This lecture by philosopher Bruce Little discusses how beliefs are formed. He discusses the nature of beliefs, how they form and their relationship to truth, the notion of persuasion, and how beliefs might be changed. All of this is aimed at a better understanding of what is involved in Christian witnessing and apologetics, with examples from the Bible. Another great audio from bethinking.org.
