The history of humanity is intimately linked to communication and has given rise to societies in which communication skills are essential for coexistence and progress. Every day, although sometimes we are not aware of it, we learn new ways to communicate. Communication surrounds us, soaks us, and is a fundamental part of our personality. And this scenario, in which the presence of communication is constant, requires an intense exercise in adapting to new messages and new ways of communicating. Philosophy is often branded as incomprehensible discourse or for scholars, and yet philosophical theories contain simple magisterial formulas that help us to better orient ourselves in the new communication scenarios. Ockham's razor, can it be used on Twitter? Does Plato's cave have something to teach us about the Internet and new technologies? This book transits between philosophical theories, and extracts from them small practical pearls to better understand the world in which we live.
