On the ground of the empirical data, the present paper was to find out whether there is any interrelationship between intensity of religious attitude and personality traits defined as predispositions to particular interpersonal behaviours in social situations, as well as to determine the extent of the phenomenon. By intensity of religious attitude one means the strength and determination with which the individual abides by his attitude.The intensity was tested by means of the Religious Attitude Scale designed by the author (Prężyna). H. G. Gough’s Psychological Inventory (California Psychological Inventory) in its Polish version (translated by Z. Płużek) standarized on the Polish population and compiled by the Psychometric Workshop of the Polish Academy of Sciences (B. Markowska, A. Kottas) was employed in the personality tests. The tests were carried out in 1972 upon higher school graduates between twenty-one years and thirty five (arts graduates — 38 per cent, science graduates — 62; per cent).The interrelationship between religious attitude and personality was exploreted through isolation of differences in the personality traits of people with a different level of intensity of religious attitude. Among the latter there were isolated three groups of testees: with high positive intensity (N = 30), with low intensity (N = 30), and with high intensity of negative religious attitude (N = 20). In turn, these groups were tested in respect of personality traits.The received empirical data clearly reveal the interrelationship between both structures. It is evident in the differences in the personality traits discovered in particular groups. The differences between the group revealing high positive intensity and the one characterized by low intensity appeared in the eleven scales: social presence (Sp), responsibility (Re), socialization (So), self-control (Sc), tolerance (To), good impression (Gi), communality (Cm), achievement via conformance (Ac), achievement via independence (Ai), intellectual efficiency (Ie), feminity (Fe). In turn, the differences between the groups with high intensity of positive and negative religious attitude were discovered in the eight scales: capacity for status (Cs), social presence (Sp), responsibility (Re), self-control (Sc), good impression (Gi), achievement via conformance (Ac), flexibility (Fx), feminity (Fe). Finally, the differences between the groups with low intensity and high intensity of negative religious attitude appeared in the three scales: dominaee (Do), achievement via independence (Ai), intellectual efficiency (Ie).Considering the empirical data, the individuals revealing high intensity of positive religious attitude prove in relation to the remaining groups more socially conscious, responsible, self-controlled, persevering. They also reveal greater intensity of these traits (diligence, intellectual efficiency, self-sufficiency) which help to achieve popularity in a social group and to gain its approval. Then, the testees of this group are characterized by the predispositions more connected with feminity (Fe), and therefore they are more delicate, ready to help, subtle, accepting other people. Finally the group reveals high social adjustment achieved mostly through compromise and adaptation to the environment. In turn, the representatives of the group revealing low intensity of religious attitude tend to possess the opposite traits. Therefore, in relation to the previous group, they would be less socially conscious and less responsible, less intellectually efficient, and at the same time more spontaneous and self-confident. The group reveals social maladjustment connected with feeling uncomfortable (low Wb) and a tendency to self-accusation (low Gi). Finally, the group revealing high intensity of negative religious attitude is characterized by activity, self-assurance, greater nonchalance and roughness in contacts with the environment. At the same time they are ingenous, self-sufficient and intellectually efficient. The group seems to be socially adjusted although it achieves this by means of subordination of the environment.At the end it is necessary to point out that the connection between the interpersonal aspect of personality and intensity of religious attitude does not merely concern the single traits but it also reaches deep into the structure of personality.

The Moral Motivation in Various Groups of Youth

The essential aim of the present studies was to answer the question: ”What is the opinion of senior students about moral duties, considering a particular type of motivation?”.The testee was placed in a hypothetical moral situation and ordered to determine the degree of preference of three triads of norms taking into consideration perso- nological, deontological and utilitarian motivation. The ratings were presented on the scale of the degree of acceptance of the behaviour norms, ranging from 0 to 100. In order to determine the degree of preference for each of the motivations, the testee had to compare pairs of norms: ni with n2: nx with n3; n2 with n3. The comparison resulted in three global proportional indices of preferences completing to a hundred, since the testee was to give them for all these situations in which he considered accomplishment of the particular activity necessary.The analysis of the experimental data concerns 150 senior students from five higher schools in Lublin (30 students from each school).A general survey of the medial values of the degree of the motive preference indicates that in the main young people give priority to personological and deonto- logical motivation over utilitarian one.As far as personological motivation is concerned the testees seem to value most the norm: ”to help a person being in danger of losing his life”. The norm also achieved the highest degree of acceptance in the deontological version. In the group of norms of utilitarian motivation the students pronounced themselves in favour of ”to act justly as then one has a clear conscience”.When considering the problem of interdependence between the motivation ratings and the type of higher school it was found out that students of all higher schools equally (preferred norms of deontological motivation. It means that preference of this motivation is independent of the character of the higher school in which the young people are intellectually formed.The type of higher school proved however a significant determinant of the norm preference in respect of personological and utilitarian motivation. The highest degree of preference of utilitarian motivation could be observed in students from agricultural school, while medical students revealed lower degree in the ratings of personological motivation than university students. Besides the analyses of the results proved that the sex variable is not a significant determinant of the ratings of the norm preference in respect of the motivation type.

