Kaplan the Bible Critic

From Mordecai Kaplan's Communings of the Spirit, entry from Sunday, April 21, 1929, 12:30PM.

Is it possible that I have made a discovery? I have a hunch that the writings of the "false" prophets have been incorporated into the Bible. I can never find a satisfactory background for Isaiah 13 and 14. Does it not seem plausible to assign these chapters to the so-called "false" prophets whom Jeremiah denounced (Jer. 29, 8)? May this not be the reason for the anonymity of these prophecies? If it should turn out that the "false" prophets were the authors of the anti-Babylonian prophecies, they would have to be credited with the new consolatory trend that we find in Biblical prophecy. It does not seem plausible to ascribe such lofty style and diction to any but the survivors of the great prophetic movement who had been carried captive into Babylon.
