In the first part of the book Ewa Bińczyk discusses postulates that have been formulated in response to the problem of the unwanted consequences of the practical success of technoscience (deriving mainly from science and technology studies). In the second part Tomasz Stępień analyses nanotechnology as example of technoscience development and presents the nano-assessment framework.

The presented analyses are focusing on three predominant theoretical approaches in the philosophy of science and technology: technoscience (STS), technology assessment (TA) and converging technologies (NBIC). On this base are extrapolated the coordinates of the heuristics of technosciences.

This article considers the issue of changes in the understanding of symbols as an integral part of spiritual life in Neoplatonic philosophy. It seems that ancient Neoplatonic philosophers were the first who clearly realized the importance of symbols to spiritual life. However, it happened due to the influence of the mystical Chaldean and Egyptian thought transferred to philosophical investigation by the Chaldean oracles and Corpus hermeticum. The late Neoplatonic thought of Iamblichus and Eastern Neoplatonic schools used symbols and rituals as (...) integral parts of philosophical investigation, understood as having a mystical goal. Especially mathematical symbols played a significant role, because they were used in the most advanced theurgical rituals. This analysis of the pagan Neoplatonic philosophy permits us to show properly the thought of Pseudo- Dionysius the Areopagite, who creatively transformed the teaching of his pagan predecessors, by incorporating ancient Neoplatonic tradition into Christian theology. Pseudo-Dionysius excludes liturgical symbols from the order of the cosmos and transfers them to the plane of Salvation grounded in Biblical Revelation. Only true symbols are used in the liturgy of the Church, and thus mathematical symbols are no longer needed in the ascent of the soul to unity with God. The third part analyzes the meaning of symbolism in the thought of Nicolas of Cusa. Thanks to the rediscovery of ancient pagan Neoplatonism and Pythagorean thought, Cusanus also brings new life to the mystical meaning of mathematics. Mathematical symbols once again become an im- portant part of the mystical ascent of the soul, but this time without their ritual context. (shrink)
