Great classics of philosophy revisited for an easier interpretation series Who among us does not have rivals? Plutarch writes about it as easily as only great communicators do, and explains how to treat those who are not on our side. In "De capienda former inimicis utilitate": "How to profit by one’s enemies," the great philosopher introduces his thought with irony but also with overwhelming logic, revealing an infallible system for winning in a confrontation with one’s enemies. Rules conceived long ago, but which are relevant more than ever. A great help to improve our relationships with others. THE AUTHOR Plutarch was a writer and philosopher in ancient Greece. He was born at Chaeronea, in Southern Greece sometime around AD, during the domination of the Roman Empire. Later, he moved to Athens and began his studies in philosophy and mathematics. He travelled a lot, in Asia and then Rome, where, thanks to his prestige, he gained honorary positions which he held once back in Greece. His works are numerous and they reveal his huge culture; Plutarch wrote about everything, driven by his curiosity and the desire to investigate human nature and the human mind from every angle. His subjects, still incredibly relevant today, inspired famous authors such as Shakespeare, Alfieri and De Montaigne.
