This book is the first of its kind which defines wisdom as information and the highest level of the cognition units set, composed of data, information, concept, knowledge and wisdom. The author has founded his theory of wisdom on the following assumptions: Any sane person can make wise decisions throughout their lifetime, from childhood to old age; Wise decisions need not be expert in nature; Wisdom ought to be defined in such terms as to be understood not only by experts but by an average man; Wisdom is not synonymous to intelligence; The wisdom of a given human being decides between two systems controlling man: the biological evolution (by the cross-generational chain of genes) and spirituality, whose acquired system of virtues and values influences the actions of man; Wisdom has a range of bandwidth and properties; Knowledge on what constitutes wisdom is not the same as the process of becoming a wise man. Without good life practices, one cannot be a truly wise man; Wisdom ought to be taught in schools and at colleges, since if one waits until old age to become wise, it is commonly too late to redirect ones unwise behaviour into a wise life; Wisdom is a certain kind of information; Wisdom is the most important civilisational resource and should be monitored in a way that is similar or even better than the way you monitor the use of energy, the development of population or other resources. The book is full of examples taken from real cases of applied wisdom by famous people. The review of applied wisdom is provided in the historic context as well in the interdisciplinary approach. Every person who would like to be not only informed and knowledgeable but wise should read this book and applied its recommendations.
