How does Dickens make his readers laugh? What is the distinctive character of Dickensian humour? These are the questions explored in this book on a topic that has been strangely neglected in critical studies over the last half century. Dickens\047s friend and biographer John Forster declared that: \047His leading quality was Humour.\047 At the end of Dickens\047s career he was acclaimed as \047the greatest English Humourist since Shakespeare\047s time.\047 In 1971 the critic Philip Collins surveyed recent decades of Dickens criticism and asked \047from how many discussions of Dickens in the learned journals would one ever guess that (as Dickens himself thought) humour was his leading quality, his highest faculty?\047 Forty years later, that rhetorical question has lost none of its force. Why? Perhaps Dickens\047s genius as a humourist is simply taken for granted, and critics prefer to turn to his other achievements; or perhaps humour is too hard to analyse without spoiling the fun? Whatever the reason, there has been very little by way of sustained critical investigation into what for most people has constituted Dickens\047s special claim to greatness.\012This book is framed as a series of essays examining and reflecting on Dickens\047s techniques for making us laugh. How is it that some written incident, or speech, or narrative \047aside\047 can fire off the page into the reader\047s conciousness and jolt him or her into a smile, a giggle, or a hearty laugh? That is the core question here. His first novel, Pickwick Papers, was acclaimed at the time as having \047opened a fresh vein of humour\047 in English literature: what was the social nature of the humour that established this trademark \047Dickensian\047 method of making people laugh? And how many kinds of laughter are there in Dickens? What made Dickens himself laugh? Victorian and contemporary theories of laughter can provide useful insights into these processes - incongruity theory or the \047relief\047 theory of laughter, laughter\047s contagiousness (laughter as a \047social glue\047), the art of comic timing, the neuroscience of laughter. These and other ideas are brought into play in this short book, which considers not only Dickens\047s novels but also his letters and journalism. And to that end there are copious quotations.\012The aim of the book is to make readers laugh and also to prompt them to reflect their laughter. It should have an interest not only for Dickensians but for anyone curious about the nature of laughter and how it is triggered.
