It seems madness to say, 'We're worried that they're going to become addicted to marijuana' -- there's no evidence whatever that it's an addictive drug, but even if it were, these people are dying, what are we saving them from?

More quotes by Carl Sagan
Extraordinary claim requires extraordinary proof.
Carl Sagan
Man is the matter of the cosmos, contemplating itself.
Carl Sagan
He sought a way to preserve the past. John Hershel was one of the founders of a new form of time travel.... a means to capture light and memories. He actually coined a word for it... photography. When you think about it, photography is a form of time travel. This man is staring at us from across the centuries, a ghost preserved by light.
Carl Sagan
There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.
Carl Sagan
A tiny blue dot set in a sunbeam. Here it is. That's where we live. That's home. We humans are one species and this is our world. It is our responsibility to cherish it. Of all the worlds in our solar system, the only one so far as we know, graced by life.
Carl Sagan
Thus the recent rapid evolution of human intelligence is not only the cause of but also the only conceivable solution to the many serious problems that beset us.
Carl Sagan
It is clear that the nations of the world now can only rise and fall together. It is not a question of one nation winning at the expense of another. We must all help one another or all perish together.
Carl Sagan
A single message from space will show that it is possible to live through technological adolescence. . . . It is possible that the future of human civilization depends on the receipt of interstellar messages.
Carl Sagan
Science is merely an extremely powerful method of winnowing what's true from what feels good.
Carl Sagan
It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.
Carl Sagan
The method of science is tried and true. It is not perfect, it's just the best we have. And to abandon it, with its skeptical protocols, is the pathway to a dark age.
Carl Sagan
Sailors on a becalmed sea, we sense the stirring of a breeze.
Carl Sagan
Extraordinary claims demand extraordinary evidence
Carl Sagan
Somewhere, something incredible is waiting to be known.
Carl Sagan
If we do not speak for Earth, who will? If we are not committed to our own survival, who will be?
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
Arguments from authority carry little weight – authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities at most, there are experts.
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
The well-meaning contention that all ideas have equal merit seems to me little different from the disastrous contention that no ideas have any merit.
Carl Sagan
An atheist has to know a lot more than I know. An atheist is someone who knows there is no god. By some definitions atheism is very stupid.
Carl Sagan
