I use this story to point up a major tenet of postmodernism: Our sense of what is real depends upon our perspective. Indeed, we all have our human truths that are vital to us and our socially constructed reality—that’s fine and the way it should be. The point is, we should be extremely leery of declaring these human truths absolute Truth with a big "T."
I recently ran across a wonderful quote by Robert M. Pirsig that illustrates this same human conceit of taking a partial sampling (the extent of our human reality) and declaring it everything. I combined the Pirsig quote with a photograph I took at Ogunquit Beach many years ago.
