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/).

Humanist Program
Our January program is privileged to have Kristen Tregar as our speaker. Ms. Tregar is the co-author with John de Lancie (the actor who portrayed the character Q on Star Trek next generation) of a radio play depicting the events surrounding the Kitzmiller v. Dover Area School District trial. The trial decided the issue of some of the Dover school district board members attempting to insert creationism disguised as "intelligent design" into the 9th grade biology curriculum. She will discuss the trial and the process of writing the play. (Bob Leonhard has seen the play and it is riveting and tense). Ms. Tregar's bio is below:
Kristen Tregar is a dramaturg, director, playwright, and theatre teacher. She earned her Ph.D. in Drama and Theatre from the UC San Diego and UC Irvine joint program. In addition, she has a MS in Forensic Science from City University of New York- John Jay College of Criminal Justice and a MA in Educational Theatre from New York University- Steinhardt School of Culture, Education, and Human Development. In 2013, in collaboration with Irish colleagues, she founded *The Ireland Project*, an intercontinental devised theatre work with high school students in New York and Tallaght, Ireland. Her original short story "Far From Here" was recently published in *Stay Awhile Longer: More Scenes From Temecula Valley*. She has two rescued dogs (Kira and Harry) and she rides, competes, and foxhunts with her horses, Andromache and Baker Street Irregular.
Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk.
Going forward our meetings will be hybrid. You can meet us in-person or attend online
