**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:** £50 (concessions £30) There will be 2 breaks of 15 minutes (refreshments included in the price)

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? *Please do your own research and share resources related to this topic in the comments below.* —————————————————————————————— **💛 Support The Examined Life** Enjoying the discussions?

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.
