Carl Sagan did what few before him did: he brought science into the living rooms and minds of average people all over the world. He has inspired a new generation of scientists to carry on his work in classrooms, labs, planetariums and observatories. His science wasn’t always about the cheerful nature of learning something new about the cosmos. In his last interview while alive, Sagan provides us with a warning.
“Science is more than a body of knowledge. It is a way of thinking; a way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then, we are up for grabs for the next charlatan (political or religious) who comes rambling along.”
