We must plant the sea and herd its animals using the sea as farmers instead of hunters. That is what civilization is all about - farming replacing hunting.

If human civilization is going to invade the waters of the earth, then let it be first of all to carry a message of respect.

The sea, once it casts its spell, holds one in its net of wonder forever.

The impossible missions are the only ones which succeed.

I swam across the rocks and compared myself favorably with the sars. To swim fishlike, horizontally, was the logical method in a medium eight hundred times denser than air. To halt and hang attached to nothing, no lines or air pipe to the surface, was a dream. At night I had often had visions of flying by extending my arms as wings. Now I flew without wings. (Since that first aqualung flight, I have never had a dream of flying.)

I am absolutely enraptured by the atmosphere of a wreck. A dead ship is the house of a tremendous amount of life-fish and plants. The mixture of life and death is mysterious, even religious. There is the same sense of peace and mood that you feel on entering a cathedral.

There are a few animals that have won themselves a bad reputation even though they have little or no effect on man. They have won their rating through man's interpretation of their attitude towards lower animals. These animals have been seen feeding in what appears to be a savage manner. But this behavior may perhaps be comparable to a man tearing the flesh off a chicken leg with his teeth.
