Starting with some illustrative examples, I develop a systematic account of a specific type of experimentation--an experimentation which is not, as in the "standard view", driven by specific theories. It is typically practiced in periods in which no theory or--even more fundamentally--no conceptual framework is readily available. I call it exploratory experimentation and I explicate its systematic guidelines. From the historical examples I argue furthermore that exploratory experimentation may have an immense, but hitherto widely neglected, epistemic significance.

: The increasing attention on experiment in the last two decades has led to important insights into its material, cultural and social dimensions. However, the role of experiment as a tool for generating knowledge has been comparatively poorly studied. What questions are asked in experimental research? How are they treated and eventually resolved? And how do questions, epistemic situations, and experimental activity cohere and shape each other? In my paper, I treat these problems on the basis of detailed studies of (...) research practice. After presenting several cases from the history of electricity—Dufay, Ampère, and Faraday—I discuss a specific type of experiment—the "exploratory experiment"—and analyze how it works in concept formation. I argue that a fuller understanding of experiment can only be achieved by intertwining historical and philosophical perspectives in such a way that the very separation of the two become questioable.

Combining philosophical and historical scholarship, the articles in this volume focus on scientific concepts, rather than theories, as units of analysis. They thereby contribute to a growing literature about the role of concepts in scientific research. The authors are particularly interested in exploring the dynamics of research; they investigate the ways in which scientists form and use concepts, rather than in what the concepts themselves represent. The fields treated range from mathematics to virology and genetics, from nuclear physics to psychology, (...) from technology to present-day neural engineering. The volume contains articles by Vassi Kindi, Miles MacLeod, Ingo Brigandt, Friedrich Steinle, Dirk Schlimm, Theodore Arabatzis, Uljana Feest, Corinne Bloch, Mieke Boon, Nancy Nersessian, and Hanne Andersen.

Faraday's view of the mutual relation of speculative theories and laws of nature implies that there should be a procedure, leading from speculative considerations to a system of facts and laws in which theories do no longer play any role. In order to make out the degree in which Faraday's claims correspond to his practice, the way in which he gains an explanation of Arago's effect is analyzed. The thesis is proposed that he indeed has a procedure of leaving theories (...) aside. It is intimately connected with certain methodological guidelines of his experimentation. (shrink)

This volume thus clears the ground for the productive and fruitful integration of these new developments into philosophy of science.

The authors provide an overview of philosophical discussions about the roles of experiment in science. First, they cover two approaches that took shape under the heading of “new experimentalism” in the 1980s and 1990s. One approach was primarily concerned with questions about entity realism, robustness, and epistemological strategies. The other has focused on exploratory experiments and the dynamic processes of experimental research as such, highlighting its iterative nature and drawing out the ways in which such research is grounded in experimental (...) systems, concepts and operational definitions. Second, the authors look at more recent philosophical work on the epistemology of causal inference, in particular highlighting discussions in the philosophy of the behavioral and social sciences, concerning the extrapolation from laboratory contexts to the world.

The more unknowns there are and the newer a field of research is, the less well defined are the experiments. Once a field has been sufficiently worked over so that the possible conclusions are more or less limited to existence or nonexistence, and perhaps to quantitative determination, the experiments will become increasingly better defined. But they will no longer be independent, because they are carried along by a system of earlier experiments and decisions, which is generally the situation in physics (...) and chemistry today. Such a system will then become self-evident know-how itself. We will no longer be aware of its application and effect (Fleck 1935 (1980), p. 114, translation slightly altered from Fleck 1979, p. 86, original emphasis). (shrink)

Knowledge about colour it properties, methods of fabrication, meanings, and uses has always been the purview of a wide range of individuals, from painters and architects to dyers, printers, pigment manufacturers, chemists. This volume discusses how different communities interacted with respect to knowledge and practices surrounding colour, thus contributing to a better understanding of an important current in cultural history.".

[First paragraph] A widespread image of science is founded upon a basic dichotomy: there are empirical facts, obtained by observation and experiment, on the one hand, and theories and explanations, obtained by reasoning, speculation and creativity, on the other. Whether scientific reasoning should take the inductive path, or the hypothetical-deductive approach, has long been a mat-ter of debate, but the basic dichotomist picture has been left untouched. And there is the concomitant idea that theories may come and go, while facts (...) form the stable, unshaken and ever growing foundation of science. This picture is often advanced in science education, for example in experimental physics courses and their textbooks. Additionally, the use of lan-guage reinforces that picture: we say that we "discover" facts (such as the cosmic micro-wave background, the variability of species), while we create, form and eventually discard theories (like the standard model of elementary particles, string theory, theories of develop-mental biology and so on). Something that has been "discovered" is attributed a different status than something that has been created and formed. (shrink)

The term “virtual entities” has a long tradition and a variety of meanings. My short article focuses on one particular meaning, as clearly defined by Charles Sanders Peirce in 1902. I will discuss the definition he provided and touch on the wide resonance it had and still has in science.

