 After Richard Dawkins' success with the book "The God Delusion", he created the foundation with its headquarters in the United States to work toward a world in which religion no longer interferes with the advance of science and in which people use their critical thinking skills to evaluate theist claims about the nature of reality.Dawkins complained of the difficulty he faced in gaining tax-free status, which he attributes to the secular nature of the organization.In contrast to the presumption by officials that religious organizations benefit humanity without evidence (for instance Our Lady of Perpetual Exemption), he points to a letter he received from the British Charity Commission requesting evidence for the claim that the advancement of science is connected to the public good.
