Modern Philosophy of Science has not yet recognized the significance of physical invariance principles for science and daily life. In this paper we investigate as a simple example, how time independence or time translational invariance of natural laws determines the time scale. We start with informal definitions of the invariance of concepts and laws. We then ask if time independence is an essential feature of natural laws or if time dependent laws are plausible without loss of predictive relevance. In section (...) 3 we investigate the question wether time independence of natural laws is a matter of convention. In sections 5-7 the determination of the time scale by time translational invariance is studied. In section 8 we study the conditions under which this determination is unique. (shrink)

Summary In the last decade analytical philosophy of science has been considered by many people as a descriptive activity. In part I of this paper we show that philosophy of science has been designed as normative logical analysis by Reichenbach and Carnap before world war II. Thus the identification analytical = descriptive is historically unjustified. In part II we discuss three tasks of analytical philosophy of science, the logical reconstruction of concepts, theories, and methods. While the first is mainly descriptive, (...) the third mainly normative, the second may be both, depending on the intended goal. (shrink)

The concept of necessity plays a central role in Kant's philosophy, but seems to lead to severe paradoxes. On the one hand he states: ‘Notwendigkeit und strenge Allgemeinheit sind sichere Kennzeichen einer Erkenntnis a priori’. On the other hand he talks also about ‘notwendig (d. i. nach einer Regel)’, which means ‘necessary according to the empirical natural laws’. However, he never states explicitly the distinction between these two different concepts of necessity. Either Kant's philosophy is inconsistent or we have to (...) assume that he indeed interchanges two different concepts, even if he does not tell us that there is a difference between synthetic apriori necessity and natural necessity. This paper defends the hypothesis of two different necessities and then shows how this strategy makes possible a rational reconstruction of Kant's epistemology. (shrink)

These arguments are fairly well known today. It is interesting to note that v. Kries already knew them, and that they have been ignored by Reichenbach and v. Mises in their original account of probability.2This observation leads to the interesting question why the frequency theory of probability has been adopted by many people in our century in spite of severe counterarguments. One may think of a change in scientific attitude, of a scientific revolution put forward by Feyerabendarian propaganda- and who (...) would deny that Reichenbach was an excellent propagandist!My suggested explanation is the following:J. v. Kries is still a mentalist in the tradition of Descartes and Locke. This can be shown very well from his logic, which he wrote even much later (1916). A mentalist does not pose semantical questions in a proper sense: he rather asks which ideas in the human mind make up a concept. And studying probability in this way, he will find in any case that what is in the human mind is first of all an expectation. Therefore, his analysis of the concept of probability will be centered around the concept of expectation.People tended to approach the problem in quite a different way after the scientific revolution which led from mentalism to lingualism. They tended in many cases to use operationalism and to ask how probabilities are determined in science, if they wanted to clear up the meaning of probability. This new aspect of probability, which was caused by looking at it from a new position or standpoint, suggested it to be the limit of relative frequencies in the first instance. This suggestion was so strong that all objections were ignored, and all counterarguments encountered deaf ears.Of course I have used here an oversimplification. Neither was J. v. Kries untouched by Poincaré's conventionalism, which is essentially a movement leading to the breakdown of mentalism; nor was Reichenbach, when he wrote his thesis in 1915, already a lingualist in any respect.Nevertheless, I think that the lingualist revolution, which took place particularly in mathematics and physics, has also changed the attitude towards probability. It would be interesting to corroborate this thesis by extensive study of the history of science in the late 19th century.Besides this historical aspect of v. Kries' theory, there is a systematic one which should be noticed. Though his theory still has a mentalist outlook, many of v. Kries' statements can be translated into the present lingualist idiom and then become most interesting contributions to the present discussion. We shall then state that for v. Kries probabilities appear first of all in probabilistic hypotheses which may or may not be confirmed by empirical data. Therefore, they have a role similar to theoretical concepts.3But that is not the only predominant feature of v. Kries' theory. He is approaching objective probability in a way which is quite unfamiliar to present day philosophers or mathematicians. Objective probabilities are connected with other concepts in three different ways. First of all, probabilistic hypotheses are confirmed by empirically found relative frequencies in a finite series of events. Secondly, they serve as an aid for decisions. And finally, there is a third relationship. Probabilities have to be explained by theories which are in many cases not formulated in probabilistic terms themselves. We can try to understand probability in one of the first two ways via their connection to other concepts. That is what is usually done by interpretations in terms of frequencies or decisions. A third approach, however, is to understand the nature of probability by the way probabilities are explained, and that is what v. Kries does. Such an approach does not seem unusual at all. In many cases the nature of a kind of objects is characterized by giving an explanation. If somebody asks what an eclipse of the moon is, we shall answer - as Aristotle already proposed - by giving an explanation of it. Thus it is quite natural to answer a question as to the nature of probability by describing the general type of explanation of probability distributions in natural or social science. The answer given by v. Kries is - as we know today — of limited validity. Quantum mechanical probabilities are not explainable by Spielräume. V. Kries solution, however, is remarkable in one important respect. It accounts for the time direction of objective probabilities, which are always predictive or forward probabilities, while retrodictive or backward probabilities are always subjective. The relation of objective probabilities to time direction is surely of utmost importance for natural philosophy. I do not know of any other philosophical foundation of probability which takes into account this deep-rooted relation. Therefore, v. Kries' interpretation may help us to understand one of the most intricate puzzles of philosophy. It may be nearly one hundred years old, but is by no means out of date. (shrink)

