This is the view of Carl Sagan, who discusses anti-science and addresses four of the most common criticisms that scientists face: science is evil, science is too narrow, science changes too fast, and we might be better off not knowing. Let’s take a look at how Sagan explains anti-science and unpacks these four criticisms.
Where does knowledge come from? Why does Deutsch believe knowledge comes from guessing? The book The Beginning of Infinity says that knowledge is infinite and people are responsible for finding it.
