What is good reasoning and what is manipulation? How can manipulation be recognized in the private as well as in the public sphere? What is propaganda and how does it work? In this session, we will analyse some basic concepts of manipulation and countermeasures and discuss the main ideas of the Harvard concept of fair and respectful negotiation. We will then look at basic ideas established by the father of modern propaganda, Edward L. Bernays (1891 -1995) and give some illustrative examples. Finally, we will describe the freedom of Christian thinking, how to break self-censorship, overcome conformity and speak up in public persuasively and effectively.
