What is wrong with these two orthodoxies? The explanatory orthodoxy is so concerned to rush to an explanation that it fails to ask serious questions about what it is explaining. There is a parallel here with what we must now call a ‘postmodern’ phenomenon. It seems that visitors to the Grand Canyon in Arizona are now freed from the messy business of exploring the canyon itself. Instead, they can now spend an enlightening hour or so in a multi-media ‘experience’ which gives them all the thrills in a predigested way. Then they can be on their way, secure in the knowledge that they have ‘done’ the Grand Canyon.
