For most Americans, progress means accepting what is new because it is new, and discarding what is old because it is old.
Today, the notion of progress in a single line without goal or limit seems perhaps the most parochial notion of a very parochial century.
The wonder is not that so much cacophony appears in our actual individual lives, but that there is any appearance of harmony and progression.
In vulgar usage, progress has come to mean limitless movement in space and time, accompanied, necessarily, by an equally limitless command of energy: culminating in limitless destruction.
