nonetheless influential during the 19th century, and its humanism and rejection of supernaturalism are echoed in the works of later authors such as Oscar Wilde, George Holyoake—who coined the word secularism—George Eliot, Émile Zola, and E. S. Beesly. Paine's The Age of Reason, along with the 19th-century Biblical criticism of the German Hegelians David Strauss and Ludwig Feuerbach, also contributed to new forms of humanism. Advances in science and philosophy provided scholars with further alternatives to religious belief. Charles Darwin's theory of natural selection offered naturalists an explanation for the plurality of species. Darwin's theory also suggested humans are simply a natural species, contradicting the traditional theological view of humans as more than animals. Philosophers Ludwig Feuerbach, Friedrich Nietzsche, and Karl Marx attacked religion on several grounds, and theologians David Strauss and Julius Wellhausen questioned the Bible. In parallel, utilitarianism was developed in Britain through the works of Jeremy Bentham and John Stuart Mill. Utilitarianism, a moral philosophy, centers its attention on human happiness, aiming to eliminate human and animal pain via natural means. In Europe and the US, as philosophical critiques of theistic beliefs grew, large parts of society distanced themselves from religion. Ethical societies were formed, leading to the contemporary humanist movement. The rise of rationalism and the scientific method was followed in the late 19th century in Britain by the start of many rationalist and ethical associations, such as the National Secular Society, the Ethical Union, and the Rationalist Press Association. In the 20th century, humanism was further promoted by the work of philosophers such as A. J. Ayer, Antony Flew, and Bertrand Russell, whose advocacy of atheism in Why I Am Not a Christian further popularized humanist ideas. In 1963, the British Humanist Association evolved out of the Ethical Union, and merged with many smaller ethical and rationalist groups. Elsewhere in Europe, humanist organizations also flourished. In the Netherlands, the Dutch Humanist Alliance gained a wide base of support after World War II and in Norway, the Norwegian Humanist Association gained popular support. In the US, humanism evolved with the aid of significant figures of the Unitarian Church. Humanist magazines began to appear, including The New Humanist, which published the Humanist Manifesto I in 1933. The American Ethical Union emerged from newly founded, small, ethicist societies. The American Humanist Association (AHA) was established in 1941 and became as popular as some of its European counterparts. The