Motives for Contact with a Group of Religious Character

The discussed studies concern groups of religious character and liturgical interests. The tests were carried out upon two experimental groups of 150 persons being in firm contact with group and 50 persons being in temporary contact with the group, respectively. Their average age was* ca. twenty The studies included also 30 experienced guardians of such groups. The testees answered five questions concerning the motives of contact with a religious and liturgical group, founded on the assumptions of the direct as well as the projection methods.In the group characterized by firm contact the testees on the average state that 43 per cent of their collègues remain in contact with their religious and liturgical group without any deeper experiences or religious motives, The corresponding figure in the other group is 45, and in the guardians (answers) statements, 25.In most answers predominate motives referring to the positive atsmosphere in the group, and to the religiuos experiences (it concerns the answers both to the questions founded on the projection assumptions and the ones employing direct methods, though in reverse order).The difficulties and inhibitions the testees have to overcome and which may testify to the strength of their motivation, very often concern the person of the guardian, particularly in case of persons remaining in temporary contact with the group.In the course of the detailed analysis of the motives a general practical conclusion obviously suggests itself. In groups of religious character it seems absolutely necessary to see not only to the accomplishment of their specific religious tasks, but also to the matters of proper organization and coexistence within the group, both problems being strongly streesed by the tested young people.

Successiveness of Abilities in the Development of Classification Process

Founded on the author’s studies concerning classification of wooden blocks, pictures of animals, and names, the article aims at proving that abilities involved in completion of similar tasks differ with age, and therefore mental level of testees. Notions developed by J. P. Guilford in his theory and model of the intellect structure were employed to interpret results of the studies.The article presents transverse studies of classification in children from four years to fifteen (30 children in each age-group) as well as longitudinal studies concerning acceleration of classification abilities in the situation of experimental training of children from four years to seven (121 children in the main groups, and the same number in control groups).The results indicate certain regularities of the successiveness of abilities. Tasks involving classification of wooden blocks, the correct completion of which demanded operations of converging formation on figurai material, leading to logical classes were completed by the four-year-olds by means of operations of cognition on figurai material, leading to units resembling playing patterns. Tasks, the correct completion of which demanded semantic abilities were completed by the four and five-year-olds by means of figurai abilities. For children from eight years to ten pictures of animals carried simultaneously both semantic and figurai contents. Cards with names of animals often carried symbolic contents for the eight-year-olds (classification according to the ’appearance’ of a name), while in case of the eight, nine, and ten-year-olds semantic contents co-occurred with notional figuration.Acceleration of the abilities development in condition of experimental training proved that at certain stages of development e.g., at the age of four, there existed impassable barriers as far as change of one type of abilities to another was concerned, e.g., figural to semantic abilities.Theoretical importance of the researched problems results from tearing the mechanisms governing both the origin of abilities and change of abilities of one type to another. Practical importance of the problems is apparent in the field of shaping abilities and accelerating their development.

