Leonard Nimoy credited as playing...
Mr. Spock
- Captain James T. Kirk: Evaluation of M-5 performance. It'll be necessary for the log.
- Mr. Spock: The ship reacted more rapidly than human control could have maneuvered her. Tactics, deployment of weapons, all indicate an immense sophistication in computer control.
- Captain James T. Kirk: Machine over man, Spock? It was impressive. Might even be practical.
- Mr. Spock: Practical, Captain? Perhaps. But not desirable. Computers make excellent and efficient servants; but I have no wish to serve under them. Captain, a starship also runs on loyalty to one man, and nothing can replace it, or him.
- Dr. McCoy: I don't like it, Jim. A vessel this size cannot be run by one computer.
- Mr. Spock: We're attempting to prove that it can run this ship more efficiently than man.
- Dr. McCoy: Maybe *you're* trying to prove that, Spock; but don't count me in on it.
- Mr. Spock: The most unfortunate lack in current computer programming is that there is nothing available to immediately replace the starship surgeon.
- Wesley: [after M-5's first successful battle drill] Our compliments to the M-5 unit. And regards to Captain Dunsel. Wesley out.
- Dr. McCoy: "Dunsel"? Who the blazes is Captain Dunsel? What does it mean, Jim?
- [Kirk slowly leaves the bridge without another word or looking anyone in the eye]
- Dr. McCoy: Spock. What does it mean?
- Mr. Spock: 'Dunsel', Doctor, is a term used by midshipmen at Starfleet Academy. It refers to a part which serves no useful purpose.
- Mr. Spock: Commodore Wesley is a dedicated commander. I should regret serving aboard the instrument of his death.
- Captain James T. Kirk: The instrument of his death will not be the Enterprise if I can help it.
- Dr. McCoy: Compassion. That's the one thing no machine ever had. Maybe it's the one thing that keeps men ahead of them. Care to debate that, Spock?
- Mr. Spock: No, Doctor. I simply maintain that computers are more efficient than human beings, not better.
- Dr. McCoy: But tell me - which do you prefer to have around?
- Mr. Spock: I presume your question is meant to offer me a choice between machines and human beings; and I believe I have already answered that question.
- Dr. McCoy: I was just trying to make conversation, Spock.
- Mr. Spock: It would be most interesting to impress your memory engrams on a computer, Doctor. The resulting torrential flood of illogic would be most entertaining.
- Mr. Spock: M-5 is leaving itself open to attack. The machine is committing suicide, to atone for the sin of murder.
- Wesley: Have you heard of the M-5 multitronic unit?
- Captain James T. Kirk: That's, uh... Dr. Richard Daystrom's device, isn't it? Tell me about that.
- Mr. Spock: The most ambitious computer complex ever created. Its purpose is to correlate all computer activity aboard a starship, to provide the ultimate in vessel operation and control.
- Wesley: How do you know so much about it, Commander?
- Mr. Spock: I hold an A-7 computer expert classification, Commodore. I'm well acquainted with Dr. Daystrom's theories and discoveries. The basic design of all our ship's computers are Dr. Daystrom's.
- Mr. Spock: Captain, the computer does not judge. It makes logical selections.
- [on Kirk's comment that the difference in recommendation from M-5 was only a matter of judgment]
