Knowing a great deal is not the same as being smart; intelligence is not information alone but also judgment, the manner in which information is collected and used

Skeptical scrutiny is the means, in both science and religion, by which deep insights can be winnowed from deep nonsense

If we long to believe that the stars rise and set for us, that we are the reason there is a Universe, does science do us a disservice in deflating our conceits?

It seems to me what is called for is an exquisite balance between two conflicting needs: the most skeptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas. If you are only skeptical, then no new ideas make it through to you. On the other hand, if you are open to the point of gullibility and have not an ounce of skeptical sense in you, then you cannot distinguish useful ideas from the worthless ones.

You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe

Vi är som fjärilar som flaxar omkring för en dag och tror det är för evigt.

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.

Skeptical scrutiny is the means, in both science and religion, by which deep thoughts can be winnowed from deep nonsense.

Imagination will often carry us to worlds that never were. But without it we go nowhere.

There are many hypotheses in science which are wrong. That's perfectly all right; they're the aperture to finding out what's right. Science is a self-correcting process. To be accepted, new ideas must survive the most rigorous standards of evidence and scrutiny.

Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.

I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence.

Bättre att tända ett ljus än att förbanna mörkret.

It's better to light a candle then to curse the darkness.

Extraordinary claims require extraordinary evidence

Vi är stjärnstoft.
