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)

Creative Class, Creative Economy, and the Wisdom Society as a Solution to their Controversy The paper briefly introduces the notion of creativity, linking the concepts of creative class and the related creative economy that are considered by Florida and his followers as the driving force of the current social and economic development. The concept of creative economy and its quantification in form of the Creative Class Index 3T or the Euro-Creativity Index were submitted to strong critique.The critics overturn some key (...) issues of the concept of creative class with an indication that the creative people give priority in choosing the work from the place; and there is no or almost nil correlation of a perceptual representation of the persons of homosexual orientation and the high-tech growth which confirms the opinion that the assertion about higher creativity of homosexual persons is a myth only. The purpose of the article is the examination of propriety of the concept of creative class and its quantification at one hand, and the rightfulness of their critique at the other. The analysis of the axiology of the concept of creative class is the method of examination. From point of view of axiology probably the most significant characteristic of the creative class is its accompanying destruction of thee social capital of creative people and it substitution of the creative capital. The rise of creative class takes place in parallel with the implosion of values at which basis our Jewish-Christian civilization is established. To this Florida expresses rather vague attitude by a statement that all socio-cultural changes that accompany the rise of the creative class will have no favorable impact on society.Florida labeled creativity as a basic human law, furthermore, he announced the need for a new live style in which the quality of life will increase and people become better men. The concept of creativity as an instrument of urban planning evolved into a left-liberal ideology with elements of social engineering that is the most important finding of the axiological analysis. The second finding is the need to accept the meaning of creativity. By implication of the two findings there arises a proposal for wisdom as a new driving force of social and economic development. The conclusion is the contribution is a requirement for formulation of the concept of wisdom society that is currently likely absent in the academic world, and the statement that if the West will not create the wisdom society, it will lose the raison d'être of its existence.

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)

Úvahy spojené s náhodností se v evropské historii objevují poměrně pozdě, na přelomu středověku a novověku. Týkají se zpočátku šancí výhry v různých hrách či situacích a později přecházejí k zavedení pravděpodobnosti klasické a geometrické. Počet pravděpodobnosti je z matematického hlediska završen Kolmogorovovou axiomatickou teorií. Ve způsobu vnímání a interpretace pravděpodobnosti však přetrvává mnoho otevřených otázek, problémů a paradoxů, jako například řešení Bertandovy úlohy. Čtyři hlavní směry v pojetí pravděpodobnosti (logické, četnostní, subjektivní a propenzitní) úzce souvisejí se způsobem vnímání náhodnosti (...) (epistemologickým nebo ontologickým). Úvahy o vývoji vnímání náhodnosti a interpretace pravděpodobnosti přinášejí schopnost orientovat se v základních principech a poznatcích vědy a přispívají k hlubšímu pochopení celé problematiky.

Polarity is an inherent feature of almost all prokaryotic and eukaryotic cells. In most eukaryotic cells, growth polarity is due to the assembly of actin‐based growing domains at particular locations on the cell periphery. A contrasting scenario is that growth polarity results from the establishment of non‐growing domains, which are actively maintained at opposite end‐poles of the cell. This latter mode of growth is common in rod‐shaped bacteria and, surprisingly, also in the majority of plant cells, which elongate along the (...) apical–basal axes of plant organs. The available data indicate that the non‐growing end‐pole domains of plant cells are sites of intense endocytosis and recycling. These actin‐enriched end‐poles serve also as signaling platforms, allowing bidirectional exchange of diverse signals along the supracellular domains of longitudinal cell files. It is proposed that these actively remodeled end‐poles of elongating plant cells remotely resemble neuronal synapses. BioEssays 25:569–576, 2003. © 2003 Wiley Periodicals, Inc. (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.

Plants are sessile, highly sensitive organisms that actively compete for environmental resources both above and below the ground. They assess their surroundings, estimate how much energy they need for particular goals, and then realise 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 behaviour accordingly. These highly diverse competences are made possible by parallel sign(alling)-mediated communication processes within the plant (...) body (intraorganismic), between the same, related and different species (interorganismic), and between plants and non-plant organisms (transorganismic). Intraorganismic communication involves sign-mediated interactions within cells (intracellular) and between cells (intercellular). This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated plant parts. This allows plants to coordinate appropriate response behaviours in a differentiated manner, depending on their current developmental status and physiological influences. Lastly, this volume documents how plant ecosphere inhabitants communicate with each other to coordinate their behavioural patterns, as well as the role of viruses in these highly dynamic interactional networks.

"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.

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)

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)
