Abstract: We give an introduction into quantum cosmology with emphasis on itsconceptual parts. After a general motivation we review the formalism ofcanonical quantum gravity on which discussions of quantum cosmology are usuallybased. We then present the minisuperspace Wheeler-DeWitt equation andelaborate on the problem of time, the imposition of boundary conditions, thesemiclassical approximation, the origin of irreversibility, and singularityavoidance. Restriction is made to quantum geometrodynamics; loop quantumgravity and string theory are discussed in other contributions to this volume.
