The title of this study reflects the intention of its editors to include texts relating to both theories and specific deliberative practices with participatory budgeting as a leitmotiv in a concise study. The basic questions which the theory and practice of public policy try to answer is the question about desires in democratic conditions and at the same time an effective formula for balancing centralization and decentralization in decision-making processes. [] Participatory budgeting, as one of possible variants of deliberation, is one of those phenomena of public life, the quality of which depends on the relations of the parties involved. The shape of these relationships only to a limited extent depends on the ways of their current practice, because these methods are causally conditioned, and the causes lie in cultural constructions. That is why these relations are not easy to study; it is difficult to reach that deep, because it is difficult to both model the conceptualization of the problem and the methodological approach to such research. These are one of the most difficult and, at the same time, the most promising research areas of public policy. We hope that this book will contribute to their partial exploration. [] We hope that our collection of articles will show that governance practices can contribute to strengthening proactive public activities located in the area of the so-called civil democracy.
