In a rapidly changing world, education is vital for humankind and for the world itself. Education is a contested space. This chapter takes a view of education as being for the good for each person and for the good for humankind. The five broad questions that the book explores are outlined in this chapter, as are key concepts addressed throughout the book, including pedagogy, education, bildung, practice, and praxis. We also briefly introduce the theory of practice architectures. The chapter concludes by providing an introduction to the chapters in the rest of the book.
