As a former teacher, I repeatedly told my students, “The main purpose of education is the search for truth.” Belief alone will not make something true if in fact it isn’t. For example, at one time people “knew” the earth was flat. It was a belief that had been held passionately for years.
As in science, truth in politics matters but must be searched for. So the challenge we should all be willing to face is … what do I believe politically, why and is it true?
