Tonight on (I expect) many PBS stations you can see a documentary called ” First Freedom: The Fight for Religious Liberty .” (It’s on from 8:00 to 9:30 p.m. on Philadelphia’s WHYY; check local listings.) I am not endorsing the program, since I want to see it first, but I am heartened by learning that two friends of mine appear in it, Robert George of Princeton and Matthew Holland of Utah Valley University.
