I wouldn't exactly call it intelligent to lie to a court ;) Perhaps another descriptor would be more precise? For that matter, can one be "truly lucid" if one lies in such a manner?
Or to quote Moby Dick ~ "Human madness is oftentimes a cunning and most feline thing. When you think it fled, it may have but become transfigured into some still subtler form..."
Note, I don't question your lucidity. But hope it shows the fallacy of your logic train.
