Aviation, Geography, and Race (1939)
Context: Air power is new to all our countries. It brings advantages to some and weakens others; it calls for readjustment everywhere.
If only there were some way to measure the changing character of men, some yardstick to reapportion influence among the nations, some way to demonstrate in peace the strength of arms in war. But with all of its dimensions, its clocks, and weights, and figures, science fails us when we ask a measure for the rights of men. They cannot be judged by numbers, by distance, weight, or time; or by counting heads without a thought of what may lie within. Those intangible qualities of character, such as courage, faith, and skill, evade all systems, slip through the bars of every cage. They can be recognized, but not measured.

Context: The whole thing never happened and I can prove it — now. But Ira De Kalb made me wait a billion years to write the story.
So we start with a paradox. But the strangest thing of all is that there are no real paradoxes involved, not one. This is a record of logic. Not human logic, of course, not the logic of this time or this space.

Context: At some point, I stopped and made the following note to myself: I have never finished a story. I'm beginning to see that now. I don't think that there's ever a point where a story or novel is just exactly right. There are only finer and lesser degrees of refinement, and even those are probably subjective. You might think it's perfect for a time, but read it a year or five years later, and you'll see you were mistaken. There's always something I can make better, every time I read one of my stories. Usually there are dozens of somethings. And I once thought this wasn't true, that a story reached a certain point and beyond that point you were only changing things, making them different, not making them better. Indeed, I thought, beyond a point, you risk screwing it all up. I don't think that anymore. You risk screwing it all up right from the start, and no story is ever as perfect as it can be. Perfection is always one or two polishes away from the writer.

But one story reflects his desire clearest. The 'Flying Sikh' remembers, Rohit, Brijnath, 30 July 2008, 12 July 2013, BBC News http://news.bbc.co.uk/1/hi/world/south_asia/7532626.stm,
