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?

Fun & easy way to play more tennis (read event description)
We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches.
These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun!
Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up:
https://www.playyourcourt.com/tennis-community/columbus-oh/meetup/
If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works.
Happy hitting!

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
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.

The Mythical Data Warehouse: The World Is Hybrid
Dear Illinois Prairie PUG members,
Our next meetup will take place in a **new location**. Please read **the whole announcement** carefully to note all the changes.
Our new meeting place is **Chicago Innovations at 1 W. Monroe**.
*Talk Title*: pg_lake: Unifying transactional and analytical data with Postgres
*Speaker*: Elizabeth Christensen, Snowflake
*Talk Description*
The data world used to be defined by “transactional" (OLTP) and “analytical” (OLAP) workloads, but we’ve asked ourselves, “Why not both?” A new series of extensions called pg_lake has just been released to connect Postgres to object storage and open table formats - like csv, Parquet, and Iceberg. pg_lake bridges the two worlds of transactional and analytical data for a vendor neutral, open source, unified data stack.
This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics.
pg_lake is more than just an extension. It is the foundation to a fully unified data path with 100% open source tools backed by PostgreSQL, DuckDB, Iceberg, and Polaris.
*Agenda*
5:20 - doors open
5:30 - pizza arrives
6:00 - 6:10 - Hettie D. Opening remarks
6:10- 6:20 - Hettie D. Data warehouse history overview
6:20 - 6:50 Elizabeth C. pg_lake: Unifying transactional and analytical data with Postgres
6:50 - 7:00 Q&A
7:00 - 7:50 - Open discussion and networking
7:50 - 8:00 - Cleanup time and closing
*Notes about our new venue*.
I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities.
You will notice the change in the RSVP form.
We are thankful to our hosts and promise to be responsible.
We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/).
We do not want to waste food, so please indicate your dietary preferences.
We will not close the RSVP in the morning of the meetup, but please do your best to RSVP in advance so that we can order the appropriate amount of food and drinks.
Also, all meetups will be hybrid - please don't forget to indicate whether you are attending in-person or virtually.
Thank you, and I look forward to seeing you all at our new location!

Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!
Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life.
Mission: grow, support, and provide community for atheists in Central Ohio.
Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision.
Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA). AoC members are invited to join this OA meetup and/or OA Facebook group ( https://www.facebook.com/groups/omnipresentatheists/ ) but are free to continue conversations on the AoC Facebook group ( https://www.facebook.com/groups/columbusatheists/ ). AoC was founded in 2012 as a networking, social group for Central Ohio area humanists, skeptics, atheists, agnostics, nonbelievers, freethinkers, and the curious. It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge.
Omnipresent Atheists is a member of the Columbus Coalition of Reason (ColumbusCoR.org). Omnipresent Atheists is a member of the Columbus Coalition of Reason ( http://www.ColumbusCoR.org ). Omnipresent Atheists endorses the mission of the Secular Coalition for America ( http://secular.org ).

LLM Showdown: ChatGPT vs Claude vs Gemini vs Local Models
Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability.
You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
