The host has requested RSVPs for this event


My name's Logan Chipkin. I'm hosting the second Philly Rat Fest the weekend of June 30th - July 2nd, 2023.

Join us for workshops, talks, good food, new friends, old friends, philosophizing, and laughing.

Last time, we had a very successful event in Philadelphia. People flew from all across the world to discuss, debate, and learn about some of the deepest ideas Rats of all stripes care about.

While online communities serve many purposes, there's nothing quite like meeting up in person to fortify a community.

To be clear, Rats of all stripes are welcome to join! Last time, we had plenty of rationalists, crit rats, post rats, and Bayesians.

If you have any questions, email me at, or DM me on Twitter @chipkinlogan.
