A Bit Less Bloody (The Immunity Syndrome)

[Sickbay] 
(Spock is on a biobed, being scanned.) 
SPOCK: I assure you, Doctor, I am quite all right. The pain was momentary. It passed quickly. 
MCCOY: All of my instruments seem to agree with you if I can trust these crazy Vulcan readings. Spock, how can you be so sure the lntrepid was destroyed? 
(Spock gets off the bed.) 
SPOCK: I sensed it die. 
MCCOY: But I thought you had to be in physical contact with a subject before 
SPOCK: Doctor, even I, a half-Vulcan, could hear the death scream of four hundred Vulcan minds crying out over the distance between us. 
MCCOY: Not even a Vulcan could feel a starship die. 
SPOCK: Call it a deep understanding of the way things happen to Vulcans, but I know not a person, not even the computers on board the Intrepid, knew what was killing them or would have understood it had they known. 
MCCOY: But four hundred Vulcans? 
SPOCK: I've noticed that about your people, Doctor. You find it easier to understand the death of one than the death of a million. You speak about the objective hardness of the Vulcan heart, yet how little room there seems to be in yours. 
MCCOY: Suffer the death of thy neighbour, eh, Spock? You wouldn't wish that on us, would you? 
SPOCK: It might have rendered your history a bit less bloody.
