I remember a TV program in which Barbara Walters got in a debate with Justice Scalia over the death penalty - Barbara was hopelessly outmatched. My confronting Safire about an issue of English grammar would put me in the same situation. Besides I hold a clear bias against the Duck and for Safire. In fact I feel a bit silly defending Safire, because I know he would do a much better job. The constitution is basically a legal document, and lawyers use the verb perFECT in Safire's secondary sense: to perFECT a deed does not mean that you make it PERfect. Furthermore, I presume the founding fathers and mothers were intelligent educated people who put considerable effort in to the preamble, so it seems unlikely that an obvious false comparative would escape notice.
P.S. As an afterthought it seems that the notion that Job was a perfect man does not jibe with original sin. I am not open to discussion of this idea, because as it happens I do not believe either side is right.
