Lecture Series

Free & Open

Our monthly lecture series is presented as free and open to the public for all to attend.


Our lecture series is a means of educating and promoting ideas of interest to atheists and the greater Austin community.

Topics of Interest

Topics usually focus on subjects such as science, skepticism, the impact of religion, philosophy, church/state separation, and community activism.

Academic for All

While many of our lectures tend to be academics, speakers target their talks to a lay audience of people who want to enrich their understanding.

Atheist Community of Austin

The Atheist Community of Austin is a 501(c)(3) non-profit organization dedicated to promoting positive atheism and the separation of church and state. The ACA serves the local Austin community through outreach programs, providing informational resources and various volunteer activities. In addition, the ACA serves the community-at-large through free online portals including informational wikis, regular audio/video podcasts and interactive blogs.

We define atheism as the lack of belief in gods. This definition also encompasses what most people call agnosticism.
