A reductionistic, bottom‐up, cellular‐based concept of the origins of sentience and consciousness has been put forward. Because all life is based on cells, any evolutionary theory of the emergence of sentience and consciousness must be grounded in mechanisms that take place in prokaryotes, the simplest unicellular species. It has been posited that subjective awareness is a fundamental property of cellular life. It emerges as an inherent feature of, and contemporaneously with, the very first life‐forms. All other varieties of mentation are (...) the result of evolutionary mechanisms based on this singular event. Therefore, all forms of sentience and consciousness evolve from this original instantiation in prokaryotes. It has also been identified that three cellular structures and mechanisms that likely play critical roles here are excitable membranes, oscillating cytoskeletal polymers, and structurally flexible proteins. Finally, basic biophysical principles are proposed to guide those processes that underly the emergence of supracellular sentience from cellular sentience in multicellular organisms. (shrink)

This book assembles recent research on memory and learning in plants. Organisms that share a capability to store information about experiences in the past have an actively generated background resource on which they can compare and evaluate coming experiences in order to react faster or even better. This is an essential tool for all adaptation purposes. Such memory/learning skills can be found from bacteria up to fungi, animals and plants, although until recently it had been mentioned only as capabilities of (...) higher animals. With the rise of epigenetics the context dependent marking of experiences on the genetic level is an essential perspective to understand memory and learning in organisms. -/- Plants are highly sensitive organisms that actively compete for environmental resources. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate information and then modify their behavior accordingly. -/- The book will guide scientists in further investigations on these skills of plant behavior and on how plants mediate signaling processes between themselves and the environment in memory and learning processes.

Úspěšná kniha MUDr. Františka Koukolíka Mocenská posedlost se vrací na knižní trh v novém vydání, od základu přepracovaná a doplněná bohatou věcnou dokumentací. Fenomén moci od prvního vydání knihy (Karolinum 2011) zdá se posílil a více prorostl mnoha, prakticky všemi oblastmi života populace na planetě Zemi. Nové zpracování problému se opírá o čísla statistik, o interpretaci každodenních událostí ve světě, o výsledky anket a psychologických experimentů, nepomíjí ani autorovu doménu – neurovědu jako zdroj poznání nejniternějších lidských podnětů i úchylek. Metodou (...) pohledu je ovšem vždy kritický rozum. Skrze něj a v širokých souvislostech podává autor obraz světa, který je stále více varující. (shrink)

Study of Hans-Georg Gadamer's and Julius Stenzel's interpretations of Plato.

Advances in Pig Welfare analyses current topical issues in the key areas of pig welfare assessment and improvement. With coverage of both recent developments and reviews of historical welfare issues, the volume provides a comprehensive survey of the field. The book is divided into two sections. Part I opens with an overview of main welfare challenges in commercial pig production systems and then reviews pig welfare hot spots from birth to slaughter. Part II highlights emerging topics in pig welfare, such (...) as pain and health assessment, early socialisation and environmental enrichment, pig-human interactions, breeding for welfare, positive pig welfare and pigs as laboratory animals. This book is an essential part of the wider ranging series Advances in Farm Animal Welfare, with coverage of cattle, sheep, pigs and poultry. With its expert editor and international team of contributors, Advances in Pig Welfare is a key reference tool for welfare research scientists and students, veterinarians involved in welfare assessment, and indeed anyone with a professional interest in the welfare of pigs.

"In "Captive of Freedom," Dr. Spinka concentrates on Berdyaev's basic tenets, particularly those aspects of his thought which constitute his unique contribution to religious philosophy." -- From dust cover.

The paper proposes a solution to the problem of counterfactuals, building on both Rescher’s epistemic and Tichý’s semantic approaches. The core of the proposed solution is the thesis that when expressing a true counterfactual, the speaker assumes a set of background indicative premises as an implicit parameter. When added tacitly to an unreal antecedent, these premises entail the consequent logically or analytically. We draw a distinction between a potentially unreal and an absolutely unreal condition expressed in the antecedent. We view (...) counterfactuals with a positive time vector and an absolute unreal condition as abbreviated deductive retrodictions. Similarly, we consider counterfactuals with a potentially unreal condition to be abbreviated deductive predictions. In a similar manner, we also explain the truth (falsity) of vacuously true counterpossibles or counterpossible conditionals. In the second part, we discuss the enigmatic backtracking counterfactuals. We propose that their negative time direction is due to their being abductive retrodictions, i.e., explanations of unreal effects based on possible causes in which the conditions remain tacit or unexpressed. The backtracking temporal direction of counterfactual abductive retrodictions is in accordance with the thesis on the positive temporal direction from cause to effect. Thus, we demonstrate that in order to explain backtracking counterfactuals, there is no need to assume violations of laws of nature or a special logic. What we need to do is to take into account the third parameter, i.e., a set of tacit or unexpressed additional propositions, as well as the principle of ceteris paribus as the background. (shrink)

Táto štúdia ponúka stručné uvedenie do sokratovskej otázky, pričom sa v nej kladie dôraz predovšetkým na Platónovho Sókrata. Prvá časť príspevku sleduje vznik sókratovskej otázky v antike. V druhej časti sa pojednáva o vzostupe Platónovej autority v riešení tejto otázky. Nasledujúca časť podáva argumenty, prečo je Platónov portrét Sókrata z pohľadu historika filozofie neudržateľný a nedôveryhodný. Navrhované riešenia sókratovského problému spočívajú v zdržaní sa úsudku o historickej autentickosti Platónovho Sókrata.

