Much of human progress has been in defiance of religion or of the apparent natural order. The defiance of religious and secular authority has led to democracy, human rights, and the protection of the environment. Humanists make no apologies for this. Humanists twist no biblical doctrine to justify such actions.
The only difference between a Religious Humanist and a Secular Humanist is what they do on Sunday.
Though we [Humanists] take a strict position on what constitutes knowledge, we are not critical of the source of ideas. Often intuitive feelings, hunches, speculation, and flashes of inspiration prove to be excellent sources of novel approaches, new ways of looking at things, new discoveries, and new information. We do not disparage those ideas derived from religious experience, altered states of consciousness, or the emotions; we merely declare that testing these ideas against reality is the only way to determine their validity as knowledge.
