We tend to think that being truthful is as important as possessing the truth. I think that sometimes deception is beneficial. Would you tell a nazi storm trooper which way a Jewish escapee ran? And a major method of survival in in the animal world is deception-by-camoflauge.
You could say nothing at all.
And does this deception in the animal world make a smooth transition into society? Is it really ever necessary to lie, especially since we do not have to struggle, per se, for survival (using pure physical strength), except in desperate situations such as war? Perhaps sufficient, but not necessary, and even that seems dubious.
Also in the instance of the Nazi and excapee, perhaps it is indeed moral to tell the truth or say nothing at all; what would need to be examined first is whether or not lying is moral or immoral, and, if so, when and where?