Hans Reichenbach's 1928 thesis of the relativity of geometry has been misunderstood as the statement that the geometrical structure of space can be described in different languages. In this interpretation the thesis becomes an instance of trivial semantical conventionalism, as Grünbaum calls it. To understand Reichenbach correctly, we have to interpret it in the light of the linguistic turn, the transition from thought oriented philosophy to language oriented philosophy, which mainly took place in the first decades of our century. Reichenbach (...) — as Poincaré before him — is undermining the prejudice of thought oriented philosophy, that two propositions have different factual content, if they are associated with different ideas in our mind. Thus Reichenbach prepared the change to language oriented philosophy, which he also accepted later. (shrink)

Summary Some leading ideas of the constructivist protophysics are discussed on the basis of P. Janich's Protophysik der Zeit. After having reviewed the contents of the second edition Janich's claim that analytical philosophy of science is purely affirmative and not critical towards science in its historical appearence is refuted. In the next section the principles of constructivist methodology of physics are criticised, and the claim is refuted that prescriptions for measurement cannot without circularity be shown to be invalid by experimental (...) results. In the last section we discuss Janich's foundation of time measurement in a mathematical frame similar to that for extensive systems. Thus the relation between Janich's and the ordinary account is cleared up. (shrink)

Operational definitions were once considered the backbone of semantics of natural science. Still in 1955 A. W. Burks published an explication of the general scheme of these definitions. In the fifties of the last century however they became outmoded, while high school teachers for presumably good reasons were still in favour of them. I consider the banishment of this kind of definitions premature, and try to improve the explication of Burks in a way which qualifies them for a rehabilitation. In (...) the improved explication the concept of intrinsic property becomes important, for which I give a new definition on the basis of a structuralist account of physical processes. German Die operationalen Definitionen galten einst als der Kern der Semantik der Naturwissenschaft. Eine letzte Explikation des allgemeinen Schemas der operationalen Definitionen hat A. W. Burks noch 1955 vorgelegt. In den fünf ziger Jahren kamen sie indessen aus der Mode, während sie noch weiterhin von Gymnasiallehrern - wohl aus berechtigten Gründen - geschätzt wurden. Ich halte die Verbannung dieser Art von Definitionen für voreilig und versuche die Explikation von Burks in einer Weise zu verbessern, dass man sie wieder in der Wissenschaftstheorie rehabilitieren kann. In der verbesserten Explikation wird der Begriff der inneren Eigenschaft eines Dinges oder Vorgangs wichtig, den ich auf der Basis einer strukturalistischen Darstellung physikalischer Vorgänge neu definieren möchte.

