Un cuvînt de la Boethius despre muzică
“Thus it follows that, since there are four mathematical disciplines, the others [Arithmetic, Geometry, Astronomy] are concerned with the investigations of truth,whereas Music is related not only to speculation but to morality as well. For nothing is more consistent with human nature than to be soothed by sweet modes and disturbed by their opposites…Thus we can begin to understand the apt doctrine of Plato which holds that the soul of the universe is united by a musical concord. For when we compare that which is coherently and harmoniously joined together within our own being with that which is coherently and harmoniously joined together in sound–that is, that which gives us pleasure–so we come to recognize that we are ourselves united according to this same principle of similarity.”

– Boethius, De institutione musica, 5th century
