Post-truth is not something new; what we now call “post-truth” is a well-known phenomenon, called “lie” or “gossip”. Gossip and slander are dangerous tools for controlling people’s behavior. When a lie is told many times, it does not come true, but its repetition changes perceptions, creating an illusion about a fact, always at the service of power. Power is the opposite of love, as Jung stated, but it is also the opposite of Truth, as Gandhi said.
