Non-empirical principles have always been a subject of interest of philoso-phers. Authors from different times and traditions agree that principles such as analogy or simplicity are present in the scientific practice. The disagreement comes out when these authors affirm that these principles have an epistemic function, and when they try to present reasons in order to found this state-ment. The first goal of this paper is to describe these principles and to point out their methodological importance. The second goal is (...) to introduce the discussion between the two most important models of philosophical fundamentation – it means, the logicism and the psychologism. The last goal – the main one – is to defend that the non-empirical principals have, legitimately, an epistemic role in the scientific investigation. (shrink)

The paper exposes the principal procedures of assessing methodological theories. The first one is based on a consensus about the aims of science, the second uses epistemological criteria, and the third checks the adequacy of methodological requirements against the history of science. This third procedure is singled out for a more detailed treatment. It is argued that rational reconstruction constitutes a separate level of historiography and concerns historical explanation. The subject of a rational reconstruction is the methodological explanation of all (...) basic value judgments, whereas all additional factors are not determined by methodological rules. It is further specified in which way rationally reconstructed history should correspond to the actual course of historical events, i. e. to which extent rational reconstruction is free to interpret history according to methodological categories. In the last paragraph the connection between scientific progress and the growth of knowledge is discussed. (shrink)

In this paper, I argue that Imre Lakatos’s account on the relation between the history and the philosophy of science, if properly understood and also if properly modified, can be valuable for the philosophical comprehension of the relation between the history and the philosophy of science. The paper is divided into three main parts. In the first part, I provide a charitable exegesis of the Lakatosian conception of the history of science in order to show that Lakatos’s history cannot be (...) a caricature. In the second part, I describe what I believe are the real problems of Lakatos’s account on a metaphysical and on a methodological level. In order to address these problems, I take advantage of the recent critique of the so-called “confrontation model”. Finally, in the third part, I suggest that a proper modification of Lakatos’s perspective can resolve the aforementioned problems without distorting Lakatos’s central aspiration, which is that the philosophical theories of scientific rationality can be assessed with the help of the history of science without losing their normative content.

Three fundamental claims are defended in this dissertation. First, the influence of Hume's epistemological program and his skepticism with respect to causal knowledge have hindered the development of an adequate theory of scientific explanation. Second, Hume's conception of causal knowledge is outdated, and knowledge of causation should be relieved of the special epistemological burden placed on it by Hume's followers. Finally, once relieved of this Humean epistemological burden, the causal theory of scientific explanation is superior to alternatives lying in the (...) tradition of Humean positivism. ;Humean positivism places severe constraints on theories of scientific explanation, and its influence on extant theories is reviewed. Recent positivist theories of scientific explanation are discussed critically, and are shown to suffer serious difficulties. Particular attention is paid to recent pragmatic theories and to Kitcher's unificationist theory. ;The causal theory of scientific explanation is developed through an examination of theories of causation. Traditional views , recent statistical theories, and Salmon's theory of causation are rejected in favor of Cartwright's thesis that causal laws are best understood as capacity ascriptions. The essential features of scientific explanations are then outlined: most prominent are the ascription of causal capacities and the description of causal interactions. The philosophical benefits of the causal theory are also summarized. ;Common objections to causal theories of explanation are treated. Of central importance is Hume's skeptical argument. Once Hume's conception of causal knowledge is modernized, however, his arguments yield no skepticism particular to the knowledge of causation: causal knowledge is as defensible as are more respectable types of empirical knowledge. Other important objections are also reviewed. ;Finally, historical studies of two well-known explanatory controversies--the Jensen-Lewontin debate concerning the heritability of IQ, and a dispute about the nature of cosmic radiation--are presented. Positivist theories of scientific explanation can account for neither the origin nor the manner of resolution of these controversies. In contrast, the causal theory of explanation is shown to illuminate the controversies successfully. This success offers additional evidence in favor of the causal theory of scientific explanation.

General discussions of the appropriate relations between history and philosophy of science must be complemented by examinations of particular studies involving both fields. Martin Curd's attempt to illuminate the rationality of theory change through analysis of the Copernican Revolution is such a study; his work is undercut by serious flaws and actually displays an ahistorical approach. The result misleads both about the Copernican Revolution and the general problem of theory change in science. The study does illustrate several types of failing (...) that can vitiate efforts to bring historical considerations into philosophical discussion, namely, pitfalls in the characterization of theories, arguments, range of choices, and criteria.

Despite having put the concept of HPS on the institutional map, N.R. Hanson’s distinctive account of the interdependence between history of science and philosophy of science has been mostly forgotten, and misinterpreted where it is remembered. It is argued that Hanson’s account is worthy of renewed attention and extension since, through its special emphasis on a variety of different normative criteria, it provides the framework for a fruitful and transformative interaction between the two disciplines. This essay also examines two separate (...) threads of Hanson’s account of philosophy of science: his analysis of the conceptual dynamics of science and of the interrelation of the history and philosophy of science. While the two strands appear incongruent, and were perhaps inconsistent, a new interpretation of them is offered which is both consistent with Hanson’s fundamental intuitions and defensible in its own right. It is demonstrated that Hanson’s account compares favorably with those of Kuhn and Lakatos, and that it may provide a constructive means of scaling the barriers erected by fears of the genetic fallacy and ‘whiggish’ history.
