On the hadronic problem in QCD

In this talk we try to give a brief review of the current ideas about confinement and the hadron problem in quantum chromodynamics.Invited talk presented at the International Symposium Selected Topics in Quantum Field Theory and Mathematical Physics, Bechyn, Czechoslovakia, June 14–19, 1981.I would like to thank Rod Crewther, Peter Minkowski, William Mecklenburg, Werner Nahm, Jan Stern and John Strathdee for discussions which helped clarify many points in preparing this paper.
