In this afternoon, we live in an increasing momentum of the flow of information that emanates from all directions, and it seems that we suffer from what is similar to "glowing information". But do we really realize what information is? Lucano Floride, founder of the philosophy of information, considers that understanding the concept of information is essential to its roots in mathematics, but it carries great importance in our daily life. In this book, Floridy offers an impressive and inspiring introduction to understanding this pivotal concept. It sheds light on the impact of information in various aspects of our lives, starting with mathematics and genetics, to social and value dimensions, exploring the moral aspects of it in relation to ownership, privacy and ease of access to information.
