Spinoza on Religion & Politics: The Theological-Political Treatise (Part 1)
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".

About the Centre for Ethics (http://ethics.utoronto.ca):
The Centre for Ethics is an interdisciplinary centre aimed at advancing research and teaching in the field of ethics, broadly defined. 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.

We will discuss options trading and investing strategies, as well as the skills needed to start. It is a **casual meetup to meet people who are interested in trading or building a career around it, especially algorithmically. No "financial gurus" are welcome.**
Join us for a meetup where we share trading ideas, and connect with others who share a common interest in investing.
Algorithmic trading is commonly used by large institutional investors and market makers, but it is also accessible to retail traders. It offers several advantages over manual or discretionary approaches—particularly in minimizing psychological errors that often impact human traders.
Some of the topics we usually discuss:
\- Reasons for investing
\- Limitations of being a retail trader
\- Practical tools: brokers\, APIs\, data sources\, real\-time implementation
\- Brainstorming ideas: strategies that may be working today
**Note this even is not sponsored or endorsed by any business where we are meeting. We are just using their space for casual meetup event.**

Mob Programming at Mofer Coffee
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.

What If Your AI Could Be a Team? - Chad Green
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise.
We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration.
Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team.

Duty vs. Results: What Makes an Action Moral?
When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches.
* **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason.
* **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes.
## Discussion Questions
1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie.
2. **Can good intentions rescue a bad outcome?**
3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome?
4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend?
5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles?
6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way?
7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time?
8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?
