From USS Constitution, NCC-71000 (Galaxy-class)
"...to defend the liberty of the citizens of this Federation, and to spread its benefits..." From the original speach by President John Ford of the UFP on the christening of USS Constitution, NCC-1700.
USS Athena, NCC-65809 (Arika-class)
"Wisdom, science, and defense"
USS Shenandoah, NCC-1950 (Constitution II class)
"We return to the stars..."
"War is an ugly thing but not the ugliest of things; the decayed and degraded state of moral and patriotic feelings which thinks that nothing is worth war is much worse. A man who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself."
John Stuart Mill
