More quotes by Carl Sagan
For all I know we may be visited by a different extraterrestrial civilization every second Tuesday, but there's no support for this appealing idea. The extraordinary claims are not supported by extraordinary evidence.
Carl Sagan
The difference between physics and metaphysics is not that the practitioners of one are smarter than the practitioners of the other. The difference is that the metaphysicist has no laboratory.
Carl Sagan
We are not smart enough to decide which pieces of knowledge are permissible and which are not.
Carl Sagan
Modern science has been a voyage into the unknown, with a lesson in humility waiting at every stop. Many passengers would rather have stayed home.
Carl Sagan
Humans are very good at dreaming, although you'd never know it from your television.
Carl Sagan
If the press descended, the science would surely suffer.
Carl Sagan
In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?
Carl Sagan
Indeed the reasoned criticism of a prevailing belief is a service to the proponents of that belief if they are incapable of defending it, they are well advised to abandon it. This self-questioning and error-correcting aspect of the scientific method is its most striking property.
Carl Sagan
Science is a way of thinking much more than it is a body of knowledge.
Carl Sagan
There is today-in a time when old beliefs are withering-a kind of philosophical hunger, a need to know who we are and how we got here. It is an on-going search, often unconscious, for a cosmic perspective for humanity
Carl Sagan
Our passion for learning ... is our tool for survival.
Carl Sagan
We live in a society exquisitely dependent on science and technology and yet have cleverly arranged things so that almost no one understands science and technology.
Carl Sagan
The prediction of nuclear winter is drawn not, of course, from any direct experience with the consequences of global nuclear war, but rather from an investigation of the governing physics.
Carl Sagan
A multitude of aspects of the natural world that were considered miraculous only a few generations ago are now thoroughly understood in terms of physics and chemistry.
Carl Sagan
The method of science, as stodgy and grumpy as it may seem, is far more important than the findings of science.
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
Perhaps the depth of love can be calibrated by the number of different selves that are actively involved in a given relationship.
Carl Sagan
The universe is a pretty big place. If it's just us, seems like an awful waste of space.
Carl Sagan
I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.
Carl Sagan
Science is merely an extremely powerful method of winnowing what's true from what feels good.
Carl Sagan
