Discusses the philosophy of science and the process of scientific discovery, and looks at ethical issues such as genetic engineering, prolonging life through technology, and the role of the physician.

Stove argues that Popper and his successors in the philosophy of science, Kuhn, Lakatos and Feyerabend, were irrationalists because they were deductivists. That is, they believed all logic is deductive, and thus denied that experimental evidence could make scientific theories logically more probable. The book was reprinted as Anything Goes (1998) and Scientific Irrationalism: Origins of a Postmodern Cult (1998).

In the late 19th century great changes in theories of light and electricity were in direct conflict with certitude, the view that scientific knowledge is infallible. What is, then, the epistemic status of scientific theory? To resolve this issue Duhem and Poincaré proposed images of fallible knowledge, Instrumentalism and Conventionalism, respectively. Only in 1919–1922, after Einstein's relativity was published, he offered arguments to support Fallibilism, the view that certainty cannot be achieved in science. Though Einstein did not consider Duhem's Instrumentalism, (...) he argued against Poincaré's Conventionalism. Hitherto, Einstein's Fallibilism, as presented at first in a rarely known essay of 1919, was left in the dark. Recently, Howard obscured its meaning. Einstein's essay was never translated into English. In my paper I provide its translation and attempt to shed light on Einstein's view and its context; I also direct attention to Einstein's images of philosophical opportunism in scientific practice.

I discuss the relevance of the current predicament in cosmology to the debate over scientific realism. I argue that the existence of two, empirically successful but ontologically inconsistent cosmological theories presents difficulties for the realist position.

Philosophical considerations have been essentially involved in the origin and development of the steady-state cosmological theory. These considerations include an explicit uniformitarian methodology and implicit metaphysical views concerning the status of natural laws in a changing universe. I shall examine the foundations of SST by reconstructing its early history. Whereas the strong uniformitarian methodology of SST found no support in the subsequent development of cosmology, the idea of a possible influence the global structure of the universe may have on the (...) laws of physics operative in it has been assimilated by the standard big bang theory as it made its remarkable progress in recent decades.

A Brief History of Time: From the Big Bang to Black Holes is a popular-science book on cosmology (the study of the origin and evolution of the universe) by British physicist Stephen Hawking. It was first published in 1988. Hawking wrote the book for readers who have no prior knowledge of the universe and people who are interested in learning.

'I want to begin by declaring that I regard scientific knowledge as the most important kind of knowledge we have', writes Sir Karl Popper in the opening essay of this book, which collects his meditations on the real improvements science has wrought in society, in politics and in the arts in the course of the twentieth century. His subjects range from the beginnings of scientific speculation in classical Greece to the destructive effects of twentieth century totalitarianism, from major figures of (...) the Enlightenment such as Kant and Voltaire to the role of science and self-criticism in the arts. The essays offer striking new insights into the mind of one of the greatest twentieth century philosophers. (shrink)

The eminent mathematical physicist Sir Hermann Bondi once said: “There is no more to science than its method, and there is no more to its method than Popper has said.” Indeed, many regard Sir Karl Raimund Popper the greatest philosopher of science in our generation. Much of what Popper “has said” refers to physics, but physicists, generally speaking, have little knowledge of what he has said. True, Popper's philosophy of science and, in particular, his realistic interpretation of quantum mechanics deviates (...) considerably from the generally accepted doctrine. But as Popper, rightly I think, points out, it is precisely the proliferation of divergent theories which promotes the growth of scientific knowledge; it would be a danger for physics if physicists were dogmatically tied to a single theory or would not test their theory against alternatives. It is for this purpose that, on the occasion of the nonagenarian celebration of Popper's birthday, the present essay has been written. (shrink)

The essays in this volume represent an approach to human knowledge that has had a profound influence on many recent thinkers. Popper breaks with a traditional commonsense theory of knowledge that can be traced back to Aristotle. A realist and fallibilist, he argues closely and in simple language that scientific knowledge, once stated in human language, is no longer part of ourselves but a separate entity that grows through critical selection.

The observations which are compatible with temporal origins of the earth, the solar system and the universe are briefly mentioned, prior to examining the assumptions implicit in the hypothesis of temporal origin which the observations were designed to test. No decisive observation enables us to distinguish between theories of a temporal origin of the universe and the theories of infinite time (continuous creation); the aspects of the galaxies offer no test of either theory without invoking additional assumptions. Curvature of time (...) is rejected as being a complication at present scientifically unnecessary, as is also the hypothesis of continuous creation. The view maintained is that the temporal theory based on linear extrapolation is acceptable until it be disproved. Various new techniques which may be useful in attempting to refute this theory are discussed. (shrink)

