When we go down to the low-tide line, we enter a world that is as old as the earth itself - the primeval meeting place of the elements of earth and water, a place of compromise and conflit and eternal change.

Every mystery solved brings us to the threshold of a greater one.

the sea is a place of mystery. One by one, the mysteries of yesterday have been solved. But the solution seems always to bring with it another, perhaps a deeper mystery. I doubt that the last, final mysteries of the sea will ever be resolved. In fact, I cherish a very unscientific hope that they will not be.

The human race is challenged more than ever before to demonstrate our mastery, not over nature but of ourselves.

Nowhere on the shore is the relation of a creature to its surroundings a matter of a single cause and effect; each living thing is bound to its world by many threads, weaving the intricate design of the fabric of life.

The edge of the sea is a strange and beautiful place.

The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.