Problem „ciągłości—skokowości” procesu uczenia się na przykładzie procesu identyfikacji pojęć
Continuity vs Discontinuity of the Process of Learning as Revealed in the Process of Concept
view |
rights & permissions
| cited by
The article concerns a particular problem: is the process of learning in simple experimental situations of ’continuous’ or ’discontinuous’ character? For a long time it has been a subject of dispute among psychologists. Spence (1949), Hull (1950), Bush and Morteller (1951), Estes and Burke (1955), Bourne and Restle (1959) pronounced themselves for the continuous theory of learning, while Krechevsky (1932, 1936), Bruner and co-workers (1956), Levine (1959), Estes (1964), Restle (1962), Bower and Trabasso (1964) favoured the discontinuous theory. The results achieved in the properly chosen experimental conditions confirm both opinions. Empirical decision whether learning is continuous or discontinuous constitutes the aim of the discussed studies.Certain assumptions of Bower and Trabasso’s model of concept identification were employed as theoretical tools permitting to settle the problem. The model assumes that in the experiment the sequences of reactions preceding the final error constitute independent Bernuolli samples, i.e., (a) probability of correct reactions preceding the final error remains constant p (the trait is known as the stationary character), (b) probability of a given reaction (either correct or incorrect) is independ of the earlier and later results in examining a sequence of experiments (the trait is known as independence). The expectations were empirically verified.An essential problem of either continuity or discontinuity of the process of concept identification is connected with the question of the stationary and independent character, if in the course of learning probability of a correct reaction p or an incorrect reaction q changes its value (p increases while q decreases) the fact confirme continuity of the process. If, on the other hand, the probability remains constant until the moment of completion, then the process of identification is of discontinuous character.The experiments the results of which are discussed in the article are simple. The subjects had to assign the stimuli to two groups. Each stimulus was characterized by six attributes, and each attribute, by one of the two values. The attributes and their values were as follows: (a) shape of geometrical figures (either a square or a triangle), (b) colour of the figure (either red or green), (c) size (either large or small), (d) thickness of the line (either thin or bold), (e) position of the dot (either above or under the figure), (f) position of the line (either horizontal or vertical). The number of all the possible, mutually differentiating systems of stimuli was 26=64.The stimuli were exposed successively in the order established according to the table of random numbers. After each reaction (accomplished classification of a single card) the subject was informed by the experimenter about either correctness or incorrectness of his reaction. A succession of sixteen correct reactions was considered the criterion of solution (learning).A hundred college students (five groups) were tested. Forty experiments were carried out upon each subject. It was attempted to settle the initially set question of continuity v. discontinuity in different stimulus situations. Group 1 solved the problems in which one attribute only was significant, Group 2 solved the problems in which two attributes were always significant and redundant, Group 3, the problems with three significant, redundant attributes. Group 4 solved the problems where the stimuli possessed one, two or three significant attributes in random order. Groups 4 and 5 solved the same problems, yet subjects from Group 5 were in formed that some of the problems would contain one significant attribute while others would have two or even three, and that different types of problems would appear in random order.Therefore five varieties of experiments were carried out i = l ... p(5): there were five statistical tests (five groups). In each variety forty experiments were carried out and for the pourposes of statistical calculations these were in succession connected into eight classes with five results (experiments) each j = l ... q(8). Two subsamples divided according to sex consituted each statistical test k=l ... r(2). In each sub-group there were ten persons 1 = 1 ... n (10).Since according to Bower-Trabasso’s model stationary and independent character of attempts preceding the solution does not depend on skill (order of experiments) particular results were connected.Results achieved by each person in a single experiment represent sequences of one’s (errors) and zero’s (correct reactions). To decide whether the process generating these sequences is of the stationary character one examines each individual sequence of units and zero’s considering a series of attempts exclusive of the final error, and sub-sequently divides it into two equal parts. Then, correct reactions and errors in each part are summed up. Next, the appropriate halves for all the subjects within particular groups are summed up. In this way it is possible to calculate the number of errors and correct reactions in both the first and the second half for each group and for particular sub-groups.Table 1 presents the number of correct attempts and the number of errors in both halves for all the sub-groups. In both halves of all the series in all the varieties of the experiment there are more correct reactions than errors. It means that probability p (of a correct reaction) is higher than probability q (of an incorrect reaction). The result departs from the one expected by Bower and Trabasso p = 0.5.In nearly all the sub-groups the number of correct reactions in the second half is higher in comparison with the corresponding figures in the first half, although it is different with the number of errors. Table 2 contains a detailed comparison of the received values ^2. The differences (between the number of correct reactions and errors are statistically significant. Values x2 significant at the level .05 are underlined once, those significant at the level .01 are underlined twice. It clearly indicates certain improvement in the manner of solving in the second half of the sequence of attempts, and therefore confirms the hypothesis that the final error is preceded by learning, and in turn shakes the assumption about the stationary character of attempts preceding the final error. Charts 1 to 5 illustrate some of the data from Table 2.The notion that successive reactions preceding the solution are statistically independent constitutes another essential assumption of the model. The matrix of transitions from a correct reaction and an incorrect reaction was completed for each person in order to establish whether the samples were independent. In this way forty cumulated four-field matrices were received. Table 3 presents the x2 values for all the matrices. The results confirm that the action of identification of notions is not a pure stochastic process (it reveals certain trends, e.g., more transitions from correct reactions to correct ones) as in the course of the exercise the process becomes more random. Since according to the model skill should not influence the independence of tests, all the numbers were cumulated in Table 4, and the matrix of transitions for all the 4.000 results was determinedz The yf test for the four-field matrix of transitions (x2=68.35) (P < .01). It obviously indicates that particular samples in the chain of reactions do not satisfy the requirements typical of independent Bernoulli samples. The present article attempts at the interpretation of these differences.

