Baruch Spinoza's *Theological-Political Treatise* (1670), originally published anonymously, is one of the most important and controversial philosophical works of the early modern period. Aiming to "liberate the individual from bondage to superstition and ecclesiastical authority", the work has been characterized as one of the most significant events in European intellectual history, laying the groundwork for ideas about liberalism, secularism, and democracy. In it Spinoza discusses at length the historical circumstances of the composition and transmission of the Bible, demonstrating the fallibility of both its authors and its interpreters. He argues that free enquiry is not only consistent with the security and prosperity of a state but actually essential to them, and that such freedom flourishes best in a democratic and republican state in which individuals are left free while religious organizations are subordinated to the secular power. His Treatise has profoundly influenced the subsequent history of political thought, Enlightenment philosophy, Bible hermeneutics, and textual criticism more generally. The work attracted harsh criticism and vigorous attempts by religious leaders and conservative authorities to suppress his work entirely, with one critic describing it as being "Forged in hell by the apostate Jew working together with the devil". **\* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \*** This is Day 2 of a two day conference presented by the University of Toronto's Centre for Ethics on the contemporary relevance of Spinoza's *Theological-Politico Treatise* (or *Tractatus Theologico-Politicus*) published in 1670.

The Centre seeks to bring together the theoretical and practical knowledge of diverse scholars, students, public servants and social leaders in order to increase understanding of the ethical dimensions of individual, social, and political life. In pursuit of its interdisciplinary mission, the Centre fosters lines of inquiry such as (1) foundations of ethics, which encompasses the history of ethics and core concepts in the philosophical study of ethics; (2) ethics in action, which relates theory to practice in key domains of social life, including bioethics, business ethics, and ethics in the public sphere; and (3) ethics in translation, which draws upon the rich multiculturalism of the City of Toronto and addresses the ethics of multicultural societies, ethical discourse across religious and cultural boundaries, and the ethics of international society. The Ethics of A.I. Lab at the Centre For Ethics recently appeared on a list of 10 organizations leading the way in ethical A.I.: https://ocean.sagepub.com/blog/10-organizations-leading-the-way-in-ethical-ai

**🏛️ 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://tally.so/r/KYLZlD), 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 is operated entirely on voluntary donations! If we are meeting in a café, buy a beverage! Donations are 100% voluntary, but they help us to bring the gift of deep conversation to people around the world. If you'd like to support, you can [donate here](https://www.zeffy.com/en-CA/donation-form/donate-to-practical-philosophy)! (Practical Philosophy is a registered Canadian charity) **💛 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** * **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. * **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 often, 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://tally.so/r/KYLZlD)[ ](https://chat.whatsapp.com/FtwkSBwyNUbCTSOq5H4Kmn?mode=gi_c)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/). 🤝**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.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/yvAGbh4PpD **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

Adapted from the Academy Award®-winning film, this play-with-music is packed with humour, sword fights, disguises, and a delightful play-within-a-play. With plenty of Shakespeare’s own words woven throughout, it’s a fast-paced, feel-good night at the theatre full of wit, romance and backstage drama. *** **TICKETS** **Discount Tickets:** $30 (includes HST and order fee) **Regular Tickets:** $39.50 adults / $36.50 seniors 60+ (includes HST) + $4.50 order fee **Meetup Fee:** $3 (per person paid at time of purchase) *** **HOW TO PURCHASE** Sign up on this event page and use the promo code THMBSL26 to get your discount ticket(s) **[online](https://alexandershowcasetheatre.com/shows/shakespeare-in-love/)**.
