There's a fool born every minute. Thus we all have the potential to play the fool. Be it the trickster fool who tricks and teases in a harmless way or the malevolent trickster who means to guide us astray by tomfoolery. Or as an archetype, the shadow side of the fool has a bright side. One of waking us up to alternatives to the same-old-same.
The fool imparts wisdom with social satire and shows us that we don't always have to take the narrow, culturally/socially/politically defined path. Fools may think out of the box and at the same time mock those who are boxed in by tradition. "Little boxes on the hillside, little boxes just the same." The Fool On The Hill looks down, not necessarily on us, but above us with compassion that we have been mesmerized into believing that the socially accepted ways are the only way.
The jester jests us with gestures of freedom. We can shake off the cloak of illusion and choose to live in a way of kindness and harmony with all beings.
