Practical realism is focused on the problem of how science really works. In the case of physics and chemistry, experiment is the centrepiece of scientific practice. The rapid development of contemporary natural science does not leave the experiment unaffected. The classical experiment is normally applied only to systems that can be considered structurally stable, repeatability being the key feature. After the introduction of the theoretical basis of irreversibility by Ilya Prigogine the essence of the experiment changed. The strict requirement of (...) repeatability has to be dropped. It will be discussed, whether the change is big enough for calling it revolutionary. There are means to update the understanding of the experiment by applying the experimental settings. The material experiment will probably be with us forever but its position on the scientific landscape will be shifted. (shrink)

This is an attempt to take a look at chemistry from the point of view of practical realism. Besides its social–historical and normative aspects, the latter involves a direct reference to experimental research. According to Edward Caldin chemistry depends on our being able to isolate pure substances with reproducible properties. Thus, the very basis of chemistry is practical. Even the laws of chemistry are not stable but are subject to correction. At the same time, these statements do not necessarily make (...) Edward Caldin a predecessor of practical realism. The latter has other predecessors, like Rom Harré’s policy realism or Sami Pihlström’s pragmatic realism. Chemistry is an experimental science. The experiment is a purposeful and critically theory-guided constructive, manipulative, material interference with nature according to Rein Vihalemm, the founder of practical realism. Chemistry is physics-like science but just partly so. This is an important point in the context of the current paper. (shrink)

Artificial intelligence is developing rapidly. There are technologies available that fulfil several tasks better than humans can and even behave like humans to some extent. Thus, the situation prompts the question whether AI should be granted legal person- and/or agenthood? There have been similar situations in history where the legal status of slaves or indigenous peoples was discussed. Still, in those historical questions, the subjects under study were always natural persons, i.e., they were living beings belonging to the species Homo (...) sapiens. We analyse the situation from moral-ethical and practical perspectives. The final conclusion is that the currently existing AIs are still so far removed from humans that there is simply no need to think seriously about legal person- or agenthood. Doing so would mean imposing obligations on the AI to follow. This, in turn, would mean that certain rights in relation to those obligations would have to be granted as well. By all evidence, this is something that humans are not ready to do yet and might never get that far. (shrink)

The paper deals with the philosophy of science and technology from a new perspective. The analysis connects closely to the novel approach to scientific research called practical realism of the late Estonian philosopher of science and chemistry Rein Vihalemm. From his perspective, science is not only theoretical but even more clearly a practical activity. This kind of practice-based approach puts chemistry rather than physics into the position of the most typical science as chemistry has a dual character resting on both (...) constructive-hypothetico-deductive and classifying-historico-descriptive types of cognition. Chemists deal with finding out the laws of nature just like the physicists do. However, in addition to this chemistry deals with substances or stuff that is rather an activity typical to natural history. The analysis of the dual character of chemistry brings forward the need to analyse philosophically also the reasons why physics has held the position of the model science so far. The problem unfolds in the context of practical realism. However, some earlier observations concerning the dual character of chemistry influenced us as well, i.e. by Friedrich Paneth, Michael Polanyi and Edward Caldin. More recently, Bernadette Bensaude-Vincent and Jonathan Simon have given their own explanation of why and how chemistry has a dual character. From their perspective, chemistry is a perfect technical science as it aims at applications, literally at producing something new. Bensaude-Vincent and Simon call their approach operational realism. The latter, however, does not differ from practical realism. (shrink)

This paper presents a survey of the philosophy of science in Estonia. Topics covered include the historical background (science at the 17th century Academia Gustaviana, in the 19th century, during the Soviet period) and an overview of the current situation and main areas of research (the problem of demarcation, a critique of the traditional understandings of science, φ-science, classical and non-classical science, the philosophy of chemistry, the problem of induction, the sociology of scientific knowledge, semiotics as a methodology).

