Romulan philosophy
The philosophy of Romulan civilization involved both complete loyalty to their race as a whole, and the celebration, rather than repression, of instinctual, passionate emotion. More specifically, Romulans believed in loyalty to state and government above one's own needs; within the military, loyalty was directed to the Praetor himself. One was expected to adhere to the Praetor's orders with no thought of personal opinion. () The one philosophy they shared with their mortal enemy, the Klingons, is that there was no greater honor than to die in the service of their nation. This shared belief was known to the Romulans as "the Romulan path to glory." ()

The Romulans also had a belief in their own superiority above all other species that went beyond mere arrogance. Unlike their Vulcan counterparts, Romulans did not hide their emotions. They tended to revel in them, being kind and even loving one moment, yet violent the next. ()
