. We prove a jump inversion theorem for the enumeration jump and a minimal pair type theorem for the enumeration reducibilty. As an application some results of Selman, Case and Ash are obtained.

In the paper we introduce and study regular enumerations for arbitrary recursive ordinals. Several applications of the technique are presented.

The jump operator on the ω-enumeration degrees was introduced in [I.N. Soskov, The ω-enumeration degrees, J. Logic Computat. 17 1193–1214]. In the present paper we prove a jump inversion theorem which allows us to show that the enumeration degrees are first order definable in the structure of the ω-enumeration degrees augmented by the jump operator. Further on we show that the groups of the automorphisms of and of the enumeration degrees are isomorphic. In the second part of the paper (...) we study the jumps of the ω-enumeration degrees below . We define the ideal of the almost zero degrees and obtain a natural characterization of the class H of the ω-enumeration degrees below which are high n for some n and of the class L of the ω-enumeration degrees below which are low n for some n.

Concordance of the poetic works of Giorgos Seferis which presents all the principal “words” of the texts in an alphabetical list, stating how often each word occurs, giving a precise location and a relevant piece of text for each occurrence. We found ca. 9500 different Greek words in 39000 different occurrences, so our concordance has 50.000 lines of text. The technical procedure required four main steps: text entry and tagging, production of the concordance, correction of the contexts, formatting for print.

Socrates' account of recollection in the Phaedo has been the subject of much study, but little attention has been paid to the questions whether and how far his arguments address Simmias' claim that he needs to recollect and be reminded that learning is recollection . I shall argue that Socrates reminds Simmias by appealing to Simmias' experience of question-and-answer discussion in order to show him how in these discussions they are regaining forgotten knowledge, but have not yet completed this process.

The article traces the lines of interrelation of philosophy as a systematic knowledge of the world and literature as a form of artistic contemplation. Conceptual and figurative comprehension of the world, according to the author, are attributive properties of the spiritual life of society. In the paradigm of this understanding, the union of philosophy with diverse types of literary creativity is considered as a basic component of the national spiritual culture of the XIX — early XX century, which determined its (...) national peculiarity, becoming a kind of symbolic code. On the one hand, she set the main vector of literary creativity, including the search for the meanings of being, and filled the intuitions of artistic and imaginative thinking with philosophical content, on the other hand, she "added" metaphysics of philosophical thought with ideological questions about progress, social justice and equality, insuring philosophical reflection from the dictates of rigid conceptual schemes.

The development of science and engineering, and the social transformations occurring in the world of today open entirely new prospects to humanity. The scale and consequences of decisions made are expanding as never before in any previous period of history, and people's responsibility is also increasing. Herein lies one of the reasons for the constantly increasing attention to human freedom and to the intimately related problems of choice and decision-making.

The article describes the tendency of integration of pedagogical concepts of education on a philosophical basis. The philosophical approach involves a certain method of studying education — "philosophizing", which is directly related to the study of a person, his life, his personality, the search for means that help him in self-determination, finding the meaning of life.
