The Vulcan Science Directorate dogmatic views are not logical, and proves that Vulcans are full of shit when they claim to be ruled by logic. In reality their main driver is fear (even that’s what drives them to try to suppress their emotions).
I seem to recall some of the Romulans saying something very similar to Ni’var Science Directorate vulcans’ faces in the episode Unification III.
