An Introduction to Collective Intentionality: In Action, Thought, and Society makes a cogent case for the field's importance, presents its central questions, and introduces the main topics of study. Authors Marija Jankovic and Kirk Ludwig masterfully demonstrate why understanding collective intentions is essential for understanding social dynamics, from everyday cooperation to complex institutional structures. Through clear, accessible prose, readers work through the central questions that define the discipline: How do groups form shared intentions? What distinguishes collective action from parallel individual behaviors? How do social institutions emerge from collective intentionality? While presenting their individualist position, the authors provide a balanced exploration of competing perspectives, ensuring readers gain a comprehensive understanding of ongoing debates and future research directions. Each theoretical concept is grounded in examples that illuminate the practical implications of collective intentionality in our daily lives. Chapter summaries reinforce key concepts, while carefully curated further reading lists promote further exploration of collective intentionality. This book is perfect for students and scholars in philosophy, sociology, psychology, and anyone fascinated by the foundations of social reality.
