We show that the variety of n -dimensional weakly higher order cylindric algebras, introduced in Németi [9], [8], is finitely axiomatizable when n > 2. Our result implies that in certain non-well-founded set theories the finitization problem of algebraic logic admits a positive solution; and it shows that this variety is a good candidate for being the cylindric algebra theoretic counterpart of Tarski’s quasi-projective relation algebras.

The concept of truth is a fundamental category in the theory of knowledge and philosophy in general. Other philosophical categories presuppose the concept of truth as their content or as the goal of investigatory inquiry. Philosophy begins historically with rejection of any form of opinion in the name of truth and with the counterposing of what truly exists to the variety of appearance. Thus was born theoretical thought, for which in antiquity philosophy was a synonym.

SummaryIf you know you can recognise positive instances of a property, can you use this knowledge so as to be able to recognise also its negative instances? This is the question to be adressed.

Spatial evolutionary game theory explains how cooperative traits can survive the intense competition in biological systems. If the spatial distribution allows cooperators to interact with each other frequently, the benefits of cooperation will outweigh the losses due to exploitation by selfish organisms. However, for a cooperative behavior to get established in a system, it needs to be found initially in a sufficiently large cluster to allow a high frequency of intracooperator interactions. Since mutations are rare events, this poses the question (...) of how cooperation can arise in a biological system in the first place. We present a simple model which captures two concepts from genetics that can explain how evolution overcomes the emergence problem. The first concept is, often in nature, a gene may not express its phenotype except under specific environmental conditions, rendering it to be a “silent” gene. The second key idea is that a neutral gene, one that does not harm or improve an organism’s survival chances, can still spread through a population if it is physically near to another gene that is positively selected. Through these two ideas, our model offers a possible solution to the fundamental problem of emergence of cooperation in biological systems. (shrink)

In current philosophical literature we encounter many contradictions, in particular, numerous difficulties and conflicts concerned with differentiation between the logical and ontological approaches to defining the category of matter; with an adequate interpretation of the categories of essence, substance, structure, and quality; with certain problems in the dialectics of practice and theory; and so forth. In this article, I shall consider the problem of being and structure. A correct understanding of this problem presumes, above all, a fundamental distinction between the (...) basic questions of epistemology, i.e., the question of the independence of being from consciousness, and the ontological characteristics of being.

It is a huge pleasure to engage with Prof. Shaw’s careful and close reading of my article. Though almost a decade old, many of the issues are becoming only more relevant as it seems that Roe v Wade will be overruled in the U.S. and travel for abortion will become a sad reality.1 I appreciate how deeply Prof. Shaw interacts with my article and am full of praise for his work, but given the small space allocated here I only focus (...) on our few places of disagreement.

Many methods are conceivable for resolution of the difficulties arising when motion is depicted in the logic of concepts. We shall set forth some of these methods, presenting them within the framework of the discussion in which V. I. Sviderskii, B. A. Dragun, and I. S. Narskii have already participated. In our opinion, attention must be directed primarily to the fact that in resolving the contradictions in the presentation of motion by means of ideal mathematical abstractions, it is impossible to (...) base ourselves directly upon that which is occurring in the sphere of the things which we perceive with our senses. It is particularly when one forgets this fact that contradictory situations usually result. However, this does not at all mean that these data are of little value in treating of motion. Furthermore, the refinement of the meaning of the concepts in terms of which motion is described, taken together with the requirement that there be a rigorous differentiation between theories based on ideal abstractions and theories based on concepts derived from the sphere of empirical existence, may lead to the resolution of Zeno's paradoxes.

My discussion in previous chapters was limited to the origin of Chinese culture and its fundamental spirit exhibited in the process of historical development. In what follows, I am going to discuss the spirit of Chinese culture in specific areas such as philosophy of nature, theory of human nature, ideals of moral life, the world of daily living, the world of ideal personalities, and the spirit of art and religion. The center of discussion will be a comparison between Chinese and (...) Western philosophy and culture. Therefore, before discussing Chinese cosmologies, I am going to present the cosmologies in the West as a preparation for comparison. Nevertheless, the main task of this chapter is not a special treatise on the natural sciences and philosophies of China and the West. Instead, my focus is on the differences between ideas of nature, their values and fundamental spirit. I hope my readers understand this point first. (shrink)

