Hans Cloos Quotes

It was during my enchanted days of travel that the idea came to me, which, through the years, has come into my thoughts again and again and always happily-the idea that geology is the music of the earth.

For a billion years the patient earth amassed documents and inscribed them with signs and pictures which lay unnoticed and unused. Today, at last, they are waking up, because man has come to rouse them. Stones have begun to speak, because an ear is there to hear them. Layers become history and, released from the enchanted sleep of eternity, life's motley, never-ending dance rises out of the black depths of the past into the light of the present.

The earth is large and old enough to teach us modesty.

The well-marked path to knowledge is open to anyone willing to make the effort to follow it, though no one will ever quite reach its end.