Knowledge and the History of Science. This essay asks how the object of history of knowledge could be delineated so as to keep it distinct from the history of science (that has always dealt with knowledge) and, at the same time, to keep it specific enough not to turn into a general history of all human activities. By way of discussing the type of knowledge we could call ‘scientific’, and arguing that history of science should take an integrative approach, I (...) propose that a history of knowledge should focus on generalizing accounts taken in most various domains and cultures.

That science is more than the unilinear application of general theories to specific empirical circumstances is, one hopes, no longer something that is controversial or requires detailed argument. To be sure, there were times when devising universally applicable theories was seen as the most worthy task of science, with less lofty activities such as experimentation and scientific modeling being relegated to the underbelly of “proper science.” Arguing for a pluralistic recognition of the diversity of scientific practices, methods, and goals, might—at (...) least on the pages of this journal—amount to preaching to the converted. Yet, once the diversity and heterogeneity of science is acknowledged, the real work only starts:... (shrink)

“Supposing that truth is a women-what then?” This is the very first sentence in Nietzsche’s Beyond Good and Evil . Not very often are philosophers so disarmingly explicit in their intention to discomfort the reader. In fact, one might say that the natural state of Nietzsche’s reader is one of perplexity. Yet it is in the process of overcoming the perplexity that one realizes how rewarding to have one’s ideas challenged. In Beyond Good and Evil, Nietzsche critiques the mediocre in (...) modernity and challenges the reader to accept their state of becoming and accept improvisation and creativity of the process. Nietzsche’s book is carefully designed to disorient the reader, to systematically provoke and tease her to the point of stealing away her certainties. It is challenging yet rewarding to overcome the perplexities of Nietzsche’s teachings. (shrink)

Published posthumously in 1908, Ecce Homo was written in 1888 and completed just a few weeks before Nietzsche’s complete mental collapse. Its outrageously egotistical review of the philosopher’s life and works—featuring chapters called Why I Am So Wise and Why I Write Such Good Books—are redeemed from mere arrogance by masterful language and ever-relevant ideas. In addition to settling scores with his many personal and philosophical enemies, Nietzsche emphasizes the importance of questioning traditional morality, establishing autonomy, and making a commitment (...) to creativity. Essential reading for students of philosophy, this unique memoir is crucial to an understanding of Nietzsche’s other works. (shrink)

Never one to back away from controversy, Friedrich Nietzsche assails the Christian church in Twilight of the Idols. In this classic work, he sets out to substitute the morality of the Catholic and Protestant churches with that of Dionysian morality. Twilight of the Idols furthermore lays the foundation for key arguments that Nietzsche more fully develops in later writings.

A work of Nietzsche's later years, The Antichrist was written after Thus Spoke Zarathustra and shortly before the mental collapse that incapacitated him for the rest of his life. The work is both an unrestrained attack on Christianity and a further exposition of Nietzsche's will-to-power philosophy so dramatically presented in Zarathustra. Christianity, says Nietzsche, represents "everything weak, low, and botched; it has made an ideal out of antagonism towards all the self-preservative instincts of strong life." By contrast, Nietzsche defines good (...) as: "All that enhances the feeling of power, the Will to Power, and power itself in man. What is bad?-All that proceeds from weakness. What is happiness?-The feeling that power is increasing,-that resistance has been overcome." In attempting to redefine the basis of Western values by demolishing the formative influence of the Judeo-Christian tradition, The Antichrist has proved to be highly controversial and continuously stimulating to later generations of philosophers.

The Origin of the Family, Private Property and the State (1884), was a provocative and profoundly influential critique of the Victorian nuclear family. Engels argued that the traditional monogamous household was in fact a recent construct, closely bound up with capitalist societies. Under this patriarchal system, women were servants and, effectively, prostitutes. Only Communism would herald the dawn of communal living and a new sexual freedom and, in turn, the role of the state would become superfluous.
