"So I would," agreed the doctor. "But in our case I couldn't do anything of the kind. Johnny broke over machines that really didn't work. Hoskins broke over phenomena that couldn't be measured nor understood. Ives broke over things that scuttled and crawled. Subjectively real phenomena, all of them. Whatever basic terrors hide in you and in me will come to face us, no matter how improbable they might be. And you want me to tell you what they are. No, skipper. Better leave them in your subconscious, where you've buried them." "I'm not afraid," said the Captain. "Tell me, Paresi! At least I'll know. I'd rather know. I'd so _damn_ much rather know!" "You're sure I can tell you?" "Yes." "I haven't psychoanalyzed you, you know. Some of these things are very hard to--" "You do know, don't you?" "Damn you, yes!" Paresi wet his lips. "All right, then. I may be doing a wrong thing here.... You've cuddled up to the idea that I'm a very astute character who automatically knows about things like this, and it's been a comfort to you. Well, I've got news for you. I didn't figure all these things out. I was told." "Told?" "Yes, told," said Paresi angrily. "Look, this is supposed to be restricted information, but the Exploration Service doesn't rely on individual aptitude tests alone to make up a crew. There's another factor--call it an inaptitude factor. In its simplest terms, it comes to this: that a crew can't work together only if each member is the most efficient at his job. He has to _need_ the others, each one of the others. And the word _need_ predicates _lack_. In other words, none of us is a balanced individual. And the imbalances are chosen to match and blend, so that we will react as a balanced unit. Sure I know Johnny's bugaboos, and Hoskins', and yours. They were all in my indoctrination treatments. I know all your case histories, all your psychic push-buttons." "And yours?" demanded the Captain. "Hoskins, for example," said Paresi. "Happily married, no children. Physically inferior all his life. Repressed desire for pure science which produced more than a smattering of a great many sciences and made him a hell of an engineer. High idealistic quotient; self sacrifice. Look at him playing chess, making of this very real situation a theoretical abstraction ... like leaving a marriage for deep space. "Johnny we know about. Brought up with never failing machines. Still plays with them as if they were toys, and like any imaginative child, turns to his toys for reassurance. He needs to be a hero, hence the stars.... "Ives ... always fat. Learned to be easy-going, learned to laugh _with_ when others were laughing _at_, and bottling up pressures every time it happened. A large appetite. He's here to satisfy it; he's with us so he can eat up the galaxies...." There was a long pause. "Go on," said the Captain. "Who's next? You?"
