One is never alone with a rubber duck explores the premise that Douglas Adams’s Hitchhiker Series is not merely characterised by light-hearted comedy, but is underpinned by intricate philosophical ideas, especially those of twentieth century Existentialism and the related notion of absurdity. It also investigates the interlaced functions of Adams’s fantasy and landscapes of alterity, and considers the ambiguous concept of madness as subjective reality. Concepts related to alterity, such as simulation, the structure of reality, dreaming and parallel universes, are investigated as part of Adams’s fantastic story space.
In a science-fictional sense, Adams’s aliens satirise the human condition and the monstrosities that lurk at the heart of twentieth century society.
