The "decisive machine of the modern industrial age" is the clock (Lewis Mumford). It makes everything measurable and man begins to measure everything with it. Once man gets used to having a fixed time, he hardly will be able to resist it, and thus it is easy to connect him to a steam engine which gradually but constantly accelerates. Consequently, the factual constraint of technology is increasingly internalized until people restrain themselves willingly and surrender to it. At this point, nobody wonders whether the self-restraint is due to technology or who is the Master of the unspoken societal restraints. Perhaps it is all too simple: Time Is Money.
