Some basic properties of magnetic flux tubes are discussed, and Parker's (1976) recent criticisms of earlier papers are answered. It is shown that the helically twisted flux tubes (flux ropes) observed in active regions must be the uppermost sections of submerged ropes whose fields are everywhere greater than 4000 G and that a plausible flow pattern may account for the creation of these flux ropes below the convection zone. Evidence is discussed for the existence of flux ropes made up of numerous twisted flux 'strands' and 'fibers'; it is shown that when a 'stich' in a submerged rope projects through the photosphere, the two separate rope sections untwist to provide an interplanetary blast, an active prominence or minor flare, and active region effects. The untwisted rope sections then 'fray' to form separate spots, knots, and other structures. The behavior of rising and emerging magnetic fields is discussed from the point of view of the traditional (dynamo and related) theory and the flux-rope theory. Some active region problems are discussed, including arch filament systems, moving magnetic features, the stability of some sunspots and their proper motions, and the sunspot energy deficit; all find explanations in terms of the flux-rope model. A broad comparison is made of the two opposed theories of solar magnetic fields and activity, and of the two entirely different approaches used.
