The Freethinker Competitors

FFRF works to promote nontheism and defend the constitutional separation between religion and government. With more than 40,000 members, the nonprofit FFRF works as an effective state/church watchdog and voice for freethought (atheism, agnosticism, skepticism).

The Center for Inquiry strives to foster a secular society based on reason, science, freedom of inquiry, and humanist values. The Center for Inquiry (CFI) is a 501(c)(3) charitable nonprofit organization dedicated to defending science and critical thinking in examining religion. CFI’s vision is a world in which evidence, science, and compassion—rather than superstition, pseudoscience, or prejudice—guide public policy. To make a better world, we need to use our heads and our hearts. To confront the challenges that face us as a planetary civilization, we need to use the tools of science and reason guided by compassion and respect for the dignity of every individual. To move forward, we need to discard old superstitions, prejudices, and magical thinking and embrace facts, evidence, and critical thinking. It’s about more than whether or not God exists. It’s about more than whether ghosts roam among us, aliens hover above us, or psychics can see within us. The Center for Inquiry (CFI) strives to foster a society free of the dogmatic influence of religion and pseudoscience; a society inspired by the ideals of the Enlightenment, the wonders of science, and the limitless potential of human intelligence and creativity; a society in which beliefs are not granted the same rights as people, where the freedom of expression is enjoyed by all, and all ideas are open to the scrutiny of reason. Secular government. Free inquiry. Critical thinking. Humanist values. This is the Center for Inquiry.

American Atheists is a nationwide non-profit organization that advocates for the absolute separation of religion and government, elevates atheism and atheists in the public sphere, and addresses issues of First Amendment public policy.
