" Vital art comes always from a cross between art and life: art being of one sex only, and quite sterile by itself. Such a cross is always possible; for though the artist may not have the capacity to bring his art into contact with the higher life of his time; fermenting in its religion, its philosophy, its science, and its statesmanship (perhaps indeed their may not be any statesmanship going), he can at least bring it into contact with the obvious life and common passions of the streets. "

― George Bernard Shaw ,
