Wine Therapy (Huntington)
Cozy Wine Therapy events are back. This is my kind of therapy session. In the comfort of my living room (or a volunteer), we will unwind and share our personal highlights and lowlights since we last met, and with the help of friends (and wine) we will "release" any negativity we may be holding onto as well. We will be here to listen and share advice if that is what's needed. Sometimes just having someone to listen is all we need to feel better. Be prepared to share! No couch surfers allowed. :-)
My living room is a safe non-judgmental space. What is shared will not be discussed beyond my living room unless you decide to share.
Feel free to bring a bottle of wine to supplement the stock, or a snack, if you wish.
NOTE: My apartment is NOT good for those with cat allergies. I am conveniently located a mile from Huntington Metro Station off of Huntington Ave. with plenty free parking. To be invited into my home, I will have had to meet you at an event prior. Makes sense, right? I will message the group my address a few days before. Make sure your notifications are ON.

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?
