For Isaac

I was talking to my friend Zak today and he said he was wearing his Dogs and Water t-shirt ("not on purpose" he said) and he said his son Isaac asked him what does it mean. So he said he would ask me. I said I didn't feel that I was under any obligation to explain the mystical symbology of my self expression to a six year old. But he said that probably wouldn't be good enough. So this is my best guess. (The above diagramatic explanation is intended for application to the t-shirt image only. Extreme care and subtlety should be employed in extrapolating it to the book as a whole. Such application, while reasonable as far as it goes – more or less – would be woefully incomplete.)