A review of Lubomír Doležel´s Possible Worlds of Fiction and History: The Postmodern Stage (Baltimore: Johns Hopkins University Press, 2010, 171 pp. ISBN 978-0-8018-9463-3).

The paper deals with the state of the social sciences after the boom of internet services in the Czech Republic in the 1990s. The results of our survey, based on 512 responses from the economics and history departments of major Czech public universities, show that internet services are considered a quality factor for academic output; however, the issues of plagiarism, a lack of resource criticism, inadequacy of impact factor-based evaluations, poor academic training for the new generation of social scientists, the (...) failure of state academic policy, and the generation gap make further development in the Czech social sciences rather problematic. As a result we recommend creating a better communication link between policy makers and scholars, reforming the current state policy which encourages lower quality academic output, and improving academic training, which requires a more individual approach, and also placing higher demands on social scientists.

Cellular circadian clocks represent ancient anticipatory systems which co‐evolved with the first cells to safeguard their survival. Cyanobacteria represent one of the most ancient cells, having essentially invented photosynthesis together with redox‐based cellular circadian clocks some 2.7 billion years ago. Bioelectricity phenomena, based on redox homeostasis associated electron transfers in membranes and within protein complexes inserted in excitable membranes, play important roles, not only in the cellular circadian clocks and in anesthetics‐sensitive cellular sentience (awareness of environment), but also in the (...) coupling of single cells into tissues and organs of unitary multicellular organisms. This integration of cellular circadian clocks with cellular basis of sentience is an essential feature of the cognitive CBC‐Clock basis of cellular life. (shrink)

It is common opinion that relation between the Aristotelian logic and logic of the Stoic is either complemental or rival. In his analysis, the author criticize claim according to which the Stoic examples of conclusions do not contained universal statements. He is showing that they expressed universal statements standard across implication and by anaphoric connection of pronouns. For this reason it is necessary to revise interpretation of basic, so called unprovable inferring rules of the Stoic. These rules are for predicate (...) logic and their interpretation, as propositional rules, is just special case. On the base of revised rules the author proved through Stoic logical system all valid modes of the first syllogistic figure of Aristotelian categorical syllogism. He also concludes that Aristotelian logic was just fragment of evidently more strong Stoic logic. (shrink)

The similarity between logic and semantics of the Stoics and Frege has long been known, and it can be explained in various ways. In 2021, Susane Bobzien published a work in which she explains this similarity rather surprisingly: she hypothesizes that Frege generously helped himself with the foundations of Stoic logic as it was published in the first volume of History of Logic in the West by Carl Prantl. However, this hypothesis encounters various problems. The key point of the whole (...) accusation is founded on the formulation of a general propo-sition in language using implication and anaphora, which Frege supposedly took from the Stoics, although in Prantl’s text there is only one example of a sentence with this structure. On the contrary, there are many examples of such sentences in contemporary professional (e.g. legal) texts. Many examples of semantic simi-larities that Bobzien presents are based only on the similarities between isolated concepts; however, that is regularly the case for such concepts with the same conceptual basis. Bobzien presents a significant number of matches only on the basis of results that could allegedly be inferred from the texts. However, this cannot be considered a proof of plagiarism. Bobzien does not consider many sources for the continuity of interpretation such as the so-called hypothetical syllogism found in available textbooks of logic. Last but not least, her claims do not consider many differences between Stoic and Frege’s logic. All this leads us to the conclusion that Bobzien does not present sufficient facts and connections between them that would confirm her hypothesis about Frege’s plagiarism of the Stoic logic: Frege simply was not a plagiarist.

Oceanic languages typically make a grammatical contrast between expres- sions of alienable and inalienable possession. Moreover, further distinctions are made in the alienable category but not in the inalienable category. The present research tests the hypothesis that there is a good motivation for such a development in the former case. As English does not have a grammaticalized distinction between alienable and inalienable possession, it provides a good testing ground. Three studies were conducted. In Study 1, participants were asked to write (...) down the first interpretation that came to mind for possessive phrases, some of which contained inherently relational possessums, while o thers contained possessums that are not inherently relational. Phrases with non-relational possessums elicited a broader range of interpretations and a lower consistency of a given interpretation across possessor modifiers than those with relational possessums. Study 2 demonstrated that users assign a default interpretation to a possessive phrase containing a relational possessum even when another reading is plausible. Study 3, a corpus-based analysis of possessive phrase use, showed that phrases with relational possessums have a narrower range of interpretations than those with other possessums. Taken together, the findings strongly suggest that grammatical distinctions between different types of alienable possession are motivated. (shrink)
