Up the coast a few miles north, in a lava reef under the cliffs, there are a lot of rock pools. You can visit them when the tide is out. Each pool is separate and different, and you can, if you are fanciful, give them names, such as George, Charlotte, Kenny, Mrs. Strunk. Just as George and the others are thought of, for convenience, as individual entities, so you may think of a rock pool as an entity; though, of course, it is not. The waters of its consciousness - so to speak - are swarming with hunted anxieties, grim-jawed greeds, dartingly vivid intuitions, old crusty-shelled rock-gripping obstinacies, deep-down sparkling undiscovered secrets, ominous protean organisms motioning mysteriously, perhaps warningly, toward the surface light. How can such a variety of creatures co-exist at all? Because they have to. The rocks of the pool hold their world together. And, throughout the day of the ebb tide, they know no other.
