I did not see a thread on the 6-17-12 Wt Study article, so I thought I'd put this here.
This is just a thought on unquoted references that sheds a little "light" on why they are not sourced.
In paragraph 4 of the lesson it says: 'As one reference work states, it is "the sum total of the interior man."' It is referring to what the Bible means when it speaks of the figurative heart. One of the things that was interesting about this is that this is the definition that was given at the DC. So it was interesting to see this in the WT so soon. This new or expanded WT understanding of the figurative heart makes a lot of sense. So that was nice to see.
If you do not know about the older understanding the WT had, it is something like this: At one time - and not all that long ago - the WT taught that the "heart" always referred to the actual organ. And since the Bible mentions thoughts and other mind-like activities with the heart, it was thought that the heart had brain cells in it. I think this idea lasted till sometime into the 70s or early 80s.
After this, the Society taught that mention of the figurative heart referred to the motives. Now, the definition is greatly expanded to mean "the entire inner man," as the quote above indicates. And when comparing the many verses that refer to the heart, this makes a lot of sense.
But now for that pesky quote ...
I did a search on google books looking for it. It led to this page. As best as I can tell, the quote comes from a book called "The Metaphorical Use of the Names of Parts of the Body in Hebrew and in Akkadian" by E Dhorme, Paris 1963 pp.113, 114, 128 (That title is a mouthful.)
Anyways, on that same page was another quote for the figurative heart. Here it is copied from the page:
It is said to stand for "the central part in general, the inside, and so for the interior man as manifesting himself in all his various activities, in his desires, affections, emotions, passions, purposes, his thoughts, perceptions, imaginations, his wisdom, knowledge, skill, his beliefs and his reasonings, his memory and his consciousness."-Journal of the Society of Biblical Literature and Exegesis, 1882, p. 67.
Basically these two quotes are the same thing that the WT is saying as "new light" about the figurative heart. But look at the dates of these references: 1963 and 1882! The Society could have known this stuff way back.
So much for "food at the proper time."
