All walking is discovery. On foot we take the time to see things whole.

Man is not an aquatic animal, but from the time we stand in youthful wonder beside a Spring brook till we sit in old age and watch the endless roll of the sea, we feel a strong kinship with the waters of this world.

There are no idealists in the plant world and no compassion. The rose and the morning glory know no mercy.

And what a dismal place this world would be!
