Captain Spock has sadly indeed gone to explore the final frontier (Leonard Simon Nimoy - March 26, 1931 - February 27, 2015). At 83 Terran years of age, Captain Spock, now Ambassador Spock, finally succumbed to end-stage chronic obstructive pulmonary disease. He is survived by his wife, Susan, and his two children: Adam and Julie. Our thoughts and prayers are with his family.
We will always remember him as one of the best - if not the best - Captain of the Enterprise.
We're consumed with grief right now, but even with his death find ourselves comforted by Captain Spock's words from Wrath of Khan:
Spock: "Do not grieve, admiral. It is logical. The needs of the many outweigh ..."
Kirk: "the needs of the few,"
Spock: "Or the one ..." I never took the Kobayashi Maru test, until now... What do you think of my solution?"
Spock: ""I have been and always shall be your friend. Live long and prosper."
His soul was indeed the most "human."
