Let's Discuss... Penal System
We all want 2 things from justice. We want the guilty caught and held, so the rest of us are safe. We also want to be sure we never crush someone who did nothing wrong. But we can't have both. Lean toward catching every criminal, and innocent people get swept up. Lean toward protecting the innocent, and some dangerous people slip through. Benjamin Franklin landed on one side: better a hundred guilty go free than one innocent suffer. The trouble starts when those hundred are real, and they're out.
What is prison actually for? to punish, to protect us, or to fix people?
When a sentence is short, is that mercy or is that punishment of the victim?
Which mistake can you live with: jailing the innocent, or freeing the guilty?
Can a court really say "innocent until proven guilty" after the public already decided?

Practical Philosophy Club Meetup - London ๐ฌ๐ง
**๐๏ธ 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 โofficialโ philosophy knowledge required! ๐
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 ๐
๐ **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/B6fqS6HGujq8gb3a0kl5pS), along with jump-off points to get the conversation going.
When groups get bigger than 7-8 people, itโs 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:
* 14:00-14.15 - People arrive and chat, get to know each other before the โofficial' start.
* 14:15-14:20 - 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.
* 14:20-15:20 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the โjump-offโ questions as needed, but they are just there to help guide the conversation. Itโs not obligatory to answer them.
* 15:20-15:30 - We do a group conclusion of the things we discussed, and then we typically take a photo and go on our way :) If you don't want to be in the group photo, there's no pressure, it's just a way to close out the meeting. We occasionally have an unofficial social so the different groups can mingle afterwards too!
**๐งงPRICING?**
Practical Philosophy Club is FREE to attend, and we operate on donations.
If you'd like to donate to support our running costs, that helps keep our group self-sustaining. Donations are 100% voluntary, but your contribution is appreciated! QR codes to donate will be present.
Teaโs and coffees and are paid by the individual should they wish to have them.
**๐ WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY**
๐ฃ โI feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting whatโs right and wrongโ - Ekam
๐ฃ โI 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.โ - Daniel
**๐ค FAQ**
* What will we talk about? What's the topic?
The topic for the week is shared every week in the Whatsapp group before the session. We try to add the topic to the comment section on this event page as well but if you donโt see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/B6fqS6HGujq8gb3a0kl5pS).
* Do I need to study or read anything to attend?
No preparation is necessary. This isnโt 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 weโll 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 donโt 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/B6fqS6HGujq8gb3a0kl5pS) 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/).
๐ค**POLICY**
To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group. Practical Philosophy reserves the right to enforce this policy at its discretion to maintain a safe and respectful environment.

Workshop: The Sacred Geometry of Sound
**This is a paid event, tickets available [here via eventbrite](https://www.eventbrite.co.uk/e/workshop-the-sacred-geometry-of-sound-tickets-1990188956744?aff=oddtdtcreator&_gl=1*6our0c*_up*MQ..*_ga*MTIzNzU4NTQxLjE3Nzk0ODUzNTk.*_ga_TQVES5V6SH*czE3Nzk0ODUzNTgkbzEkZzEkdDE3Nzk0ODYxMjUkajQxJGwwJGgw&keep_tld=true).**
**3-hour workshop will explore how the harmonious intervals of music serve as a model for universal structural principles.**
There is a long history of connection between music, mathematics, science and philosophy. From the ancient idea of the *music of the spheres* to the cosmological reflections of Kepler, Leibniz, Fludd, Newton and later thinkers such as Hans Kayser, sound and harmony have been understood not only as a musical phenomenon, but as a geometrical pattern inherent in nature. Myths across many cultures also express the concept that the universe was created by sound, and according to modern quantum field theory matter and energy fundamentally behave like vibrating waves.
The aim of this workshop is to share these ideas with a wider audience and popularize the interdisciplinary field called *harmonic research* or *harmonics*, in which the harmonious intervals of music serve as a model for universal structural principles.
**Content:**
* Fundamental harmonic principles in music and mathematics, including practical demonstrations on the monochord
* Harmonic proportions in nature and architecture
* The concept of harmony as a universal organizing principle and how we can apply this to our individual and collective lives
*
The workshop leader, Sabine Leitner, has an MA in music and completed the 2-year course 'Fundamental Research into Harmonics' at the Hans Kayser Institute at the University of Music and Performing Arts in Vienna (1990-1992). She also has an MA in Philosophy and an MA in Leadership Coaching. She is the director of the New Acropolis School of Philosophy in London.
This workshop has been organized to celebrate the International Day of Music and to promote the theme of 'Philosophy and Science'.
**Admission:** ยฃ50 (concessions ยฃ30)
There will be 2 breaks of 15 minutes (refreshments included in the price)

Drunken Philosophy: Where Is Everybody? The Fermi Paradox and the Great Filter
Welcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle.
**Optional topic for this meetup: Where is everybody?**
In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox.
One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread.
Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for.
**Questions to wrestle with:**
* Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving?
* Where do you bet the filter sits, behind us or ahead of us, and why?
* If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming?
* Two principles pull opposite ways here. The principle of mediocrity (the Copernican principle, Sagan's "no privileged place in the universe") says we are ordinary, so what happened on Earth probably happened everywhere, which makes the silence scream louder. The anthropic principle says of course we find ourselves somewhere life was possible, since we could not observe anything else, so our being here may say almost nothing about how common life is. Which lens do you trust, and does the silence still demand an answer once you account for observer selection?
* And if we did confirm life out there and had to accept we are not special, what would that do to belief in a higher power, and would shedding (or keeping) that belief help or hurt our odds of pulling together as one species?
* Does any of this change how you live, or how humanity should be spending its time and money right now?
As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.
