The game of the being is a game of hide-and-seek called paradox. And this is a paradoxes book, full of definitions that put us back in the starting point of its curiosity. Kind, acid, bitter, impudent and contradictory texts, with big sense of humor, born from a mental flash suffered during a purposeless evening. Antonio Alvarez-Solís has made his the long multicultural tradition of aphorisms, haikus or greguerías and he passed on to us a very vital book, written with a very personal touch; because the real life of the things often hides behind them.
