It has been nearly fifty years since Mikhail Mikhailovich Bakhtin (1895-1975) put forward the term "dialogic imagination" in the title of his four essays on language and the novel, thereby announcing a new direction in linguistic and literary research. In the present volume, we revisit Bakhtinian (and marginally Buberian) thought from three perspectives: discourse, literary text, and interaction in educational settings. It is how we intend to pay tribute and homage to the diversity and universality of his ideas to testify to their unquestionable versatility and fertility.
