„Neither are the progressivists, in present-day America, revolutionaries or enemies of the order. Being "radical" or "progressive" they merely want to continue with greater speed and determination along the established, wrong trail.“

„It is said that as many days as there are in the whole journey, so many are the men and horses that stand along the road, each horse and man at the interval of a day’s journey; and these are stayed neither by snow nor rain nor heat nor darkness from accomplishing their appointed course with all speed.“

„The heavenly bodies move with such regularity, orderliness, and symmetry that it is truly a marvel; and they continue always to act in this manner ceaselessly, following the established system, without increasing or reducing speed and continuing without respite, as the Scripture says: Summer and winter, night and day they never rest.“

„One would have thought that conservatives would care far more about the conservation of the old ecological order, and about protecting their ancestral lands, forests and rivers. In contrast, progressives could be expected to be far more open to radical changes to the countryside, especially if the aim is to speed up progress and increase the human standard of living. However, once the party line has been set on these issues by various historical quirks, it has become second nature for conservatives to dismiss concerns about polluted rivers and disappearing birds, while left-wing progressives tend to fear any disruption to the old ecological order.“

„When the time-table is so arranged as to call for speed nearly equal to the full capacity of the engine, it is very obvious that the risks of failure in making time, must be much greater than at reduced rates, and when they do occur, the efforts made to gain time must be correspondingly greater and uncertain. A train whose prescribed rate of speed is thirty miles per hour, having lost five minutes of time, and being required to gain it, in order to meet and pass an opposing train at a station ten miles distant, must necessarily increase its speed to forty miles an hour; and a train whose rate of speed is 40 miles per hour, under similar circumstances, must increase its speed to 60 miles per hour.“
