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/LB5EKxC9JsN7S1wVok3vXe?mode=gi_t), 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/LB5EKxC9JsN7S1wVok3vXe?mode=gi_t).
* 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/LB5EKxC9JsN7S1wVok3vXe?mode=gi_t) 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.

Mindfulness Walks
Join me for a small, mindful photography walk in nature. (**NOTE Time is 9:00 AM EST(Meetup is having technical Issue))**
This is a slow, intentional gathering — not focused on fitness or perfect photography — but on simply pausing, observing, and being present.
We’ll walk at a gentle pace, with moments of quiet, and a few light prompts to help you notice details you might normally miss.
📷 You don’t need any photography experience — a phone camera is enough.
This is also not a business networking event. It’s a calm space to connect with nature and, if it feels natural, with like-minded people.
🌿 What to expect:
• A slow-paced, relaxed walk
• Moments of silence and observation
• Simple reflection prompts
📍 Location: [ Red Trabue Nature Preserve]
⏱ Duration: \~90 minutes
Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs.
This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context.
We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing.
