Nome was a concept basic to Vulcan philosophy, pertaining to the combination of a number of things to make existence worthwhile. The word itself meant "all."
As of the mid-23rd century, Humans had learned to be delighted with what they were in a way similar to the philosophy of Nome. However, this came centuries after the Vulcans developed the idea.
In 2269, the Excalbian representation of Abraham Lincoln recognized this philosophy, as quoted by Spock, and gave its name, though he wasn't aware how he knew of it. (TOS: "The Savage Curtain")
