On the non-necessity of quantum mechanics in geomorphology

The recent paper by Harrison and Dunham raises a number of issues relating to the current debate on the philosophies that could (or should) inform research in geomorphology. In our view, the interpretations given by Harrison and Dunham of realism and idealism are deeply flawed. However, more important than any reservations we may have concerning their interpretations of philosophical frameworks are our reservations concerning their interpretation of the links, or otherwise, between quantum mechanics and geomorphology. We therefore propose to deal only with the latter issue here, and intend to return to the debate on philosophical issues in a subsequent paper.
