“Our first and most pressing problem is how to do away with warfare as a method of solving conflicts between national groups within a society who have different views about how the society is to run.”

“Programmers are isolated. They sit in their cubicle; they don't think about the larger picture. To my mind, a programmer is not an engineer, because an engineer is somebody who starts with a social problem that an organization or a society has and says, "OK, here's this problem that we have- how can we solve it?" The engineer comes up with a clever, cost-effective solution to address that problem, builds it, tests it to make sure it solves the problem. That's engineering.”

“The difference between what we do and what we are capable of doing would suffice to solve most of the world's problems.”

“Social ecology is based on the conviction that nearly all of our present ecological problems originate in deep-seated social problems. It follows, from this view, that these ecological problems cannot be understood, let alone solved, without a careful understanding of our existing society and the irrationalities that dominate it. To make this point more concrete: economic, ethnic, cultural, and gender conflicts, among many others, lie at the core of the most serious ecological dislocations we face today—apart, to be sure, from those that are produced by natural catastrophes.”

“The secret message communicated to most young people today by the society around them is that they are not needed, that the society will run itself quite nicely until they - at some distant point in the future - will take over the reigns. Yet the fact is that the society is not running itself nicely... because the rest of us need all the energy, brains, imagination and talent that young people can bring to bear down on our difficulties. For society to attempt to solve its desperate problems without the full participation of even very young people is imbecile.”

“The further away from something we are, the more we tend to mistrust it, Peter. we dislike the unknown, we reject anything alien to us: people with views that contradict ours, societies that are run along very different lines.”
