QotD: Skepticism

[liveonearth]

What skeptical thinking boils down to is the means to construct, and to understand, a reasoned argument and, especially important, to recognize a fallacious or fraudulent argument. The question is not whether we like the conclusion that emerges out of a train of reasoning, but whether the conclusion that emerges out of a train follows from the premise of starting point and whether that premise is true.
--Carl Sagan in his Baloney Detection Kit
