This text describes the process that led to knowledge as becoming the most important modern good and a complex phenomenom beginning at the end of the 19th century.  It was a change in the way of understanding the world proposed by mathematics and geometry. This volume reveals how the paradigm shift, still in progress, is gradually transforming less obvious fields of science, such as the humanities and social sciences, while affecting the phenomenon of knowledge. Firstly, meta-analysis gained in importance, and secondly, it became natural to perceive knowledge in a social context, showing its diverse and multi-cause dispersion, leading to the phenomenon of knowledges. Due to the interpretation of knowledge as a complex social phenomenon, the author proposes a new model of knowledge description, called the theory of discursive space, making it possible to describe the role and meaning of knowledge as a component of modern civilization that is all encompassing. This text appeals to students and researchers working in philosophy of technology.
