As Card 0, the Fool lies at the beginning of the major arcana, but also somewhat apart from the other cards. In medieval courts, the court jester was someone who was not expected to follow the same rules as others. He could observe and then poke fun. This makes the Fool unpredictable and full of surprises. He reminds us of the unlimited potential and spontaneity inherent in every moment. There is a sense with this card that anything goes - nothing is certain or regular. The Fool adds the new and unfamiliar to a situation.
