This is really going back. I've been spending some time searching for where I first heard this comment made with regard to UNIX.
Memory is telling me that it was in the Edition VII days, back around 1979-84ish, and that it was perhaps one of ("Dennis Ritchie", "Ken Thomson", "Brian Kernighan", "P.J. Plauger"), or maybe even Rob Pike or Steve Bourne. I have had no luck with google or any documentation I've got. The statement was in the context of the "UNIX Philosophy".
If anyone can point me at a reference I'd certainly appreciate it.
