“An audience that is unwilling to suspend its own presuppositions and biases while considering an opposed (or even unopposed) viewpoint not only frustrates the function of extended argument but effectively denies its own beliefs a rational basis.”

“‎People have presuppositions... By 'presuppositions' we mean the basic way that an individual looks at life- his worldview. The grid through which he sees the world. Presuppositions rest upon that which a person considers to be the truth of what exists. A person's presuppositions provide the basis for their values- and therefore the basis for their decisions.”

“To hold that the Qur’ān believes in an absolute determinism of human behavior, denying free choice on man's part, is not only to deny almost the entire content of theQu r’ān, but to undercut its very basis: the Qur’ān by its own claim is an invitation to man to come to the right path (hudan lil-nās).”

“An artist is someone who can hold two opposing viewpoints and still remain fully functional.”

“The Tea Party is a fitting representation of our era of no-debate, politically correct politics, where each political side has its own media, and opposing views are almost never given a fair hearing. Conservatives listen only to conservatives, and liberals listen only to liberals. People are spared the inconvenience of facts that don’t fit their beliefs and the unpleasantness of seriously considering a point of view other than their own.”

“if the audience is receptive to changing a habit, the communication should include only favorable points, but if the audience is not inclined to accept the message, the communication should discuss both sides of the issue (pointing out its risk while acknowledging and rebutting its pleasurable effects).”
