Progress is the life-style of man. The general life of the human race is called Progress, and so is its collective march. Progress advances, it makes the great human and earthly journey towards what is heavenly and divine; it has its pauses, when it rallies the stragglers, its stopping places when it meditates, contemplating some new and splendid promised land that has suddenly appeared on its horizon. It has its nights of slumber; and it is one of the poignant anxieties of the thinker to see the human spirit lost in shadow, and to grope in the darkness without being able to awake sleeping progress.