The Decision Model of Information Processing in Situations with a Source of Reliable (Infallible) Information

The article aims at the analysis of a subject’s behaviour in the decision situation with a source of reliable (infallible) information. Notions developed by the statistical theory of decision were employed for the purposes of formal description of the information processing.The optimal decision model was constructed for the information processing of a subject remaining in the decision situation of an experimental type, permitting to determine whether the behaviour of the actual decision-maker fulfilled postulates of the statistical theory of decision.The decision model indicates that information processing (often identified with cognition) results from a complex of decisions. To its elements belong among others, decision of initiation, the function of which is to accomplish the primary information cycle, as well as form positive attitude towards continuation of subsequent cycles ; decision of continuation constituting the basis for undertaking subsequent information cycles : signiferent decisions, realizing a definite course of signifirent decisions according to certain strategy.Subsequently, formally characterized elements of the decision complex constituted point of reference for the analysis of behaviour of the actual decision-makers, in this case children from eight years to fifteen. The decision model permitted to observe the course of information processing in the experimental situation of the type where a decision is made in the conditions permitting influx of reliable (infallible) information on the state of affairs.In the course of analysis of the experimental data from the point of the model behaviour some determinants of the testees’ decisions were established.It was observed, among others, that nearly all the children made the initiation decision which was the necessary condition of realizing information processing in the experimental situation. Age of the testees and the factor of learning proved important determinants of this decision.On the other hand, as far as the continuation decision was concerned, it was established that with growth of uncertainty of situation the testees tended to increase successively the number of information cycles. Yet, the fact that increse in uncertainty of situation from five to six hypotheses does not result in further increase in the number of cycles permits to assume that in situations of this type uncertainty of up to five hypotheses ( —log2 1 5 bits) constitutes the subjective limit of the direct influence of the degree of uncertainty upon the decision of continuation.Besides, statistical analyses proved that the number of undertaken information cycles depended on the shape of matrices upon which the ’’treasure” was situated, although it was independent of the order of their exposition in the experiment.Finally, one should observe that the attempt at the formal description of the subject’s behaviour in the experimental situation by means of notions developed by the statistical theory of decision not only permitted the experimenter to observe the testee’s behaviour in a more thorough manner, but also indicated the heuristic values of the procedure.

Measurement of the Utility of Activities in the Decision Situations

Experimental studies in the ’roulette’ type situations differing in the probability of occurence of particular events (the needle coming to rest on either green or blue compartment of the disc) were carried out upon 313 persons from eight years to fifteen. The testees played against the experimenter having previously established the sum of money they staked on the events on "their” smaller blue compartment. The experimenter played on the green compartment with a set stake of 1p.The results of the experiments permit to observe that in the situations with a relatively high probability of occurence of the desired event (the needle coming to rest on the blue compartment) the testees tend to underestimate the utility of activities in their decisions. On the other hand, when the probability is lower than 1/5 the testees, on the average, choose stakes lower than the optimum ones, they overestimate the utility of their activities.Also with the development of the testees the tendency to overestimate the utility of activities changes its direction. The age of eleven proves the turning point. It is only after this stage in their development that the testees are able to combine probability and value into one dimension, utility. Younger children ascribe the dominant role to one of the determinants and estimate the utility of their activities accordingly.Besides, the studies have permitted to determine that similarly to adults, children in their behaviour also follow the SEU criterion rather than the EU one.

