“We use other people's brains to navigate the world: to acquire skills and practices, and to access knowledge systems of long-dead strangers. We call this 'culture'.”

“First, we cannot overload the human brain. This divinely created brain has fourteen billion cells. If used to the maximum, this human computer inside our heads could contain all the knowledge of humanity from the beginning of the world to the present and still have room left over. Second, not only can we not overload our brain - we also know that our brain retains everything. I often use saying that "The brain acquires everything that we encounter." The difficulty does not come with the input of information, but getting it out. Sometimes we "file" information randomly of little importance, and it confuses us.”

“In that case, on behalf of Earthlife, I urge that, with full knowledge of our limitations, we vastly increase our knowledge of the Solar System and then begin to settle other worlds.”

“Like a magnetized needle floating on a surface of oil, Resistance will unfailingly point to true North - meaning that calling or action it most wants to stop us from doing.We can use this. We can use it as a compass. We can navigate by Resistance, letting it guide us to that calling or action that we must follow before all others.”

“I believe we inherit a great river of knowledge, a flow of patterns coming from many sources. The information that comes from deep in the evolutionary past we call genetics. The information passed along from hundreds of years ago we call culture. The information passed along from decades ago we call family, and the information offered months ago we call education. But it is all information that flows through us. The brain is adapted to the river of knowledge and exists only as a creature in that river. Our thoughts are profoundly molded by this long historic flow, and none of us exists, self-made, in isolation from it.”

“The meeting between ignorance and knowledge, between brutality and culture - it begins in the dignity with which we treat the dead”