The determination of the meaning of theoretical terms by the axioms of theories as meaning postulates and the merely fictitious character of a basic observational language leads to Feyerabends problem of the incommensurability of physical theories. Different theories are actually compared by physicists as well. They might have a common sub-language as the language of macroscopic physics in atomic physics. Furthermore shared metalaws define an equivalence relation which identifies terms of different theories and enables physicists to talk about them in (...) a common language. (shrink)

The aim of this paper is to discuss how far physics differs frommathematics, and if a philosophy of science which uses mathematics or logicsas a model for physics would be unable to be aware of many importantfeatures of that natural science.Many functions in physics differ from those of mathematics in beingfunctional dependecies and in having a lawlike character.Physical quantities have the character of "`determinables"'', sets ofspecial entities which are presupposed by physical theories.One may suspect that physics also could not be (...) formulated in anextensional language. This cannot be true, however, since every language canbe translated into an extensional version. Neverthless the existence ofdeterminables in physics shows that physics does not only talk aboutconcrete entities like space, time, spacetime, and particles, but also aboutvalues of abstract sets like determinables, and that it thus acknowledgestheir existence.

In an illuminating article A. Kamlah considers philosophy of science as an activity leading step by step from neutral descriptions to rational prescriptions. What his remarks do not offer us is a way of dealing with the troublesome ambiguities we find in the analyses provided by those philosophers of science who refuse to say whether they legislate how scientists should behave or describe how they do. In this context I want to draw attention to a helpful distinction H. A. (...) Simon has made. (shrink)

A student's future as a knowledge worker (one who "thinks for a living" with the task of problem solving) is the starting point of this book. With this in mind, the book combines a review of philosophical positions and problems with practical examples and perspectives gained from everyday challenges faced by knowledge workers in their businesses and organizations. Through the use of summative chapters, highlighted key concepts, questions for reflection, and illustrative examples on how to work with the theories presented, (...) the book provides a clear and accessible introduction to this challenging subject. Philosophy of Science primarily addresses students studying language, communication, marketing, economics, and management. However, the survey of the theoretical schools of thought - as well as the discussions on research ethics and the role of research in society - will be equally relevant for other students in the humanities and the natural and social sciences.

In their paper, Romanis and Adkins delve into the potential impact of artificial amnion and placenta technology (AAPT) on cases of pregnancy loss1 that do not involve procreative loss. First, they call for more recognition of the negative feelings a person might have due to the premature end of their pregnant state. They claim that, should AAPT minimise concerns about prematurity as anticipated, individuals might feel pressured to opt for partial ectogestation to preserve their or their fetus’ well-being; moreover, they (...) point out that the feelings of loss in the context of AAPT are likely to be worse than the ones reported in neonatal intensive care units cases. Finally, they advocate for care pathways focusing on how the transfer of a fetus to the AAPT could affect the pregnant person, with particular attention to managing the grief potentially caused by the pregnancy loss. I praise the authors for such a call to action—especially since partial ectogestation is expected to become a reality in the short-term future—and I share their demands for additional and more attentive care of (formerly) pregnant patients. However, I am concerned that their approach is so focused on negative feelings towards pregnancy loss that it risks becoming …. (shrink)

Traditionally, the manufacturer/operator of a machine is held (morally and legally) responsible for the consequences of its operation. Autonomous, learning machines, based on neural networks, genetic algorithms and agent architectures, create a new situation, where the manufacturer/operator of the machine is in principle not capable of predicting the future machine behaviour any more, and thus cannot be held morally responsible or liable for it. The society must decide between not using this kind of machine any more (which is not a (...) realistic option), or facing a responsibility gap, which cannot be bridged by traditional concepts of responsibility ascription.

Neural devices have the capacity to enable users to regain abilities lost due to disease or injury – for instance, a deep brain stimulator (DBS) that allows a person with Parkinson’s disease to regain the ability to fluently perform movements or a Brain Computer Interface (BCI) that enables a person with spinal cord injury to control a robotic arm. While users recognize and appreciate the technologies’ capacity to maintain or restore their capabilities, the neuroethics literature is replete with examples of (...) concerns expressed about agentive capacities: A perceived lack of control over the movement of a robotic arm might result in an altered sense of feeling responsible for that movement. Clinicians or researchers being able to record and access detailed information of a person’s brain might raise privacy concerns. A disconnect between previous, current, and future understandings of the self might result in a sense of alienation. The ability to receive and interpret sensory feedback might change whether someone trusts the implanted device or themselves. Inquiries into the nature of these concerns and how to mitigate them has produced scholarship that often emphasizes one issue – responsibility, privacy, authenticity, or trust – selectively. However, we believe that examining these ethical dimensions separately fails to capture a key aspect of the experience of living with a neural device. In exploring their interrelations, we argue that their mutual significance for neuroethical research can be adequately captured if they are described under a unified heading of agency. On these grounds, we propose an “Agency Map” which brings together the diverse neuroethical dimensions and their interrelations into a comprehensive framework. With this, we offer a theoretically-grounded approach to understanding how these various dimensions are interwoven in an individual’s experience of agency. (shrink)

