Phillip E. Johnson says, “his intent never was to use public school education as the forum for his ideas [Intelligent Design creationism].” Wesley Elsberry has a flock of quotes direct from Johnson that refute that.
If it were someone other than Johnson, I’d say he was just lying…but he’s old, he’s had a serious stroke, so it’s entirely possible he’s merely senile or brain-damaged. No matter what, though, it means you can’t trust Phillip E. Johnson to speak the truth.
