Progress is man's mode of existence. The general life of the human race is called Progress, the collective stride of the human race is called Progress. Progress advances; it makes the great human and terrestrial journey towards the celestial and the divine; it has its halting places where it rallies the laggard troop, it has its stations where itmeditates, in the presence of some splendid Canaan suddenly unveiled on its horizon, it has its nights when it sleeps; and it is one of the poignant anxieties of the thinker that he sees the shadow resting on the human soul, and that he gropes in darkness without being able to awakenthat slumbering Progress.
