This text deals with various questions and all of them constitute a path that leads to philosophy as an art of living. It is intended for all audiences, since the problems of living are of general interest and must be made accessible to all. In this book, there is no previously traced path whose comprehension requires a progressive reading, from the first to the last page. On the contrary, the offer is varied and is an arsenal of thought-provoking proposals, which are arranged in a certain order but can be combined in many other ways. Each section is brief and is conceived as a piece that can be assembled with others that the reader deems appropriate.This book of philosophy is an open dialogue because it is full of unresolved questions and problems. Thinking is synonymous with investment and pleasure where the fundamental issues of human living are addressed, and these issues challenge our will to power.The invitation, dear reader, is the one Immanuel Kant already made to us: "Dare to think".
