TOPIC: Wasn’t Woke Dead…?? I wise man once said: “nobody be complaining if they had casted Terry Crews as Hellen of Troy…” Samuel L. Jackson would be a great option in my humble opinion… TRIGGERED is a discussion group for the young and young at heart, with philosophy as its core but focussed towards recent events, culture, and political philosophy, with a pinch of actual politics. We’ll discuss the selected topic as a group and probably move somewhere else for another drink to talk about anything else. Some of the points we’ll touch on: * Briefly: What is woke? * Netflix, Modern Hollywood and the Modern Audience. * Case Study: Christopher Nolan’s The Odyssey. * Influence of wokeness outside entertainment. So… * Has wokeness actually reached its peak? If so, when did it do so? * Do you go broke if you go woke? * We might have won the war, but why doesn’t it feel like victory? * How to fix this landscape and move forward. Image References: unfortunately we don’t know the genius that brought life to our cover photo for the event…

On Saturday, 27th of June, we’re going to meet and discuss the *The Power of the Powerless* by Václav Havel, an influential book that has become a key text of dissident thought in communist Eastern Europe. Written in 1978, Havel’s book explores how authoritarian systems sustain themselves not only through force, but through conformity, fear, and everyday participation in lies. What does it mean to ‘live within the truth’? Can ordinary people resist oppressive systems, even when they seem powerless? And what forms of responsibility do individuals bear in political life? Although written under late socialism in Czechoslovakia, Havel’s reflections remain strikingly relevant today. How do ideology, bureaucracy, media, and social pressure shape our behaviour? Are modern societies immune to the dynamics Havel describes – or do they simply take different forms? Václav Havel (1936–2011) was a Czech playwright, dissident, political thinker, and statesman. A leading figure of the democratic opposition during communist rule, he later became the last President of Czechoslovakia and the first President of the Czech Republic. *** Anyone is welcome to join! Before the meeting, please read the book (it’s around 100 pages long), think about it, and note any passages you find especially interesting, challenging, or worth discussing. We’ll share our thoughts and interpretations during the meeting. Organizational notes: 📍 Attendance is free ⏳ Spots are limited 🔗 Please register via the app so we know how many people to expect and can reserve a table accordingly
