Practical Philosophy Meetup - Barcelona 🇪🇸
**🏛️ 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/LAtygOTKzmf1SnQKzJl68Z), along with jump-off points to get the conversation going.
When groups get bigger than 6-8 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:
* 19:30-19:45 - People arrive and chat, get to know each other before the official start.
* 19:45-19:55 - 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.
* 19:55-21:15 - 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.
* 21:15-21:30 - 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.
* 21:30 - 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! At the Barcelona group, we often meet in a friends house. In this case, we ask that everyone bring a snack or a drink to share!
**💛 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/LAtygOTKzmf1SnQKzJl68Z).
* **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/LAtygOTKzmf1SnQKzJl68Z) 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 CLUB - Philosophy, everywhere. ✨**
We started in Practical Philosophy back in 2021 and there are now 20+ chapters in over 15 countries, including Canada, Spain, Japan, Mexico and many more! 🗺️

!ENGLISH! MONDAY DOUBLE SESSION / CAFE - Philosophy Meetup: 19:30h - 21h
Hi and welcome to our next Socrates Café philosophy meetup!
Do you have a hunger for deeper understanding of yourself and the world? Do you value deep, honest and respectful dialogue?
If yes, then this meetup will be very interesting for you.
• WHAT IS A MEETUP ABOUT?
We ask, answer and discuss questions and ideas to stimulate critical thinking and to widen our perspectives with new concepts and thoughts.
The main purpose of these meetups is to enrich ourselves with the perspectives of others, not to convince others about our own perspectives.
Our meetups are about our own philosophies of life and not necessarily what the great philosophers and academics have said or written. It is not a debating club or a platform for proselytizing. Instead, we place the emphasis on questioning, open mindedness and challenging our own assumptions while listening to and respecting the views shared by others.
A Socrates Café meetup is considered a success when participants leave a discussion with many more questions than they had at the beginning.
• WHAT TOPIC IS DISCUSSED AT THE MEETUP?
Participants suggest topics at the beginning of each meeting. We then vote and choose that event's most popular topic for discussion. No academic training in philosophy necessary; just enthusiasm for exchanging ideas and points of view.
Some examples of subjects chosen on previous meetups:
* What ideals are worth dying for?
* Why are we never satisfied?
* Why is it that human beings know that the society is going wrong, leaders are well informed about it and things continue as is?
* Is identity necessary?
* How can it be that people in democratic societies are so obsessed with power? (Desire to be different, better, stronger than others)
* What is friendship?
• WHO PARTICIPATES AT THIS MEETUP?
Anybody is more than welcome to join our meetups. Our events gather people from different backgrounds, different cultures, while no philosophical background is mandatory.
Our usual participants are people that have a hunger for deeper understanding of themselves and the world. People that value deep, honest and respectful dialogue.
The inspiration for Socrates Cafe originates with the book of the same name, written by the philosopher Christopher Phillips. (Socrates Cafe: A Fresh Taste of Philosophy, 2002). Phillips felt that the Socratic method of dialogue and discussion should be practiced not just in academic settings, but among everyday people interested in examining deep questions together. Hundreds of Socrates Cafe groups now exist around the world.

Challenging the UX Mantras
**UX Salon** is thrilled to welcome you to a special event in collaboration with **[Masters in Design for Responsible AI](https://ai.elisava.net/master/design-responsible-ai/)** hosted at the beautiful auditorium at **[Elisava](https://www.elisava.net).**
**Speaker**
In this talk by **[Irene Pereyra](https://www.linkedin.com/in/irenepereyra/)**, a heretic’s stance is taken on the sacred mantras of UX such as “Good UX is simple,” “Good UX is universal,” and “Good UX is intuitive,” challenging them one by one. Through client and personal projects, the argument is made that good UX design is neither universal nor timeless, but situational and shaped by the context of the here and now. The audience is invited to reconsider what “good” truly means in digital design today.
**Irene Pereyra** is the co-founder of the independent design studio Anton & Irene and the author of Universal Principles of UX (Quarto, 2023), with a second book, The Accessible Design Reference & Specification Book, forthcoming in summer 2026. She is also a member of Alliance Graphique Internationale (AGI).
Irene also works at the intersection of design and policy with the Danish think tank 21st Europe, where she contributes to speculative design Blueprints exploring how Europe is rethinking policy, technology, and design. Her work focuses on making complex systems understandable, human, and future-focused.
**Hosts**
**[Iris Latour](https://www.linkedin.com/in/irisjanelatour/), Director of Research @ [THEFT studio](https://theft.studio)** is a UX research leader working at the intersection of AI, product strategy, and responsible innovation. She is also a student in the MDRAI program, focusing on ethics, systems thinking, and the long-term impact of AI on people and organizations.
**[Andres Colmenares](https://www.linkedin.com/in/andrescolmenares/), Director of [MDRAI](https://ai.elisava.net/master/design-responsible-ai/) @ Elisava** is a strategist and creative foresight consultant who has built learning programs from concept to reality at leading design schools and curated gatherings that bring creative communities together. He works at the intersection of futures thinking, strategic design and responsible tech, focusing on collaborative learning, critical thinking and understanding the socio-ecological impacts of AI systems and digital technologies.
**[Master in Design for Responsible AI](https://ai.elisava.net/master/design-responsible-ai/)** by **[Elisava](https://www.elisava.net)** is a pioneering blended-learning program, created in collaboration with [IAM](https://iam-internet.com/), for future leaders of responsible tech looking to develop the critical skills, knowledge and networks needed to design, implement and govern AI systems in ethical, responsible and creative ways.

