Ideas are the basic building blocks that construct the world we live in. Yet despite the abundance of literature on creativity and innovation, there has been little reflection on ideas as such, their nature and their working mechanisms. This book provides foundations for a reflection focused specifically on ideas - what they are, how they emerge, develop, interact, gain acceptance and become translated into actions. In doing so the book moves beyond the mainstream approaches, offering new, promising theoretical angles, presenting original findings and initiating a research agenda for a science of ideas. This book provides a fresh perspective on how to conceptualize and study ideas and their working mechanisms by treating ideas as the main object of the study and by bringing together a group of original thinkers, scholars, and philosophers to move beyond the mainstream academic discourse on creativity and innovation.
