What is the main conflict in Four Plays by Eugene Ionesco?

This collection of short works by French playwright Eugene Ionesco portrays life as defined by the philosophy of absurdism, a belief system which suggests there is no order or sense in the ways of either the universe or humanity. This sense of chaos plays out in the characters, relationships and situations of all four plays in this collection, which also develop themes relating to the use of language and the dangers of passion.