Mechanicyzm i finalizm
Mechanism and Finality
view |
rights & permissions
| cited by
The author confronts mechanism with finality in respect of essence and form. Mechanism as a philosophical trend ought to be differenciated from classic mechanics originated by Newton. The latter is a deterministic theory employing mechanistic models (systems) and assuming that essential properties of a physical system such as position and momentum can be determined simultaneously and with required accuracy. The mechanistic determination is the exact determination of the consequent by the antecedent, and it permits to predict unmistakably the future evolution of a system as well as reconstruct its past behaviour.According to mechanists both animate and inanimate nature in their micro- as well as macro-physical structure obeyed mechanistic laws which themselves constituted a tool sufficient to solve any mysteries of the world. The mechanistic construction of the physical world was shaken first by quantum mechanics, and subsequently by rapidly developing biology. The problem of teleology has reappeared, particularly in biological sciences.Finality, often identified with teleology constitutes a complex and extremely controversial notion. It can denote either (1) characteristic features, especially of highly organized biological systems (structures), or (2) research and explication methods applied to biological phenomena, and finally (3) interpretations and theories of the reality.The confrontation suggests the following conclusions : (a) structures and changes occuring in living organisms are not completely réductible to mechanistic categories (notions) and explicable solely by means of their physical and chemical properties. Particular features of evolution of living systems such as direction of their activity, powers of adapting, plastic, self-regulating and other abilities demand new additional premises of explication; (b) at the formal level, the author following A. Grünbaum and N. Rescher has compared possibly different versions (varieties) of mechanism and finality. The advantage of such a confrontation and reduction of attitudes consists in considering the whole range (series) of mechanistic and teleological conceptions instead of a single causal and mechanistic point of view. It results in a more complete picture of interrelationships of mechanism and finality.

Sciama’s Vectorial Model of the Inertial Field

rights & permissions
| cited by
The article discusses briefly a vectorial model of the inertial field suggested by D. W. Sciama in 1953 („Monthly Notices of the Royal Astronomical Society” 113:1953 pp. 34-42). In constructing the model the author was inspired by the doctrine of Berkeley-Mach : inertia ought not to be measured in relation to absolute space, but in relation to masses filling the Universe. The model is of an approximate character. It is assumed that (1) the space is a Minkowski space, (2) the gravitational potential is a vectorial quantity (3) equations of the gravitational field formally assume a shape of Maxwell’s equations. On the analogy of electromagnetic induction one could speak within Sciama’s model of inducing inertia in a test particle by the remaining masses in the Universe. According to Sciama this proves the „machian” character of his model. One should notice, however, that in sourceless space Maxwell’s equations change into d’Alembert’s equations describing propagation of sourceless electromagnetic, or in Sciama’s version gravitoelectro- magnetic interactions. This constitutes the discrediting anti-machian property of the vectorial model of the inertial field. Development of ideas connected with the programme of realizing Mach’s principle, and springing from Sciama’s model is sketched at the end of the article. These are works of Lynden-Bell, Altshuler, Waylen, Gilman and Sciama himself.

O wartości informacji
On the Value of Information

The article discusses three conceptions referring to the pragmatic aspect of information. Their authors are E. Kofler, M. M. Bongard and A. A. Charkiewicz.Kofler’s proposal différenciâtes static, dynamic, particular and general values of information. It can be employed in the theory of planning and management.Bongard’s proposal permits to estimate the value of the given piece of information in relation to its recipient.Charkiewicz’s proposal can be employed to estimate the value of information in diverse cases where anxiety to attain certain actual goal is present. This may be e.g., a project involving a new vaccine, a criminal investigation, shooting at a moing target, a game of cards, etc.It has been shown that the above conceptions are embraced by the general system of teleological conceptions.Each of the presented conceptions permits the information value to receive arbitrary numbers, that is both positive and negative numbers, as well as number zero. Charkiewicz’s conception suggests a simple formula for calculating the information value. It is analogous to the formula for the quantity of information. It measures the value of information in units of the ammount of information.Charkiewicz’s conception has been discussed in a more detailed manner. The existing connections of the conception and the intuitive understanding of the information value have been shown together with the relations linking the theory of the information value with Hartley-Shannon’s theory of the ammount of information.The presented suggestions are valid for certain segments of the pragmatic aspect of information. The problem of constructing a complete theory of the information value, however, remains unsolved.