Wittgenstein’s and Heidegger’s objections against the possibility of a science of aesthetics were influential on different sides of the analytic/continental divide. Heidegger’s anti-scientism leads him to an alētheic view of artworks which precedes and exceeds any possible aesthetic reduction. Wittgenstein also rejects the relevance of causal explanations, psychological or physiological, to aesthetic questions. The main aim of this paper is to compare Heidegger with Wittgenstein, showing that: there are significant parallels to be drawn between Wittgenstein’s and Heidegger’s anti-scientism about aesthetics, (...) and that their anti-scientism leads both towards partly divergent criticisms of what I will call ‘aestheticism’. The divergence is mainly due to a broader metaphilosophical disagreement concerning appeals to ordinary language. Thus situating the two philosophers’ positions facilitates a possible critical dialogue between analytic and continental approaches in aesthetics. (shrink)

Anche se siamo comunemente abituati a pensare alla scienza come a un qualcosa di assolutamente atemporale e indipendente da tutto, in realtà essa è profondamente influenzata dalla cultura e dalla società del tempo in cui vive. Infatti né la scienza è isolabile dalla società, né la società è isolabile dalla scienza, tanto meno come si sta configurando oggi. Per approfondire questi aspetti, esistono però due visioni antagoniste che bisogna superare: secondo la visione scolastica, retaggio del positivismo ottocentesco ancora molto diffuso (...) fra scienziati e pubblico di non esperti, la scienza è conoscenza senza soggetto conoscente. All'opposto, la visione cinica della scienza, sull'onda di talune elaborazioni della sociologia della scienza, la riduce a nient'altro che a una costruzione di soggetti che partecipano al gioco scientifico, una cultura come altre e da "mediare", e comunque una conoscenza relativa, se non frutto di una costruzione puramente soggettiva, arbitraria, ideologica. Un'analisi della costituzione sociale della scienza può, invece, mirare a un'indagine scientifica sulla scienza proprio configurando una relatività della conoscenza che supera sia l'assolutismo idealistico sia il relativismo soggettivistico.

The problem of intentional inexistence arises because the following (alleged) intuitions are mutually conflicting: it seems that sometimes we think about things that do not exist; it seems that intentionality is a relation between a thinker and what such a thinker thinks about; it seems that relations entail the existence of what they relate. In this paper, I argue for what I call a radical relationist solution. First, I contend that the extant arguments for the view that relations entail the (...) existence of their relata are wanting. In this regard, I defend a kind of pluralism about relations according to which more than one kind of relation involves non-existents. Second, I contend that there are reasons to maintain that all thoughts are relations between thinkers and the things they are about. More accurately, I contend that the radical relationist solution is to be preferred to both the intentional content solution (as developed by Crane) and the adverbial property solution (as developed by Kriegel). Finally, I argue that once the distinction between thinking “X” and thinking about X has been drawn, the radical relationist solution can handle issues like ontological commitment, substitutivity failure, scrutability, and non-specificity.

In recent years, Brentano’s theory of consciousness has been systematically reassessed. The reconstruction that has received the most attention is the so-called identity reconstruction. It says that secondary consciousness and the mental phenomenon it is about are one and the same. Crucially, it has been claimed that this thesis is the only one which can make Brentano’s theory immune to what he considers the main threat to it, namely, the duplication of the primary object. In this paper, I argue that (...) the identity reconstruction is untenable, and I defend an alternative, which I name the unity reconstruction. According to the unity reconstruction, secondary consciousness is a real part of the mental phenomenon it is about, and hence is distinct from it. I contend that this thesis does not in itself lead to the duplication of the primary object, and that what should be blamed is rather a controversial thesis about the intentional structure of secondary consciousness—a thesis which Brentano ultimately abandoned.

