Latin in Universities

While going on many different college tours, I have found that many universities have latin somewhere in the brochures. Many use latin for their school mottos such as Tulane University, University of Texas, and even Harvard University. Tulane's motto is "non sibi sed suis", which means "not for one's self, but for one's own", University of Texas's motto is "disciplina praesidium civitatis" which means "education is the guardian of society", and Harvard's motto is "veritas" simply meaning "truth". Latin is even used for some of the names of schools. Villanova University is named in latin. Villanova means "new town" in Latin.
