This book is a collection of papers (2005-2010) focused on various subjects, but related by a single research issue: developing life, culture and mind as the stages in the evolution of Metagalaxy. Megatrends and mechanisms of evolution are explored in the context of an advanced self-organization model (synergetics; complexity theory). The author pays special attention to the evolution of technologies, violence and non-violence: the papers reveal system dependence between growing instrumental might and the perfection of cultural aggression-sublimation throughout human history. The pattern is illustrated by case studies and verification procedures demonstrating its both destructive and constructive attributes. The results of the retrospective research are used to trace probable scenarios of the global civilization''s future and the conditions for its sustainable development.
