In this great crucible of life we call the world—in the vaster one we call the universe—the mysteries lie close packed, uncountable as grains of sand on ocean's shores. They thread gigantic, the star-flung spaces; they creep, atomic, beneath the microscope's peering eye. They walk beside us, unseen and unheard, calling out to us, asking why we are deaf to their crying, blind to their wonder.
Sometimes the veils drop from a man's eyes, and he sees—and speaks of his vision. Then those who have not seen pass him by with the lifted brows of disbelief, or they mock him, or if his vision has been great enough they fall upon and destroy him.
For the greater the mystery, the more bitterly is its verity assailed; upon what seem the lesser a man may give testimony and at least gain for himself a hearing.
There is reason for this. Life is a ferment, and upon and about it, shifting and changing, adding to or taking away, beat over legions of forces, seen and unseen, known and unknown. And man, an atom in the ferment, clings desperately to what to him seems stable; nor greets with joy him who hazards that what he grips may be but a broken staff, and, so saying, fails to hold forth a sturdier one.
Earth is a ship, plowing her way through uncharted oceans of space wherein are strange currents, hidden shoals and reefs, and where blow the unknown winds of Cosmos.