„Stwarzanie” materii a kosmologiczny model de Sittera
„Creation” of Matter and de Sitter World Model
view |
rights & permissions
| cited by
In all cosmological models matter is considered as something „given”. Density, pressure, quantity of barions, etc. are already present in the initial data. Only the steady-state cosmology, owing to the continual creation hypothesis, explains the origin of matter. As it is well known, however, the recent radioastronomical observations, strongly indicate against conclusions from the Bondi-Hoyle theory. In the present paper we are going to show another possible explanation of this strange fact that our world is not entirely empty. The proposed explanation (which has to be treated as a pure possibility only) holds within the frame of orthodox relativistic cosmology. The conservation laws are strongly satisfied.1. DE SITTER WORLD MODELDe Sitter world model (S-model) was of great importance during the early years of development of the relativistic cosmology. The space in this model is flat. The postulate of positive pressures and densities leads to the conclusion that S-world must be empty. In spite of this, the space of the model expands. The metric is stationary and invariant with respect to the displacement in time and simultaneously with respect to the change of the spatial scale. The S-model has no singularity, its temporal duration is unbounded. The S-world is empty and nothingness does not require a „birth” or a „death”.Because of its emptiness, the S-model does not describe our reality; it may be considered as the final state of the cosmic evolution. Indeed, one may show that in every monotonically expanding model, when t -> oo, density tendes to zero, and model asymptotically becomes de Sitterian.2. SINGULITARITY PROBLEMThe backward evolution of the monotonically expanding models leads to the singularity. Theorems of Hawking and others1 seem to indicate that singular, superdense states are inevitable in the cosmic history.Singularity problem may be treated in two different ways: (1) The superdense state of matter is literally the starting point of the cosmic evolution. The future theory (unknown till today) might show that the matter never existed „before” in states of lesser density. It is very probable that the concept of differentiable manifold is not applicable to the superdense states. In such a case the question „what was before?” would appear to be a senseless problem. (2) Before the expansion a contraction took place. Singularity appears when contraction changes into expansion. The following assumptions seem to be reasonable: (a) the same (as today) physical laws were valid during the contraction period; (b) the conrservation laws are satisfied with the respect to two different instants, both suitably distant from the singularity, before and after it.It will be convenient to assume: at the point of singularity t = 0, during the contraction t < 0, in the expansion period t > 0 (t being the cosmic time). In the next section only the possibility (2) will be considered.3. THE SYMMETRICAL WORLD MODELNow we are going to construct a world model accordingly to the following prescription: (i) Take any monotonically expanding model with the initial singularity (model M). When t→∞, the M-model changes into de Sitterian world (S). (ii) Reverse the direction of time in the composed model M->S. Denote the model M with the reverse time arrow by — M, and the model S in the negative time by — S. (iii) Having now two symmetrical models: (1) — M→— S and (2) M→S, piece them together at the singular point (this is not a „smooth joining", in any way). In order to make this possible we must assume (quite separate physical assumption) the symmetry of time with respect to the singular instant.As the result we get the following picture of cosmic history: beginning from the de Sitterian empty state matter gradually appears, i.e. its density increases from emptiness until it reaches infinity at the singular instant, then contraction changes into expansion, density decreases, matter seems gradually to vanish and world becomes de Sitterian again.Having in mind that the contraction in positive time is equal to the expansion in negative time the foregoing picture may be described as following: time is passing in the reversal direction (with respect to its present arrow), universe expands from the de Sitter empty state at the sinqular point time changes its direction, expansion continues up to the de Sitter final state.At the confines of our model the matter asymptotically emerges from the de Sitterian emptiness and asymptotically vanishes in de Sitter empty state again. The following terminology seems to be appropriate: at the extremities of our symmetrical model the matter being respectively „asymptotically created” („the birth of the universe”) and „asymptotically annihilated” („its death”). But we must remember that it is density, not matter, which is asymptotically created resp. annihilated.In the superdense states of matter time must not be homogeneous and therefore the energy conservation law must not hold, but owing to the assumption (2b) (see section 2) the conservation laws (including conservation of energy) are valid during the whole process of cosmic evolution (except perhaps in the vicinity of the singular instant). Especially when matter is asymptotically created and asymptotically annihilated the conservation laws are strongly satisfied.Our symmetrical world is not entirely a Machian model, in which all properties (including the presence of matter) would induce themselves mutually. De Sitterian boundary conditions at both infinities appear to be its absolute, anti- -machian properties.

Principles of Division of Scientific Terms

rights & permissions
| cited by
The article concerns the analysis of some principles governing the division of scientific terms, such as (1) observability (2) conjecture, (3) precision, (4) degree of abstractness, (5) conceptual organization, (6) dependence of the terms upon the theory. The first four criteria (1-4) are put forward by the representatives of logical empiricism while the other two (5-6) are suggested by the exponents of the historical philosophy of science. The article aims at proving that particular principles generate several divisions rather than a single one and according to the employed criterion a given terms either an observational notion or one depending on the theory, or a unobservational notion or one independent of the theory.

