“The chance of receiving a signal from a civilization exactly as advanced as we are should be minuscule. If they were even a little behind us, they would lack the technological capability to communicate with us at all. So the most likely signal would come from a civilization much more advanced.”

“It's not technology that limits us. We're the limitation. Our technology is an expression of our intelligence and creativity, so the limitations of our technology are a reflection of our own limitations. We can't fundamentally advance technology until we fundamentally advance ourselves.”

“In the educated class even social life is a series of aptitude tests; we all must perpetually perform in accordance with the shifting norms of propriety, ever advancing signals of cultivation.”

“They must talk to each other directly, Ender, mind to mind. What one thinks, another can also think; what one remembers, another can also re-member. Why would they ever develop language? Why would they ever learn to read and write? How would they know what reading and writing were if they saw them? Or signals? Or numbers? Or anything that we use to communicate? This isn’t just a matter of translating from one language to another. They don’t have a language at all. We used every means we could think of to communicate with them, but they don’t even have the machinery to know we’re signaling. And maybe they’ve been trying to think to us, and they can’t understand why we don’t respond.”

“A god who is capable of sending intelligible signals to millions of people simultaneously, and of receiving messages from all of them simultaneously, cannot be, whatever else he might be, simple. Such Bandwidth!”

“None of us knows the wisdom of the Lord. We do not know in advance exactly how He would get us from where we are to where we need to be, but He does offer us broad outlines in our patriarchal blessings. We encounter many bumps, bends, and forks in the road of life that leads to the eternities.”
