Speech and music signals are multifractal phenomena. The time displacement profile of speech and music signal show strikingly different scaling behaviour. However, a full complexity analysis of their frequency and amplitude has not been made so far. We propose a novel complex network based approach (Visibility Graph) to study the scaling behaviour of frequency wise amplitude variation of speech and music signals over time and then extract their PSVG (Power of Scale freeness of Visibility Graph). From this analysis it emerges that the scaling behaviour of amplitude-profile of music varies a lot from frequency to frequency whereas it’s almost consistent for the speech signal. Our left auditory cortical areas are proposed to be neurocognitively specialised in speech perception and right ones in music. Hence we can conclude that human brain might have adapted to the distinctly different scaling behaviour of speech and music signals and developed different decoding mechanisms, as if following the so called Fractal Darwinism. Using this method, we can capture all non-stationary aspects of the acoustic properties of the source signal to the deepest level, which has huge neurocognitive significance. Further, we propose a novel non-invasive application to detect neurological illness (here autism spectrum disorder, ASD), using the quantitative parameters deduced from the variation of scaling behaviour for speech and music.

The article attempts to prove that Darwinism in popular culture plays a role of a theory of everything. Bestselling authors of popular science such as Edward O. Wilson, Richard Dawkins and Bill Bryson have acquainted general public with the theory of evolution, and its newest facet — the Modern Synthesis. Darwinian paradigms, as defined by Thomas Kuhn, are also used in popular books on cosmology, sociobiology, psychology, and religious studies. Moreover, the Darwinian grand narrative of evolutional history shapes the way in which contemporary mass culture presents the history of our planet in numerous educational TV series. Last but not least, Charles Darwin himself has recently become a popular icon and the story of his life is remade in a growing number of fiction and non-fiction books and movies.

The article presents an analysis of the concept of the art instinct. This is a notion introduced by Denis Dutton in his concept of the evolution of art. The autor analyses the internal coherency of Dutton’s concept and its implications, with investigations in the context of evolutionary biology and biological anthropogenesis. The article’s conclusions are that: (1) the idea of art instinct is incoherent and difficult to uphold in the light of contemporary knowledge of the mechanisms of evolution and the course of anthropogenesis; (2) it is, however, a notion that is convenient and explanatorily efficient, as long as one accepts—among other things—the reservation about the non-teleological course of evolution; (3) the art instinct and the phenomenon of art cannot be explained without referring to social processes.

In these remarks I do undertake one more time the attempt to answer the following question: what do agnostics really want? This issue is so complicated that even the agnostics themselves had great trouble in delivering the answer. This is also related to these agnostics, such as the recalled here Charles Darwin, Albert Einstein, and Stephen W. Hawking, who belong to the greatest format of scholars. The agnostics are being distanced from, both the atheists and theists. However they do judge differently their views it is important that as well the first as the latter ones may appreciate what stands behind agnosticism and this might be very variable.

The article The Influence of the Bible on Civilization (The Bible and Natural Sciences) shows us the importance of the Holy Bible in relation to the forming of Western civilization. The Bible is at the foundation of the heritage of European civilization. Written down during the period of almost 1500 years, it contains truths that concern all fields of life, both on the individual and the social level. As a work of literature it had its role, together with the civilization of Ancient Greece, in the origins of sciences. Science and religion are two very important elements of human culture. All reflections on the subject of the genesis of the world have their roots in these two basic aspects of seeing reality. Everything that exists needs an explanation of its origin. Thus the basic question that gave the beginning to philosophy was the question of the human being about himself and about the Universe. The relation of the science of creation, originating from the biblical description showing God as giving existence to everything, came into conflict with the empirical description of the beginning of the Universe and man in it. The questions that Latin civilization took from Greek philosophy and Christianity, based on biblical foundations, were transformed during the course of history to a conflict between science and faith, which began with the Copernican revolution and the Galileo issue. It had its greatest inflammation in the 19th century, as the result of the discoveries in the field of bio- logy, mainly connected with the theory of evolution of C. Darwin. One of the basic aspects of this conflict is the question of the origin of the world, which issue is, so to say, a natural place of meeting of theology with natural sciences. This conflict began as a result of trying to discover the essence of God's message contained in the Bible, by natural sciences. This discovering was an interpretation of the inspired text in relation to the eternal truth and to cultural variables, and also to civilization frames.

Warsaw highbrow journal Biblioteka Warszawska in the second phase of its history, 1864–1914. It was a period of rapid development of the natural sciences, accelerated by the gradual reception of Darwin's theory of evolution. The arrival of Darwinian naturalism had major consequences beyond the scientific community. Although it led to the abandonment of Romantic evolutionary ideas, it not only reaffirmed the Eurocentrism of contemporary science but also tended to encourage attempts at constructing a racial hierarchy of white peoples.

This article examines the articles on human nature and mankind's physical and cultural diversity published in the Warsaw highbrow journal Biblioteka Warszawska in the first phase of its history, 1841–1864, i.e. prior to the Darwinian revolution in the natural sciences. It was a period when anthropology was trying to establish itself as a separate discipline by drawing on the dominant Romantic conceptions of natural evolution and the authors of Biblioteka Warszawska would often use them as a scientific underpinning of their articles.
