A quote from the last story "Sucker Bait", from Cimon, an astrophysicist:
"It's my opinion that information outside a professional man's specialty is useless and a waste of psycho-potential"I know people like who think like that. I'd rather be well rounded myself. The story also argues for knowing a bit about everything rather than being so narrowly focused.
These stories are from the 50's so my biggest complaint is a product of the time. There are hardly any women in these. "The Martian Way" has one character with a shrew for a wife and that's the only female. "Sucker Bait" has no women at all, "Youth"'s only female is the housekeeper. I wish older sci-fi was a bit more balanced. Overall though i liked the book and give it a 5.