The theme "Dostoevsky and Nietzsche" is one of the most important for understanding the meaning of the abrupt changes that took place in European philosophy and culture at the turn of the nineteenth century. This epoch is still a puzzle: it was a flourishing period for the creative powers of European humanity and at the same time the beginning of the tragic "breakdown" of history that gave birth to two world wars and unprecedented calamities, the consequences of which Europe has (...) been unable to overcome, as shown by the uninterrupted decline of traditional culture, which began at the end of World War II and still continues today. In this epoch, as in the eighteenth century, which culminated in the Great French Revolution, philosophy came out of the study onto the street and became a practical force that steadily undermines the existing order of things; in a certain sense it was precisely philosophy that called forth the catastrophic events of the first half of the twentieth century, which had as never before a metaphysical subtext. At the center of the upheaval that engulfed absolutely all forms of European civilization and culminated, at the beginning of the twentieth century, with the rise of nonclassical science, "nonclassical" art, and "nonclassical" philosophy, was the problem of man, his essence, the meaning of his existence, and the problem of man's relations with society, the world, and the Absolute. It is no coincidence that M. Scheler used the term "anthropological turn" to describe the changes that occurred in philosophy in this epoch; what had long been implicit in philosophy and art and in paradoxical fashion had become apparent even in the new scientific theories, was now made clear: man is not a tiny "atom" in boundless and alien being, but the starting point for all suppositions, the primary field of meanings from which any philosophical or scientific "questioning" must depart.

Philosophical study of the Sufis aspect of Islamic spiritual life.

If there is an inherent connection between love and generosity, between love and creativeness, as this book argues there is, then how can love itself be selfish, destructive and tyrannical? Concerned with questions about love in its different forms, this book seeks and discusses the views of writers--Plato, Proust, Sartre, Freud, D. H. Lawrence, Erich Fromm, C. S. Lewis, Kierkegaard, Simone Weil and Kahlil Gibran--who have suggested distinctive solutions to the problems which love poses in the face of its obstacles. (...) The enquiry which the book undertakes emcompasses both the conceptual and existential experience of love. (shrink)

Whereas previous studies have criticized low-quality products for inadequate safety, this paper considers only safe products, and it examines the ethics of designing and selling low-quality products. Product quality is defined as suitability to a general purpose. The duty that companies owe to consumers is summarized in the Consumer-Oriented Process principle: “to place an increase in the consumer’s quality of life as the primary goal for producing products.” This principle is applied in analyzing the primary ethical justifications for low-quality products: (...) availability and applicability. Finally, a low-quality product should be designed afresh, not by altering an existing high-quality product. (shrink)

The history of human culture records diverse notions about possible forms of existence of the soul or analogous substances after the disintegration of the corporeal shell. Even where investigators of primitive cultures conclude that some community is at such a low level of development that it has elaborated no ideas concerning the existence of gods, demons, spirits, and so forth—even there, a cautious attitude toward such evidence is necessary. Actually, the conviction that "savages" do not have such beliefs may be (...) less a reflection of the real state of affairs than, let us say, the reluctance of members of that community to familiarize Europeans with elements of their culture that bear on spheres of life activity that are most meaningful for the tribe. Thus the anthropologist W.R. Trevathan mentions particular difficulties arising from attempts to study the actions and rituals associated with the birth of a child . Even where there is a friendly attitude toward the investigator, there still remain spheres of life to which representatives of the tribe were reluctant to allow Europeans access. For example, there is the well-known case where one anthropologist, who had lost hope of "officially" learning about the character of the rituals accompanying the birth of an infant, attempted to sneak a look at what was happening in the hut. This curiosity almost cost him his life, despite the recent goodwill of his host. (shrink)

Marcel Proust’s works contain a lot of ideas consonant with the ideas that were actively discussed by philosophers of his time. Many philosophers focused on the issues of perception, memory, will, freedom, personal identity, etc., which constituted an important part of academic curriculum. Proust familiarized himself with the issues studying philosophy at the Lyceum (he was taught by Alphonse Darlu) and at the Sorbonne. In his novel In Search of Lost Time, Proust describes an existential experience of his character viewing (...) these issues from a particular perspective, through the prism of the main character’s lifelong search of his calling. He gradually proceeds from philosophical psychology exploring the interaction of memories and impressions in a particular perception, to philosophy proper, to metaphysics aimed at understanding the truth, at going beyond time. The article traces some moments of this transition, shows that for Proust it is not just the work of memory that is important but the emphasis on those states of consciousness where the present and the past coincide, merge, and thereby we go beyond time, to eternity. The author analyzes some images and signs that accompanied the character of the novel on the way to the realization of his calling. Particular attention is paid to the Proustian interpretation of the role of art in changing and enriching the perception of the world, as well as the importance in human life of a habit in which positive and negative aspects are highlighted. Proust himself believed that a work of art is an optical instrument through which the readers begin to discern in themselves what they would otherwise fail to see. His own novel was such an instrument. (shrink)

Human spirituality is originally tied to the material means of its expression, often verbal. No wonder the word is called the universal cover of all forms of human consciousness.
