Quotes About Truth

There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.
~ Carl Sagan
Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe.
~ Carl Sagan
At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense.
~ 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

~ Carl Sagan
Better the hard truth, I say, than the comforting fantasy.
~ Carl Sagan
There are many hypotheses in science which are wrong. That's perfectly all right: it's the aperture to finding out what's right. Science is a self-correcting process.

The major religions on the Earth contradict each other left and right. You can't all be correct. And what if all of you are wrong? It's a possibility, you know. You must care about the truth, right? Well, the way to winnow through all the differing contentions is to be skeptical. I'm not any more skeptical about your religious beliefs than I am about every new scientific idea I hear about. But in my line of work, they're called hypotheses, not inspiration and not revelation.
~ Carl Sagan

intellectual capacity is no guarantee against being dead wrong.
~ Carl Sagan
Finding the occasional straw of truth awash in a great ocean of confusion and bamboozle requires intelligence, vigilance, dedication, and courage. But if we don't practice these tough habits of thought, we cannot hope to solve the truly serious problems that face us --- and we risk becoming a nation of suckers, up for grabs by the next charlatan who comes along.
~ Carl Sagan
It goes with a courageous intent to greet the universe as it really is, not to foist our emotional predispositions on it but to courageously accept what our explorations tell us.

I maintain there is much more wonder in science than in pseudoscience. And in addition, to whatever measure this term has any meaning, science has the additional virtue, and it is not an inconsiderable one, of being true.
~ Carl Sagan
In good speaking, should not the mind of the speaker know the truth of the matter about which he is to speak?
~ Carl Sagan
The more we want it to be true, the more careful we have to be. No witness's say-so is good enough. People make mistakes. People play practical jokes. People stretch the truth for money or attention or fame. People occasionally misunderstand what they're seeing. People sometimes even see things that aren't there.
~ Carl Sagan
Science is an ongoing process. It never ends. There is no single ultimate truth to be achieved, after which all the scientists can retire.
~ Carl Sagan
There is no single ultimate truth to be achieved, after which all the scientists can retire. And because this is so, the world is far more interesting, both
