Did you know that Engels, the main philosopher of communism along with Marx, left an inheritance of millions of dollars? Or that Spinoza's books were burned at Oxford University shortly after their author's death? And that Saint Teresa of Jesus is considered the first great feminist in history?

Did you know that among the philosophers that Sanzio painted in his fresco on Plato's Academy, there is a woman? And that this woman was murdered by a mob of Christian fanatics who skinned and dismembered her? Did you know that the latest revealed religion is "pastafarianism", the supernatural belief in a god identified as a bunch of spaghetti and meatballs? And that in Davos, where the most important economic and political summit in the world is currently being held, two of the greatest philosophers of all time faced each other, one of them a fervent supporter of Adolf Hitler?

The vision of philosophers that has always been instilled in us presents them as if they lived on little less than air, permanently engrossed in their ramblings and theories and far from the earthly world. But the truth is that very often they have risked their lives to defend their ideas, the freedom to express them and have advocated the creation of a freer and more just society. Many of these great philosophical disputes are collected in this book by Santiago Navajas (author of titles such as From Nietzsche to Mourinho or Technological Man and the Blade Runner Syndrome), which approaches the History of Philosophy from a prism that is absent in books conventional text.

"It must be said about Santiago Navajas that it is impossible not to think while reading him"
Luis I. Gomez

"Santiago Navajas, despite being a philosopher and writing (film) in newspapers, practices with the truth"
Arcadi Espada
