Yes. Thomas Aquinas and I suppose Aristotle as well consudered the argumant from authority to be the weakest.

I worked on a labor crew at an oil well equipment manyfacturer's factory one summer. I heard an argument between two of my compatriots that ended thusly: "If you don't believe me just ask Joe" said one. "Why should I ask him? He'll just say the same thing you're asayin, and I know you're alyin'" said the other. I'm sure neither was a Thomistic scholar, but at least one had the right idea.