Fresk Jam
**The Monthly Fresk Jam**
The Fresk Jam is a spin-off of our classic ***Culture Jam***. It is a monthly get together where different workshops around sustainability and climate change are held simultaneously.
These events by ***[Apocapoc BCN](https://www.apocapocbcn.com/?public&)***[ ](https://www.apocapocbcn.com/?public&) are hosted in our **Nest City Lab**.
We strongly believe that to be efficient and healthy at dealing with the current environmental and social crisis, we need to equip ourselves with tools and knowledge that help us to be empowered and to cultivate our "active hope". The ***Culture Jam*** series aims to do just that.
To attend to the workshops, please:

Les ateliers de l'espoir
Qu’est-ce que le fascisme ? Qu'est-ce qu'une démocratie ? Que pouvons nous faire pour la défendre face à la montée du fascisme ?
L'espoir est possible ! De nombreuses luttes historiques ont prouvé que rien n'était inéluctable. De nombreuses structures montrent aujourd'hui la voie d'un renouveau démocratique.
Les Ateliers de l’espoir sont des ateliers d’intelligence collective de 3h, pour prendre du recul, et surtout pour aider à identifier des réponses pertinentes et à la hauteur des enjeux.

**🔹 Circular economy workshop with Alexandra (ENG)**
Based on scientific data and inspired by the **Climate Fresk**, this engaging 3-hour workshop helps you grasp the limits of our **linear economy** (take-make-waste) and explore the opportunities of the **circular economy**—a model that designs out waste and keeps resources in use for longer.
Through teamwork and discussion, you will connect the dots between environmental issues, business models, and everyday life, leaving with **concrete actions** to reduce your footprint.
Whether you're a complete beginner or already familiar with sustainability, this workshop is for everyone! Companies, schools, and communities can also benefit—contact us for dedicated sessions.

Why does 2 + 2 = 4?
We begin with a question that seems almost too obvious to ask: is 2+2=4 really true?
In everyday life it feels immediate—two apples and two apples make four apples. But mathematics asks a deeper question: how do we actually know something is true?
One way is through proof. A proof starts from a few basic statements and rules, and step by step derives a new statement from them. The key challenge, then, is choosing the right starting points. Mathematicians eventually chose sets—simple collections of objects—as the most fundamental building blocks. From a few basic assumptions about sets, we can define numbers, define addition, and gradually build the entire structure of mathematics.
Even a statement as simple as 2+2=4 can therefore be derived from these basic principles. In this session we will not focus on technical details, but on understanding the overall structure of the idea. The reasoning can be followed in simple terms, even by non-mathematicians, and it reveals something remarkable: from a small number of simple starting points, an enormous world of mathematical knowledge can be built.
Along the way, we will also look at the historical path that led to this view—how mathematicians gradually refined these ideas over centuries in an intellectual quest to understand the foundations of mathematics.
This session will be led by Jordi Molins.

**18:30: Welcome**
Grab a drink, and a seat until everybody arrives!
**18:45 Intro by Host Neciu Dan**
**19:00 Kibble: Designing Hybrid Components for Native and Web**
Speaker: [Traian Stanciu](https://www.linkedin.com/in/traian-stanciu/) Senior Software Engineer at Rover.com
Building a component library that runs on web, React Native, iOS, and Android without diverging into chaos is harder than it sounds. This talk digs into how Kibble—Rover's design system—handles the gap between platforms through a file-naming convention (`.tsx` / `.native.tsx` / `.common.ts`), a unified event abstraction that bridges web click and native press events, and a token pipeline that generates Swift, XML, CSS, and TypeScript from a single source of truth
**19:25 React Native in a Native App: Brownfield Integration & Over-The-Air Deployments**
Speaker: [Luca Barone](https://www.linkedin.com/in/lucabarone95/) Mobile Engineer at Rover.com
A practical look at how Rover.com ships React Native screens inside fully native iOS and Android apps — without rewriting them from scratch. We'll cover the "brownfield" integration pattern, how JS and native code communicate through bridge modules, and how we deploy JavaScript updates to users in minutes using Expo EAS Update, completely bypassing the App Store review cycle.