Doświadczenie naukowe jako baza wyjściowa w rozważaniach filozoficznych
L’éxpérience scientifique comme point de départ des recherches philosophiques

La première partie de cet exposé sert à démontrer, que la philosophie peut s’appuyer sur l’expérience scientifique et non seulement sur l’expérience quotidienne. Les résultats des sciences expérimentales peuvent servir de base matérielle aux recherches philosophiques.Dans la seconde partie on adopte les raisonnements réductifs et la méthode des diverses abstractions. Comme matérielle peut servir p.ex. la théorie de l’expansion du monde. La première abstraction physique — c’est l’umivers borné dans le temps, comme l’ensemble des êtres. Nous passons à la considération de la structure antique de l’être. L’être borné dans le temps peut exister ou non exister, donc il est contingent. Cela peut être appliqué à l’univers entier. Donc l’existence de ce monde pourrait s’expliquer par l’existence d’un Etre Premier — Créateur du monde. De cette manière on peut compléter les raisonnements de E. Whittaker.Dans la troisième partie on accomplit une analyse réflexive des analogies dans le monde, des lois physiques et des degrés des êtres. Cela conduit à l’acceptation de la Sagesse Divine qui créa le monde des êtres matériels.Une dissertation nous amène à trouver un type du composé hylemorphique. Comme matière première on adopta les champs des forces. La forme par contre sera liée avec les particules caractéristiques du champ: ainsi avec le champ électromagnétique seront liés les photons, avec le champ nucléaire — les mésons, etc.L’action du Créateur pourrait avoir lieu sur la matière première c’est-à-dire de l’intérieur des êtres.

R. Carnapa ujęcie wzajemnej relacji terminów teoretycznych i obserwacyjnych
R. Carnap’s Conception of Interrelation of Theoretical and Observational Terms
view |
rights & permissions
| cited by
The article deals with methodologically important problems connected with distinguishing theoretical and observational terms in the language of the theory ofnatural sciences.Part one discusses the problems as formulated by R. Carnap. His conception is connected with the principles of philosophy of logical empiricism. Different definitions of both kinds of terms given by this author are presented. Particular attention is paid to different understanding of the interrelation of the terms — from the position of the so-called logical constructionism, through reduction sentences, to the conception of theoretical terms being given empirical interpretation by the so-called C-postulates.Part two contains critical remarks. Above all it is pointed out that the so-called empirical basis, counter to empiricist’s opinion, is not irrefutable. Carnap’s thesis that the division of terms into theoretical and observational is clear- -cut has been contested as well. A new definition of the observational term different from that of Carnap’s has been attempted together with a different principle of terms, [being made] relative to a particular theory. Also, a more detailed analysis proves that in scientific practice the C-postulates are accepted and employed in a different manner than it was assumed by Carnap.

Stratygraficzna pozycja fauny archeocjatowej z Łysej Góry
Stratigraphic Position of Archaeocyathid Fauna from Łysa Göra (The Holy Cross Mountain)

Stratigraphy of the Łysa Góra anticline (the Holy Cross Mountain, Central Poland) is controversial. Lithologically it is defined as middle and upper Cambrian. The abundant archaeocyathid fauna discovered by the author in 1968-1973 at Łysa Góra, in the strata cropping out at the stretch of ca. 300 metres (fig. 1) sheds new light upon the stratigraphy of this region. The tectonic situation of Łysa Góra permits to infer that the orthoquartzite strata with the fauna were upthrust from an older Cambrian bedrock. The strata are situated between the Cambrian break- -thrust upon Devonian from the south (the Holy Cross dislocation — J. Czarnocki) and the offsetting the upper Cambrian strata with an amplitude of ca. 1,500 metres to the north (H. Tomczyk), as well as two lateral berms (fig. 2). A lower Cambrian cropping out is not out of question. Among the collected material one may probably differenciate Archaeocyathellus sp. (fig. 5, 6, 8, 9, 10, 12, 13) and forms belonging to the class Anthocyatha Okulitch 1943 (Anthomorpha sp.?) (fig. 7, 11, 14). Detailed systematic classification is being worked out.
