Practical Philosophy Meetup - Copenhagen 🇩🇰
Practical Philosophy Meetup - Copenhagen 🇩🇰
**🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 **📓 HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 19:00-19:15 - People arrive and chat, get to know each other before the ‘official' start. * 19:15-19:25 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 19:25-20:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 20:45-21:00 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo. * 21:00 - The official meeting is over but it’s a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other. **🧧PRICING?** Practical Philosophy Club is FREE to attend! We just ask that if we are meeting in a café, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though! **💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** 🗣 “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * ​What will we talk about? What's the topic? ​The topic for the week is shared every Sunday in the Whatsapp group. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX). * Do I need to study or read anything to attend? No preparation is necessary. This isn’t a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it, but it's not required. * Is there a specific philosophy that Practical Philosophy is focused on? The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * Is it mostly men that attend? Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * Can I come alone? Of course you can, we encourage it :) * Can I be late? Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation. * Where do you meet? The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/). 🤝**POLICY** To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group. Practical Philosophy reserves the right to enforce this policy at its discretion to maintain a safe and respectful environment. **PRACTICAL PHILOSOPHY - Making Philosophy Available To All. ✨** Practical Philosophy hosts weekly, in-person meetups in 25+ countries, including Canada, Spain, Japan, Mexico and many more! 🗺️ \*\*\* Join our [Whatsapp group](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX) 👈 Follow us on [Instagram](https://www.instagram.com/practicalphilosophyclub/?hl=en) 👈 Our [website](https://www.practicalphilosophy.club/) 👈
Silvers Dinners Wednesdays
Silvers Dinners Wednesdays
Tickets here: [www.TheSilvers.dk](www.thesilvers.dk) Here in Copenhagen we have started a movement of weekly dinners (on a Wednesday) hosted by the senior generation in their own homes.

Every Wednesday there is dinner hosted by a different Silver (senior host) who will open their front door, welcome a group of 5-8 people into their home, and share their stories, knowledge, and connections across the table over a themed evening. Each host chooses their own theme and it is the aim to pass on their hard-earned knowledge.

Let's meet and talk books
Hi everyone! Let's gather and share our reading. As usual, we will meet at the fourth floor of the Central Library as it has good facilities for book clubs and it is also free to use. No extra cafe money to spend. Idea is to meet and connect over books. Each participant present 1-2 books they would like to recommend or just talk about, and then we'll see where conversation leads us. Again, there is no limitation to genre or type of book you are reading. The point is that we are free to read whatever we want and then share those reading experiences, so remember to be respectful to each other. I hope to see as many of you as possible. :)

Time for improv fun! ... followed by a pub visit ;)
Time for improv fun! ... followed by a pub visit ;)
Welcome for some fun improv games together :) About us: We are a bunch of people of all ages and backgrounds, gathering to share the common passion for improv. Improvisation, or Improv for short, is a form of live theatre in which the story, characters and scenes are without a script and made up in the moment, completely different every time. The actors are acting, directing themselves, writing the plot and interacting with each other all at the same time without previous planning. Improvisation can help you with your social and business skills by training your mind to think quickly and react to unexpected situations. In Improvisation, there are no lines to memorize and you play off other creatively challenged fun-loving, global-minded people who loves laughing at themselves. It’s a great way to socialize and make new friends. It’s a welcoming atmosphere, we want you to join in the fun, whether you are a complete beginner or an experienced improviser – come and lets enjoy together! We usually start with some warm-ups that help us relax, listen and focus. Then we move on to doing different kinds of short scene fun games with each other, making characters, stories and our small worlds. In improv mistakes are welcome and you will have goooood times! We charge 50 kr in advance in order to cover our expenses. Swish is king! See you very soon ;) Please come only if you are in good health! P.S. You can also follow us on Facebook: https://www.facebook.com/themiip
Big Scientific Questions 2026. Quantum Reality, Free Will, Consciousness + MORE!
Big Scientific Questions 2026. Quantum Reality, Free Will, Consciousness + MORE!
**“Scientific Questions 2026 (!) — Free Will, Quantum Reality, and What We Still Don’t Know”** Mind, Matter, Uncertainty, and the Limits of Explanation Despite all our progress, some of the most fundamental questions remain wide open. As science advances in neuroscience, physics, and AI, old mysteries return in sharper form: Are we truly free? What is reality at the quantum level? And are there limits to what science can ever explain? This isn’t a popular science lecture or a math-heavy session. It’s a philosophical exploration of science at its edges—where evidence runs thin and interpretation matters. *** **Topics we’ll touch on:** * Free will: illusion, emergence, or something real? * Neuroscience and determinism: are “choices” made before we know them? * Quantum interpretations: many worlds, collapse, hidden variables, or something stranger? * Does quantum uncertainty leave room for freedom—or change nothing? * Can science explain consciousness—or just correlate it? * Are there questions science cannot answer in principle? * And finally… how should we live if reality is stranger—and less certain—than we thought? Casual discussion. No physics or neuroscience background required—just curiosity and a tolerance for uncertainty. Whether you lean deterministic, mystical, skeptical, or undecided—you’re not alone. Let’s explore the unanswered questions—and what they mean for how we understand ourselves.

[Columbus library link to book](https://cml.bibliocommons.com/v2/record/S105C3351321) Location: The Goat River South 219 S High St, Columbus, OH 43215 Street parking is free on Sundays [Menu](https://static1.squarespace.com/static/686d3ed16745133042482c5f/t/68ff654dbb03b96875430bde/1761568077220/all_brunch-20250311.pdf) Book summary: On a hot day in Bethlehem, a twelve-year-old Palestinian-American girl is yelled at by a group of men outside the Church of the Nativity. She has exposed her legs in a biblical city, an act they deem forbidden, and their judgement will echo on through her adolescence. When our narrator finally admits to her mother that she is queer, her mother's response only intensifies a sense of shame: 'You exist too much,' she tells her daughter. Told in vignettes that flash between the U.S. and the Middle East--from New York to Jordan, Lebanon, and Palestine--Zaina Arafat's debut novel traces her protagonist's progress from blushing teen to sought-after DJ and aspiring writer.

Drunken Philosophy: Are you really who you think you are? What is the "self"?
Drunken Philosophy: Are you really who you think you are? What is the "self"?
I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes: Imagine a thought experiment that merges two classic puzzles: > You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with? ### Questions to Wrestle With * If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt? * Could there be a "self" without continuity of experience — even moment to moment, while you sleep? On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement? I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!