In A Matter of Principle, Ronald Dworkin discusses the role a political morality should play in decisions about when the law should be obeyed and enforced, and even what law is. Noticing that liberalism was once a quasi-consensus theory in Great Britain and the United States – and, therefore, a natural candidate to that role in those countries – Dworkin argues that the loss of that status is due to an alleged failure of liberal political theorists to identify a kind (...) of egalitarianism as the constitutive principle on which liberalism is based. My aim in this paper is to advance arguments against such an influential claim that a certain egalitarianism would be the constitutive principle of political liberalism. (shrink)

As a positive thesis, philosophical anarchism claims that political authority is always at odds with practical rationality insomuch as authoritative directives are best analysed as content-independent reasons. The aim of this paper is to clarify the metaethical assumptions behind such a claim. Since philosophical anarchists reject as irrational the possibility that an agent can follow content-independent reasons issued by another agent, emphasising agents’ responsibility to assess the content of every directive before acting in conformity with it, it is safe to (...) say that philosophical anarchists must be cognitivist in metaethics. At the very least, were there no right or wrong answers to questions such as “what does one have reason to do in these circumstances?”, answers such as “one should follow authoritative directives” would be as good as any other. However, philosophical anarchism requires much more than metaethical cognitivism; indeed, it requires a very specific (and ambitious) type of cognitivism. I intend to show which one. (shrink)

It is safe to say that the main line of criticism against the reading of Critical Philosophy as Transcendental Semantics is that Kant would be concerned about semantic problems only on Critique of Pure Reason so that such reading would not make sense beyond that work. In this paper, I describe Transcendental Semantics in short words and analyze at length Kant’s theory of concepts on Transcendental Analytic of Critique of Pure Reason in order to make a suggestion: every concept has (...) to attend the demands of Transcendental Semantics to be called a concept in critical sense.A principal linha da crítica contra a leitura da filosofia crítica como semântica transcendental afirma que Kant teria trabalhado sobre problemas semânticos apenas na Crítica da razão pura, assim sendo, não faria sentido ultrapassar esse limite com aquela intepretação.

This paper develops the idea that valid arguments are equivalent to true conditionals by combining Kripke’s theory of truth with the evidential account of conditionals offered by Crupi and Iacona. As will be shown, in a first-order language that contains a naïve truth predicate and a suitable conditional, one can define a validity predicate in accordance with the thesis that the inference from a conjunction of premises to a conclusion is valid when the corresponding conditional is true. The validity predicate (...) so defined significantly increases our expressive resources and provides a coherent formal treatment of paradoxical arguments. (shrink)

In this paper we re-assess the philosophical foundation of Exactly True Logic ($$\mathcal {ET\!L}$$ ET L ), a competing variant of First Degree Entailment ($$\mathcal {FDE}$$ FDE ). In order to do this, we first rebut an argument against it. As the argument appears in an interview with Nuel Belnap himself, one of the fathers of $$\mathcal {FDE}$$ FDE, we believe its provenance to be such that it needs to be taken seriously. We submit, however, that the argument ultimately fails, (...) and that $$\mathcal {ET\!L}$$ ET L cannot easily be dismissed. We then proceed to give an overview of the research that was inspired by this logic over the last decade, thus providing further motivation for the study of $$\mathcal {ET\!L}$$ ET L and, more generally, of $$\mathcal {FDE}$$ FDE -related logics that result from semantical analyses alternative to Belnap’s canonical one. We focus, in particular, on philosophical questions that these developments raise. (shrink)

Friedrich Nietzsche was among the figures from the history of nineteenth century philosophy that, perhaps surprisingly, some of the Vienna Circle’s members had presented as one of their predecessors. While, primarily for political reasons, most Anglophone figures in the history of analytic philosophy had taken a dim view of Nietzsche, the Vienna Circle’s leader Moritz Schlick admired and praised Nietzsche, rejecting what he saw as a misinterpretation of Nietzsche as a militarist or proto-fascist. Schlick, Frank, Neurath, and Carnap were in (...) different ways committed to the view that Nietzsche made a significant contribution to the overcoming of metaphysics. Some of these philosophers praised the intimate connection Nietzsche drew between his philosophical outlook and empirical studies in psychology and physiology. In his 1912 lectures on Nietzsche, Schlick maintained that Nietzsche overcame an initial Schopenhauerian metaphysical-artistic phase in his thinking, and subsequently remained a positivist until his last writings. Frank and Neurath made the weaker claim that Nietzsche contributed to the development of a positivistic or scientific conception of the world. Schlick and Frank took a further step in seeing the mature Nietzsche as an Enlightenment thinker. (shrink)
