“Kabul is… a thousand tragedies per square mile.”

“We have more televangelists per square mile here in this part of the country than I really care to think about. Maybe somebody out there will figure out how to spray for them.”

“I am twelve thousand miles wiser, twelve thousand miles more resilient, and I have twelve thousand miles more faith in God.”

“Marriage is rarely bliss
But, surely it would be worse
As particles to pelt
At thousands of miles per sec
About a universe
In which a lover's kiss
Would either not be felt
Or break the loved one's neck.”

““… I said about limiting factors. Well, there’s one that you can’t beat. Put steel under fifty thousand pounds per square inch pressure and it starts to flow. The metal used in this machine must have been able to withstand much greater pressure, but there was a limit beyond which it was not safe to go. At twenty miles above the planet’s surface, they had reached that limit. They had reached dead end.” <…>”

“There's no place on earth with more dumb girls per square foot than a college in California.”

“No continent is as small and fragmented as Europe. Only Australia is smaller, yet Europe consists of fifty independent nations (including Turkey and the Caucasus, for reasons explained later). Crowded with nations, it is also crowded with people. Europe's population density is 72.5 people per square kilometer. The European Union's density is 112 people per square kilometer. Asia has 86 people per square kilometer. Europe is crowded and fragmented.”

“We have all the essential elements of a high national career. The idea has been given out at the North, and even in the border States, that we are too small and too weak to maintain a separate nationality. This is a great mistake. In extent of territory we embrace five hundred and sixty-four thousand square miles and upward. This is upward of two hundred thousand square miles more than was included within the limits of the original thirteen States. It is an area of country more than double the territory of France or the Austrian empire. France, in round numbers, has but two hundred and twelve thousand square miles. Austria, in round numbers, has two hundred and forty-eight thousand square miles. Ours is greater than both combined. It is greater than all France, Spain, Portugal, and Great Britain, including England, Ireland, and Scotland, together. In population we have upward of five millions, according to the census of 1860; this includes white and black. The entire population, including white and black, of the original thirteen States, was less than four millions in 1790, and still less in 76, when the independence of our fathers was achieved. If they, with a less population, dared maintain their independence against the greatest power on earth, shall we have any apprehension of maintaining ours now?”

“A cannonball travels only two thousand miles an hour; light travels two hundred thousand miles a second. Such is the superiority of Jesus Christ over Napoleon.”

“The journey of a thousand miles begins with a single step.”
