CSICon is already one of the planet’s premier skeptics conferences, where hundreds of critical thinkers come to Las Vegas, the city of illusions, to hear from the leading lights of science and skepticism.

It’s true, conspiracy theorists, quacks peddling fake medicine, and the deniers of evolution, climate change, and vaccine science are bigger threats than ever.

With CSICon 2018, let’s show them that they just met their match.

Ingersoll Museum Silver Anniversary Celebration

2018 is the twenty-fifth anniversary season of the Robert Green Ingersoll Birthplace Museum in Dresden, New York; it opened to the public in 1993. It is North America’s only freethought museum. In later years it gave rise to the Freethought Trail, which celebrates west-central New York State’s unique contribution to nineteenth-century radical reform causes. Join us in Syracuse, New York, for the celebration!
