Versions in English, Spanish and Portuguese.On November 16, 2016, the Oxford Dictionary added the word post-truth and chose this entry as "the word of the year 2016".Five years earlier, however, the philosophical system of the writer Daniel Aço already spoke about the basic idea of post-truth: that beliefs overlap, to a certain extent, reason.And this book is the basis of Daniel Aço post-truth conception.Two paragraphs of the book, the synopsis and the author: "Even so, an incredible confirmation appeared in my mind: is more feasible to prove soul immortality, by the approach of electromagnetic waves and by the use of special cameras and devices in vacant houses, for example, than obtain irrefutable certainties by the study of the philosophical ontology. In the ontology field, EVERYTHING, NOTHING and A FEW THINGS are possible. The philosopher Sartre, for example, emphasized nothing. Martin Heidegger, in turn, emphasized what he called Dasein (being there). In the end, truth be told, at light of the spirituality, Mr. Sartre was only nothing and Mr. Heidegger was only anyone, just being there, both lost in redundant, circular and practically empty philosophies. In the same way, since philosophers always denounce their personality by their philosophies, Nietzsche put himself above good and evil, and Hegel supposed to have a very personal access to Absolute (because he was schizophrenic, a reason why he deserves even more compassion by us).""I am not ashamed of being spiritist or spiritualist, neither if I were a mason or a Rose-Cross member. On the contrary, I would be ashamed of hiding in the Hegel's history philosophy to justify the hideous crimes of a barbaric, hypocritical and cruel Christianity."Daniel Aço is a Brazilian spiritualist thinker and writer. He was born in 1976 and lives in Porto Alegre.During a long time, the author defined himself as a free thinker. Today, not giving up such solid definition destined to good.Western thinkers, the author prefers to be a thinker with freedom. In English language, Daniel Aço means Daniel Steel. The Providence wanted that a man with the steel strength was able to expose the truths said in this book, which, in its first month, deserved a translation into Spanish and into English.This book is about a unique work, because it involves a combination and a critic interpretation about the Western Philosophy at light of the spiritual scholars and the spirituality in general. Daniel Aço is the first to do it, and does it with the mastery owned by him, fighting for the philosophical freedom of the goodwill humans, before the presumptuous academic world and the famous philosophical systems.However the author says that he doesn't mind if his work is original, or if it will sell two or twenty million copies, the work is innovative, even because exposes the alleged superiority of the Western philosophers and inserts the Spiritist Doctrine in the Western knowledge.Its language is literary and there is a little bit of everything in its pages: literature, religion, psychology, metaphysics, moral, spirituality, cabala, philosophy, politics, sociology, ufology, science, causality, relativity, energy, mediumship, freedom, karma, reincarnation, satire, and much more. Finally, being a little biographic, the book can be a self-help book, for the person who reads it.Nobody finishes reading this book as an untouchable being, not even its antagonists. Regarding them, by the way, the author doesn't really care - also because he will sell, alone, more copies than all these antagonists together.
