About Freethought Day
Sacramento Freethought Day combines the fun and atmosphere of a fair with the education and activism of a conference. It's a festival of freethought. We'll have speakers and live entertainment, family activities, an authors' panel with Q&A, and more!
The universe is a big place and, although we’ve learned so much about it, there is still much to be discovered. So many things bigger than our planets and smaller than our atoms.
Humanity is naturally curious about our universe. We see something unknown and demand to know what it was or how it happened. Our wonderment touches every aspect of life from biology to sociology, from politics to chemistry sets. We have a thirst to understand.
And so we ask, we test, and we share. The scientific method cultivates our curiosity into knowledge. Humanity’s spirit is embodied in The Wonders of Magic and Reason.

The History of Freethought Day
Freethought Day dates back to 1692, during the time of the Salem Witch Trials. Massachusetts Governor William Phips wrote, on October 12, about the quagmire that the trials had degenerated into, in part by a reliance on "evidence" of a non-objective nature and especially "spectral evidence" in which the accusers claimed to see devils and other phantasms consorting with the accused.
