“With four-to-one odds against us, our ability to leave the encounter without serious damage becomes seriously impaired." "Spock," McCoy said gently, "your bedside manner is flawless. You mean, we're all going to be blown to hell." Spock hesitated, then nodded.”

“One of the creatures in the front circle shook itself all over and, still shaking, moved very, very slowly toward Spock. He didn't move a muscle. The creature put out a long slender pseudopod, gleaming in the sunshine like suddenly blown glass, and poked Spock's boot with it. Then it made the scratchy sound again, more laughter, and said a word: "Gotcha!" It jumped back into place. All the other creatures began to echo the scratch-laughter. Spock looked around him in mild bemusement. "Captain," he said, "I suspect we have found a kindergarten...”

“What, in all very seriousness, the hell was going on?”

“Why in fact should one tell the truth? What obliges us to do it? And why do we consider telling the truth to be a virtue? Imagine that you meet a madman, who claims that he is a fish and that we are all fish. Are you going to argue with him? Are you going to undress in front of him and show him that you don't have fins? Are you going to say to his face what you think?...If you told him the whole truth and nothing but the truth, only what you thought, you would enter into a serious conversation with a madman and you yourself would become mad. And it is the same way with the world that surrounds us. If I obstinately told the truth to its face, it would mean that I was taking it seriously. And to take seriously something so unserious means to lose all one's own seriousness. I have to lie, if I don't want to take madmen seriously and become a madman myself.”

“You're his lobster. Or swan, Or penguin. The Spock to his Kirk”

“It can only be our familiarity with soap bubbles from our earliest recollections, causing us to accept their existence as a matter of course, that prevents most of us from being seriously puzzled as to why they can be blown at all.”
