We often think of reasons as tools for justifying our choices. But if that’s all they are, why is it that we can feel “reasonless” in the middle of doing something — or confident in a choice we can’t explain to anyone else? In our next Curiosity Café we will begin by thinking about reasons as justifications. What makes a reason a good reason? What has to be true for a reason to actually justify an action — and why do we so often feel compelled to justify ourselves in the first place? Then we will turn to the question of where reasons come from. The answer seems deeply personal — your reasons feel like yours — yet philosophers argue that some reasons may be universal, rooted in human nature, culture, or ethics. But which is it? And does having a reason to do something mean, on some level, that you want to do it? Finally, we ask: can any choice be fully justified? The “Why Game” suggests that however good your reason is, someone can always ask why again. What does this justificatory regress mean for the choices we make and what responsibility do we have, individually and collectively, to seek good reasons for how we live and treat each other? Join our co-moderators Jesse Vriend and Marybel Menzies to explore these questions and more on May 5th! **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-reasons-justification-tickets-1988294578608) to attend this event.

We aim to create community around exploring everyday concepts and experiences so that we may live more intentional, thoughtful, and meaningful lives. We use philosophy as a tool with which we can come to a richer understanding of the world around us. By offering activities, spaces, and other opportunities for conversation and co-exploration, we hope to enable the meeting and fusion of individuals and their ideas. Everyone is welcome, regardless of background: indeed, we believe the journey is best undertaken alongside explorers from a variety of disciplines, cultures, backgrounds, and experiences. Find out more about Being and Becoming [here](https://beingnbecoming.org/). About the Curiosity Café Series: For those of you who haven’t had the opportunity to join us at our Curiosity Cafés and are wondering what they’re all about: every two weeks, we invite members of our community to come out to the Madison Avenue Pub to engage in a collaborative exploration of our chosen topic. Through these events, we aim to build our community of people who like to think deeply about life’s big questions, and provide each other with some philosophical tools to dig deeper into whatever it is we are most curious about.

You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

ABCD Reads "**[What We Can Know](https://tpl.bibliocommons.com/v2/record/S234C4683360)**" by Ian McEwan. [[RESULTS](https://opavote.com/results/6276009911648256) of the poll for this event] **:: ABOUT THE BOOK ::** "A quest, a literary thriller and a love story, *What We Can Know* spans the past, present and future to ask profound questions about who we are and where we are going. 2014: A great poem is read aloud and never heard again. For generations, people speculate about its message, but no copy has yet been found. 2119: The lowlands of the UK have been submerged by rising seas. Those who survive are haunted by the richness of the world that has been lost. Tom Metcalfe, a scholar at the University of the South Downs, part of Britain's remaining archipelagos, pores over the archives of the early twenty-first century, captivated by the freedoms and possibilities of human life at its zenith. When he stumbles across a clue that may lead to the great lost poem, revelations of entangled love and a brutal crime emerge, destroying his assumptions about a story he thought he knew intimately. *What We Can Know* is a masterpiece that reclaims the present from our sense of looming catastrophe, and imagines a future world where all is not quite lost." (from [Goodreads](https://www.goodreads.com/book/show/223854881-what-we-can-know)) "A love story about both people and the words they leave behind, a literary detective story which reclaims the present from our sense of looming catastrophe and imagines a future world where all is not quite lost." (from [Bookmarks.reviews](https://bookmarks.reviews/reviews/what-we-can-know/)) **:: ABOUT THE EVENT ::** You are welcome to arrive 30 minutes before the event and stay 30 minutes or longer afterward to connect with other attendees outside the book talk. Please ensure you have read the book before attending (though finishing any book is not a barrier to participating, as long as you don't mind spoilers). First-time attendees can join for free. If the event is full, we maintain an unofficial waitlist. Please send [Michael](https://www.meetup.com/members/55295192/) a direct message for more information, in either case. We request a $3 contribution from regular attendees to help cover our monthly meetup costs. **:: ABOUT OUR NEXT BOOK ::** At the end of each event, we will ask for nominees for our next book. If you have a good one in mind, please ensure it is between 200-400 pages long, available from the Toronto Public Library, and counts as contemporary literary fiction (though these are not hard and fast rules). When enough nominees are collected, Michael will send the members a direct message with a link where you can vote.

