Who Said It? “any backward chaining engine must eventually…”

I found a quote that James Owen used on the JESS mailing list and I’m interested in learning where it comes from. More specifically, is it in a paper or article somewhere and I’m just overlooking it? My suspicion is that James is quoting Dr. Charles Forgy and that it isn’t published in any articles.

I’ll email James to check the source – but I wanted to highlight the quote here since it was only used on the JESS list and could use a little more exposure.

“Any forward chaining engine can be made to do backward chaining and any backward chaining engine must eventually forward chain to deliver results.”

Updated on January 13, 2010:
James has confirmed (via email) that he was paraphrasing Dr. Charles Forgy here. The comment apparently was made during OPSJ training classes.
