I think he got it exactly right.
Try reading it again.
OK, I remember one of my pet peeves about Alan Keyes. I now agree that you CAN read that the way he wrote it and it can make sense. But it requires you to swap the meaning of the word “determine” in the 1st and 2nd sentences.
I dislike false parallelism. Maybe because I tend to write down to my audience, and it’s a too-clever (in my opinion) trick.
Of course, I think I just called mself dumb, because I didn’t recognize it earlier.
Oh well.
