Theory and practice are two sides of the same coin: they are inextricably linked. In this second edition of his classic text, Neil Thompson revisits the crucial topic of integrating theory and practice - this time, widening his scope to explore the importance of informed practice not just in social work, but across the full range of human services: from nursing and counselling to youth work, community studies and beyond. Thoroughly revised and updated, the new edition uses detailed explanations, practitioner quotes and engaging practice examples to guide the reader through the process of 'theorizing practice'. With his peerless clarity and flair for tackling advanced concepts in an accessible way, Thompson critically discusses the approaches and perspectives of the numerous human services, including postmodernism, morality and organizational culture, and brings particular focus to the role of existentialism in understanding the challenges of contemporary practice. This important new edition provides much-needed food for thought about the complexities of theory and practice, and is sure to provide fresh inspiration to professionals and students alike.
