Learned men have been writing about happiness since antiquity: from Greek times, there is Aristotle's treatise, included in the Nicomachean Ethics; from Roman, Seneca's De Vita Beata. Later came the Christian writings on this subject, especially another De Beata Vita, written by St. Augustine. The point of view is different from Aristotle's or Seneca's but the subject remains the same. In the Middle Ages also treatises on happiness were produced, and these eventually became part of the 'summae'. St. Thomas devoted (...) q. 2-5 of the Prima Secundae to happiness and q. 3 1-39 bear on it indirectly. In more modern times works on happiness continued to be written. Some authors carried on the Christian tradition which maintained that happi­ness is only attainable in the next world; to these belong the earliest works written in Polish. Other treatises - especially those of the Age of Reason - hold the opposite concept, that the only happiness man can expect is to be found on earth. In the 18th century there were so many of these treatises that it was possible to produce a whole anthology: The Temple of Happiness, or as it was originally called Le Temple du bonheur, ou recueuil des plus excellents traites sur Ie bonheur (2nd ed. , 1770).

A fully quantum-mechanical description of the spontaneous emission from an excited two-level atom placed in front of a two-slit interferometer is given. Global modes of the electromagnetic field in a two slit system are derived within the Kirchhoff-Huygens diffraction approximation, serving as a base for the field quantization. The standard Fermi's golden rule, supplemented by a factor coming from the nontrivial mode structure caused by the presence of the two-slit interferometer, is used to show that interference results from the position-dependent (...) coupling between the atom and different field modes of the system.

Problems connected with the questions of: being-nonbeing, existence, modes of existence and alike, belong to the basic and most important in metaphysics. The article discusses some answers to the aforementioned issues, as proposed by the ancient philosophers, St Thomas Aquinas, R. Ingarden and A.N. Whitehead. In the Appendix some remarks are made on Aristotle’s and S. Thomas’ theory of act and potency.

In this article, on the basis of questionnaire data collected for other purposes, the Authors want to show the consequences of various methods of shortening of tests and what may result from such an action for diagnosticians, researchers and examined individuals. The research aim of the work is to show the best method of shortening of the scale of questionnaires. Will shortening of a questionnaire according to different statistical techniques bring the same results? Will the quality of shortened scales be (...) comparable? Is any of statistical techniques better for shortening of the scale of a questionnaire? The obtained results suggest a poorly controlable effect of the methods of questionnaire shortening. Moreover creating a short version on the basis of the results collected with the use of the full version leads to obtaining a tool with unknown diagnostic and psychometric properties. (shrink)

The paper attempts to show that Christian hope is not a product of religious fantasy. It finds today an ally in the dialogue with the natural sciences which started in recent years on the topic of the ultimate destiny of the world. The natural sciences have confirmed that the universe is doomed to physical annihilation. Humanity with its cultural riches, scientists say, is only an episode in universal history and doomed to perish. Hence, if the Earth is nothing more than (...) an island of rationality in a cosmic void, then the only thing we can do is to keep up a heroic attitude worthy of human beings towards our own fragile existence. Contemporary science’s visions of the future are pessimistic: abundant, though short-lived, evolution culminating in a sense of final futility and the ultimate destruction of all life in the universe. Such forecasts question religion’s claims for the eschatological transformation of all creation. Christian eschatology does not accept, however, reductionist presuppositions about the very nature of reality. The universe contains levels of meaning far richer than what we have been able to discover sofar. Theology’s task is not to provide easy consolation, or generate false hopes. It has a good reason to avoid catastrophism, and maintain calm in its strivings to keep up our faith in God’s concern for the destiny of all His creatures. Theologians have to take a serious stand on the very concept of finitude, furthered by natural and social sciences. This, in turn, will require critical review of such concepts as the world’s future in God, hope and new creation. This effort must be undertaken in dialogue with the scientific views of the world’s finitude. Both sides are prone to stereotype judgements and shallow answers which must be corrected in consideration of the complexity of the issue at hand. Christian theology has to justify its claim to truth, but certainly not by launching battles with science. Christian hope shows the new creation not as annihilation and destruction of the old but as its ultimate transfiguration and salvific transformation. It speaks about the paradox of continuity/discontinuity in this new universe’s emergence. Special attention is paid in the paper to the “logical” structure of matter. If the world ofultimate events is, in fact, to be a new world of the resurrection, created by transition into new reality, then certain scientific suggestions and data on the present world’s processes could prove helpful in grasping the truly cosmic dimensions of Christian hope. Crucial here will not so much be particular data but rather a sort of meta-science allowing the deduction of general concepts from the detailed achievements of scientific research. Such generalized insights include today the following elements: 1) the dynamic concept of physical reality, 2) the relationality of its processes and, 3) a deeper understanding of the complexity of matter/energy as carriers of a specific information-bearing pattern. It appears that there are some similarities in science’s and theology’s strivings for a deeper understanding of the truth of reality, which continues to evade our theories and teaches us modesty. Neither method nor concept has yet managed to explaineverything. There exists no universal key to a comprehensive interpretation. The postulate to avoid reductionism in approaching the manifold richness of reality is addressed to scientists and theologians alike. (shrink)
