Some Quotes From Carl Sagan

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

A central lesson of science is that to understand complex issues (or 
even simple ones), we must try to free our minds of dogma and to 
guarantee the freedom to publish, to contradict, and to experiment. 
Arguments from authority are unacceptable. 
Carl Sagan 

It is the responsibility of scientists never to suppress knowledge, 
no matter how awkward that knowledge is, no matter how it may bother 
those in power; we are not smart enough to decide which pieces of 
knowledge are permissible, and which are not. … 
— Carl Sagan 

One of the great commandments of science is, 'Mistrust arguments from 
authority'. (Scientists, being primates, and thus given to dominance 
hierarchies, of course do not always follow this commandment.) 
— Carl Sagan 

The cure for a fallacious argument is a better argument, not the 
suppression of ideas. 
— 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 

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 

[N]o scientist likes to be criticized. ... But you don't reply to 
critics: "Wait a minute, wait a minute; this is a really good idea. 
I'm very fond of it. It's done you no harm. Please don't attack it." 
That's not the way it goes. The hard but just rule is that if the 
ideas don't work, you must throw them away. Don't waste any neurons 
on what doesn't work. Devote those neurons to new ideas that better 
explain the data. Valid criticism is doing you a favor. 
— Carl Sagan 

“...extraordinary claims require extraordinary evidence.” 
Dr. Carl Sagan
