Making the Quantum of Relevance

Summary  The two Heisenberg Uncertainties (UR) entail an incompatibility between the two pairs of conjugated variables E, t and p, q. But incompatibility comes in two kinds, exclusive of one another. There is incompatibility defineable as: (p → − q) & (q→ − p) or defineable as [(p →− q) & (q →− p)] ↔ r. The former kind is unconditional, the latter conditional. The former, in accordance, is fact independent, and thus a matter of logic, the latter fact dependent, and thus a matter of fact. The two types are therefore diametrically opposed.In spite of this, however, the existing derivations of the Uncertainties are shown here to entail both types of incompatibility simultaneously. Δ E Δ t ≥ h is known to derive from the quantum relation E = hν plus the Fourier relation Δ ν Δ t ≥ 1. And the Fourier relation assigns a logical incompatibility between Δ ν = 0, Δ t = 0. (Defining a repetitive phenomenon at an instant t → 0 is a self contradictory notion.) An incompatibility, therefore, which is fact independent and unconditional. How can one reconcile this with the fact that Δ EΔ t exists if and only if h > 0, which latter supposition is a factual truth, entailing that a Δ E = 0, Δ t = 0 incompatibility should itself be fact dependent? Are we to say that E and t are unconditionally incompatible (via Δ ν Δ t ≥ 1) on condition that E = hν is at all true? Hence, as presently standing, the UR express a self-contradicting type of incompatibility.To circumvent this undesirable result, I reinterpret E = hν as relating the energy with a period. Though only one such period. And not with frequency literally. (It is false that E = ν . It is true that E = ν times the quantum.) In this way, the literal concept of frequency does not enter as before, rendering Δ ν Δ t ≥ 1 inapplicable. So the above noted contradiction disappears. Nevertheless, the Uncertainties are derived. If energy is only to be defined over a period, momentum only over a distance (formerly a wavelength) resulting during such period, thus yielding quantized action of dimensions Et = pq, then energies will become indefinite at instants, momenta indefinite at points, leading, as demanded, to (symmetric!) Δ E Δ t = Δ p Δ q ≥ h’s.     

Instantiae: An introduction to a twelfth century technique of argumentation

An instantia is a technique to refute other's arguments, found in many tracts from the latter half of the twelfth century. An instantia has (or appears to have) the same form as the argument to be refuted and its falsity is more evident than that of the argument.Precursors of instantiae are among the teachings of masters active in the first half of the century. These masters produce counter-arguments against various inferential forms in order to examine their validity. But the aim of producing counter-arguments change in the latter half of the century into refuting other's arguments to win in debate by any means available. Logicians of that period do not care whether the counter-arguments (instantiae) are sophistical or not, viz. the falsity of instantiae is or is not due to the flaw common to the argument to be refuted.Many instantiae they produce involve logical entanglements into which they themselves have little clear insight. Some instantiae and the attempts to explain them grows into the new theories in the terminist texts around 1200 A.D., when instantia literature itself disappears. Some instantiae and the issues they raise have no place in terminist texts, and sink into oblivion.Abbreviations CIMAGL Cashiers de l'Institut du Moyen-Âge grec et latin, Copenhagen 1969. - I. Mon.

The Latin American contribution to the psychoanalytic concept of phantasy

The author argues that the ubiquity of phantasies at various levels of mental functioning is undisputed in the current schools of psychoanalytic thought; however, she demonstrates some variations in their understanding of how the psychotherapeutic access to different configurations occurs. In the process of examining and acknowledging the central role played by unconscious phantasies in his patients’ symptoms, Freud gradually broadened the vernacular meaning of the German word ‘Phantasie’ that refers to imagination and the world of imagination, conferring on it the specific features that came to characterize its use in the psychoanalytic vocabulary. Later, the expansion of the concept derived from Melanie Klein’s clinical material obtained from child analyses gave rise to important debates. The author discusses the main points of disagreement that led to these debates, as well as their various theoretical and technical implications. Psychoanalytic associations in Latin America were strongly influenced by Klein and her followers. Thus, most of their scientific writings use the concept of unconscious phantasy put forward by the Kleinian school. Taking Kleinian principles as their starting point, Baranger and Baranger made the most original Latin American contribution to the concept of unconscious phantasy with their works on the unconscious phantasies generated by the analytic pair.     

Reasoning Ability in Young Children

The astrological assumption of personality differences among individuals born under different sun signs was investigated. Significant differences were obtained between sun sign groups on four of the 18 scales of the California Psychological Inventory (CPI) as follows: Communality, Socialization, Flexibility, and Femininity. The overall pattern of results based on F ratios, multiple comparisons between means, and estimates of strength of association was interpreted as showing no meaningful relationships between sun sign and scores on Communality, Socialization, and Flexibility. Adopting even the most conservative standards of inference, however, all of the test statistics employed indicated a powerful effect on the Femininity scale. Implications for future research were discussed.     

Suszko’s Thesis,Inferential Many-valuedness,and the Notion of a Logical System

According to Suszko’s Thesis, there are but two logical values, true and false. In this paper, R. Suszko’s, G. Malinowski’s, and M. Tsuji’s analyses of logical twovaluedness are critically discussed. Another analysis is presented, which favors a notion of a logical system as encompassing possibly more than one consequence relation.

PHYSICAL SCALE EFFECTS AND PHILOSOPHICAL THOUGHT EXPERIMENTS

Abstract: The scales across which physical properties exist are vast and subtle in their effects on particular systems placed locally on such scales. For example, human experiential access is restricted only to partial segments of the mass density, size, and temperature scales of the universe. I argue that philosophers must learn to appreciate better the effects of physical scales. Specifically, thought experiments in philosophy should be more sensitive to physical scale effects, because the conclusion of a thought experiment may be undermined by unintentionally ignored scale effects, and the changes required to obtain the foreground state of affairs in a thought experiment might require unacknowledged scale‐spanning changes to the contextual background. I discuss four philosophical thought experiments: Putnam's Twin Earth and Brain in a Vat, Searle's Chinese Room, and Chalmers's Zombies Without Qualia. I close by briefly defending the greater interest and importance of physical possibility over logical possibility.     

BEYOND BARBOUR OR BACK TO BASICS? THE FUTURE OF SCIENCE‐AND‐RELIGION AND THE QUEST FOR UNITY

Reflecting on the future of the field of science‐and‐religion, I focus on three aspects. First, I describe the history of the religion‐and‐science dialogue and argue that the emergence of the field was largely contingent on social‐cultural factors in Western theology, especially in the United States. Next, I focus on the enormous influence of science on Western society and on what I call cultural scientism, which influences discussions in science‐and‐religion, especially how theological notions are taken up. I illustrate by sketching the way divine action has been studied in science‐and‐religion. The divine‐action debates may seem irrelevant to theologians because the way divine action is dealt with in science‐and‐religion is theologically problematic. Finally, I analyze the quest for integration and unity of science and religion that underlies much of the contemporary field of science‐and‐religion and was stimulated particularly by the efforts of Ian Barbour. I argue that his quest echoes the logical positivist vision of unification and has a strong bias toward science as the sole source of rationality, which does not take theology fully seriously.
