remarkably constant all along. Call this cluster of conditions the Classical Model of Science . In this paper we will do two things. First of all, we will (...) propose a general and systematized account of the Classical Model of Science. Secondly, we will offer an analysis of the philosophical significance of this model at different historical junctures by giving an overview of the connections it has had with a number of important topics. The latter include the analytic-synthetic distinction, the axiomatic method, the hierarchical order of sciences and the status of logic as a science. Our claim is that particularly fruitful insights are gained by seeing themes such as these against the background of the Classical Model of Science. In an appendix we deal with the historiographical background of this model by considering the systematizations of Aristotle’s theory of science offered by Heinrich Scholz, and in his footsteps by Evert W. Beth. (shrink)

This paper concentrates on some aspects of the history of the analytic-synthetic distinction from Kant to Bolzano and Frege. This history evinces considerable continuity but also some important discontinuities. The analytic-synthetic distinction has to be seen in the first place in relation to a science, i.e. an ordered system of cognition. Looking especially to the place and role of logic it will be argued that Kant, Bolzano and Frege each developed the analytic-synthetic distinction within the same conception of scientific rationality, (...) that is, within the Classical Model of Science: scientific knowledge as cognitio ex principiis . But as we will see, the way the distinction between analytic and synthetic judgments or propositions functions within this model turns out to differ considerably between them. (shrink)

Where the possibility of metaphysics as a science is concerned, Kant assigns the exact sciences the function of an exemplar; for these disciplines have long been well established on "the secure path of a science." Accordingly, in the Prolegomena Kant explicitly addresses the question "How is metaphysics possible as a science?" by way of the questions "How is pure mathematics possible?" and "How is pure natural science possible?" Moreover, all these questions arise directly out of the main transcendental question: "How (...) are synthetic judgments a priori possible?" The deplorable situation of the metaphysics of the day would have been entirely attributable to misappraisal of this central transcendental question. (shrink)

Quine's well-known ‘Two Dogmas of Empiricism’ (1951) plays a key role in the debate about the analytic-synthetic distinction. Taking to task the ideas of Carnap in particular, Quine shows that logical positivism works with a concept of scientific rationality that is based dogmatically on, among other things, the opposition analytic-synthetic.

Kant's distinction between analytic and synthetic method is connected to the so-called Aristotelian model of science and has to be interpreted in a (broad) directional sense. With the distinction between analytic and synthetic judgments the critical Kant did introduced a new way of using the terms 'analytic'-'synthetic', but one that still lies in line with their directional sense. A careful comparison of the conceptions of the critical Kant with ideas of the precritical Kant as expressed in _Ãœber die Deutlichkeit, leads (...) to the interpretation defended here of Kant's distinction between analytic and synthetic judgments within his philosophy of mathematics.

This paper analyses the relationship between Hobbes's theory of language and his theory of science and method. It is shown that Hobbes, at least in his Computatio sive Logica (1655), deviates in some measure from the traditional (Aristotelian) model of language. In this model speech is considered to be a fairly unproblematic expression of thought, which itself is independent of language. Basing himself on a nominalist account of universals, Hobbes states that the demonstration or assertion of universal propositions presupposes speech (...) (more especially, the use of names as marks). This insight turns out to be essential for Hobbes's (rationalist) view of scientific method. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Did Hobbes Have a Semantic Theory of Truth? WILLEM R. DEJONG 1. INTRODUCTION THE qUESTIONRAISEDin the title of this article may strike the reader as a bit anachronistic. A phrase like 'semantic theory of truth' evokes associations with rather recent developments in logic, especially the work of Alfred Tarski. Nevertheless, it is generally agreed that Hobbes made important observations of a semantical nature. Moreover, in an interesting article still (...) frequently referred to, R. M. Martin has argued that Hobbes "has in mind a clear-cut semantical concept of truth."' Examining Hobbes's semantical ideas somewhat more closely than Martin did, T6rnebohm has given a more precise characterization of Hobbes's view on truth and falsity; he speaks of Hobbes's comprehension theory of truth. ~One of the main purposes of this article is to investigate whether such a theory is correctly attributed to Hobbes. For Tarski 'true' and 'false' are predicates of (declarative) sentences) But this is not enough to speak of a semantic theory of truth: The leading idea behind Tarski's fundamental work in the field of semantics is (a restricted version of) the principle of compositionality. This principle, also known as Frege's principle, says that the semantic value of a (complex) expression is a function of the semantic values of the syntactic (and categorematic) parts it is ' R. M. Martin, "On the Semantics of Hobbes," Philosophyand PhenomenologicalResearch 14 095314): 2o5-11, esp. ~o7, 211. Cf. I. C. Hungerland and G. R. Vick, "Hobbes's Theory of Language, Speech and Reasoning," in ThomasHobbes:Computatwsire Logica--Logic, translated and commentary by A. Martinich, ed. and introduced by I. C. Hungerland and G. R. Vick (New York: 1981), 15--167, esp. 17, 121-22. 9 H. T6rnebohm, "A Study in Hobbes' Theory of Denotation and Truth," Theor~a26 (196o): 53-7o; see p. 66. 3 A.

