For four hundred years the human race has not made a step but what has left its plain vestige behind. We enter now upon great centuries. The sixteenth century will be known as the age of painters, the seventeenth will be termed the age of writers, the eighteenth the age of philosophers, the nineteenth the age of apostles and prophets. To satisfy the nineteenth century, it is necessary to be the painter of the sixteenth, the writer of the seventeenth, the philosopher of the eighteenth; and it is also necessary, like Louis Blane, to have the innate and holy love of humanity which constitutes an apostolate, and opens up a prophetic vista into the future. In the twentieth century war will be dead, the scaffold will be dead, animosity will be dead, royalty will be dead, and dogmas will be dead; but Man will live. For all there will be but one country-that country the whole earth; for all there will be but one hope-that hope the whole heaven.
