The decade of the 70s, with its emphasis on human potential and the overthrow of authorities, was very congenial to the Humanists in the denomination, too, and by the end of the decade they had a sense that they were the denomination, that the essence of Unitarianism was Humanism, and sometimes even that this was the only legitimate kind of Unitarianism.  However, just as they supplanted the Transcendentalists who supplanted the Christians, they, too, were being slowly supplanted; not so much by any particular theology, but by a post-modern understanding of the multiple nature of truth and the desirability of nurturing religious diversity.
