In Writings on Cities Henri Lefebvre calls for a‘renewed right to urban life’. He maintains that‘we must thus make the effort to reach out towards a new humanism, anew praxis, another man, that of urban society’. City spaces are usedin a number of contemporary Irish site-specific theatre productions to explorehistories of oppression and social injustice, and to imagine a new humanistpraxis for society. The international multi-artform production TheConquest of Happiness (2013) was inspired by BertrandRussell’s commitment to human happiness in defiance of war andsuffering in his book The Conquest of Happiness (1930) and inhis many political and philosophical writings. In this article Eva Urbancritically examines the ways in which the performance in Northern Irelandattempted to embody Russell’s humanism and related critical conceptsto encourage active citizenship. She considers to what extent the dramaturgicaloptions employed inthe production applied Russell’s ideas and thoseof other thinkers by developing critical representations of inhumanity,challenging authoritarianism, and exploring humanist ideals.