Moreover, in the case of linguistic expressions which are (deciarative ) sentences this semantic value should be its truth-value. 4 As we shall see, Hobbes's theory of propositions is basically a theory of subject-predicate propositions. It is therefore reasonable to qualify his theory of truth as a semantic one only if it satisfies Frege's principle to a certain extent. Ideally, this means that the truth-value of subject-predicate propositions should be conceived as a function of the semantic interpretations of its subject and predicate. In the next three sections I will concentrate principally on the logicosyntactical aspects of language. I will then discuss successively the general structure of propositions, the various sorts of names, and the syntax of Hobbes's theory of propositions. Section 5 is devoted to Hobbes's theory of truth as interpreted by Martin and T0rnebohm. The outcome of this examination makes it necessary to break away from Martin's restricted conception of semantics. Martin, like Tarski, takes semantics as "semantics in the narrower sense," i.e., as the discipline Quine refers to as the theory of reference. 5 However, sometimes this term is used in a broader sense; the field of semantics is taken then to include the theory of meaning too. Although the wording differs frequently, the distinction between meaning and reference is almost a constant in the history of thinking about language. On the side of meaning one finds terms like connotation, intension, conception, signification and analyticity, while terms like naming, denoting, extension (and sometimes again signification) are ]inked to the notion of reference. In the Computatio sive Logica, the first part of De Corpore, containing Hobbes's most mature work on the philosophy of language, this opposition is displayed by way of a distinction between, on the one side, nominare, denotare and appellare and, on the other side, significare. Hobbes's view of the significative, as opposed to the denotative, role of linguistic expressions is treated in sections 6, 7, and 8. There it will be shown that Hobbes's radical nominalism is decisive for his doctrine of signification; moreover, this nominalism raises serious problems for the relation... (shrink)

Notwithstanding its overwhelming descriptive power for existing data, it is not clear whether the kinematic theory of Plamondon & Alimi could generate new insights into biomechanical constraints and psychological processes underlying the way organisms trade off speed for accuracy. The kinematic model should elaborate on the role of neuromotor noise and on biomechanical strategies for reducing endpoint variability related to such noise.

According to the grammar of Port-Royal it is possible to convert the noun ‘homme’ into the adjective 'humain' by adding a confused signification or connotation. Strangely enough it is stipulated that by the reversal of this process the adjective 'human' is converted into the substantive ‘humanité’ rather than the original noun ‘homme’. In this article I argue that the treatment of adjectives and substantives in the Port-Royal grammar depends strongly on the traditional Aristotelian ontology as summarized in the so-called ontological (...) square and the theory of the predicables. In connection with this it is shown that according to the Port-Royalists corresponding concrete and abstract nouns like ‘homme’ and ‘humanité’, should be in some sense equivalent. (shrink)

Een poging om de geschiedenis van een denkwijze door de eeuwen heen, in dit geval die van het schema van “het midden- en middellijkheidsdenken” , resp. het “denken in termen van ‘midden’ en ‘bemiddeling’” , kritisch in kaart te brengen valt op het eerste gezicht onder het genre Ideengeschichte of history of ideas. Zeker wanneer men ideeëngeschiedenis enerzijds enger, maar anderzijds daarbinnen weer breder opvat dan de invulling die Arthur Lovejoy daaraan gaf in zijn bekende The Great Chain of Being (...) .Het enerzijds betreft de inperking tot het terrein van de filosofie. Het anderzijds raakt hetgeen als idea wordt geaccepteerd. Lovejoy spreekt over ideeën vaak als “unit ideas” en vergt dat deze eenvoudig en ook enkelvoudig zijn. Ik zou in de ideeëngeschiedenis ook ruimte willen maken voor meer complexe filosofische noties, schema’s en zelfs filosofische theorieën. Wel lijkt me dat moet worden vastgehouden aan de eis dat deze ideeën naspeurbaar zijn door filosofische stromingen heen en dat zij bij voorkeur een zekere breedheid vertonen, ook in de zin van toepassing blijken te vinden in meerdere deelgebieden van de filosofie. En hier zij alvast maar genoteerd dat ook Van der Hoeven Lovejoy en diens studie noemt. (shrink)

Many analytical studies purporting to aid decision-making are produced and yet their contribution to actual decision-making is questioned. This article focuses on how institutional structures influence the way analytical information is actually used. A variation of information criterion for quality of decision-making is developed and used to analyze what types of structures incite actors to both generate and store a variety of ideas and arguments. An international comparison on transport infrastructure planning is used to demonstrate the relevant institutional mechanisms and (...) how different structures lead to different processes of information exchange and to differing product outcomes.

The original, Dutch version of this book served in 1979 as a doctoral disserta tion in philosophy at the Free University in Amsterdam. In this preface to the - slightly revised - English translation, I wish once again to express my gratitude to my supervisors, Prof. J. van der Hoeven of the Free University and Prof. G. Nuchelmans of the University of Leiden, for their excellent and stimulating support. Professor van der Hoeven was associated with this project from the outset. (...) It was a privilege to benefit from his incisive commentaries, especially in those instances where the objective was to break through to more fundamental insights. I shall not lightly forget his friendly and heartening encouragement. I am equally grateful for my discussions with Professor Nuchelmans. I almost always tried to follow his advice, since it was based upon awesome expertness and erudition. I am happy to have found in the person of Herbert Donald Morton, Th.M., M.A., an able and enthusiastic translator. Drs. Gerben Groenewoud made the translations of a number of the Latin citations. I acknowledge permission from Routledge and Kegan Paul and the University of Toronto Press to quote from The Collected Works of John Stuart Mill. And I thank the Netherlands Organization for the Advancement of Pure Research (Z.W.O.) for fmancing this translation. (shrink)
