For your consideration, from the Website of the American Humanist Association, I offer: The Humanist Manifesto I am surprised that none of you, especially you, MtheGM, are familiar with the Humanists. I am told that, for a couple hundred years, the foremost British Meeting was in London, and called the South Place Ethical Society, and continue on to this day as the Conway Hall Ethical Society.

The American Humanist Association website offers this general overview of their ideas:

"Humanism is a progressive philosophy of life that, without theism and other supernatural beliefs, affirms our ability and responsibility to lead ethical lives of personal fulfillment that aspire to the greater good of humanity."
