Why does Humanism have no dogma?
Humanism has no dogma. We have a set of principles that we try to live by, but even those are in flux and change. Every few years, a group of prominent Humanists get together and write a Humanist Manifesto – which sounds a lot like it would be dogmatic, but it isn’t. It’s actually a consensus document. It’s not about what we must believe, but rather about, after much debate, several Humanists agree Humanism is at this point in time.
The current manifesto is Humanism and It’s Aspirations at: http://americanhumanist.org/Humanism/Humanist_Manifesto_III
