This essay takes two cultural phenomena that are not normally compared, UK football culture and Cuban literary culture, as the foundation for a reflection on the crucial role that mass participation plays in each. ‘The twelfth man’ - a term that usually refers to the home fans that impel a team to victory - is employed here as a metaphor to describe the cognitive, corporeal, affective and moral force of mass physical participation and its impact on the individual, the collective and the institution, be that a global football club or contemporary Cuban society. The essay advocates that paying attention to the dialogic and mutually constitutive relationship between individual, collective and institution, a relationship based simultaneously on identification and differentiation, is key to the harmonization of interests that can underpin the continued effectiveness of any cultural phenomenon, especially in times of rapid change.
