This statement is horribly misleading. Being illiterate does not equate with being stupid or uncultured--many of the "barbarian" kings in the Dark Ages, like Theodoric the Great, were great patrons of learning who devoted vast amounts of resources to preserving and propagating Roman knowledge. The only problem with them is that they sometimes neglected to record their own history in their occupation with saving what they could from the ruins of the Western Roman Empire.
(Yes, just the Western Roman Empire. The Eastern Roman Empire remained standing well into the Middle Ages and represented a strong continuity between Roman and medieval times).
Only the monks knew how to read and write. I believe the Romans called them barbarians. After the Roman Empire fell, their was very little left in term of civilization.
This is also manifestly false, since--as I've said before--the "barbarian" kings were often also the most assiduous in preserving Roman knowledge. Even if we restrict ourselves to military history, the patterns of warfare in the Dark Ages were actually not very different from the ones we found in the late Roman Empire. The "barbarian" kings based their power upon their control of former Roman fortifications and walled cities, and were fully capable of taking and defending these cities with the most advanced siege techniques of the day barring the Chinese trebuchet (and they adopted these trebuchets very quickly once the technology had spread to Europe). Their battlefield tactics were sometimes strikingly similar to those of the late Romans, whose armies were mostly "barbarian" anyway; for instance, there are some indications that the Franks were not slow in transforming their infantry from impetuous warbands to fairly well-drilled formations along the late Roman model. Sometimes they got so far as to adapt Roman models to their own needs and circumstances, like the Carolingian Franks' organization of their cavalry (!) into "legions" capable of performing intricate tactical maneuvers and conducting prolonged strategic operations in hostile territory. Let's not forget that the most important military text during the Middle Ages was Vegetius's manual of late Roman warfar--so much that its author's name became almost synonymous with the science of war in the same way that the Chinese couldn't talk about military science without mentioning Sun Zi/Sun Tzu.
That's just on the military side. Many other things survived the fall of the western half of the Empire--like the Roman Catholic church, which itself was an important organ of the late Roman state. Then there were the late Roman estates that eventually formed the model for medieval manorialism. So, generally speaking, there was at least as much continuity as discontinuity between the Western Roman Empire and the so-called Dark Ages in Western Europe.
