All people have an interpretation of the world. Interpreting is already a genuinely philosophical task. Therefore, all women and all men are philosophers and cannot stop being so without resigning from their human condition. This universal philosophical activity coexists with the efforts of a small minority of individuals who write philosophy books. The best of these philosophical works are those that, due to their intelligence, depth and persuasive force, help to educate and improve that first natural philosophy of the people. The supreme mission of philosophy today is to become worldly: philosophy about the whole world but also for everyone and, if possible, with a little bit of the world. A philosopher should not address his writings only to other philosophers, but to the ordinary, unspecialized citizen who wishes to live his life in a wiser, more meaningful, more worth living way. And he has to carry out this important task, in addition, with good literary style, as a man of the world who masters the art of delighting, intriguing and moving his reasons to the grateful audience. Worldly Philosophy is a book that ignores merely philosophical problems -those that only professionals of the discipline are interested in- and chooses as its theme the issues that concern us all -individuality, beauty, fortune, love, happiness, the enigma of life, death-, projecting on them, yes, the luminosity of a philosophical gaze. And for this purpose, he cultivates a genre, the microassay, where brevity, entertainment, personal anecdote and humor are put at the service of a modern, profound and original approach to eternal questions of human existence. This book brings together Javier Gomá's microassays contained in Todo a thousand and Reason: goal and completes them with others that are collected here for the first time.
