Huh. Very interesting. It seems that DCP has offered up a really elephantine Mopologetic response to this. Check it out:
Daniel Peterson wrote: Now that I have a minute, let me unpack what I've said above.
(1) I would very much like to see the specific questions to which, and the contexts in which, Joseph Fielding Smith wrote his responses. Call me pedantic, but I think such things can make a crucial difference.
(2) No, I would not call Joseph Smith Jr.'s denials of plural marriage "white lies."
(3) But I do believe that there are "white lies," and, more to the point, justifiable lies. (I've brought up this example before: You're hiding Jewish children in your attic. Hauptmann Strasser, of the Gestapo, asks you whether you know where any Jews might be hiding. You answer "No." I say, Good for you!)
(4) Once it's acknowledged that some lies might be justifiable in certain situations, the question becomes more complex. What situations might justify (or even morally require) lying?
(5) Were Joseph Smith's denials justifiable lies? Maybe. Maybe not. Such things can be debated everlastingly.
(6) If, in calm and secure retrospect, sitting comfortably in front of our computers, we conclude that Joseph should not have handled things in some cases in the way that he did, does this prove him not a prophet? No. Nothing in the scriptures suggests that prophets have to be perfect, or to handle every situation perfectly. Several examples in the scriptures suggest quite the opposite.
(7) In his situation, what would I have done? I don't know. Joseph knew that plural marriage could mean his death. And it probably did.
(8) Would disingenuousness or lying on Joseph's part, assuming (for purposes of discussion) that that's what it was, demonstrate that plural marriage came not by revelation but by lust? No. That seems a separate question. Both lust-motivated plural marriage and divinely-directed plural marriage could have left Joseph in a situation where he felt threatened by violence against himself and his people, and in which he concluded that dissembling would be the better course until he (and they) were more secure.
(9) Would even several cases in which Church leaders were less then forthcoming demonstrate a pervasive policy of lying on the Church's part? This is, again, a subjective question. It seems, further, to be linked with the so-called "Sorites paradox," or the "paradox of the heap." When does a lack of perfect forthrightness become lying? How many acts of less than perfect forthrightness does it take to make a person a liar? How many acts of less than perfect forthrightness on the part of how many individuals are required to make an institution to which they belong "dishonest"? What positions, if any, do these individuals need to hold in that institution? And so forth. There seems no obvious black and white answer to such questions.
(10) My strong sense of Joseph Smith, based in particular upon Dean Jessee's collection of his "personal writings," which were not intended for publication, is that he was a fundamentally honest and sincere person.
(11) Can honest and sincere people get into situations where they feel that lying is the only sound course available to them? Yes.
(12) Can lying sometimes really be the only sound course available to them? See (3) and (4), above.
(13) I myself do not think that characterizations of the Church of Jesus Christ of Latter-day Saints as fundamentally dishonest are even close to the truth.
(14) I also do not think, specifically, that the Church has been dishonest about its history, let alone that its many fine and professionally trained historians have been or are liars.
(15) But then, in some circles, I myself am portrayed as a consummate (albeit generally incompetent) professional liar ("lying for the Lord"), so perhaps nothing that I say can be trusted, on this or any other topic.
(16) I would very much like to see the specific questions to which, and the contexts in which, Joseph Fielding Smith wrote his responses. Until I've seen those, I will suspend judgment on this matter, and I will not concede that his answers represent deliberate deception.
(17) If Joseph Fielding Smith's answers don't represent deliberate deception, they certainly don't represent further evidence that the Church as a whole is fundamentally deceptive.
(18) They may not represent further evidence that the Church as a whole is fundamentally deceptive even if they were deliberately misleading. See (9), above.
There are a bunch of different thoughts here sort of jumbled together. He is trying to:
---deflect accusations that Joseph Smith lied
---defuse accusations that the institutional Church is in any way "dishonest"
---issue a CFR for the JFS quotes
---trying to explain how lying is okay sometimes
As Beastie pointed out, it is relatively rare for him to engage in actual, real apologetics. I guess this big posting helps explain why.
