The world has never been as materialistic as it is today, and yet so frivolous and cowardly psychic. Witches who read cards, hypnotists, mediums, spiritualists, suggestionists, sorcerers, healers, charlatans of all kinds, are present everywhere. They are seen as much in slums as in palaces, as much in public as in secret. People believe in the absurd, in the fanciful, and a rare collective madness runs from side to side of the planet.
