This paper is based on a lecture delivered by Antonino Forte (1940-2006) at the University of British Columbia, Vancouver, Canada in the fall of 2002 at my invitation. It was later submitted as a contribution to a volume co-edited by James Benn, Lori Meek, and James Robson. For this purpose, the article was reviewed by Lori Meek, now an associate professor at the University of Southern California. Due to his unexpected passing in the summer of 2006, Professor Forte was unable to fully revise the article in line with the suggestions provided by the reviewer. On the suggestion of Erika Forte, the paper has been presented in this publication as it was left, with only minimal edits provided by Kelly Carlton, an executive editor of this journal. Erika Forte, Norman Harry Rothschild, and I have extensively reviewed this edited version to ensure the preservation of Professor Forte’s authorial voice. Certainly, this is not the final version Professor Forte would have published if alive. Nevertheless, we thought the information might still prove useful for other scholars.