On the basis of his unpublished thesis ‘Gewohnheit und Gesetzerlebnis in der Erziehung’ a historical reconstruction is given of the genesis of Popper's ideas on induction and demarcation which differs radically from his own account in Unended quest. It is shown not only that he wholeheartedly endorses inductive epistemology and psychology but also that his ‘demarcation’ criterion is inductivistic. Moreover it is shown that his later demarcation thesis arises not from his worries about, on the one hand, Marxism and psychoanalysis (...) and, on the other hand, Einstein's physics, but rather from his urgent preoccupation with providing pedagogy with a psychological foundation, which has its sources in Karl Bühler's cognitive psychology as well as, surprisingly, Adler's Characterology. Aside from Adler some lesser known psychologists, such as Karl Groos, will also be seen to have played a formative role on Popper's early thinking. (shrink)

Time magazine's "Man of the Century", Albert Einstein is the founder of modern physics and his theory of relativity is the most important scientific idea of the modern era. In this short book, Einstein explains, using the minimum of mathematical terms, the basic ideas and principles of the theory that has shaped the world we live in today. Unsurpassed by any subsequent books on relativity, this remains the most popular and useful exposition of Einstein's immense contribution to human knowledge. With (...) a new foreword by Derek Raine.

In the form in which it was originally expounded, the anthropic principle was presented as a warning to astrophysical and cosmological theorists of the risk of error in the interpretation of astronomical and cosmological information unless due account is taken of the biological restraints under which the information was acquired. However, the converse message is also valid: biological theorists also run the risk of error in the interpretation of the evolutionary record unless they take due heed of the astrophysical restraints (...) under which evolution took place. After an introductory discussion of the ordinary ('weak') anthropic principle and of its more contestable ('strong') analogue, a new application of the former to the problem of the evolution of terrestrial life is presented. It is shown that the evidence suggests that the evolutionary chain included at least one but probably not more than two links that were highly improbable (a priori) in the available time interval.

This article examines in detail a remarkable but short-lived cosmological theory of 1959. The theory depended crucially on a hypothesis that could be, and was, tested in the laboratory. I use the case to discuss the nature of testing in cosmology and to argue against ideas about astronomy suggested by Ian Hacking. The case of the electrical universe exemplifies how disagreements can be settled by good experiments and also how experiments of wide-ranging theoretical significance need not be biased by either (...) theory or the experimentalists’ predisposed ideas. I argue that the episode supports Allan Franklins “evidence model” and disputes accounts based on the sociology of scientific knowledge. (shrink)

The various cosmological proposals by Einsteinian relativists seek to show the structure of the world as a consequence of the basic notions of relativity. In particular, the irrelevance of the state of motion of an observer to his description of the fundamental laws of nature is to be maintained. Furthermore, gravity is understood as being a description of the fact that particles move along certain minimal paths in non-Euclidean space. In this theory, the effect of one material particle on another (...) particle in the old-fashioned sense of gravitational attraction becomes indirect; that is, a particle moves on a minimal path in a space having a degree of curvature dependent on the material entities which exist in it, rather than having its path bent by the attraction between it and other material bodies, all of them existing in an absolute or receptacle-like space.

Why did Einstein tirelessly study unified field theory for more than 30 years? In this book, the author argues that Einstein believed he could find a unified theory of all of nature's forces by repeating the methods he used when he formulated general relativity. The book discusses Einstein's route to the general theory of relativity, focusing on the philosophical lessons that he learnt. It then addresses his quest for a unified theory for electromagnetism and gravity, discussing in detail his efforts (...) with Kaluza-Klein and, surprisingly, the theory of spinors. From these perspectives, Einstein's critical stance towards the quantum theory comes to stand in a new light. This book will be of interest to physicists, historians and philosophers of science.

One of the more important cosmological consequences of Einstein's general theory of relativity is the hypothesis that our universe may either expand or contract with time. Relativistic cosmogony is concerned with those phases of this process which belong to the past. We begin with a digest of cosmogonic developments.

This work inaugurates a critical inquiry into whether the ideas of Karl Popper, a philosopher of science, are used by astronomers and astrophysicists, a practicing community of scientists. It examines four basic components of Karl Popper's philosophy— falsification, prohibition, simplicity, and risk taking— and the extent that these themes become integrated into recent scientific literature on astronomy, astrophysics, cosmology, and stellar evolutionary theory. It concludes that the philosophy of science is highly relevant to the practice of astronomy, and that Karl (...) Popper plays a unique role in directing different communities of astronomers and cosmologists. (shrink)

Summary During the 1930 and 1940s, the small world of cosmologists was buzzing with philosophical and methodological questions. The debate was stirred by Edward Milne's cosmological model, which was deduced from general principles that had no link with observation. Milne's approach was to have an important impact on the development of modern cosmology. But this article shows that it is an exaggeration to intimate, as some authors have done recently, that Milne's rationalism went on to infiltrate the discipline.
