This book explores the concept of decay as providing the fundamental core of Beckett's work, examining the theme of decay in terms of physical, mental and linguistic deterioration. The word 'decay' is often used by critics in general reference to Beckett's thematic emphasis and philosophical outlook. However, this book explores the idea of decay as the fundamental core of Beckett's work, dominating it thematically, linguistically and artistically. Kathryn White explores Beckett's representation of physical decay, mental and spiritual deterioration and finally the idea that 'decay' is to be found in language itself. This study explores the importance of both theme and form in Beckett's work and considers whether Beckett will, in future generations, be remembered both for his representation of existence and his innovations in language.
