Biological species are spatio-temporally localized entities. This fact led to the concept of species as individuals [11], [14], and, at the same time, to the refutation of essentialism in evolutionary biology and taxonomy. On the other hand, molecular biology is compatible with essentialisms of chemistry and physics. The new concept of "historical essences", which is presented in this paper, tries to reconcile antiessentialism of evolutionary biology with essentialism of molecular biology. Historical essences are those parts of genetic information which determine (...) characters relevant for the identification of a taxon. Since membership in a particular taxon is defined by the sharing of the most recent common ancestor, historical essences correspond to the genetic information responsible for the creation of such common ancestor. Historical essences, which are spatiotemporally localized, generate a particular arrangement of spatiotemporally unrestricted processes which lead to the creation, maintenance and reproduction of organisms. These arrangements are results of fortuitous confluence of biological and extrabiological circumstances . In historical essences such a sequence of historical contingencies is "conserved", which allows molecular taxonomy to reconstruct the phylogenetic relationships. The concept of historical essences can be seen as a post-Darwinian modification of the original Aristotleś term of essence - "to-ti-en-einai". (shrink)

According to the author, the dichotomy between the primordialist and the instrumentalist approach to the problem od ethnicity is similar to the classical philoso_phical dichotomy of rationalism versus empiricism. Kant's solution - differentiating between the form and the content of ideas - might be animating for us in overcoming the dichotomy between primordialism and instrumentalism. In a new model of ethnicity the ethnicity is to be analogically divided into its form, i. e. the inner universal emotional structure of our mind, (...) on one hand, and its contingent content, acquired from outside in the process of socialization a enculturation on the other hand. This model is based on Tajfel's theory of the minimal group and on Lorenz's conception of imprinting. (shrink)

The volume presents the views of ten authors from four PostCommunist Central and East European countries (Czech Republic, Slovakia, Poland and Latvia) on the impact of emerging technologies on human condition. They analyse the topic from anthropological, ethical, philosophical, ontological, empirical and legal perspectives.
