**THE STRUCTURE of THE EVENT:**
* I will post the event on Saturday/Sunday evening for the following Saturday.
* I send out a reminder to everyone on Friday.
* There is sometimes a waiting list.
* In case RSVP is closed (once there are 10-15 people on the waiting list), I might reopen it on Friday, depending on the number of cancellations in the meantime.
* **For everyone on the waiting,** please check your status and messages on Friday evening the latest. I message everyone on the waiting list on Friday.
* **Please, move to "not going" AS SOON AS you know that you can't come anymore, that includes everyone who is on the waiting list.**
**IMPORTANT:**
* **Please, be respectful towards each other during the event. (And after ;))**
* When you register yourself, be careful not to register accidentally a +1 guest (unless you bring a guest). It happens very often.
* If you have any questions then, message me.
***
**A MESSAGE FOR NEWCOMERS:**
*In the three years of hosting this coffee group, I have met many people who struggle with anxieties when coming to an event for the first time. Sometimes, it took them more than one attempt before being able to join.*
*Occasionally, people reach out to me before the event, and I have always been grateful for that as it offers the opportunity to communicate with each other and to find the best and most gentle way for that person to join the group.*
*I would like to encourage everyone who struggles with this to contact me before. It would really be too bad if you can't join us, as it mostly gets better the second or third time you come.*
*In addition to that, if you arrive and notice any signs of nervousness or fear, you can always let me know right then.*
**THANK YOU AND SEE YOU ALL ON Saturday!**

Silent Walk in the Forêt de Soignes
We will be walking through the forest for a little over 1 1/2 hours, silently, just noticing the world around us and inside us. The idea is to experience the magic of a different type of walking, The invitation is to slow down and notice what is going on inside you and around you.
Very often people experience a closer connection with nature and with self, with sometimes surprising insights.
*Please make sure you are fit enough to go the 4.5 km distance. We will be walking slowly, but we will not take any breaks.*
We will be meeting at the Hermann Debroux Metro at **14h**. (Exit straight ahead after leaving the platform--on the Loxam side).
If you RSVP as coming, please be on time. We will be starting our walk from there 5 min. after the hour sharp.
There is the renovated Maison de Prieur at the exit of the forest where we could gather for a drink or a meal after our walk, depending on what you feel like.
Looking forward to an inward adventure? Come and join us on **Saturday, April 25, at 14h**
My phone number is 0472 92 11 76, in case you need to communicate with me.
The unit and the whole: how to construct your poetry pamphlet
[This is a paid event and sign-up via the website is obligatory](https://www.wordcraft-collective.eu/courses/the-unit-and-the-whole%3A-how-to-construct-your-poetry-pamphlet).
After running this very successful workshop in autumn 2025 we are running it again for those who might have missed out the first time.
In this workshop we will explore how to bring together a group of poems to produce a pamphlet or book. We will explore the notion of the poetry pamphlet versus full collection in terms of the function and purpose of each and how they operate. We will think about structuring a body of work, how to sequence poems and what the organising principles might be. How does the placing of poems together change or enhance the poem? How do we build on and around key themes? We will look at examples of published pamphlets and books to consider how and why authors have brought poems together in the way they have, identifying the choices and opportunities available to poets. Participants are encouraged to bring along their own poems or projects in progress to discuss with others in the group.
This workshop is run by poet Paul Stephenson, who has published three poetry pamphlets and one collection.

Groenendaal Spring circuit
Come and join this 15+ km hike in the Forest de Soigne.
The walk will give us a true (!) forest spring experience 😊 with young leafs, anemone and hyacinths. 💮🪻
Participants can use either bicycle, car or train to get to the assembly point
Parking PLEK Restaurant & Coworking, Duboislaan 1, 1560 Hoeilaart.
A train will stop at 10:22 at station Groenendaal, from where it takes 15 minutes to the car park.
This train stops at many stations in Brussels, i.e. Central 09:52, Schuman 10:06, Bosvoorde 10:18.
We will leave at 10:45 from the car park. The circuit allows us to have a nice drink on the terrace before returning to our transport.
There's only one train per hour back to Brussels, so either 14:32 or 15:32.
During the hike we will stop for a bring-your-own-lunch and there is the promise of passing by some undergrowth beautifully covered by hyacinths. and that is an understatement. 😊
Come along for this talk and walk!

You’re welcome to come alone or with guests, meet new people, and just enjoy the atmosphere if that’s what you need.

Picnic & Games 🌳🧺🏸 🎲 (TBC🌤️)
What's up Friends! 👋
If the weather gods feel generous 🌤️, we’re going full park mode: picnic 🧺🌳, games, laughs… and a touch of chaos ✨

📍Where
Park Cinquantenaire, Tour de Tournai 🏰 (that little castle-looking thingy in the park).
Can’t find us? 🤷♀️ Just ping me here.

We’ll break into small groups depending on the vibe: games, chats, sports.
⏱️ Timing
We kick off at 14:00. Stay as long as you like.
Joining later? Just drop a message in the chat in case we decide to move 😊.
🎲🏸 Games
All games are welcome in the park - boards, cards, balls, random stuff! I’ll have a few with me, but feel free to add your own favorites too.
🚦On the waitlist but really want to join? Or got any questions? Just DM me.
📢 Extra info might drop in the group chat or via DM 💬. Check your messages 👀 the day before so you don't miss anything critical 🙄.
🐈⬛ The Friends Code:
👉 Games we play = group decision
👉 Smaller groups = cozier vibes
👉 Got a favorite game? Suggest it or show up with it
👉 Can't make it? Cancel on time so someone on the waitlist can grab your spot
👉 If you’re on the waitlist, showing up is at your own risk 😄
See you there, folks 😉
Deep Conversation - Question Chosen in Session
Welcome to our weekly event in the upstairs room of The Sister Café, rue Chair et Pain 3, one block from the Grand Place. Please get there early enough to order your drink at the bar first. Thank you!
After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations.
Past questions have been wide and not confined to academic philosophy:
What is a genuine friend?
Is social media turning us into emotional zombies?
Do we lose some of the experience of things by defining them?
Are we driven by sex?
Is loneliness a personal failure?
Is morality relative?
**Crucially, be kind and respectful and generous** in your disagreements; remember how much you personally enjoy someone else proving you wrong before celebrating your cutting counterexamples.
Grief workshop
Have you recently lost a loved one and struggling with difficult emotions?
Join Vanessa Goodman, clinical psychologist, in this two-part workshop on grief.
**Program**: sharing circle, journaling, guided meditations, rituals and creative art-work.

Duty vs. Results: What Makes an Action Moral?
When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches.
* **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason.
* **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes.
## Discussion Questions
1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie.
2. **Can good intentions rescue a bad outcome?**
3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome?
4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend?
5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles?
6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way?
7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time?
8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?
