Libera Animae - Freeing the Soul
Main Library, Meeting Room 3B

All backgrounds are welcome.
In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation donโt just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

Prompt vs. Paintbrush
AI is changing how art is made. But when does it stop being your work and start being the machineโs?
This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation?
We encourage audience participation during this event that will be moderated by Chris Slee.
Whether youโre deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

This month's prompt concerns the idea of the โwarrior philosopherโ (seemed appropriate in these times)--that is someone whose understanding of violence, power, and justice is forged through direct experience of war. We are looking at Major General Smedley D. Butler, a highly decorated U.S. Marine raised in a Quaker (pacifist) tradition who later became a prominent critic of American militarism (there is a wonderful biography of Gen. Butler called "Gangsters of Capitalism")
Butler's argument in *War Is a Racket* (1935): that many U.S. interventions were driven less by national defense than by corporate and financial interests, with Butler portraying himself as an enforcer for business and Wall Street. We can consider the moral ambiguity of his insider critiqueโwhether complicity strengthens or undermines credibility and also consider some of the concrete reforms he proposed (e.g., โconscriptโ capital before soldiers, restrict the military to coastal defense, and have only those who fight decide on war).
Butlerโs life arc clearly changed from pacifist upbringing to warrior to antiwar crusaderโand asks whether true understanding of peace requires firsthand knowledge of war, and what that implies about the cost of suffering. So do we need to suffer to understand suffering? Do we have to experience war to appreciate peace? As one more question: in the movie "A Few Good Men" Jack Nicholson's character says that "you have the luxury of not knowing what I know" so do most of us go through life oblivious to real violence and suffering? See you at Drunken Philosophy!
