Geologists tell us that in the long processes of the ages mountains have been raised and leveled, continents formed and washed away. Astronomers tell us that in space are countless worlds, many of them doubtless inhabited—perhaps by creatures of a lower type than we, perhaps by creatures of a higher. The magnitude of these changes and of these worlds makes the imagination reel. But on one thing we can rely—the greatness of the human soul. On one thing we can confidently build—the men whose spirit is lofty, divine.

For tho' the Giant Ages heave the hill
And break the shore, and evermore
Make and break, and work their will;
Tho' world on world in myriad myriads roll
Round us, each with different powers,
And other forms of life than ours,
What know we greater than the soul?
On God and Godlike men we build our trust.

Alfred Tennyson.
