In one of his last public addresses, astronomer Carl Sagan discusses how his wonder about the universe was awakened by the stars and the sun. He continues on issues regarding Science, superstition, religion, faith, education, skepticism, and Humanism.
Sagan describes how science rewards those who disprove ideas, which is the ideological opposite in politics, religion and other social constructs: which reward those who reassure or reinforce existing ideas–which is the fundamental reason why science has progressed so much, while other social constructs have stagnated.
He speaks of the internal corrective mechanism in science: that all scientists acknowledge fallibility of ideas. He says: “be willing to surrender your ideas” meaning criticism and critical thinking is at the core of science.
He also talks about the dangers of pseudo-science, which has a tendency to crowd out genuine science in the popular imagination.
