The Fool represents the superconsious, the next step forward, and unmolded potential. The Fool has pure desires, untainted goals. They're there to remind us, to set us in motion, chaotic but moving forward towards progress of some sort. Their enlightenment can come from anywhere, places where others might not imagine, and often might call them strange for. They're doing what is right for themselves, regardless of the commandments of others, and have faith in themselves. Neither positive nor negative, the fool offers the potential for new experiences and new choices.
