This chapter argues examines in detail four ideas of contemporary museology: the application of the contemporary as a lens for understanding the world; a commitment to the human actor; understanding the world from a situated perspective; and committing to knowledge transparency. Using examples from around the world, but particularly from Sweden, it argues that these four areas of action open the possibility of knowing and remembering well. They should precede any commitment to servicing disciplinary knowledge. The chapter ends with an examination of the Prehistories gallery at Historiska Museet, Stockholm, which brings together these four elements.
