Henceforward every action will be re-echoed by many unforeseen interests on all sides; it will produce a chain of immediate events- confused reverberations in a closed space. The effect of effects, which were formerly imperceptible or negligible in relation to the length of a human life and to the radius of action of any human power, are now felt almost instantly at any distance; they return immediately to their causes, and only die away in the unpredictable. The expectations of the predictor are always disappointed, and that in a matter of months or a very few years.
