More quotes by Carl Sagan
If you wish to make an apple pie from scratch, you must first invent the universe.
Carl Sagan
If you are only skeptical, then no new ideas make it through to you.
Carl Sagan
We are like butterflies who flutter for a day and think it is forever.
Carl Sagan
The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
Carl Sagan
What began in deadly competition has helped us to see that global cooperation is the essential precondition for our survival. Travel is broadening. It's time to hit the road again.
Carl Sagan
Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question?
Carl Sagan
And after we returned to the savannahs and abandoned the trees, did we long for those great graceful leaps and ecstatic moments of weightlessness in the shafts of sunlight of the forest roof?
Carl Sagan
If we're capable of conjuring up terrifying monsters in childhood, why shouldn't some of us, at least on occasion, be able to fantasize something similar, something truly horrifying, a shared delusion, as adults?
Carl Sagan
Science is not only compatible with spirituality it is a profound source of spirituality.
Carl Sagan
Science is more than a body of knowledge. It's a way of thinking: a way of skeptically interrogating the universe.
Carl Sagan
Religions are tough. Either they make no contentions which are subject to disproof or they quickly redesign doctrine after disproof. ... near the core of the religious experience is something remarkably resistant to rational inquiry.
Carl Sagan
The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge it has no in the endeavor of science. We do not know in advance who will discover fundamental insights.
Carl Sagan
If we say that God has always been, why not save a step and conclude that the universe has always been?
Carl Sagan
We are star stuff which has taken its destiny into its own hands. The loom of time and space works the most astonishing transformations of matter.
Carl Sagan
We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.
Carl Sagan
If there is life, then I believe we should do nothing to disturb that life. Mars then, belongs to the Martians, even if they are microbes.
Carl Sagan
I also wish that the Pledge of Allegiance were directed at the Constitution and the Bill of Rights, as it is when the President takes his oath of office, rather than to the flag and the nation
Carl Sagan
We humans look rather different from a tree. Without a doubt we perceive the world differently than a tree does. But down deep, at the molecular heart of life, the trees and we are essentially identical.
Carl Sagan
The gears of poverty, ignorance, hopelessness and low self-esteem interact to create a kind of perpetual failure machine that grinds down dreams from generation to generation. We all bear the cost of keeping it running. Illiteracy is its linchpin.
Carl Sagan
Not all birds can fly. What separates the flyers from the walkers is the ability to take off.
Carl Sagan
