A Quote by Carl Sagan

In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it. — © Carl Sagan
In the long run, the aggressive civilizations destroy themselves, almost always. It's their nature. They can't help it.
That complacency and that willingness to give yourself over to a larger power structure is how civilizations destroy themselves. And I just hope people wake up from the slumber they've willed themselves to. Because we're really in a dark place right now.
A technological advance of a major sort almost always is overestimated in the short run for its consequences - and underestimated in the long run.
No one is safe from nature's savagery,not even the innocent. Only beauty is consistent. Gabrielle envisions a time when the Savage Garden will overtake civilizations and destroy it.
We're a part of nature. As we destroy nature, we destroy ourselves. It's a selfish thing to want to protect nature.
This long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again.
I think you try to extrapolate from the early civilizations and cultures of the continent, kind of looking for unique ways they set themselves apart from Western civilizations, and then pursue those avenues technologically and see where that takes you.
Any one who has studied the history of science knows that almost every great step therein has been made by the "anticipation of Nature," that is, by the invention of hypotheses, which, though verifiable, often had very little foundation to start with; and, not unfrequently, in spite of a long career of usefulness, turned out to be wholly erroneous in the long run.
I'm often asked what I think about as I run. Usually the people who ask this have never run long distances themselves. I always ponder the question. What exactly do I think about when I'm running? I don't have a clue.
If we're thinking about old civilizations, those that formed a long time ago and there were stars and planets around long before Earth even existed, then these are going to be towards the center of the galaxy. That is the place to look if you think there are ancient civilizations that have made beacons or some other way of attracting our attention.
Scottie was just a different character than Michael. He was more the soft side. Every once in a while he would explode, but he would help me. Michael on the other end was almost always aggressive.
If we pursue this way, if we are decent, industrious, and honest, if we so loyally and truly fulfill our duty, then it is my conviction that in the future as in the past the Lord God will always help us. In the long run He never leaves decent folk in the lurch. Often He may test them, He may send trials upon them, but in the long run He always lets His sun shine upon them once more and at the end He gives them His blessing.
I think we're simply going to run out of Nature before we have a chance to destroy it.
God, to prevent all escape, hath sown the seeds of death in our very constitution and nature, so that we can as soon run from ourselves, as run from death. We need no feller to come with a hand of violence and hew us down; there is in the tree a worm, which grows out of its own substance, that will destroy it; so in us, those infirmities of nature that will bring us down to the dust.
Most people tell themselves these excuses - I've always been this way, how can I possibly change, this is my nature, I can't help it - that are just memes
By nature, you're aggressive, if you're a fighter, so you deal with things in an aggressive way.
A fad or heresy is the exaltation of something which even if true, is secondary or temporary in its nature against those things which are essential and eternal, those things which always prove themselves true in the long run. In short, it is the setting up of the mood against the mind.
