Any archeologists around? Know what the term "the principle of the sloping horizon" means in the following context?
"Cultural evolution was multilinear and not always evenly paced in each line. Both homotaxis and the principle of the sloping horizon as regards the diffusions are demonstrable in the archeological record. Certain cultural lines did not contain each of the levels of an ideally complete ascending classificatory scheme."