**When:** Tuesdays, 7:00 PM - 9:00 PM, Winter/Spring 2026 **Where:** 792 Glencairn Ave., Toronto, ON **Attend online via Zoom:** https://us02web.zoom.us/j/89671983431?pwd=hoYVrQG1EF4ibvIieyTnavmXxWcy5h.1 **Main Text:** [Deity, Cosmos and Man](https://www.theosophy.world/sites/default/files/ebooks/DeityCosmosAndMan_GFarthing.pdf) by Geoffrey Farthing If the above link is broken, paste this into bar for free PDF: https://www.theosophy.world/sites/default/files/ebooks/DeityCosmosAndMan_GFarthing.pdf This third part of our **Intro to Theosophy** series turns to *Deity, Cosmos and Man* by Geoffrey Farthing, a clear and reliable guide to the foundational teachings of Theosophy as originally presented by **Helena Petrovna Blavatsky** and her Adept teachers. This study explores a living, intelligent universe governed by unity, law, and vast evolutionary cycles, and examines how the human being reflects these same cosmic principles within their own inner constitution. Emphasis is placed on Theosophy not as a belief system, but as a coherent body of knowledge—offering insight into consciousness, post-death states, hierarchies of beings, and the deeper purpose of human evolution. Alongside discussion and reflection, the group will explore guided experiential exercises designed to support awareness, perception, and integration. The intention is to: * Develop a clear understanding of core Theosophical principles * Explore the relationship between cosmos, consciousness, and the human constitution * Encourage experiential insight alongside study and dialogue * Support inner balance, discernment, and conscious self-development This class is suitable for: * Students continuing from Parts 1 and 2 of the Intro to Theosophy series * Those interested in Theosophy, cosmology, and human evolution * Participants seeking a grounded, psychologically oriented approach to spiritual study * Anyone curious about consciousness, meditation, and the deeper structure of reality No prior experience with Theosophy, yoga, or meditation is required. Only curiosity, openness, and a willingness to explore thoughtfully.

We are following our favourite trivia host, Simon from Are You Smarter than a Scottish Guy, to one of his other weekly locations: One-Eyed Jack's at 287 Richmond Road (between John and Peter Streets). The beer selection at this location is quite minimal but their food menu is good - https://www.oneeyedjackpub.com/torontomenu. They have a $0.95 wing special with lots of flavours. The trivia starts at 7:00pm with first question at 7:15 pm. We have a pair of tables (12 people) reserved under Steve so far. Serious RSVPs only as no-shows prevent us from fielding a complete team. Top prizes is a gift certificate for the next visit. Other prizes are a free round for the table and nachos. There is also a small prize for best team name, so put on your creative hat; the host seems to like puns and prefers short team names. Let's have some fun, eat some wings, and hopefully win!

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/xwjDdVSw3E **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.

Struggling with motivation and focus as you hammer away on your manuscript at home? Want to join a community of writers as we embrace the joys and pains (mostly pains) of writing together? Bring your laptop, pen & paper, old-school typewriter, or futuristic writing gadget, and join an enthusiastic community of science fiction and fantasy writers as we work on our current projects in the same space. The format will be similar to our online writing sprints: 30-minute blocks of focused, quiet writing time (the sprints), interspersed with breaks where we can chat, ask questions, and share our writing experiences.

[Summary] This meetup is for those who are interested in code, web development, design, cloud, or AI. All levels are welcome, so feel free to bring your laptop and discuss what you are working on or what you are learning. You can share your projects and ideas with other participants freely. There are outlets and WiFi, drinks are about $5 for tea, they take card only. [Price] Attendance is FREE. But you need to buy something from the venue. [Policies] \- We do not tolerate harassment of our members \- We remind users that that this meetup is intended for networking and hobby development\, and any attempts at using this meetup event as a dating platform will not be not be tolerated Further information: https://torontostack.exchange/

This panel brings together identity leaders to challenge today’s assumptions, debate what’s hype versus real architectural shift, and explore where existing identity guidance breaks when agents start acting on our behalf. Through sharp, opinion-led questions on delegation, standards, continuous decisioning, and auditability, panelists will surface the principles and industry changes that will matter most in the next 12–24 months. **7:30pm -** Network **8pm -** Event and attendees exit venue Have a great day, An

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

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. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
