Selected Writings (Lakewood, 1988)
This powerful and revealing quote by R. Schwab doesn't get publicized as often as it should, even on the various Jewish skeptic blogs. So bear with me while I mention it here.
You can find this potent quote in Rabbi J.J. Schacter's article, Facing the Truths of History. Lots more goodies therein - grab it while it is still available (it doesn't seem to be accessible via a search on Edah). Meanwhile, I'll leave you with another quote, this one from Abraham Lincoln:
History is not history unless it is the truth.
