Practical Philosophy Meetup - Singapore 🇸🇬
🏛️ **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/Hg7zL8ClpzM3agJCvw5HDS), 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/Hg7zL8ClpzM3agJCvw5HDS).
* 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/Hg7zL8ClpzM3agJCvw5HDS) 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/).

Kalari Group Class (All Ages, All Levels)
**For ages 8 and above.**
These 3 traditional martial art forms will be taught during the 2 hour class:
* Kalaripayattu
* Silambattam
* Adimurai
**About Kalaripayattu**
Thought to be one of the most ancient martial arts in recorded history, Kalaripayattu is derived from two words, “Kalari” signifying battlefield or arena and “payattu” which translates to the words ‘practice’ and ‘exercise’.
**About Silambattam**
Hailing from the region of Tamil Nadu (India) where it emerged around 1000 BCE, Silamabattam is a popular variant of weapon-based martial arts which is performed with the aid of specific weapons, primarily Rattan staffs, short sticks, deer horns and swords.
**About Adimurai**
Adimurai is a generic term applied for the indigenous martial arts of the Indian/Tamilian archipelago. Adimurai in general refers to the sport of using techniques derived from Indian and Tamil martial-arts. It uses kicks and boxing-mannered punches to defeat an opponent in ways that are analogous to standard present-day boxing. The manipulation of joints as well as certain locking techniques also form the basis of Adimurai.

Using Philosophy to Cope with Current Events
So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!

Bring your work or your hobby, hang out, and code with us.

Humanist Program: Fighting the Efforts to Insert Religion into Public Education
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.
Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk.
Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association:
They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved.
Going forward our meetings will be hybrid. You can meet us in-person or attend online
