In 17th Century English plays (e.g. those of Shakespeare), the role of the Fool was often to stir things up and challenge perceived reality. Others were prevented from such an approach to life because of their fear of the consequences of upsetting the norms of their environment and the powerful people around them. The Fool could get away with his behaviour because of the self-aware authenticity of his humble character and his trusting, even affectionate, relationship with the person he served.
Within the spontaneous and gentle precision of his humour, the Fool’s patient wisdom – presented as an apparent worldly ignorance – enabled others to vent their uncertainties.
