The person compelled to clown manufactures the appearance of feeling to defend against experiencing his own feelings. He falls into a persona compulsion. The public face he turns to the world comes to substitute for his own, even does so perhaps to himself. Playing roles substitutes for being and owning true self. Thus all the emotion that would naturally be transmitted to his ego for sorting and and translation into feeling, amasses a change of energy that fuels the compulsion to wear masks all the time, getting just the right mask for the occasion, embellishing it, improving it constantly, expanding upon it.