For decades, the British philosopher of science Nicholas Maxwell has been promoting a new approach to science called aim-oriented empiricism. Maxwell's basic claim is that the regular way of doing science, called standard empiricism, is untenable because it does not account for the basic general assumptions that scientists actually adhere to without acknowledgment. Standard empiricism is unable to make sense of the progress of science as it is happening. The alternative approach that Maxwell advocates, aim-oriented empiricism, acknowledges some basic metaphysical (...) assumptions, comprehensibility, unity and simplicity as inherent parts of science itself. By including these metaphysical assumptions into science, Maxwell is looking for ways to make sense of the progress of science from a philosophical perspective. This paper challenges Maxwell's claim with the help of another new approach to science, practical realism. While the founder of practical realism, Rein Vihalemm, claims that his approach is closely related to Maxwell's views, he does not acknowledge any need for metaphysics in science. (shrink)

Edmund Husserl believed that he had a method in phenomenology, which could be systematically applied. The essence of the method concerned the so-called “bracketing” of the objects outside of our consciousness. Husserl elaborated his idea through the conception of reductions, which he divided into eidetic,transcendental and phenomenological ones. The conception has recently been carefully analyzed by Dagfinn Føllesdal, an outstanding analytical thinker. But he had do admit that Husserl was not consistent in applying his method. Definitely, the core of Husserl’s (...) phenomenology can be studied using the analytic method. However, this does not mean that we can speak about applying a method in the case of Husserl himself. We get somewhat closer to a clearly defined method when we apply the priority argument of Merleau-Ponty for making the method of a phenomenological thinker intelligible. This helps us to clarify that what is being bracketed in phenomenology is the idea of the world embraced by traditional philosophical theory. What we are left with after the reduction is a reformedunderstanding. (shrink)

Nonclarity around the understandingof the concept of chaos has caused someconfusion in the contemporary natural science.For instance, not making a clear distinctionbetween the deterministic and quantum chaos hasmade it impossible to evaluate the approach ofIlya Prigogine in an appropriate way. It isshown that Jean Bricmont has missed the targetin his critique of I. Prigogine's ideas, as thelatter has concentrated his interest on systemsconsisting of infinite (arbitrarily large)number of particles in incessant mutualimpact, the former on systems that have afinite (not necessarily (...) large, althoughsometimes very large) number of particles,which move freely of any mutual impact orparticipate only in transient interaction. Thedifference may sometimes be quite crucial. Itis also suggested that if we consider theirreversibility as the basic element ofdescription of physical world, the world oftrajectories and wave functions cannot beresearched apart from this real irreversibility.

The open-access peer-reviewed journal Acta Baltica Historiae et Philosophiae Scientiarum has been published for two years by now. During this time, the journal has found its place in the field of the history and philosophy of science.

As an idealist, Gottfried Wilhelm Leibniz could not recognize anything corporeal as substantial. However, under the influence of Cartesian terminology, he devoted considerable effort to analysing the corporeal world, while not recognizing its real substantiality of course. Leibniz took the concept of substance from Plato, Aristotle and the scholastics, but developed it in two ways. It is a well-known fact that Leibniz introduced the term ‘corporeal substance’ in his letter to Antoine Arnauld dated to October 1687. In the letter, Leibniz (...) understands an object of nature, like an animal or a plant, as ‘corporeal substance’. In the very same letter, Leibniz introduces the terms ‘indivisibility’ and ‘phenomenon’. Every corporeal substance can be real only as a unity, i.e. by being indivisible. Such entity must have a soul or at least an entelechy. In an opposite case, that entity would not be a real unity but just a phenomenon. No corporeal entity is indivisible and therefore not a substance. The paper aims at introducing Leibniz’s distinction between substances and phenomena and taking a closer look at the historicalphilosophical influences Leibniz experienced while developing his views of the corporeal world. Aristotle and Descartes will receive most of the attention, of course, as the concepts of ‘entelechy’ and ‘hylomorphism’ were introduced by the former, and the understanding of corporeal substance as determined by extension alone is part of the latter. The core of the original critique by Leibniz takes off from the properties of the continuum as well as the nature of shape, motion and extension. The case of continuum will receive special attention. It is analysed with the help of the novel approaches by Samuel Levey and Vassil Vidinsky. Leibniz was critical about our poor understanding of the continuum but his own interpretation of it was not fully consistent either. Although the new developments enable us to take a fresh look that has not been possible so far, the issue remains open for further study. (shrink)
