The surface of the Earth is the shore of the cosmic ocean. From it we have learned most of what we know. Recently, we have waded a little out to sea, enough to dampen our toes or, at most, wet our ankles. The water seems inviting. The ocean calls.
Vulgar souls look hastily and superficially at the sea and accuse it of monotony; other more privileged beings could spend a lifetime admiring it and discovering new and changing phenomena that delight them. So it is with love.
Tis better using France than trusting France;
Let us be back'd with God, and with the seas,
Which He hath given for fence impregnable,
And with their helps only defend ourselves;
In them, and in ourselves, our safety lies.
