**SUBSCRIBE TO [THE MAILING LIST](https://torontorationality.beehiiv.com/). EVENTS ARE NO LONGER POSTED HERE.** ​Arguing about important things doesn’t usually lead to people changing their mind. Double Crux is a technique for making discussions more productive and understanding the actual reasoning of those who disagree with us. Sometimes it even helps to better understand the foundations of your own beliefs. Together, we'll learn about [Double Crux](https://www.lesswrong.com/posts/ya59PtGeYnCG25eWn/double-crux-in-a-box), and then break into pairs with someone we disagree with to practice finding out why our views are different and what might change our minds. ## Location Enter the Mars Atrium via University Avenue entrance. We'll meet at the food court in the basement. I'll be wearing a bright neon yellow jacket. ## Detailed Directions to the Food Court Enter from University Avenue and walk east until you see escalators. Take the escalators down. The food court is to the east of the escalators. If you are lost/confused, ask a security guard to direct you to the food court.

We experience and produce humour through the memes we spread and the inside jokes we share with friends, and we even use it when facing life’s most difficult challenges. Humour can help us bond, cope, and rethink our assumptions. But what makes something funny? Why do humour and the laughter it produces play an important role in our culture? One answer is that humour can help break down barriers and bring people together. As Victor Borge once said, “Laughter is the shortest distance between two people.” Humour can also be used as a social instrument to call out misconduct. How is it that humour fosters community and division at the same time? At our next Curiosity Café, we’ll revisit the silly and serious sides of humour, and explore the role that humour plays in how we connect, think and live. Together, we’ll discuss questions like: * How does humour help break down barriers and bring people together? * Does humour have a unique ability to help us find common ground and strengthen relationships? * On the other hand, does how we respond to humour have implications for our social capital? * How might jokes or humour be perceived by people from different backgrounds? * Is it possible to create humour that’s both provocative and inclusive? * How might humour give us a sense of control? * What is or should be the role of comedy in society? Join us for a lively and collaborative conversation moderated by Erik Ai and Dylan Michels, where we’ll explore questions, new and old, and (hopefully) share plenty of laughs along the way. **Space is limited!** **Please obtain a “Pay-What-You-Can” ticket from Curiosity Café at [this link (click here)](https://www.eventbrite.ca/e/curiosity-cafe-revisited-no-laughing-matter-humour-in-our-lives-tickets-1985339500891) to attend this event. You need a ticket to be admitted.** See the above link for more info about tickets and other options including a limited number of free tickets. Come and hang out with us, grab food, and read through our handout from 6-6:30pm. Our structured discussion will run from 6:30-8:30pm with a 10 minute break in the middle. Hope to see you there! ***__________________________________________________________________*** This event is brought to you by [Being and Becoming](https://beingnbecoming.org/), a Toronto based non-profit.

Join us for a focused discussion on one of the most fragmented yet transformative periods in Chinese history: the Two Jin Dynasties and the Northern and Southern Dynasties (265–589). Following the collapse of the Three Kingdoms, the Western Jin briefly reunified China, only to fall into internal strife and invasion. What followed was centuries of political division between northern regimes founded by non-Han elites and southern courts led by Han Chinese aristocracy. This era witnessed large-scale migration, cultural fusion, the spread of Buddhism, and the gradual reshaping of Chinese identity and statecraft, setting the stage for reunification under the Sui and Tang. **Topics for Discussion** * The Rise and Fall of the Western Jin * The War of the Eight Princes * The Yongjia Disaster and Northern Collapse * The Eastern Jin and Southern Aristocratic Politics * The Sixteen Kingdoms in the North * The Northern Wei and Sinicization Reforms * Division Between Northern and Southern Dynasties * Mass Migration to the South and Economic Shift * The Spread of Buddhism and Cultural Transformation * Aristocratic Clans and the Nine-Rank System * Military Weakness and Court Intrigue in the South * The Road to Reunification under the Sui Dynasty
