Klingon philosophy
From Memory Alpha, the free Star Trek reference
Klingon philosophy is most notably a warrior's philosophy. A Klingon's moral goal is the achievement of honor, mostly through battle. This is comparable to the Earth-based martial philosophy of such countries as China, India and Japan, although with significant differences. Klingons also have a complex religious philosophy upon which their martial philosophy is based. The most notable contributer to this system was Kahless himself. The Klingon oath of 'sacrifice, strength, duty' displays the three primary qualities that are valued above all else within Klingon warrior society.
[edit] Background
Writer Ronald D. Moore, who has defined much of Klingon culture, has commented at length on Klingon philosophy.
When preparing the script for "Sins of the Father", he wrote a memo defining his take on the Klingons. He compared them "the Samurai of feudal Japan, the Vikings, and the Hell's Angels." (AOL chat, 1998)
While writing for Star Trek: Deep Space Nine, he elaborated more here and here.
