ABSTRACT
Here is an enormous incalculable force … let loose suddenly upon mankind; exercising all sorts of influences, social, moral and politi-cal; precipitating upon us novel problems which demand immediate solution; banishing the old before the new is half matured to replace it; … Yet, with the curious hardness of a material age, we rarely regard this new power otherwise than as a money-getting and timesaving machine … not many of those … who fondly believe they can control it ever stop to think of it as … the most tremendous and farreaching engine of social change which has ever blessed or cursed mankind.
