VM44, post 6459: Did Professor Dougherty really say this in his book? *** hp chap. 3 p. 27 par. 16 Where Can You Find Guidance? *** For a long time critics claimed that Belshazzar never existed, but was invented by Daniel. In recent years, however, clay-tablet records have been unearthed and translated that agree with the details in Daniel’s account.For this reason, Professor R. P. Dougherty (Yale University) wrote that the Bible is more accurate than other writings and proves that the book of Daniel was written when the Bible indicates it was.—Nabonidus and Belshazzar
Look on page 199-200 of Dougherty's Nabonidus and Belshazzar, starting with section (i) on page 199. The WTS paraphrased Dougherty's words. He was talking about non-Babylonian records, and he says:
"...of all non-Babylonian records dealing with the situation at the close of the Neo-Babylonian empire the fifth chapter of Daniel ranks next to cuneiform literature in accuracy so far as outstanding events are concerned. The Scriptural account may be interpreted as excelling because it employs the name of Belshazzar, because it attributes royal power to Belshazzar, and because it recognizes that a dual rulership existed in the kingdom. Babylonian documents of the sixth century B.C. furnish clear-cut evidence of the correctness of these three basic historical nuclei contained in the Biblical narrative dealing with the fall of Babylon." [italics are Dougherty's]
See footnote 671 on p. 200 regarding the dating of the fifth chapter of Daniel.
