Drawing on historical, theoretical and cultural knowledge, this introduction explains and justifies the importance of generalisation from dialogical single case studies. We clarify the meaning of dialogism and dialogicality, differentiate between single case studies and dialogical single case studies, identify the dynamic and ethical features of dialogical single case studies, and articulate the problem of generalisation as it pertains to this topic. We suggest that the question of generalisation ought to be viewed as an effort to resituate knowledge and its dialogical features, for example values, ethical standards or levels of engagement, in other dialogical single case studies.
Dialogism and dialogicalityThroughout historical and cultural development, language and symbolic communication have been vital for humans' evolving capacities to conceive themselves and others as beings who can think, who have knowledge and beliefs, who experience, use symbols, tell stories, and otherwise. Individuals, groups and societies create intersubjective bonds, struggle for their social recognition, and evaluate and judge their intentions and actions. These capacities not only privilege speech and symbolic communication as vital, but they also have ethical qualities. Although these capacities have been concerns of humankind throughout history, with the emergence of the social sciences in the 18th century, they became the subject of explicit research. Among scholars, Giambattista Vico (1668-1744) emphasised the inventive power of language and the ethical nature of common sense thinking. Johann Gottfried von Herder (1744-1801) viewed language through the power of self-consciousness and self-realisation. Wilhelm Humboldt (1767-1835) conceived of language as an organic whole, which is never a finished product but an everchanging and dynamic process. We could view such scholars as predecessors of the concepts of 'dialogical existence' and 'dialogical thinking', which were later developed in the post-Hegelian Marburg School, Bakhtin's dialogism, Vygotsky's sociocultural approach, and American pragmatism. These theoretical influences led, during the second half of the last century, to the development of a number of approaches in which dialogue has become the central concept and thus, such approaches often call themselves 'dialogical'. At the same time, the emphasis on dialogue, in which professionals and clients/patients mutually co-construct meanings of their concerns, has become influential in professional practices such as psychotherapy, family therapy, and the care of people with communication difficulties. Moreover, the focus on mutualities in dialogue has penetrated other domains of social interactions, for example in education, services and politics.The main presupposition of dialogical perspectives is that the mind of the Self and the minds of Others are interdependent in and through the sense-making and sense-creating of social realities, in interpretations of the past, experiencing the present and imagining the future.
