This episode makes it seem like Vulcans treat logic the way Klingons treat honor. Something to be proud of and that makes them superior to other races but can be thrown away when it's inconvenient.
The Vulcan makes a crack about humans evolving from apes when a few thousand years ago they were about as savage as humans at their worst. And of course we all know this ends up in a ritual where betrothals are challenged by fights to the death, obviously a traditional holdover from their savage period.
The truth emerges between this, and the way Vulcans were portrayed in DS9. Logic is not a way of life so much as a security blanket, a placebo to protect them from their worst instincts. They suppress their emotions on the belief that the only way to win the fight is to deny the battle, and are only coming to realize that by the time of the 24th century, much like for the humans, the battle has already been won.
