By considering the irreducible representations of the Lorentz group, an analysis of the different spin-2 waves is presented. In particular, the question of the helicity is discussed. It is concluded that, although from the point of view of representation theory there are no compelling reasons to choose between spin-2 waves with helicity σ=±1 or σ=±2, consistency arguments of the ensuing field theories favor waves with helicity σ=±1.

al-juzʼ 1. al-Mushkilāt al-falsafīyah -- al-juzʼ 2. Taṭawwur manāhij al-ʻulūm.

Critical study on with special reference to peripatetics, Avicenna, 980-1037.

Anecdotes from early Islamic history; includes moral of these stories reflecting on Islamic religious life and Islamic ethics.

This book does not demand continuous reading; but at whatever place one opens it, one will find matter for reflection. The most useful books are those of which readers themselves compose half; they extend the thoughts of which the germ is presented to them; they correct what seems defective to them, and they fortify by their reflections what seems to them weak. It is only really by enlightened people that this book can be read; the ordinary man is not made (...) for such knowledge; philosophy will never be his lot. Those who say that there are truths which must be hidden from the people, need not be alarmed; the people do not read; they work six days of the week, and on the seventh go to the inn. In a word, philosophical works are made only for philosophers, and every honest man must try to be a philosopher, without pluming himself on being one. This alphabet is extracted from the most estimable works which are not commonly within the reach of the many; and if the author does not always mention the sources of his information, as being well enough known to the learned, he must not be suspected of wishing to take the credit for other people's work, because he himself preserves anonymity。.

Study on Islamic religious life and Islamic ethics in view of various astonishing Islamic stories.

Purpose of the study is to shed light on the role of psychophysiology in the creative process, namely, the style corrections connected with pathological changes in the artist’s organism, deviating from empirical-descriptive methods. Theoretical basis of the study implies the interpretation of the notions style and disease not in their narrow professional limitation but from the standpoint of expanding the parameters of these concepts to philosophical dimensions. Based on the principle of analogy, the research findings prove that non-mimetic creative process (...) manifests itself exclusively in connection with a human from a bodily viewpoint through anthropological mimesis, which can program the propensity to certain capabilities of the individual organism. C. G. Jung was the first who pointed to the productivity of this method in his work "Theoretical Reflections on the Nature of the Psyche". The creativity phenomenon reflects not only "pure" psychology and the intellectual and spiritual component but also its relation to the artist as a physical being. It, outside its belonging to and being conditioned by transcendent factors, includes a quantitative aspect related to the moment of intensity. The disease acts to some extent as a stimulator of the production/change of aesthetic enzyme. In this context, the dialectic method is also effective because the subject of study cannot be comprehensively argued using naturalistic approaches only and requires a semantic explanation too. The essence of it is the logic of contradictions. In this case, the antinomy of matter-spirit plays a conceptual role in the projection on the plane of word-formation. Originality of the research findings is in the expansion of the causal relationship range of the creative process, namely the inclusion of the factor of psycho-physiological pathology into the system artist-work. This factor performs important stylistic functions. Conclusions. In contrast to scientific studies, where 1) style is analyzed separately and 2) the figure of the artist, this study argues the need to correlate these issues, taking them beyond descriptiveness to avoid schematics and one-dimensionality.
